3.5 Proper location for installing your
heater
Carefully select the location of the water heater. For
safety and for proper heater operation, you must provide
combustion air to the heater and a proper exhaust vent
system.
Follow the guidelines below:
B 1. Locate the heater where venting, gas and
plumbing connections are feasible and convenient.
B 2. The hot water lines should be kept short and
insulated to save energy. Centrally locating the water
heater is recommended to keep hot water
distribution times even throughout the structure.
3.6 Heater placement and clearances
The tankless water heater is approved for
installation on a combustible wall (see
chapter 3.7 Mounting installation) provided the
floor covering below the heater is
noncombustible.
For installations in an alcove or closet, maintain the
minimum clearances to combustible and non-
combustible materials listed below. See also Fig. 7,
page 9.
3.7 Mounting installation
If wall is sheathed with plaster or drywall, it is
recommended that two support boards, either 1"x4" or
½" (minimum) plywood first be attached across a pair of
studs, see Fig. 26, page 26.
B Secure the wall mounting bracket provided with the
heater to a wall surface. The heater must be kept
level on the wall surface, see Fig. 27, page 26.
B Hang the appliance on the bracket, see Fig. 28, page
27.
