HEATER SERVICE
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.
