Methods For Attaching
Mounting Bracket To Wall
Only use last hole on each end of mounting
bracket to attach bracket to wall. Attach
mounting bracket to wall in one of two ways
1. Attaching to wall stud
2. Attaching to wall anchor
Attaching to wall stud: This method pro-
vides 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.
Figure 7 - Mounting Bracket Clearances
WARNING: Maintain minimum
clearances shown in Figure 7. If
you can, provide greater clear-
ances from floor and joining wall.
2. Mark screw locations on wall (see Fig-
ure 7).
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.
Attaching Mounting Bracket To
Wall
Note: Wall anchors, mounting screws, and
spacers are in hardware package. The hard-
ware package is provided with heater.
Attaching to Wall Stud Method
For attaching mounting bracket to wall studs
1. Drill holes at marked locations using
9/64" drill bit.
2. Place mounting bracket onto wall. Line
up last hole on each end of bracket with
holes drilled in wall.
3. Insert mounting screws through bracket
and into wall studs.
4. Tighten screws until mounting bracket
is firmly fastened to wall studs.
Attaching to Wall Anchor Method
For attaching mounting bracket to hollow
walls (wall areas between studs) or solid
walls (concrete or masonry)
1. Drill holes at marked locations using
5/16" drill bit. For solid walls (concrete
or masonry), drill at least 1" deep.
2. Fold wall anchor as shown in Figure 8.
3. Insert wall anchor (wings first) into
hole. Tap anchor flush to wall.
4. For thin walls (1/2" or less), insert red
key into wall anchor. Push red key to
“pop” open anchor wings (see Figure
9).
IMPORTANT: Do not hammer key!
For thick walls (over 1/2" thick) or solid
walls, do not pop open wings.
5. Place mounting bracket onto wall. Line
up last hole on each end of bracket with
wall anchors.
6. Insert mounting screws through bracket
and into wall anchors.
7. Tighten screws until mounting bracket
is firmly fastened to wall.

Installing Bottom Mounting
Screws
1. Locate bottom mounting hole. This
hole is near the bottom on the back
panel of heater (see Figure 11).
2. Mark screw location on wall.
3. Remove heater from mounting bracket.
4. If installing bottom mounting screw
into hollow or solid wall, install wall
anchor. Follow steps 1 through 4 un-
der Attaching To Wall Anchor Method.
If installing bottom mounting screw
into wall stud, drill hole at marked lo-
cation using 9/64" drill bit.
5. Replace heater onto mounting bracket.
6. Place spacer between bottom mount-
ing hole and wall anchor or drilled hole.
7. Hold spacer in place with one hand.
With other hand, insert mounting screw
through bottom mounting hole and
spacer. Place tip of screw in opening
of wall anchor or drilled hole.
8. Tighten screw until heater is firmly se-
