SECTION 11: USER INSTRUCTIONS

11.4.2 To Turn the Heater Off

Set the installed remote controls to the "OFF" position.

The burner will turn off immediately.

The fan will continue to run for a few minutes. To restart, turn the control used above to "ON".

11.5 Simple Fault Finding

Some possible reasons for the heater not operating are:

1.Gas supply not turned "ON".

2.Electricity supply not turned "ON".

3.The time and/or temperature controls are not "ON".

4.The limit thermostat may have operated. This may be caused by an interruption of the electri- cal supply or failure of the distribution fan.

If the limit thermostat persistently operates, there is a fault which must be investigated by a contractor qualified in the installation and service of gas-fired heating equipment.

11.5.1 Simple Fault Finding (Burner Faults)

If the burner fails to ignite for any reason, it will go to lockout. This will be indicated by the red light on the back of the heater or at the remote indicator (if fitted).

1.Press in and release the lockout reset button. If a remote reset is not fitted, a reset button is on the back of the heater.

See Page 5, Section 4.1.

Lockout should not occur during normal operation of the heater and indicates there is a fault condition which must be corrected.

FOR YOUR SAFETY

If you smell gas:

1.Open windows.

2.DO NOT try to light any appliance.

3.DO NOT use electrical switches.

4.DO NOT use any telephone in your building.

5.Leave the building.

6.Immediately call your local gas supplier after leaving the building. Follow the gas supplier’s instructions.

7.If you cannot reach your gas supplier, call the Fire Department.

WARNING

Fire Hazard

Do not store or use petrol or other flammable vapours and liquids in the vicinity of this or any other appliance.

Some objects will catch fire or explode when placed close to heater.

Failure to follow these instructions can result in death, injury or property damage.
