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.

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 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.
