4 Technical Data
As long as no threshold values are given, the following
technical data are understood to include tolerances of
±10% usual for heaters at an ambient temperature of
+20° C and at nominal voltage and conditions.
Electrical Components:
Control unit, combustion air fan motor and dosing pump,
g
low plug, control switch and timer are either of the 12 V
or 24 V type.
The components temperature limiter, temperature sensor,
a
nd flame sensor are identical in the 12 V and 24 V units.
