Part 12 - Maintenance
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.
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.
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 ame,
etc.) away from the faucet. If hydrogen is present, there will
be a sound of air escaping as water begins to ow. 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.
It is extremely important that whenever work is performed on
the plumbing system that either:
• The water heater is powered o, or,
• The water heater is valved o and isolated from the
plumbing system.
Failure to take these measures could result in a dry-ring
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 o
the water heater or isolating the water heater through the
use of shut-o valves could result in a condition referred to
as “dry-ring”. Dry-ring 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.
Periodic maintenance should be performed once a year by a
qualied service technician to assure that all the equipment
is operating safely and eciently. The owner should make
necessary arrangements with a qualied 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.
