1 Installation instructions
The installation and start-up must be carried out by specialist installers in accordance
with the NBN D51-003 standard.
During installation, have your installer explain how to use, operate and maintain your
appliance. Each appliance is tested, carefully adjusted and sealed in the factory in
accordance with category I2E+ (natural gas) or category I3+ (propane/butane). See
the identification plate for the type of gas for which your appliance is adapted. Any
modifications of the controls by unauthorised persons will invalidate the warranty.
1.1 Choosing a location
Keep the connection between the connection collar and the flue pipe as short and
straight as possible. The minimum distance from the appliance to a flammable wall is
20 cm. Ensure that there are no curtains hanging above the appliance. Combustion
consumes oxygen. It is therefore very important that the space in which the appliance is
installed is adequately ventilated. Install ventilation of at least 15 cm² (not closable).
1.2 Connection to the flue pipe
The flue pipe must comply with the rules described in standard NBN B61-001.
Before connecting the appliance to a flue pipe to which a coal, wood or oil-fired stove
was previously connected, it is best to have the flue professionally cleaned. Although
a gas stove can operate with a very small flue draught, we advise you to have the flue
checked every year. The appliance is connected to the flue using a 100 mm diameter
discharge pipe fitted into the connection collar on the rear wall. Use corrosion-resistant
materials. This connection pipe should never come below the connection collar of the
stove.
Check whether the flue is working correctly by operating the appliance at full capacity
for ten minutes before holding a cold mirror or chromed object to the draught diverter
(behind the appliance below the connection collar). If the mirror or object mists up, the
flue is not functioning sufficiently.
1.3 Connection to the gas supply
Check whether the gas type and the gas pressure correspond to the indications on the
identification plate. An approved AGB/BGV gas valve must be fitted as close as possible
to the appliance.
The connection must be tension-free.
Check that the gas supply pipe has no leaks (e.g. using soapy water).
For pipes up to +/- 10 m in length, 3/8" G tubes or 10/12 diameter copper tubes are
adequate. For more than 10 m use 1/2" or 13/15 diameter copper tubes.
