Indoor Location
• 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 should be installed by professionals. Improper installation may cause failure
or dangerous conditions such as gas leaking or explosion.
• Water Heater cannot be installed in an UN-VENTED bathroom, bedroom, basement, living
room, closet, outdoor, 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 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 oor clearance, a clearance of 6 inches must be maintained between the
vent pipe and combustible material. A side wall clearance of 6 inches and a top clearance of 12
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 ame retardant wall thimble. Owner must refer to
vent manufacturer’s instructions and specications. Z-Flex information can be found at www.
novaex.com, please refer to page 32 for additional links. 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 oors 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
airow.
• 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 red water heater or any other appliance should not be installed in a space where liquids
which give o ammable 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.
