1.1 Warnings
This outdoor kit includes:
• Supports (2) with screws
• Sealing gasket
• Control panel shield
• Outdoor vent cap.
Danger: The top of the outdoor kit will
get very hot during operation. Keep
away from children. Install heater in a
location where the top of the kit cannot
be reached by small children.
Danger: Flue gas will be released
through the outdoor kit. Flue gas is very
hot and contains carbon monoxide. The
outdoor kit cannot be installed on a
water heater mounted indoors. To
prevent risk of fire and carbon monoxide
poisoning, maintain all clearances
indicated in these instructions.
Danger: Do not place or store any
combustible material within 5 feet of the
appliance. Maintain specified clearance
to combustibles on the wall where the
appliance is installed and any adjacent
walls or overhang. Observe all
clearances required in this manual.
Danger: Surface temperature of the kit
is less than 140°F, except highest top
surface which may reach 300°F.
Warning: Do not mount water heater
directly onto vinyl siding, see Fig. 10.
Danger: the freeze prevention kit on
the appliance is designed to provide
protection from temperatures down to
approximately 5°F for short term
conditions only. It will not protect the
appliance in areas where the
temperature is routinely expected
to be below freezing. The freeze
prevention kit will not protect plumbing
outside the appliance from freezing.
Precautions must be taken:
BAlways drain the water heater if it will
be exposed to long term freezing
conditions.
Danger: the water in this appliance is
cold and always remains cold except for
the times when the burner is on. In the
event of power outage in conjunction
with freezing temperatures, it is
recommended that the heater be
drained.
Warning: Damage to the appliance
from freezing is not covered under the
manufacturer's warranty.

2 Selecting heater location
Before proceeding, read the water heater installation
manual. If the information in that manual is not followed
exactly, a fire, explosion or poisoning by carbon monox-
ide may result causing property damage, personal injury
or death.
BThis appliance is not designed to be installed
outdoors in climates that commonly fall below
freezing (32°F).
BChoose an outside wall for the installation. Installa-
tion on a wall protected by an overhang above is rec-
ommended.
BSize the water and gas connections according to the
instructions in the water heater installation manual.
Use unions when connecting both water lines and
gas supply line to the heater.

If the appliance is installed under an overhang, there
must be a minimum 36” clearance from the top of the
appliance and the mounting area must be open in front
and on the sides of the appliance.

Mounting instructions
4 Mounting instructions
BThe water heater is approved for installation directly
on an outside wall. Secure the wall mounting bracket
provided with the water heater to a wall surface. See
Fig. 9.
BThe installation method of the mounting bracket will
depend on the type of mounting surface. Due to the
varieties of building siding or surfacing, the installer
must decide how best to support and level the heater
on an outside wall. It is recommended that horizontal
or vertical support boards or plywood sheathing (1/
2” minimum) first be attached to the wall surface. The
heater must also be kept level on the wall surface.
Fig. 9 Installation on wood siding
Fig. 10 Installation on vinyl siding
Warning: Do not mount heater directly
to vinyl siding.
With vinyl siding, a 3½' x 4' area of the
siding must first be removed and then
replaced with wood or other non-plastic
material. See Fig. 10.
