2.2 Installation Warnings
WARNING
DO NOT use this water heater for any purpose other
than heating water.
Read, understand, and follow the Installation & Operation
Manual , including all warnings and precautions, before
operating this water heater. If you do not follow these
instructions exactly, a fire or explosion can result, causing
property damage, personal injury, or loss of life.
Follow all local codes and the most recent edition of the
National Fuel Gas Code (ANSI Z223.1/NFPA 54) in the USA
or the Natural Gas and Propane Installation Code in Canada
(CSA B149.1).
This water heater must be installed by a licensed plumber,
gas fitter, or professional service technician. Installation by
unqualified person(s) voids the warranty.
This water heater is designed for operations at outlet
temperature(s) not in excess of 190°F (88°C).
DANGER
A. This water heater does not have a pilot light. It is
equipped with an ignition device which automatically
lights the burner. Do not try to light the burner
manually.
B. BEFORE OPERATING, smell all around the water
heater area for gas. Be sure to smell near the floor
because some gas is heavier than air and settles on
the floor.
WHAT TO DO IF YOU SMELL GAS:
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any phone in
your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire or
police department.
C. Use only your hand to turn the manual gas shut-off
valve. Never use tools. If the manual gas shut-off
valve does not turn by hand, don’t try to repair it.
Call a qualified service technician. Force or attempted
repair can result in a fire or explosion.
WARNING
DO NOT use or store flammable liquids around the water
heater, including gasoline, oils, spray paints, etc.
DO NOT operate this water heater unless it is properly
vented to the outside (the exhaust vent piping must be
connected from the unit directly to the outside). Improper
venting can cause a build-up of carbon monoxide, which
can result in brain damage or death. Exhaust gases must
be completely expelled out of the building.
This water heater is factory preset for NATURAL
GAS but can be field-converted for use with propane.
For propane conversion, refer to the Propane (LPG)
Conversion section of this manual. Connecting the
water heater to any other gas supply can result in
property damage, serious injury, or even death.
This water heater is suitable for use in potable water
heating applications. The cold and hot water fittings on
the top of the water heater MUST NOT be connected to
any heating system.
The water heater temperature is factory set to 120°F
(49°C). Hot water temperatures above 125°F can cause
severe burns instantly or death from scalds. If the
proposed water heater outlet temperature is to be set
above 125°F, installation of a thermostatically controlled
(or temperature-limiting) mixing valve is recommended
for all hot water going to faucets to avoid the risk
of scalding. Examples include commercial applications
where 140°F (60°C) is often needed or if the space
heating temperature required is higher than the domestic
hot water. Always check the temperature of the hot
water before bathing, showering, washing, etc.
Protect against snow and debris accumulation around
the vent terminations. Regularly inspect the exhaust
vent pipe and the air intake pipe to ensure they remain
clear from obstructions at all times.
