Installation of the Appliance

Check that the chimney conforms to the required specifications as previously stated. Examine the condition and carry out any remedial work as necessary, if the flue has been used for solid fuel it should be swept and a smoke test carried out to check that satisfactory smoke clearance has been established. If all the smoke is not drawn into the flue, pre-heat the flue with a blowtorch or similar and re-check. If there is any uncertainty examine for the cause and if necessary seek expert advice.

Gas Supply

BEFORE COMMENCING WORK, TURN OFF ANY APPLIANCES THAT ARE FED BY THE SUPPLY AND ISOLATE THE GAS SUPPLY BY TURNING OFF AT THE SUPPLY

The gas connection to this appliance is made with 8mm o/d rigid or semi rigid tube to a pressure test elbow situated on the L/H side of the burner as shown in Fig 10. It is advisable to provide a means of isolating the gas supply to the appliance for servicing using the isolation cock supplied. Provision is made i.e. knock-out blanks for entry into the box in both L&R hand rear corners and at the L&R hand sides although for ease of installation, it is recommended that the gas feed is made from the left hand side. Any pipe used under the tray must be in rigid tube such as bundy, suitable pieces of bundy are included in the fitting kit to assist the installer.

Where a concealed gas supply is used, the installer is reminded of the requirements of BS 6891 - 1988 dealing with enclosed pipes. The Standard requires that when a gas pipe is fed through a wall, the pipe should be enclosed in a tight sleeve to protect against failure caused by movement and shall be constructed to prevent passage of gas either between the pipe and sleeve or sleeve and wall.

Where a gas supply pipe enters the box in any of the positions stated, the hole around the pipe should be sealed with a silicone sealant or similar to prevent ingress of air into the flue. Permanent sealant e.g. fire cement etc. should not be used as these would prevent removal of the firebox if so required.

Dismantling the fire prior to Installing.

It will be necessary to dismantle the burner from the firebox before installing the box in the opening.

To remove the burner, unscrew the two screws on the front flange of the burner, lift and pull forward.
