TEST OR INSPECTION
CORRECTIVE ACTION
Step 10. Check for frozen fuel pump. Stop operation. Remove electrical
power. Use screwdriver to free shaft of the fuel pump so it will
turn. If gasoline is used, add one pint of grade 30 motor oil
(item 18, app D) to each 5 gallons of gasoline. If gasoline is used
without adding grade 30 motor oil, the fuel pump will freeze.
Check to see if fuel is leaking in the fuel pump area.
Step 11. Visually check for leaking fuel lines.
2. WATER TOO HOT.
Step 1. Check WATER TEMPERATURE gage on front of heater. If gage
indicates temperatures of 200 F or higher, the automatic control
and safety devices of the water heater are defective.
Shut off heater and notify unit maintenance.
