Part 13 - 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
