but always place an nonfl ammable insulation plate, at least
12 mm thick, between the appliance and the rear wall, with
free space on either side of 2 cm. (Total ± 5 cm.)
The rear wall must be made of nonfl ammable material.

Never use combustible materials during the installation.

Ventilate the fi replace, by allowing vents above and
below the fi replace.

During installation of the gas fi re, a clearance of 3 mm
should be maintained on all sides of the appliance to
allow for expansion of the appliance during operation.

Do not insulate the appliance! Only the top and sides
may be fi tted with a strip of white, loose insulation wool
(heat-resistant to 1000°C), width 15 cm max. to protect
the wall.

Do not use fi breglass or Rockwool, or any other sort of

Maintenance consists of the following:

• Remove fi rst the embers, vermiculite granules, logs set or pebbles from the main
burner and carefully clean these with a soft brush.

• Clean and inspect (visually) the main burner, pilot light, combustion chamber,
fl ue system and combustion air intake. Dust can be removed using a vacuum
cleaner.

• Clean the glass on the inside of the appliance with glass spray or ceramic hob
cleaner. This also applies to the black mirror rear wall and side panels, if the
appliance is fi tted with these.

• After cleaning;

Carefully replace the embers, vermiculite granules, logs set or pebbles on and

around the main burner according to the installation directions in this instruction
booklet.

Do not place any embers, vermiculite granules, logs or pebbles against the

pilot light burner. Make sure that the pilot fl ame can burn at all times freely over
the main burner. Only in this way is proper ignition of the main burner ensured.

Ignoring these directions could lead to a dangerous situation.

• Check the gas supply, fl ue system, and combustion air supply route for leaks.

• Check the correct operation of the gas regulator block, thermocouple
circuit and the ignition of the main burner.

• Check the gas inlet-pressure (both when the appliance is off and when it burns
at maximum) and the burner pressure.

• Check if the overpressure hatches are correctly positioned and check if the

packing seals properly under the hatches.

• Check the complete concentric fl ue system including the outlet construction.

A camera can be used to inspect the whole length of the fl ue gas outlet and the

combustion air intake. Also check that all connections are secure.

3 FAULTS

3.1 POSSIBLE REASONS

Possible reasons for the gas fi re going out are:

• The concentric fl ue system is not installed according to one of the methods detailed

in Paragraph 1.6.

• An incorrect “fl ue gas restriction plate” is fi tted.

• The pilot light extinguishes if fumes are not exhausted or are insuffi ciently

exhausted.

• The pilot light is either dirty or defective.

• Insuffi cient gas pressure.

• (Internal) leak of the concentric fl ue system.

• Thermocouple voltage is too low. This is usually caused by insuffi cient heating of the

thermocouple by the pilot light.

• Dirty electrical contacts in the thermo-electrical system; for example, the

thermocouple connection.

• Batteries in receiver or remote control are fl at.

3.2 SAFETY MEASURES IN THE APPLIANCE

3.2.1 Thermo-electric pilot light shut off

The appliance is protected by means of a thermo-electric pilot light shut off in the event
of a gas escape from the main burner.

3.2.2 Over pressure safety system

The appliance is fi tted with a patented safety system, whereby the door will extract any
over-pressure that arises in a controlled way. In this, a spring system briefl y causes the
door to hinge forward a few centimetres. A loud noise can occur.
A safety strip limits the maximum degree to which the door can be tilted.

If an over-pressure situation occurs, the appliance should be thoroughly checked by the
installer.
