4.5 Mounting instructions
▶ 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. 6.
▶ 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 (½" minimum) first
be attached to the wall surface. The heater must be kept
level on the wall surface.
