1.8 USING THE APPLIANCE FOR THE FIRST TIME
The gas fire is coated with a lacquer layer resistant to high temperature.
During the first hours of operation, the burning in of the lacquer may result in an
unpleasant smell. This is harmless, however. Operating the gas fire at full capacity for a
few hours, while ventilating the room, will eliminate the smell. Moreover, deposits may
form on the inside off the glass; these can be removed with a dry cloth when the gas fire
has cooled down.
1.9 DAILY MAINTENANCE
• Regulary check that the air supply is still open.
• Ensure that as little dust, and as few particles of cigarette smoke, candles and
oil lamps as possible pollute the air in the room in which the appliance is used.
Heating of these particles by the convection system of the appliance could lead to
discoloration of the walls and ceiling. It is therefore very important to ensure that the
room in which the appliance is located is sufficiently ventilated. Regularly remove any
dust deposits from behind the control flap by means of a vacuum cleaner.
Important: If the glass is broken or cracked, it must be
immediately replaced before operating the
gas !re again.
• If anything is spilt on the fire, switch it off immediately and wait for it to cool down
sufficiently before cleaning. Never use scouring powder, aggressive cleaners or fire
polish on the gas fire. Use only a dry lint free cloth.
• Heat resistant lacquer in aerosols can be obtained from your distributor.
During the yearly maintenance, the lacquer can be used to repair small areas of
damage.
The installation must only be carried out by a
“Gas Safe Register” registered installation engineer.

2 INSTALLATION INSTRUCTIONS
2.1 GENERAL
The gas fire must be positioned and connected as a “open” appliance by a “Gas Safe
Register” registered gas installation engineer in accordance with the following instal-
lation instructions, nationally and locally applicable regulations (see “Technical Details/
Regulations” at the rear of this manual).
If you have any queries regarding the installation, please consult your local gas
company.
If an existing chimney is to be used, please consult your installer first. If the chimney
was previously used for a wood or coal fire, then it should be cleaned by an expert.
A chimney draw of approximately 5 Pa (=0,05 mbar) is sufficient for full load of the
appliance. If the chimney draw is more than 20 Pa (=0,2 mbar), then it is recommended
to reduce it.
Before beginning the installation, check that the details on the rating plate
correspond to the gas type and pressure to which the appliance will be connected.
2.2 FLUE PROTECTION
The appliance is supplied with a security system T.T.B. It is a thermostat which shuts off
the pilot light and main burner under any of the following circumstances:
• insufficient chimney draw.
• under-pressure in the house due to a mechanical exhaust system.
• bad connection between the appliance and the flue.
• partial or total blockage of the flue, for instance, due to falling debris.
• insufficient external air supply in an entirely closed house.
• flue down draught due to wind.
After the problem has been rectified, the appliance can be put back into operation. It
is not permitted to bypass the security system. Always call your installer in case of any
problem.
Replace the security system only with parts identical to those originally supplied!
