3.2 Mounting the Water Heater to the Wall

Navien water heaters come with an upper mounting bracket that is
pre-drilled at 16 inches on center for easy installation on standard
wall studs. If the strength of the wall is insufficient or if the framing
is non-standard or uneven, reinforce the area before installing the
water heater. Avoid installation on common walls as the unit will
make some operational noises while it is running.
To mount the water heater to the wall:
1. Affix the bracket securely to the wall and ensure that it is level
and that it can support the weight of the water heater.
2. 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" (16mm) clearance from the back of the wall.
CAUTION
Do not mount the water heater to dry wall that has not been
reinforced.
