It is also very important to ensure that the fire is not subjected to intermittent flue downdraught, which can blow flames/gas down to the

For Hole In The Wall installations (sunken burners) the fire is supplied with batteries in a separate box that has a long lead which plugs

into a socket on the standard electronics/battery box. This allows the batteries to be placed in an accessible place such as behind the air

If using the extended battery box ensure that any batteries are removed from the electronics box battery compartment. This battery box

is available as an optional extra for other installations, if required. Also available as an optional extra is a mains adaptor to be used

instead of batteries, which again has a long lead which plugs into the socket on the standard electronics/battery box. IMPORTANT –

All electronic equipment is sensitive to dampness and high humidity. The Thermatronic equipment must be installed in a completely dry

place that does not access directly to outside air. If the fireplace has recently been rendered it must be allowed to completely dry out

before the electronic equipment is installed. It is possible that dampness has occurred during storage of the appliance, so as a

precaution we suggest placing the electronic box in a warm dry place for a while before installation.

In common with all other gas appliances, dirt and debris in the gas system can block the valve and gas injectors on this appliance, and

faults caused by this are not covered by the guarantee. Pipework installation must comply with approved standards and practices. If in

doubt as to the cleanliness of site pipework, install a sediment trap, or filter as close to the appliance as possible

red/off button. Wait for another minute and then start the fire as normal. If the fire does not start repeat the resetting procedure. If the fire

Note: If an extended battery box has been supplied, and the lead has been unclipped from the battery box, do not let the lead terminals

touch any metal parts, because voltage is still stored in the capacitors, which can cause a short circuit.

NOTE. On some burners such as the Fireboxx and "sunken" burners it is not possible for the user to access the Receiver Box

to carry out a Full Reset. If the user cannot access the reset button on the Receiver Box a Qualified Installation Engineer will

need to remove the burner to do so and this will involve disconnecting the burner from the gas supply.

If you obtain a new handset the control system will need to learn the handset's unique code via a Full Reset. Also, if the fire is not
