22 Installing the Boiler
3.2 Mounting the Boiler to the Wall
Navien NCB300 boilers come with an upper mounting bracket
that is pre-drilled at 400 mm 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 boiler. Avoid installation on party walls as the unit
will make some operational noises while it is running.
To mount the boiler 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 boiler.
2. Align the grooves on the back of the boiler with the tongues
on the mounting bracket and hang the boiler on the
bracket.
When mounted with the mounting bracket, the boiler will
have a 16 mm clearance from the back of the wall.
WARNING
●
The boiler is heavy. Always lift the unit with assistance. Be
careful not to drop the boiler while lifting or handling it
to avoid bodily injury or damage to the unit.
●
Do not rest the boiler on the bottom end after removing
it from the shipping carton. Doing so may result in
excessive pressure on protruding pipes and result in
product damage. If you must put the boiler down, lay it
on its back or put it inside the protective shipping base.
DANGER
●
The boiler must be mounted on a suitable wall that can
support its weight and prevent explosion or fire.
●
Do not install the boiler near paper or other flammable
objects.
●
Do not install the boiler near domestic waste.
Note
●
You need to install a Stand Off Kit to pipe up the
back of boiler.

Refer to the instruction manual provided with
Stand Off Kit.
