Heater Maintenance - CHIEF Goldwell CH1015T-NGE/NGEM Installation And Operation Manual

Heater Maintenance

The following procedures should be followed and maintenance performed before starting the unit at the
beginning of every season, and also during operation:
1. The fuel line strainers should be taken out and cleaned. A plugged screen will restrict the gas
flow to the unit. On liquid propane units, liquid and vapor line strainers both should be
checked. Warranty is void if the strainer or screen is removed, and not reinstalled after cleaning.
2. The burner should be checked for obstructions and debris. To check, use a piece of wire or drill
bit that will fit the holes in the burner. To clean the inside of the burner, remove from the
heater and tap lightly around the burner. Then pour the foreign material out of the inlet.
3. The air switch inlet screen should be cleaned. This screen keeps debris from entering the air
switch; however, during operation the screen can become clogged or dirty.
4. Check all plumbing joints for leaks using the "soap test." The gas tightness of the gas train
should be checked at least on an annual basis.
5. Check all wires to verify they are not bare or causing a short. Pests can destroy insulation on
wires, including the spark plug, flame probe, burner limit wires if protective measures to control
rodents are not implemented.
6. Examine and gap spark plug. Through wear, the spark plug can go out of adjustment. Verify
during operation every two days. The gap of the plug should be 1/8" (.32cm).
7. The flame probe needs to be checked to be sure that it has not been burnt off due to lack of
proper adjustment in and out of the flame. The flame probe can also become damaged. Verify
every two days during operation and replace or adjust as needed.
8. Check all wire connections to be sure they are tight.
9. All external plenum controls (nylon humidistat or thermostat combination) should be inspected,
cleaned, and checked every three days during operation.
10. Caldwell recommends that external plenum controls be removed and stored in a clean, dry place
when not in use.
11. Check adjustment of the vaporizer twice daily, or as changing weather conditions demand.
