Basic construction
Installation and mounting of the gas
filter
The gas filter may be installed in any
desired position. Take care only to
observe the direction of flow of the gas
(arrow on filter housing). Make sure
there is adequate clearance to facilitate
the removal of the cover and
replacement of the filter cartridge.
Filter replacement
The filter cartridge should be replaced
by a new one as soon as a high pressure
drop is noticed. If a new filter cartridge is
not at hand it will be possible to wash the
filter mat in 40°C water adding some
light-duty detergent. Allow the mat to dry
before reinstallation.
NOTE: For the installation of the filter
mat take care to observe the marking or
sticker.

Test burner
Depending on the country-specific
requirements, when installing steam
boilers it may be necessary to fit a test
burner to the gas train (e.g. in line with
directive TRD 412). This is used to vent
the gas pipes. The gas supply is
switched on by pressing the button (1).
The flow of gas brings in the required
amount of combustion air via the hole in
the body (3). The gas/air mixture is
routed towards the burner head (4) and
ignited manually at its opening. Gas is
supplied for as long as the button is
pressed and cut off when it is released.
