INSTALLATION INSTRUCTIONS

SITE REQUIREMENTS

1.FLUE AND CHIMNEY REQUIREMENTS

1.1The chimney or flue system must comply with the rules in force, and must be a minimum of 127mm in diameter. (5").

1.2The minimum height of the flue or chimney must be 3 metres (10ft). Any horizontal flue run from the rear outlet should not exceed 100mm from the back of the appliance.

1.3The chimney or flue must be free from any obstruction. Any damper plates should be removed or secured in the fully open position and no restrictor plates should be fitted.

1.4The chimney should be swept prior to the installation of the appliance, but where it can be seen that the chimney is clean and unobstructed throughout its entire length, it need not be swept.

NOTE: If it is intended to fit the stove into an existing brick- built chimney without a closure plate*, a 5" (127mm) liner must be used. Larger lined flues may work, but in some instances could cause cold start flue problems resulting in nuisance shutdown. Lined flues above 7" (175mm) are not recommended.

Due to recent changes to European chimney standards, new flues and chimneys are now described by their temperature, pressure and resistance to corrosion, condensation and fire. To assist in identifying the correct flue system, the minimum flue specification is shown in the Technical Specification in this manual. Existing chimneys are not covered by this system.

1.5*Closure Plate Installation

Small and Medium stoves can be installed into a Standard, fireplace opening with the optional closure plate and spigot extension made for the appliance.

Note the stove and plate will require removing, when carrying out the annual service.

The small Marlborough stove is also approved with a Closure plate for installation into pre-cast letterbox flues conforming to BS 1289:1986. with a minimum flue cross sectional area of 16500mm2 and a minimum dimension of 90mm.

2.VENTILATION

2.1The large stove has a rated output in excess of 7Kw and requires a minimum of 11cm2 permanent effective free air. This is in addition to any window that opens, and although it must communicate with the outside air whenver possible, it can communicate with an adjacent room providing such space has a similar opening to the outside. The small and medium stoves have a rated output below 7Kw and do not normally require any additional ventilation.

3.INSTALLATION OF THE GAS SUPPLY

3.1Before installation, ensure the local distribution conditions (identification of the type of gas and pressure) and the adjustment of the appliance are compatible.

3.2Ensure that the gas supply is capable of delivering the required amount of gas, and is in accordance with the rules in force.

3.3Soft copper tubing and soft soldered joints can be used but must not be closer than 50mm to the base of the tray.

3.4A means of isolating the gas supply to the appliance must be provided, independent of any appliance control.

3.5All supply gas pipes must be purged of any debris that may have entered, prior to connection to the appliance.

4.APPLIANCE LOCATION

4.1This appliance must stand on a non-combustible hearth that is at least 12mm thick, and project a minimum of 50mm from the base of the stove in all directions.

4.2This appliance must not be installed in a room that contains a bath or shower.

4.3The stove is not suitable for installation against a combustible wall; all combustible materials must be removed from the area behind the stove.

4.4The position of the appliance must comply with the minimum clearances forcombustionable materials as shown in diagram 2 and 2A.

In a non-combustible recess, attention must be given to allowing adequate clearance at the sides and rear of the stove, so that a spillage test can be performed, and the controls reached.
