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.
