Installation Manual
WARNING
•
Installation and service must be performed by a qualified installer (for example, a licensed
plumber or gas fitter). Otherwise, the warranty will be void.
•
The installer (licensed professional) is responsible for the correct installation of the water
heater and for compliance with all national, state/provincial, and local codes.
•
The manufacturer does not recommend installing the water heater in a pit or location where
gas and water can accumulate.
•
Do not attach the gas line to the water heater until after the gas line system pressure test for
leaks has been completed. See page 30 for additional information.
• Do not install or locate the vent terminal pointing toward any operating window, door, opening
into a building or other area where people gather, where combustion gases could create a
nuisance or hazard or cause property damage.
• Do not install the air intake next to any source of airborne debris, such as a clothes dryer, that
can cause debris to be trapped inside the combustion chamber, unless the system is direct-
vented.
• Do not install the unit where water, debris, or flammable vapors may get into the flue terminal
or the air intake line.
•
The manufacturer does not recommend installing the water heater in an attic due to safety
issues
. If you install the water heater in an attic:
- Make sure the unit will have enough combustion air and proper ventilation. Failure to do
so could lead to carbon monoxide poisoning or death.
- Keep the area around the water heater clean. When dust collects on the flame sensor, the
water heater will shut down on an error code.
- Place the unit where it will allow easy access for service and maintenance.
- A drain pan, or other means of protection against water damage, is recommended to be
installed under the water heater in case of leaks. See the NOTICE below.
•
The water heater must be securely mounted to a wall or other suitable structure so that it is
level (left-to-right & front-to-back) and plumb (vertically).
•
Failure to observe these warnings could result in severe personal injury, death, and/or
property damage.
NOTICE
•
The warranty will not cover damage caused by water quality.
- Only potable water can be used with this water heater. Do not introduce pool or spa
water, or any chemically treated water into the water heater.
- Introduction of water with iron greater than 0.3 mg/L.
- Water pH levels must be between 6.5 and 8.5.
- Well water must be treated.
•
The manufacturer recommends direct venting when the water heater is installed in beauty
salons, dry cleaners or any other locations in which such chemicals are present in the air.
Some chemicals used in beauty salons or dry cleaners may affect the flame sensor. In such
cases, the water heater may not work properly.
• Although the water heater is designed to operate with minimal sound,
the manufacturer
does not recommend installing the unit on a wall adjacent to a bedroom, or a room that is
intended for quiet study or meditation, etc
.
• Locate your water heater close to a drain where water leakage will not do damage to
surrounding areas. As with any water heating appliance, the potential for leakage at some
time in the life of the product does exist. A drain pan, or other means of protection against
water damage, is recommended to be installed under the water heater in case of leaks. In
addition, you may install an active water leak detector with a shutoff valve which can turn
off the water supply in the event of a leak. The manufacturer is not responsible for damage
due to water leaks. If you install a drain pan under the unit, ensure that it will not restrict the
combustion air flow.
• This water heater is not suitable for combination water (potable) heating, space heating, and/
or recirculation
