HEATER SERVICE Fan and Heater

All Airstream heaters are constructed of durable weather-resistant materials, so a minimum amount of service should be required; however before the unit is started for the first time each season there are a few items that need to be checked out. All damaged parts should be repaired or replaced.

1.Disconnect and lock out power to fan and heater. Open control box lid and inspect all compo- nents for moisture, vibration or rodent damage. Inspect and tighten all loose terminal con- nections. Replace any damaged wiring.

2.Remove burner orifice tube and inspect for dirt

or foreign material. Clean out if necessary.

3.Inspect burner for wear or foreign material in any of the ports. Clean or replace parts if necessary.

4.Inspect the spark plug and flame probe for cor rosion and damage. Clean or replace if necessary.

5.All control boxes and components should be checked yearly for signs of moisture accumulat ion. Any moisture will affect microprocessor con trol system used on this heater. The conduit and control boxes are particularly susceptible and should be checked frequently. Any accumula tion of dirt or foreign material can also cause problems with the electrical system.
