Adjustment
NOTICE!
Before adjustment, first check whether the air inlet flap can
move freely and close tightly (no wedging, no foreign bo-
dies).
Set required flow temperature using the knob. Allow the boiler to
heat up slowly until the set temperature is reached. Arrange the le-
ver arm so that short section with the bore for the chain points to
the front, lies approximately horizontal (dotted line in Figs. 1 and
2) and is positioned as precisely as possible over the chain moun-
ting point.
Secure it in this position by tightening the hexagon screw (2). Make
sure that the hexagon screw bears on a flat surface of the lever arm
and does not press on an edge of the lever arm. Shorten the chain
so that the air flap remains open by about 1 mm when the set tem-
perature is reached.
