Dear Customer,

We are sure your new boiler will comply with all your requirements.

Purchasing one of the CHAPPEE products satises your expectations: good functioning,

simplicity and ease of use.

Do not dispose of this booklet without reading it: you can nd here some very useful

information, which will help you to run your boiler correctly and efciently.

Do not leave any parts of the packaging (plastic bags, polystyrene, etc.) within children’s

reach as they are a potential source of danger.

CHAPPEE boilers bear the CE mark in compliance with the basic requirements

as laid down in the following Directives:

- Gas Directive 90/396/CEE

- Performance Directive 92/42/CEE

- Electromagnetic Compatibility Directive 89/336/CEE

- Low Voltage Directive 73/23/CEE

Instructions prior to installation

This boiler is designed to heat water at a lower than boiling temperature at atmospheric

pressure. The boiler must be connected to a central heating system and to a domestic

hot water supply system in compliance with its performances and output power.

Have the boiler installed by a Qualied Service Engineer and ensure the following ope-

rations are accomplished:

a) accurate purging of the whole pipework in order to remove any deposits.

b) careful checking that the boiler is t for operation with the type of gas available. For

more details see the notice on the packaging and the label on the appliance itself.

c) careful checking that the ue terminal draft is appropriate; that the terminal is not

obstructed and that no other appliance exhaust gases are expelled through the same

ue duct, unless the ue is especially designed to collect the exhaust gas coming from

more than one appliance, in conformity with the laws and regulations in force.

careful checking that, in case the ue has been connected to pre-existing ue ducts,

thorough cleaning has been carried out in that residual combustion products may

come off during operation of the boiler and obstruct the ue duct.

Instructions prior to commissioning

Initial lighting of the boiler must be carried out by a licensed technician. Ensure the

following operations are carried out:

a) compliance of boiler parameters with (electricity, water, gas) supply systems settin-

gs.

b) compliance of installation with the laws and regulations in force.

c) appropriate connection to the power supply and grounding of the appliance.

Failure to observe the above will render the guarantee null and void.

Prior to commissioning remove the protective plastic coating from the unit. Do not use

any tools or abrasive detergents as you may spoil the painted surfaces.

Commissioning

of the boiler

To correctly light the burner proceed as follows:

1) provide power supply to the boiler;

2) open the gas cock;

3) turn the selector switch (1) to set the boiler on summertime (

) or wintertime (

) operation;

4) turn the central heating (12) and domestic hot water (13) adjusting controls in order

to light the main burner.

To increase temperature values turn the control clockwise and anticlockwise to

decrease it.

When on summertime operation (

) the main burner and the pump will start running

only when there is a call for hot water.

Instructions pertaining to the user

ﬁgure 1

020521_0700

Warning: During initial lighting, until the air contained in the gas pipes is not released,

the burner may fail to light immediately and that may cause a ‘blockage’ of the boiler.

Under such circumstances we recommend you repeat the ignition procedure until gas is

delivered to the burner, and briey set knob (1) to (

) (also see gure 4).

Room temperature adjustment

The system must be equipped with a room thermostat (see the relevant regulations) to

control the temperature in the rooms.

In case there is no room thermostat, during initial lighting, it will be possible to control

the room temperature by turning control (12).

To increase temperature values turn the control clockwise and anticlockwise to decrease

it. Electronic modulation of the ame will enable the boiler to reach the set temperature

by adapting the gas supply to the burner to the actual heat exchange demand.

DHW temperature

adjustment

The gas valve is provided with an electronic ame-modulating function, which operates

depending on the DHW temperature adjusting control (13) settings and on the quantity

of water drawn from the taps.

This electronic device allows to keep the water coming out of the boiler at a constant

temperature also when small quantities of water are drawn.

To increase temperature values turn the control clockwise and anticlockwise to de-

crease it.

Filling the boiler

Important: Regularly check that the pressure displayed by the pressure gauge (14) is

0.7 to 1.5 bar, with boiler not operating. In case of overpressure, open the boiler drain

valve (Figure 3b).

In case the pressure is lower open the boiler lling tap (Figure 3a).

We recommend you open the tap very slowly in order to let off the air.

During this operation, the Summer/Winter selector (ref. 1, gure 4) must be in the OFF

position (0)

In case pressure drops occur frequently have the boiler checked by a Qualied Service

Engineer.

Figure 3a

Figure 3b

The boiler is supplied with a hydraulic differential pressure sensor, which blocks the boiler

in case water is lacking or the pump is blocked.

Turning off the boiler

The electric supply to the boiler must be removed in order to switch it off. When the

selector (1) is in position (0) the boiler stays off, but the voltage remains present in the

electric circuits of the apparatus.

Prolonged standstill of the system

Frost protection

(central heating system)

We recommend you avoid draining the whole system as water replacements engen-

der purposeless and harmful limestone deposits inside the boiler and on the heating

elements.

In case the boiler is not operated during wintertime and is therefore exposed to danger of

frost we suggest you add some specic-purpose anti-freeze to the water contained in the

system (e.g.: propylene glycole coupled with corrosion and scaling inhibitors).

The electronic management of boilers includes a ‘frost protection’ function in the central

heating system which operates the burner to reach a heating ow temperature of 30° C

when the system heating ow temperature drops below 5°C.

The frost protection function is enabled if:

* electrical supply to the boiler is on;

* the gas service cock is open;

* the system pressure is as required;

* the boiler is not blocked.

Gas change

These boilers produced for natural gas can be converted to work with LPG.

Any gas change must be effected by a Qualied Service Engineer.

The following remarks and instructions are addressed to Service Engineers to help them

carry out a faultless installation. Instructions regarding lighting and operation of the boiler

are contained in the ‘Instructions pertaining to the user’ section.

Note that installation, maintenance and operation of the domestic gas appliances must be

performed exclusively by qualied personnel in compliance with current standards.

Please note the following:

This boiler can be connected to any type of double- or single feeding pipe convector

plates, radiators, thermoconvectors. Design the system sections as usual though

taking into account the available output / pump head performances, as shown on

page 50.

* Do not leave any packaging components (plastic bags, polystyrene, etc.) within

children’s reach as they are a potential source of danger.

Initial lighting of the boiler must be effected by a Qualied Service Engineer.

Failure to observe the above will render the guarantee null and void.

Instructions prior to installation

This boiler is designed to heat water at a lower than boiling temperature at atmospheric

pressure. The boiler must be connected to a central heating system and, on models

withis option, to a domestic hot water supply system in compliance with its performances

and output power.

Before connecting the boiler have the following operations effected:

careful checking that the boiler is t for operation with the type of gas available. For

more details see the notice on the packaging and the label on the appliance itself.

b) careful checking that the ue terminal draft is appropriate; that the terminal is not

obstructed and that no other appliance exhaust gases are expelled through the same

ue duct, unless the ue is especially designed to collect the exhaust gase coming

from more than one appliance, in conformity with the laws and regulations in force

careful checking that, in case the ue has been connected to pre-existing ue ducts,

thorough cleaning has been carried out in that residual combustion products may

come off during operation of the boiler and obstruct the ue duct.

To ensure correct operation of the appliance and avoid invalidating the guarantee, observe

the following precautions

Hot water circuit

if the water hardness is greater than 20 °F (1 °F = 10 mg calcium carbonate per litre of

water) install a polyphosphate or comparable treatment system responding to current

regulations

Heating circuit

2.1. new system

Before proceeding with installation of the boiler, the system must be cleaned

and ushed out thoroughly to eliminate residual thread-cutting swarf, solder and

solvents if any, using suitable proprietary products

2.2.

existing system:

Before proceeding with installation of the boiler, the system must be cleaned

and ushed out to remove sludge and contaminants, using suitable proprietary

products

To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-

acid and non-alkaline (e.g. SENTINEL X400 and X100), proceeding strictly in accordance

with the maker’s directions

Remember that the presence of foreign matter in the heating system can adversely affect

the operation of the boiler (e.g. overheating and noisy operation of the heat exchanger)

The template to ﬁx the boiler on the wall

Decide upon the boiler location, then tape the template on the wall.

Connect the pipework to the gas and water inlets prearranged on the template lower

bar.

We suggest you t two G3/4 stop cocks (available on demand) on the central heating

system ow and return pipework; the cocks will allow to carry out important operations

on the system without draining it completely.

If you are either installing the boiler on a pre-existent system or substituting it, we

suggest you also t settling tanks on the system return pipework and under the boiler

to collect the deposits and scaling which may remain and be circulated in the system

after the purge.

When the boiler is xed on the template connect the ue and air ducts (ttings supplied

by the manufacturer) according to the instructions given in the following sections.

When installing the 2.24 CF model boiler with natural draught, make the connection to the

ue using a metal pipe which will provide resistance over time to the normal mechanical

stresses, heat and the effects of the combustion products and any condensation they

form.

We guarantee ease and exibility of installation for a gas-red forced draft boiler thanks

to the ttings and xtures supplied (described below).

The boiler is especially designed for connection to an exhaust ue / air ducting, with

either coaxial, vertical or horizontal terminal. By means of a splitting kit a two-pipe system

may also be installed.

...coaxial ﬂue - air duct (concentric)

This type of duct allows to disengage exhaust gases and to draw combustion air both

outside the building and in case a LAS ue is tted.

The 90° coaxial bend allows to connect the boiler to a ue-air duct in any direction as it

can rotate by 360°. It can moreover be used as a supplementary bend and be coupled

with a coaxial duct or a 45° bend.

(*) The restrictor must be removed in case the ue duct length exceeds 1 m.

If the ue outlet is placed outside, the ue-air ducting must protrude at least 18mm out

of the wall to allow alluminium weathering tile to be tted and sealed to avoid water

leakages.

Ensure a minimum downward slope of 1 cm towards the outside per each metre of

duct length.

A 90° bend reduces the total duct length by 1 metre.

A 45° bend reduces the total duct length by 0.5 metre.

… separated ﬂue-air ducting

This type of ducting allows to disengage exhaust ue gases both outside the building

and into single ue ducts.

Comburant air may be drawn in at a different site from where the ue terminal is lo-

cated.

The splitting kit consists of a ue duct adaptor (100/80) and of an air duct adaptor.

For the air duct adaptor t the screws and seals previously removed from the cap.

The restrictor must be removed in case you install separated ue and air duct termi-

nals.

The 90° bend allows to connect the boiler to ue-air ducting regardless of direction as it

can be rotated by 360°. It can moreover be used as a supplementary bend to be coupled

with the duct or with a 45° bend.

L max = 12 m

Separated vertical ﬂue terminals installation options

Important: if tting a single exhaust ue duct, ensure it is adequately insulated (e.g.: with

glass wool) wherever the duct passes through building walls.

For detailed instructions concerning the installation of ttings refer to the technical data

accompanying the ttings.

Split

ﬂue air control adjustment

The adjustment of this control is required to optimise performance and combustion param-

eters. The air suction coupling can be rotated to adjust excess air according to the total

length of the ue and intake ducts for the combustion air.

Turn this control clockwise to increase excess combustion air and anticlockwise to

decrease it.

The maximum length of the suction duct must be 10 metres.

If the ue duct exceeds 6 m, the condensate collection kit (supplied as an accessory)

must be tted close to the boiler.

To improve optimisation a combustion product analyser can be used to measure the CO

contents of the ue at maximum heat output, gradually adjusting air to obtain the CO

reading in the table below, if the analysis shows a lower value.

To properly install this device, also refer to the technical data accompanying the tting.

Separated horizontal ﬂue terminals installation options

IMPORTANT: Ensure a minimum downward slope of 1 cm toward the outside per each

metre of duct length.

In the event of installation of the condensate collection kit, the angle of the drain duct

must be directed towards the boiler.

Gas change modalities

A Qualied Service Engineer may adapt this boiler to operate with natural gas (G. 20) or

with liquid gas (G. 30, G. 31).

The procedure for calibrating the pressure regulator may vary according to the type of

gas valve tted (HONE

YWELL or SIT; see gure 12).

Carry out the following operations in the given sequence:

A) substitute the main burner injectors;

change the modulator voltage;

C) proceed with a new max. and min. setting of the pressure adjusting device.

A) Substitute the main burner injectors

• carefully pull the main burner off its seat;

• substitute the main burner injectors and make sure you tighten them fast to avoid

leakage. The nozzle diameters are specied in table 2.

Change the modulator voltage

• remove the 2 screws securing the control board cover and hinge it upward;

• set the jumper or the switch, according to the type of gas used, as described in the

chapter on page 52.

C) Pressure adjusting device setting

• connect the positive pressure test point of a differential (possibly water-operated)

manometer to the gas valve pressure test point (Pb) (Figure 12); connect, for sealed

chamber models only, the negative pressure test point of the manometer to a “T”

tting in order to join the boiler adjusting outlet, the gas valve adjusting outlet (Pc)

and the manometer. (The same measurement can be carried out by connecting the

manometer to the pressure test point (Pb) after removing the sealed chamber front

panel);

If you measure the pressure of burners by different means you may obtain an altered

result in that the low pressure created in the sealed chamber by the fan would not

be taken into account.

C1) Adjustment to rated output

• open the gas tap and rotate knob (1) to set the boiler to the Winter setting ( );

• open a hot water tap to reach a minimum 10 l/minute ow rate or ensure that maximum

heating requirements are set;

•

remove the modulator cover;

• adjust the tube brass screw (A) Fig. 13 to obtain the pressure settings shown at table

1 on page 51;

• check that boiler feeding dynamic pressure, as measured at the inlet gas valve

pressure test point (Pa) (Figure 12) is correct (30 mbar for G.30, 37 mbar for G.31,

20 mbar for natural gas);

C2) Adjustment to reduced heat output

• detach the modulator feeding cable and unscrew the (B) Fig. 13 screw to reach the

pressure setting corresponding to reduced heat output (see table 1 on page 51);

• connect the cable again;

• t the modulator cover and seal.

C3) Final checks

• apply the additional dataplate, specifying the type of gas and settings applied.

• Central heating temperature adjustment potentiometer

This potentiometer sets the central heating ow max. temperature. Its temperature

range goes from 30 °C min. to 80 °C max.

To increase the temperature turn knob (12) clockwise and anticlockwise to decrease

it.

• Domestic hot water temperature adjusting potentiometer

This potentiometer sets the domestic hot water max. temperature. Its temperature

range goes from 35 °C min. to 55 °C max according to the water inlet ow rate.

To increase the temperature turn knob (13) clockwise and anticlockwise to decrease

it.

• Air pressure switch for forced draft models (2.24 FF)

This switch allows the main burner to switch on provided the exhaust ue duct

efciency is perfect.

In the event of one of the following faults:

• the ue terminal is obstructed

• the venturi is obstructed

• the fan is blocked

• the connection between the venturi and the air pressure switch is not active

the boiler will stay on stand-by and the light (4) will ash.

• Overheat thermostat (2.24 CF)

Thanks to a sensor placed on the heating ow, this thermostat interrupts the gas ow

to the main burner in case the water contained in the primary system has overheated.

Under such conditions the boiler is blocked and relighting (briey rotating selector

(1) to position (

) will only be possible after the cause of the anomaly has been

removed.

It is forbidden to disenable this safety device

• Flame ionization detector

The ame sensing electrode, placed on the right of the burner, guarantees safety of

operation in case of gas failure or incomplete interlighting of the main burner. Under

such conditions the boiler is blocked. Rotate selector (1) briey to position (

) to

restore normal operating conditions.

• Hydraulic pressure sensor

This device enables the main burner only to be switched on if the system pressure

is over 0.5 bars.

•

Supplementary running of the pump

The electronically-controlled supplementary running of the pump lasts 3 minutes,

when the boiler is in the central heating mode, after the burner has switched off due

to a room thermostat or intervention.

• Frost protection device (central heating system)

Boilers electronic management includes a “frost protection” function in the central

heating system which operates the burner to reach a heating ow temperature of

30°C when the system heating ow temperature drops below 5 °C.

This

function is enabled when the electrical supply to the boiler is on, the gas supply

is on and the system pressure is as required.

•

Pump-blocking prevention

In case there is no call for heat either from the central heating system for 24 hours

on end the pump will automatically switch on for 10 seconds.

This function is enabled if the electrical supply to the boiler is on.

• Hydraulic safety valve (heating circuit)

This device is set to 3 bar and is used for the heating circuit.

The safety valve should be connected to a siphoned drain. Use as a means of draining

the heating circuit is strictly prohibited.

Check of combustion parameters

The boiler has two connection points specically designed to allow technicians to

measure the combustion efciency after installation and ensure that the combustion

products do not constitute a health risk, as required by Italian Presidential Decree n.

412 of 26

August 1993.

One connection point is connected to the ue gas discharge circuit, and allows monitoring

of the quality of the combustion products and the combustion efciency.

The other is connected to the combustion air intake circuit, allowing checking of any

recycling of the combustion products in case of coaxial pipelines.

The following parameters can be measured at the connection point on the ue gas

circuit:

• temperature of the combustion products;

• oxygen (O2) or carbon dioxide (CO2) concentration;

• carbon monoxide(CO) concentration.

The combustion air temperature must be measured at the connection point on the air

intake circuit, inserting the measurement probe to a depth of about 3 cm.

For natural draught boiler models, a hole must be made in the ue gas discharge pipe at

a distance from the boiler equal to twice the inside diameter of the pipe itself.

The following parameters can be measured through this hole:

• temperature of the combustion products;

• oxygen (O2) or carbon dioxide (CO2) concentration;

• carbon monoxide (CO) concentration.

The combustion air temperature must be measured close to the point where the air

enters the boiler.

The hole, which must be made by the person in charge of operating the system when it

is commissioned, must be sealed in a way which ensures that the combustion product

discharge pipe is airtight during normal operation.

Output / pump head performances

This is a high static head pump t for installation on any type of single or double-pipe

heating systems. The air vent valve incorporated in the pump allows quick venting of

the heating system.
