IMPORTANT: Vent-free
heaters add moisture to the
air. Although this is beneficial,
installing heater in rooms
without enough ventilation air
may cause mildew to form
from too much moisture. See
Fresh Air for Combustion and
Ventilation, pages 4 and 5.
FASTENING HEATER TO WALL

The mounting bracket is located
on back panel of heater (see
figure 6). It has been taped there
for shipping. Remove mounting
bracket from back panel.
Removing Lower Front Panel Of
Heater.
1. Remove two screws near
bottom corners of front panel.
2. Pull bottom of lower front panel
forward, then down (see Figure

Methods For Attaching Mounting
Bracket To Wall
Only use last hole on each end
of mounting bracket to attach
bracket to wall. These two holes
are 16 inches apart from their
centers. Attach mounting
bracket to wall only in one of two
ways:
1. Attaching to wall stud
2. Attaching to wall anchor
Attaching to Wall Stud: This
method provides the strongest
hold. Insert mounting screws
through mounting bracket and
into wall studs.
Attaching to Wall Anchor: This
method allows you to attach
mounting bracket to hollow walls
(wall areas between studs) or to
solid walls (concrete or masonry).
Decide which method better
suits your needs. Either method
will provide a secure hold for the
mounting bracket.
Marking Screw Locations
1. Tape mounting bracket to wall
where heater will be located.
Make sure mounting bracket is
level.
2. Mark screw locations on
wall. (see Figure 8)
Note: Only mark last hole on
each end of mounting bracket.
Insert mounting screws through
these holes only.
3. Remove tape and mounting
bracket from wall.
WARNING: Maintain
minimum clearances shown in
Figure 8. If you can, provide
greater clearances from floor
and joining wall.
