PART 11 - MAINTENANCE
In unusually dirty or dusty conditions, care must be taken to keep water heater cabinet door in place at all times. Failure to do so VOIDS
WARRANTY!
Allowing the water heater to operate with a dirty combustion chamber will hurt operation. Failure to clean the heat exchanger as needed
by the installation location could result in water heater failure, property damage, personal injury, or death. Such product failures ARE
NOT covered under warranty.
Hydrogen gas can build up in a hot water system served by this water heater that has not been used for a long period of time (generally
two weeks or more). When opening a hot water faucet in a system that has been out of use for a time, keep all ignition sources
(electrical appliances, open flame, etc.) away from the faucet. If hydrogen is present, there will be a sound of air escaping as water
begins to flow. Allow the water to run for a few minutes to dissipate built up hydrogen from the system. Failure to follow these
instructions can result in property damage, personal injury, or death.
The water heater requires minimal periodic maintenance under normal conditions. However, in unusually dirty or dusty conditions,
periodic vacuuming of the cover to maintain visibility of the display and indicators is recommended.
Periodic maintenance should be performed once a year by a qualified service technician to assure that all the equipment is operating
safely and efficiently. The owner should make necessary arrangements with a qualified heating contractor for periodic maintenance of
the heater. Installer must also inform the owner that the lack of proper care and maintenance of the heater may result in a hazardous
condition.

Connections Check wire connections. Make sure they are tight.
Smoke and CO
detector Verify devices are installed and working properly. Change
batteries if necessary.
Circuit Breakers Check to see that the circuit breaker is clearly labeled.
Exercise circuit breaker.
CHAMBER/BURNER
Combustion Chamber Check burner tube and combustion chamber coils. Clean
according to maintenance section of manual. Vacuum
combustion chamber. Replace any gaskets that show signs
of damage.
Spark Electrode
Clean. Set gap at ¼”. Clean probe with plumbers cloth to
remove oxides.
Flame Probe Check ionization in uA (d7 on status menu in Start-up
Procedures). Record high fire and low fire. Clean probe with
plumbers cloth to remove oxides.
CONDENSATE
Neutralizer Check condensate neutralizer. Replace if necessary.
Condensate hose Disconnect condensate hose. Clean out dirt. Fill with water
to level of outlet and re-install. (NOTE: Verify the flow of
condensate, making sure that the hose is properly
connected during final inspection.)

3.5” to 14” W.C.)
Pressure Drop Measure drop in
pressure on light off (no more than 1” W.C.)
Check gas pipe for
leaks Check piping for leaks. Verify that all are properly supported.
