This water heater must not be located near ammable liquids
such as gasoline, butane, liqueed propane, adhesives, solvents,
paint thinners, etc., as the controls of this water heater could
ignite these vapors and cause an explosion resulting in property
damage, severe personal injury, or death.
4. If the water heater is to replace an existing water heater, check for
and correct any existing system problems such as:
• System leaks
• Location that could cause the system and water heater to
freeze and leak
• Incorrectly-sized expansion tank
5. This water heater must be installed vertical on a level surface.
C. Water Chemistry Requirements
Chemical imbalance of the water supply may aect eciency and
cause severe damage to the appliance and associated equipment.
Water quality must be professionally analyzed to determine whether
it is necessary to treat the water. Various solutions are available to
adjust water quality. Adverse water quality will aect the reliability
of the system. In addition, operating temperatures above 135
o
F will
accelerate the build-up of lime scale and possibly shorten appliance
service life. Failure of an appliance due to lime scale build-up, low
pH, or other chemical imbalance IS NOT covered by the warranty.
The water must be potable, free of corrosive chemicals, sand, dirt,
and other contaminates. It is up to the installer to ensure the water
does not contain corrosive chemicals or elements that can damage
the heat exchanger. Potable water is dened as drinkable water
supplied from utility or well water in compliance with EPA secondary
