Combustible/Flammable Materials
Do not store combustible materials, gasoline, or other flammable vapors or liquids near the water heater. If
found, remove these materials immediately.
Air Contaminates
If allowed to contaminate combustion air, products containing chlorine or fluorine will produce acidic conden-
sate that will cause significant damage to the water heater. Read the list of potential contaminates and areas
likely to have these contaminates in Error! Reference source not found, Part 2. If any of these contaminates
are in the room where the water heater is located, or combustion air is taken from one of the listed areas, the
contaminates must be removed immediately or the intake pipe must be relocated to another area.
Ensure the Water Heater Cabinet is Closed
Ensure the water heater cabinet is closed. Tighten the two upper and lower screws to secure it. The cabinet
must be closed while the water heater is running.
Check the Power Source
Make sure the power cord is properly connected. The main power line is connected to the manual switch box
inside the water heater.
Check the Status of the Control Panel
Observe the Control Panel to ensure the water heater is powered on, and to check for any error codes. Clear
any debris from the panel.
Check Exhaust Vent and Intake Pipe Terminations
Verify that the water heater exhaust vent and intake pipe terminations are clean and free of obstructions.
Remove any debris from the exhaust vent or intake pipe openings. If removing the debris does not allow the
water heater to operate correctly, contact your qualified service technician to inspect the water heater and
the vent system.
Check Exhaust Vent and Intake Piping
Visually inspect the exhaust vent for any signs of blockage, leakage, or deterioration of the piping. Inspect the
exhaust vent bracing. Ensure bracing is undamaged and in good condition. Notify a qualified service technician
immediately if any problems are found.
WARNING
Failure to inspect the venting system and have it repaired by a qualified service
technician can result in vent system failure, causing severe personal injury or
death.
