5. Secure the water heater to the duct assembly using the screw
provided.
NOTE: See pages 12 and 13 for installing an air intake through
an outside wall when the manufactured home is located over a
basement or crawl space.
SECURING WATER HEATER TO FLOOR AND WALL
(USE METHOD A OR B)
The water heater must be secured to the fl oor and to the wall of the
enclosure.
METHOD A: use the three mounting brackets and screws packaged
in the carton with the water heater. The two small brackets are used to
attach the water heater to the fl oor and the one large bracket is used
to secure the top of the water heater to the wall.
METHOD B: use metal tape also called “plumbers tape” to secure the
water heater to the enclosure. See the fi gure below as reference for
attaching the tape.
Because of installation variances, these brackets can be located at
any points around the circumference of the jacket. When the bracket
locations are determined, use a 1/8 inch SAE drill bit to set a pattern.
Drill only through the outer jacket of the water heater. Then using the
screws provided, secure the bracket to the water heater, fl oor and
wall. See Figure 12.
