Mounting instructions

4.4
B The 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. 13.
B The 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 on 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.

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. 14.
