5.2 General
Warning
Switch off power during maintenance!
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.
5.3 Photocell (Fig. 9)
Check the photocell:
1. Open the doors of the convector heater.
2. Remove the cover of the burner.
3. Pull photocell (A) out of plate (B).
4. Clean the photocell if the glass has turned
black.
If the glass is cracked, the photocell must be
replaced by the dealer.
Reinstall the photocell in reverse order.
