6. Service
All heaters are constructed of durable weather-resistant materials, so a minimum amount of service should
be required. 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/heater. Open control box lid and inspect all components for
moisture, vibration or rodent damage. Inspect and tighten all loose terminal connections. Replace
any damaged wiring.
2. Remove burner orifice tube and inspect for dirt or foreign material. Clean out if necessary.
3. Inspect holes in burner ring for possible corrosion or plugging with dirt or rust. Clean if necessary.
4. Be sure primary air inlet screen is intact and clean for proper burn.
5. Check perforated ring on natural gas models to be sure it is clean and no holes are plugged.
6. Inspect flame probe and ignitor and adjust or replace if necessary.
WARNING
Always disconnect and lock out power before working on or around heater.
