MOUNTING ON THE BOILER
REMOVAL OF FAN HOUSE UNIT
FROM BURNER.
Loosen the screws. Swing out the fan
house. Remove the ionisation and ig-
nition cables from the electrodes. Re-
move the bolt on the flange.
Removethecombustionunitfromthe
burner. Fit the enclosed flange and
gaskettotheboiler.Ifnewfixingholes
must be drilled, use the fixing flange
as a pattern.
REMOVAL OF VALVE UNIT FROM
BURNER
Remove the plug-in contact from the
multi-bloc. Loosen the union nut.
172 205 42 94-01
INSTALLATION EXAMPLE
Connect the gas to the burner by
means of the ball valve. Ensure that
the union nut, ball valve and tubing
makeiteasytoremovetheburnerfor
inspection and service.

Acontrolismade that the air pressure switch does not indicate fan pressure. Then the
burnermotorstarts.
2Air damper motor opens.

switch indicates sufficient fan pressure.
3Air damper motor closes.
The air damper motor closes to low load . Then the ignition spark is formed.
4Mainandsafetyvalvesopen
The gas is ignited. The ionization electrode indicates a flame.
5Thesafetytimeexpires.
The ignition spark goes out. The safety time expires. If there is no flame or if for some
reason the flame disappears after this time limit, the burner control locks out.
