7) Select a location that ensures the water heater will have sufficient clean, combustion
air; avoid installation where dust or debris will accumulate; avoid installation where
chemical agents (e.g., hair spray, spray detergent, chlorine, chemicals) are used;
8) If installing into a very tight space or corner, please ensure there is sufficient service
and maintenance access to all gas and water piping to ensure that regular
maintenance (such as cleaning the water filter, the air filter and the condensate trap)
will not become problematic;

Top of Heater
Back of Heater
Front of Heater
Sides of heater

9) DO NOT install in an area that contains or stores gasoline or other flammables.
10) Ensure that combustibles are clear of the immediate area. Ensure hanging laundry
or other such items will not impede the air movement into, or out of, the water heater
or its venting.
11) For commercial applications, avoid greasy fumes or a large amount of steam; take
measures to prevent the fumes and steam from entering in the equipment;

Mounting the Unit to the Wall:

1. All Navien units come with an upper mounting bracket pre-drilled at 16" on
center for easy installation on standard stud walls. Affix the bracket to the wall
securely, ensuring that it is level and that is can support the weight of the
water heater. If the strength of the wall is not sufficient, reinforcements must
be made to prevent unsafe situations.
2. If the framing is not standard, reinforment of the wall is required or if installing
on an uneven surface, fasten %" plywood to the stud wall and then attach the
mounting brackets to the plywood.
3. When using the supplied mounting bracket, it creates a 5/8" clearance from
the back of the unit.
4. The upper bracket is installed on the wall and the water heater is then hung on
the bracket. On the back of the water heater at each of the top corners, there is
a hanger bracket on the back of the water heater that interlocks with a tab on
the wall mounting bracket;
