This appliance has been designed, tested and manufactured to EN613 with references to British Standard BS
7977-1:2009 Class 1 & 2 relating to Radiant Convector Gas Appliances and must be installed by a qualified Gas
Safe Registered Installer in accordance with the Gas Safety (Installation and use) regulations 1994 and all other
relevant standards. This appliance is intended for use on a gas installation with a governed meter.
This appliance must be connected in accordance with the National Regulations. The appliance must be sealed
into a non-combustible fireplace whose only opening must be through a Class I (7” or 175mm diameter) or Class
II (5” or 125mm diameter) chimney / flue of at least three metres in height.
Before installation, ensure that the local conditions, (identification of gas type and pressure) and the adjustment
of the appliance are compatible. Base temperatures of this appliance are quite low so it can be placed directly
onto timber or laminate flooring. However, due consideration should be taken if installing directly onto materials
such as deep pile carpets or similar combustible materials, in these circumstances a non-combustible hearth of
12mm minimum thickness should be used. This hearth should extend by 50mm minimum in all directions from
the stove base.

This fire is a very effective heating appliance and must be fitted against a wall of non-combustible material as
classified in BS 476-4:1970 (2007).
All parts of the appliance become hot while running and should therefore be considered to be working surfaces.
An air vent is not required for this application. The appliances have been tested without the need for additional
air requirements.
We recommend that if the chimney/flue has been used for solid fuel, it is swept prior to installation of this
appliance and that any flue restrictor or damper plate should be removed.
The chimney/flue must always generate a positive up draught to ensure safe operation.
The installer must then establish that all the products of combustion are entering the flue within ten minutes of
lighting from cold. This can be verified by inserting a lit smoke match into the central duct immediately below the
stove top panel. It should NOT be inserted into the left and right convector ducts. (see ‘Spillage Test’ page 6).
An isolation valve must be fitted adjacent to the appliance. When closed, this will allow the complete burner and
control assembly to be disconnected for maintenance or repair in accordance with national regulations.
The gas supply should be provided by a semi rigid pipe with an 8mm diameter and should be no longer than 1.5
metres in length.
OTE: When the gas supply pipe is passed through masonry or other brickwork always ensure that the end
of the pipe is covered to avoid any debris passing through into the appliance controls.
The appliance is fitted with an Oxygen Depletion Sensor (ODS) that monitors the room for products of
combustion. If products are detected, the ODS will automatically shut down the appliance. If this situation
arises, re-light the appliance, referring to the user instructions (page 14).
If shut down re-occurs, a qualified person must be called to thoroughly check the appliance. The spillage
monitoring system (ODS pilot) must not be put out of operation or be tampered with or adjusted by either the
installer or the user. If the unit is found to be at fault it should be replaced with the manufacturers original
replacement parts.

Debris collection space for class one chimneys using closure plate
A debris collection space should be provided at the base of a flue unless it is lined or constructed of flue blocks,
or is a factory made metal chimney with a flue box. This can be achieved by providing a space having a volume
of not less than 12 litres and a depth of at least 150mm below the point where flue gases discharge into the
chimney. The space should be readily accessible for clearance of debris, for example by removal of the
appliance.
If the Debris Deflector Panel LEG-DDP01 is to be used, this must be installed into Class 1 brick constructed
chimneys only and having a cross sectional area of not less than 52,258mm sq (9”x9”).
The deflector panel should be fixed to a register plate of a minimum size of 776mm wide x 440mm deep. The
height from the register plate up to the intersection with the flue should be not less than 150mm.
The cut-out size in register plate to accommodate the Debris Deflector Panel should be 360mm long x 215mm
wide.
The installer shall confirm that the chimney is in good condition and has passed a flue performance test before
the appliance can be installed with the flue kit.
The following warning attached to the deflector panel should also be observed:
WAR I G: This appliance is installed to an unlined chimney. For examination of the debris void and condition of
the chimney, refer to the appliance manufacturer’s instructions or remove the whole firebox.

1. This fire is a natural gas appliance and has been designed for use with the following applications:
a) Class I - Conventional brick or stone chimney as used for a solid fuel fire with a cross sectional dimension of
225mm x 225mm (9” x 9”) or a lined flue with a minimum diameter of 125mm (5”), with the fireplace components
conforming to BS1251, or a standard builders opening a minimum of: 560mm (22”) high and 406mm (16”) wide
with a minimum depth of 100mm (4”) to allow sufficient volume for debris collection (unlined chimney 12 dm3and
lined 2 dm3). Any permanent flue restrictions or variable dampers are to be removed or locked in the fully open
position. The chimney should also be swept prior to installation.
b) Class II - An insulated flue (twin wall) having a minimum diameter of 125mm (5”) and a minimum effective
overall height of 3 metres (10’).
OTE: If the fire is to be used with an existing brick or stone chimney, a 125mm (5”) minimum diameter flue
liner conforming to BS715 may be used.
2. Care should be taken to prevent any damage being caused to surrounding soft furnishings or decoration, e.g.
many embossed vinyl wall coverings may become discoloured if placed too close to the appliance.
3. A suitable proprietary fire surround with 100°C rating may be used with a minimum clearance from the top of the
stove to the underside of shelf of 225mm, providing that the depth of shelf is 150mm or less. It is recommended
that combustible materials are not placed adjacent to this appliance unless shielded with a fire resistant surface
25mm minimum thickness.
FLUE FLOW TEST
A flue flow test (smoke test) is carried out to check the effectiveness of the flue and to ensure that there is no
leakage into another part of the premises (including any loft), or as appropriate other adjoining premises (this is
particularly important where a number of chimneys combine into a multiple stack).
The flue flow test should be carried out using a suitable smoke pellet which the pellet manufacturer claims to
generate 5m3of smoke in 30 seconds burn time.
These gas fires should have the flue flow test carried out with the appliance in position but not connected to the
gas supply so that the smoke test can be carried out with representative flue flow conditions.
A warm flue will be more effective than a cold flue. If the flue is reluctant to draw, which can be initially assessed
by lighting a smoke match at the intended position of the appliance flue connection, introduce some heat into the
flue for a minimum of 10 minutes using a blow torch or other means.
Other factors, such as weather conditions and a combination of materials used to construct the flue can all
influence the flue draught. The pre-heating process may require as much as half an hour before the flue behaves
satisfactory as a blow torch does not represent the volume of heat consistent with the normal appliance operation.
A Flue Flow Test should be checked as follows:
1. Carry out those visual checks as indicated previously, and continue only if satisfactory.
2. Establish that an adequate air supply is available for the combustion of the appliance
3. Close all doors and windows in the room that the appliance is to be installed.
4. Light a smoke pellet at the intended position for the appliance. Place the inset fire case into position.
5. The test is satisfactory if:
- there is no significant escape of smoke from the appliance position.
- there is no seepage of smoke over the length of the flue.
- smoke is discharged only from the correct terminal.
VE TILATIO
No special ventilation bricks or vents are required in the room containing the appliance, providing that normal
adventitious room ventilation exists. The installer must determine this by carrying out a spillage test.
SPILLAGE TEST
To check for satisfactory clearance of products of combustion, close all doors and windows and leave the fire
burning on high setting for a minimum of ten minutes. The left and right hand ducts are for convection only. The
central duct above the glass door has a visible hexagonal post in the middle, this post indicates the approximate
depth to place a lit smoke match. All the smoke must be drawn into the flue. If spillage occurs, allow a further ten
minutes and repeat the test. Should spillage still occur turn the appliance off and seek expert advice. To continue
the test: If an extractor fan is situated in the room the test should be repeated with the fan running. If there is a
connecting room with an extractor fan the test should be repeated with all the doors to that room open and the
extractor fan running.
