The thermosticker is used to measure
the operating temperature of the burner
body in a certain area. The temperature
measurements provide indirect informa-
tion regarding the condition of the heating
system and the need for preventive action
or maintenance of the burner and exhaust
ducts.
For example: a high temperature of the
burner may indicate a high ash deposit.
Once the normal operating conditions are
restored, the thermosticker returns to its
normal colour (black).
The burner thermosticker must be checked
on a regular basis, and after any mainte-
nance procedures carried out on the boiler
and/or burner operating with pellets.
The thermosticker indicates an overheat-
ing of the pellet feed tube.
The activation of this thermosticker may
occur if the flue gases flow into the pel-
let tube due to a greater resistance of
the exhaust pipe and/or decrease in the
chimney draft.
In these cases, the flexible connection
tube between the screw feeder and burner
body could be damaged.
When activated, the thermosticker can not
return to its initial condition. Replace the
thermosticker once the normal operating
conditions are restored.
Viewing of the sticker in the initial condi-
tion: if the active segment is white, the
temperature has not reached the activation
level (104°C).
Viewing of the sticker in the initial con-
dition: if the active segment is dark, the
temperature has exceeded the activation
level (104°C).
