MAINTENANCE
5.1
Maintenance table
Use the table in this booklet to record performed
maintenance after each winter season.
5.2
General
Use the table in this booklet to record performed
maintenance after each winter season.
When the convector heater is to be stored for a
longer period of time:
1. Switch on the convector heater for three
minutes. This will protect the fuel pump
against corrosion.
2. Make sure the burner head is free from dust
and deposit.
A dirty heater head will cause insufficient
combustion, resulting in the development of
soot and carbon monoxide and causing
damage to the burner room.
3. Close the valve of the fuel supply.
4. Disconnect the power plug.
Warning
Switch off power during maintenance!
Hot
Do not touch the flue and air outlet!
Wait until the flue and the air outlet have
cooled down sufficiently before carrying
out any maintenance.
