WARNING
Disconnect the electric power during
maintenance!
When you store the heater for a long period:
1. Let the heater burn for 3 minutes. This protects
the pump against corrosion.
2. Keep the burner head free from dust and sedi-
ment. A dirty burner head causes bad combustion
that makes soot and carbon and damage to the
burner chamber.
3. Close the valve for the fuel supply.
4. Disconnect the electric power.
