Installation distances may vary by local code. It is the installer’s responsibility to verify installation
requirements.
•
Make sure before installation that the gas type you will use is the same type on the data plate.
•
The water heater unit should be installed by professionals. Improper installation may cause failure
or dangerous conditions such as gas leaking or explosion.
•
Failure to have the water heater installed by a professional will void your warranty.
•
The water heater cannot be installed in an un-vented bathroom, bedroom, basement, living room,
closet, outdoors, laundry room, stairway or an exit area. If installed in an exit area, it must be at
least 16.5 ft. or more away from the exit.
•
Vent pipe should extend from the wall at least 2”. The terminal must be at least 1.64 ft. away from
obstruction and must be well vented.
•
Vent pipe should slope 3° downward to avoid condensing water and protect from rain entering.
•
Vent pipe should avoid direct, strong wind because the downdraft will cause malfunction.
•
The water heater should be installed far from any blockage, and with plenty of enough space for
installation and maintenance. Adequate clearances for servicing must be provided.
•
The water heater should not be installed in the same room with a gas stove.
•
When determining the floor clearance, a clearance of 6 inches must be maintained between the
vent pipe and combustible material. A side wall clearance of 10 inches and a top clearance of 16
inches must be maintained.
•
The vent pipe can be up to 32 ft. in length with one elbow.
•
The vent pipe should be installed with a flame-retardant wall thimble. Owner must refer to vent
manufacturer’s instructions and specifications. Installation guidelines for venting provided by
NovaFlex, who is solely responsible for venting installation accuracy.
•
The power socket connecting the water heater should be grounded properly with a GFCI circuit
protector.
•
The water heater should not be located in an area where leakage of the heat exchanger or
connections will result in damage to the area adjacent to it or to lower floors of the structure.
When such areas cannot be avoided it is recommended that a suitable catch pan, adequately
drained, must be installed under the water heater. The pan must not restrict combustion airflow.
•
This unit MUST NOT be installed in a laundry room or in the same room as the washer/dryer.
Installation of the unit in a laundry room or in the vicinity of a washer/dryer will void the warranty.
•
The water heater should be installed as close as practical to the vent termination to minimize vent
length and the number of elbows required for venting.
•
A gas fired water heater, or any other appliance should not be installed in a space where liquids
which give off flammable vapors are to be used or stored. Such liquids include gasoline, LP gas
(butane or propane), paint or adhesives and their thinners, solvents or removers.
•
The water heater should be installed far from heat sources, flammable and dangerous materials.
Because of natural air movement in a room or other enclosed space, flammable vapors can be
carried some distance from where their liquids are being used or stored. The open flame of the
water heater’s main burner can ignite these vapors causing an explosion or fire which may result in
severe burns, death or property damage.
