THREE GOOD REASONS

Why you should have your stove commissioned.

It is vital for the longevity and efﬁcient and safe operation of the stove to have the stove installed and

commissioned by a competent qualiﬁed heating engineer.

1. Installation

The stove should be installed by a competent qualiﬁed heating engineer, who will be conversant with the

Building Regulations and Codes of Practice current at the time of installation. Installation instructions are

supplied with the stove which contain instructions speciﬁc to the appliance.

Incorrect installation may lead to poor performance of the stove and ultimately damage to the appliance.

2. Operating

The operation of the stove should be demonstrated by a competent person, so you, as the operator, are

conversant with the operation of the controls. Instructions on the use of the controls can be found in the

operating instructions supplied with the stove.

Incorrect operation of the controls of the stove may lead to poor performance from the stove and ultimately

damage the appliance.

3. Maintenance

Routine maintenance as described in the operating instructions, supplied with the stove, should be

undertaken by a competent person.

Failure to perform the routine maintenance may adversely effect the performance of the stove and

ultimately damage the appliance.

Registration Form

To be completed by both the owner of the stove and the installing/

commissioning engineer.

It MUST be returned to Euroheat for the registration to be completed.

Hearth and Fireplace Requirements

Do not be tempted to ﬁt the stove into an unsuitable ﬁreplace. Beyond the requirements

of the building regulations and access to facilitate servicing the stove, providing a

setting which will complement the stove is not a luxury, it is the practicality of making

the most of an investment. A good builder will be able to transform even the most

utilitarian of ﬁreplaces, whether altering its proportions to those of the “Golden Mean”

ideal, exposing a wooden lintel, stone or simply removing superﬂuous detailing for

comparatively small costs, and the result will be a pleasure for many years.

Appliance Location

a) In a ﬁreplace recess the stove can be mounted on a 12mm thick decorative hearth or plinth, if

a constructional hearth of the correct dimensions is in place. In a free standing situation, as the

hearth temperature does not exceed 100ºC, a constructional hearth is not required. The stove

can be mounted on a 12mm thick non-combustible decorative hearth of the correct size i.e. a

cast iron plinth, provided that the ﬂoor can support the weight.

b) Combustible material at the rear of the stove shall be protected against the effects of heat.

c) There must be a minimum of 300mm from the top of the stove to the underside of any combustible

shelf. Note that for every 50mm increase on clearance, the shelf may project by a further 50mm.

d) The appliance, being room sealed, may be installed in a room or space which will be used by the

occupants for sleeping.

e) Any manufactured surround used with this stove should comply with the appropriate British Standard.

f) Do not place furniture, furnishing or combustible objects within 1 metre of the stove.

If any of these conditions are not fulﬁlled,

DO NOT FIT THE STOVE until this has been rectiﬁed.

Installation of the Gas Supply

BS 6891

NOTE:

Ensure that the gas supply is capable of delivering the required amount of gas, and is in accordance with

the relevant current standards.

It is generally preferred to conceal the gas supply by bringing it under the hearth, or through masonry to the

side of the ﬁreplace. Any pipe work in 8mm tube connecting the stove to the main pipe work should be kept

as short as possible with as few ﬁttings as possible to prevent restrictions.

a) Whenever a gas pipe passes through any masonry it must have a sleeve of non combustible material

sealed at both ends to prevent the gas supply from coming in contact with masonry or lime based

mortars.

b) The gas pipe should be adequately supported over longer lengths.

c) Soft copper tubing and soft soldered joints are suitable, providing the tube is not closer than 150mm

to the stove casing i.e. the temperature must not exceed 100°C.

d) A means of isolating the gas supply to the appliance must be provided independent of any appliance

control. This may be a gas cock, ideally of the nursery type to prevent children interfering with the

gas supply.

e) Any gas tubing that has been passed through masonry, should be purged to expel any foreign

materials that may have entered the supply.

f) Care should be taken to ensure that pipe work brought through metal structures has been secured to

prevent chafﬁng, but allow for thermal expansion.

Flue Spigot Fitting

The ﬂue can be either top or rear exit. The ﬂue collar (spigot) is supplied attached to the pallet on which the

stove is delivered or within the body of the stove. It will need ﬁtting to the stove depending on which ﬂue kit

you are using, rear exit can only be used on the rear to horizontal low-level ﬂue kit.

Fitting Top Flue Spigot

The stove comes with the inner top ﬂue pipe adapter ﬁtted to the stove with a choke plate ﬁtted below it, see

picture below. Ensure that the choke plate ﬁtted is correct for the gas type and ﬂue conﬁguration to be installed,

this information is in the Balanced Flue Stove Technical Guide: IN1105, page 24. If not replace with the correct

choke plate which can be found in the bag of installation accessories.

Inside the stove in the bag of installation accessories will be the ﬂue spigot gasket and two M5 screws to ﬁt the

cast iron spigot. Fit the gasket as shown above and then attach the ﬂue spigot using the two screws.

Fitting Flue Spigot and Inner Adapter Pipe

to the Rear of the Stove.

1) Remove the inner adapter pipe, see above, and

choke plate from the top of the stove. The choke plate

is not required for the rear ﬂue option.

2) Remove the cast iron blanking plate from the rear of the stove.

3) Loosen the four screws on the inner steel blanking plate on the rear of the stove. Twist the blanking plate

so that the plate lifts over the screws.

4) Align the inner ﬂue adapter pipe with the screws and twist it so it locks into position. Tighten the four screws

to ensure a good seal.

NOTE:

Do not ﬁt the choke plate to the

rear outlet as it will restrict the

air ﬂow and stall the ﬂue gasses

and the stove will not work.

Installation of the Flue System

All the information regarding the three types of ﬂue kits can be found in the Euroheat Balanced Flue Technical

Guide, Document No: IN1105.

IMPORTANT

To the Installer, Please Read Prior

To Installation

There have been a number of reports of stoves giving

off an unpleasent smell after the curing process has

ﬁnished. In most cases it has been found that some form

of Mastik has been used to join the ﬂue pipes together

and to the ﬂue spigot (collar) on the stove.

Some of these so called “Heat Proof” mastiks will only

stand a temperature of 300°C before they start breaking

down. In many cases they may give off an obnoxious

smell at temperatures much lower than this.

Please ensure that the jointing compound used is

suitable, if in doubt contact the manufacturer of the sealing compound before you use it.

We would advise the use of Fraxﬁll on all ﬂue joints and for all fuel types, available from your Euroheat dealer

or directly from Euroheat.

Installation of the Gas Log Effect

If any of the components of the log effect or burner are broken DO NOT INSTALL . Contact your stove supplier

for replacements. The log effect kit is not covered by the stoves warranty for accidental damage, so great care

should be taken when handling the ceramic burner and logs. It is important that the logs and ember ﬁbres are

installed in accordance with these instructions as any deviation may cause poor combustion. The addition of

further ceramic logs or coals is strictly prohibited.

Do not compress the embers or force into

position.

Placement of the Ember Glow Fibres

Platinum ember glow ﬁbres are for use in vented gas appliances only. Platinum ember glow ﬁbres are made from

high grade ceramic wool. The wool is similar to ﬁbreglass and should be handled carefully. We recommend the

use of suitable dust mask, gloves or tweezers when placing the embers in position. Wash hands immediately

after touching to avoid irritation. Do not store the embers close to ﬂammable liquids.

The embers must be placed correctly in order

to function properly. Tease out the fabric to

form loose, irregular shapes.

Ember Glow Fibres Placement

In front of burner jets

To left side of burner jets

By rubbing embers into the faces of the logs which are heated by the gas jets, the ﬁbres which adhere to the

logs will glow. With suitable gloves take a square of ember glow and gently rub the material into the areas of

logs which glow when in operation (see the log ﬁtting instructions which follow).

The pack containing the ember glow ﬁbres contains more than required. The additional embers should be kept

for further service requirements.

Use of embers

With the embers correctly placed they glow and ﬂicker similar to glowing ash. Their placement is important as

the effect produced can only occur when they are heated by the gas jets or by direct radiated heat.

1. Fit the largest log with the hole and slot in the base corresponding to the peg and tongue at the back of the

ceramic burner, ensuring that the peg goes into the hole on the log and the tongue goes into the slot. Place

2-3 pieces of teased out ember glow ﬁbres (A) just to the left hand side of the burner jets. Place 3-4 pieces

of teased out ember glow ﬁbres (B) just to the right hand side of the burner jets. Place 6-7 teased out ember

glow ﬁbres (C) just in front of the burner jets.

Note: if not teased out or placed over the burner jets, ﬂame height will be greatly reduced.

2. Fit the second largest log with the one hole in the base locating it on the peg in the middle of the ceramic

burner. Place 6-7 ember glow ﬁbres (D) just in front of the burner jets.

3. Fit the right hand log (E) with the “V” corresponding to the two indentations, in the burner base at the right

hand end of the front log. The other end of the log resting upon the back log. Fit the left hand log (F) with the

knot corresponding to the indentations, at the left hand end of the front log. The other end of the log resting

Installation of the Gas Coal Effect

If any of the components of the coal effect or burner are broken DO NOT INSTALL . Contact your stove supplier

for replacements. The coal effect kit is not covered by the stoves warranty for accidental damage, so great care

should be taken when handling the ceramic burner and coals. It is important that the coals and ember ﬁbres

are installed in accordance with these instructions as any deviation may cause poor combustion. The addition

of further ceramic logs or coals is strictly prohibited.

The Set of Coal Pieces

The Burner

17

The front coal, the second largest of the coals, when turned upside down will be seen to have one circular

indentation corresponding with a raised locator on the burner. Place the front coal so that the locator ﬁts into

the coal and gently position the coal until its shaped underside ﬁts snugly into the undulations of the burner.

When ﬁtted correctly the back and front coals will look

like this.

Turning over the back coal piece, the largest of the set, will reveal a round hole and an oblong hole. These

correspond to the round and square peg and raised locators on the burner. Position the back coal so round and

oblong locators ﬁt snugly into the corresponding holes in the back coal.

When ﬁtted the back coal should be positioned on the

burner to look like this.

E & OE Instructions Part number IN1159 Ed F

18

Place the third largest coal so that it rests on the burner, against and overhanging the coal in front. It is formed

to engage with the coal in front to ﬁx its lateral position.

Finally the last two small coals can be put in the positions as below.

With the coals in position a small amount of Ember glow that has been teased carefully into very loose shapes

can be added. It should be put over the jets of the burner in front of the front coal

19

Gas Connection

a) Connect the gas supply pipe to the 8mm connection under the base of the appliance. We advise that

no more than 1 meter of 8mm pipe is used to connect from the 15mm gas feed.

b) Connect a suitable gas pressure gauge to the test nipple on the gas valve, see page 21, turn the gas

supply on and check that the gas connections are sound. If satisfactory light the appliance.

Check all the gas connections on the appliance for leaks. The appliance is factory tested, but it is

possible for a connection to have been disturbed during transportation and installation.

c) Set the control to the high setting, and check that the gas pressure is as stated on the data table.

d) Turn off the gas, remove the pressure gauge and reﬁt the test point screw, turn the gas supply

on and check that the test nipple is gas sound.

Lighting

Ensure the pipe work has been purged prior to following the lighting procedure.

Turn the on/off knob, smaller right hand control knob, towards the ignition position and press and turn anti-

clockwise. There will be an audible click as the Piezo spark is generated. If the pilot lights hold down the control

knob for 30 seconds, if it has not lit then repeat the pilot lighting procedure to maximum of 6 attempts. If after

6 attempts the pilot has not ignited leave the appliance for 5 minutes before attempting again.

Once the pilot has been established, let out the control knob and turn it fully anti-clockwise.

Manual Control

Turn the larger left hand control anti-clockwise to increase, clockwise to decrease the desired heat output.

Ensure that the main burner lights within 3 seconds.
