Location
This water heater is for OUTDOOR
installation ONLY!
This water heater is an outdoor model
and must be mounted on a vertical wall.
It must not be installed indoors or in a
confined space. The water heater should
be installed close to the mose frequently
used outlet and its position chosen with
safety and service in mind.
Make sure people (particular children,
disabled, and elderly) will not touch the
hot water outlet or the flue terminal.
The flue terminal and air inlet must be
clear of obstruction and shrubbery.
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.
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.
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.
The water heater must be located so it is
not subject to physical damage, for example,
by moving vehicles, area flooding, etc.
● The water heater must be installed
vertically with the water, gas, and
power connections on the underside,
pointing toward the ground.
● Failure to properly install the water
heater outdoors as outlined in this
manual can result in unsafe operation.
● Hot and cold water lines should be
insulated to conserve water and energy.
● The water heater and water lines should
be protected from exposure to freezing
temperatures.
● Do not install water heater where
subject to vibrations.
● Do not install the water heater in
Recreational Vehicles, Mobile Homes,
Boats and other Watercrafts.
● Do not install the water heater near
vents for heating or cooling. A
minimum of 4 feet should be
maintained.
● Minimum clearance from combustible
construction is 1/2” sides, 0” rear (with
support bracket); 12” from the bottom;
12” from the front of the water heater;
and 12” from the top (24” from front
and top is recommended for servicing
purposes). If the clearances stated on
