INSTALLATION INSTRUCTIONS

Mounting the Water Heater

CAUTION:

Reinforcement of the wall is required where the wall is not

strong enough to hold the water heater. Failure to do so

could result in personal injury and/or property damage.

The mounting location for the water heater should allow

for easy access and operation.

The water heater is designed to be installed either inside

the wall cavity between the wall studs or outside the

wall cavity. Either installation requires the water heater

to be supported with a wooden support brace between

the wall studs, or a piece of wood that is equal in size to

the water heater and securely attached to the wall studs

before the water heater is attached to it. This piece of

wood can be installed inside or outside of the wall. Use

wood screws to secure brackets to wall. If mounting to a

concrete wall, use lag bolts designed for concrete.

Make sure the proper electrical outlet or supply (120

VAC/60 Hz) is available and located near the unit. Direct-

vent models come with a 6-ft. (1.8-m) power cord, while

the outdoor models require hard-wiring or the addition

of a plug.

Attach the mounting bracket to the wall and secure it by

4 screws and washers. Make sure it is level and that it

can support the weight of the water heater.

NOTICE:

The image above may differ in appearance from your water

heater.

Align the grooves on the back of the water heater with

the tongues on the mounting bracket and hang the

water heater on the bracket. When mounted with the

mounting bracket, the water heater will have a 5/8" (16

mm) clearance from the back of the wall. Using two

screws and washers , secure the lower mounting bracket

to the wall.

NOTICE:

DO NOT connect power until venting installation is complete

(see Venting installation).
