6.1 Annual Maintenance
The Webasto heater requires a minimum of maintenance to operate.
To keep your Webasto heater in good working order, the following maintenance procedures should be performed
annually before each heating season:
Enclosure Area
- clean the heater and enclosure area of any accumulated debris or dust with compressed air.
- inspect all components for wear and damage.
Electrical System
- check all wiring harnesses for damage and corrosion, repair or replace if required.
- check the condition of the batteries and the connections.
- load test the batteries and replace if necessary.
NOTE
For major repairs and service parts, return to your authorized Webasto Thermosystems Specialist.
Exhaust System
- check the exhaust system carefully for restrictions or corroded areas. Replace worn or damaged exhaust
components as necessary.
Fuel System
- replace the fuel filter (prime) and inspect the fuel line for wear and damage. Repair or replace if necessary.
Burner System
- swing open the burner head, clean the flame detection (photo eye), pull out the combustion chamber, inspect
and clean the inside area of the heat exchanger. Replace the fuel nozzle if necessary (annually). Reinstall
the combustion chamber and close up the burner head.
Operational Check
- Run your heating system for at least 15 minutes.
- Check all water and fuel connections for leakage. Check tightness of all hose clamps if necessary.
NOTE
The heater will not function properly or to your satisfaction with weak batteries.
NOTE
Operate your Webasto heater at least once a month for 10 minutes.
CAUTION
Annual maintenance requires basic product knowledge and maintenance procedures and should only be performed
by Webasto trained and certified, skilled personnel. Ask your Webasto representative about training clinics.
