Maintenance Procedures
2.
The water heater must be inspected and serviced annually, preferably at the start of the heating season, by a qualified service
technician. In addition, the maintenance and care of the water heater as outlined in this manual must be performed by the user/
owner to assure maximum efficiency and reliability. Follow the maintenance procedures given throughout this manual. Failure to
perform the service and maintenance or follow the directions in this manual could damage the water heater or system components,
resulting in substantial property damage, severe personal injury, or death.
To prevent the potential of substantial property damage, severe personal injury, or death, eliminate all the materials listed in Table
1 from the area surrounding the water heater and the vicinity of the combustion air intake. If contaminates are found:
● Remove products immediately from area.
● If contaminates have been there for an extended period, call a qualified service technician to inspect the water heater for
possible damage from acid corrosion.
If products cannot be removed, immediately call a qualified service technician to re-pipe the combustion air intake piping away
from the contaminated areas.
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 condensate that will cause
significant damage to the water heater. Read the list of potential contaminates and areas likely to have these contaminates in
Table 1. If any of these contaminates are in the room where the water heater is located, or combustion air is taken from one of
the areas listed, 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.
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.
