Heater Maintenance
The Webasto Air Top 5000 heater is designed for minimal maintenance. Under normal circumstances it should be
inspected for proper function at least once annually, perferrably, just prior to the heating season.
To ensure trouble-free operation, the following should be part of an annual and periodical inspection:
1. Operate the heater a minimum of 10 minutes every month to keep fresh fuel in the system and the fuel pump
lubricated.
2. Keep the heating air outlet and ducting clear of obstructions. Inspect outlet ducting for damage and repair as
necessary.
3. Keep the heater inlet grille clear of obstructions. If the heater is equipped with ducting, inspect for damage and
repair as necessary.
4. Inspect the combustion air tube and exhaust tube for obstructions and damage. Check to ensure they are securely
attached to the heater and vehicle. Repair damaged items where necessary.
5. Inspect the fuel system and all connections for leaks. Tighten clamps if loose. Ensure fuel line is well secured to the
vehicle. Replace fuel filter if equipped.
