Part 14 - 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 the 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. The installer must also inform the owner
that the lack of proper care and maintenance of the heater may
result in a hazardous condition.

It is extremely important that whenever work is performed on the
plumbing system that either:
• The water heater is powered off, or,
• The water heater is valved off and isolated from the plumbing
system.
Failure to take these measures could result in a dry-firing condition.
The water heater must be full of water and the system fully purged
BEFORE powering the water heater. Performing any work in the
plumbing system without either powering off the water heater or
isolating the water heater through the use of shut-off valves could
result in a condition referred to as "dry-firing". Dry-firing the water
heater will damage the heat exchanger, and could result in property
damage, serious personal injury, or death. Such damages ARE NOT
covered by water heater warranty.
