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) This stove must be mounted on a non combustible hearth. The hearth must have a minimum of

12mm non combustible material thickness. The stove can be placed on a wooden ﬂoor if it can

support the weight and as long as the hearth plinth is utilized.

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.

10

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. 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.

12

5) Fit the spigot gasket and ﬂue spigot to the rear of the stove.

6) Fit the rear inner blanking plate to the top of the stove, see picture below. The stove will not run if this

part is omitted.

7) Fit the gasket and rear blanking plate onto the top ﬂue exit using the countersunkscrews. If it has an

enamel ﬁnish the cup washers should also be used to protect the enamel ﬁnish.

Installation of the Flue System

All the information regarding the three types of ﬂue kits can be found in the Euroheat’s 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, ember glow

ﬁbres and ember cubes are installed in accordance with these instructions as any deviation may cause poor

combustion. The addition of further ceramic logs or cubes is strictly prohibited.

Pilot Ignition Route

Do not compress the embers or force into

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.

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. Once the

burner has been lit the embers may need adjusting to give the required effect.

The pack containing the ember glow ﬁbres contains more than is required.

The additional embers should be kept for further service requirements.

Important:

tease out fabric to form

loose, irregular shapes.

16

Fitting the Log Effect Kit

This is very fragile and should be handled with the utmost care. Ensure that all transport packaging which held

the ceramic burner in place in transit has been removed.

Position the main log at the rear of the burner, so that the ﬂat surfaces of the rear log and burner sit

together.

1. Place ceramic cubes adjacent to the holes of the burner underneath the rear log with teased out sections

of ember glow under each ember cube, leaving about 5mm between each cube. Do not place ceramic cubes or

ember glow on the pilot ignition route (see previous page). Gently rub the ember glow into the burnt surfaces

of the log.

2. Fit the left hand log with the larger end on the burner and the smaller end against the rear log. There is

a small groove next to the left circular secondary air hole. The left log has a chamfered edge which should be

located into this groove. Gently rub the ember glow into the burnt surfaces of the log.

Left log ﬁts into groove in

burner surface

17

3. Fit the front log. In the centre of the burner is a groove for the front log to be located. Gently rub ember

glow into the burnt surfaces of the log.

Place ceramic ember cubes along the holes of the burner in front of and to the sides of the right hand log, with

teased out sections of ember glow under each ember cube, leaving about 5mm between each cube.

18

4. Place the front log in the front locating slot in the burner surface, then lean the log against the left log.

The ceramic cubes may have to be adjusted to allow the front log to sit correctly.

The ceramic log effect burner should NOT be used if damaged in anyway.

Do not be tempted to try to mend the ceramic log effect burner, always replace it.

The ceramic log effect burner sits lightly on top of the gas input venturi tube, do not push the burner

hard down onto it as this may crack the ceramic log effect burner.

When the appliance is ﬁrst ﬁred small adjustments to the ceramic cubes and ember glow can be made to

achieve the desired effect.

19

Gas Connection

Harmony 45 (H45)

Connect a 15mm gas supply pipe to the 3/8” connection at the rear of the appliance. We advise that a

minimum supply pipe size of 15mm is utilized, (8-10mm supply pipe is not suitable).

Harmony 35 (H35)

Bring a 15mm gas supply pipe as close as possible to the appliance connection, use an 8mm pipe for the ﬁnal

connection. Do not use more than 500mm of 8mm ﬁnal connecting pipe.

Connect a suitable gas pressure gauge to the test nipple on the gas valve, see page 18, 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.

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

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

For full operating instructions see operation manual.

Turn the on/off knob, smaller right hand knob, slightly counter-clockwise towards the ignition position until the

control knob stops turning, press it down and hold for 5 seconds to allow the gas to the pilot light.

After 5 seconds turn the control to the pilot position with the knob still depressed. There will be an audible click

as the Piezo spark is generated. Hold down the control knob for 30 seconds if the pilot has lit, 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. (This assumes the system has been purged)

Once the pilot has been established, let out the control knob and turn it anticlockwise to the “ON” position.
