Attaching to Wall Stud
This way is the best providing the
strongest mounting in wood frame
houses.
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 holes on each end of bracket
with hole 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
This way allows you to attach
mounting bracket to hollow walls (wall
areas between studs) or to solid walls
(concrete or masonry).
1. Tape mounting bracket to wall where
heater will be located. Make sure
mounting bracket is level. For wall
stud mounting locate one end of the
mounting bracket over a wall stud.
2. Mark screw locations on wall.
See figure 7.
3. Remove tape and mount bracket to
wall.
Note:
Wall anchors, mounting screws,
and spacer are in hardware package.
The hardware package is provided with
heater.
4. Drill holes at marked locations using
5/16” drill bit. For solid walls (concrete
or masonry), drill at least 1” deep.
5. Fold wall anchor as shown in Figure 8
below.
6. Insert wall anchor (wings first) into
hole. Tap anchor flush to wall.
7. For thin walls (1/2” or less) insert red
key into wall anchor.
8. Place mounting bracket onto wall.
Line up holes on each end of bracket
with wall anchors.
9. Insert mounting screws through
bracket and into wall anchors.
10. Tighten screws until mounting bracket
is firmly fastened to wall.
Placing Heater on Mounting Bracket
1. Locate two horizontal slots on back
pane of heater. See Figure 9.
WARNING:
Maintain minimum
clearances shown in Figure 7. If you
can, provide greater clearances from
the floor and joining wall.

2. Place heater onto mounting bracket.
Slide horizontal slots onto stand-out
tabs on mounting bracket.
Installing Bottom Mounting Screws
1. Locate two bottom mounting holes.
These holes are near bottom on back
panel of heater. See Figure 10.
2. Mark screws locations on wall.
3. Remove heater from mounting
bracket.
4. If installing bottom mounting screw
into hollow or solid wall, install wall
anchors. Follow steps 1 through 4
under Attaching to Wall using Anchor.
If installing bottom mounting screw
into wall stud, drill holes at marked
locations using 9/64” drill bit.
5. Re-place heater onto mounting
bracket.
6. Place spacers between bottom
mounting holes and wall anchor or
drilled hole.
7. Hold spacer in place with one hand.
With the 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 both screws until heater is
firmly secured to wall. Do not over
tighten.
Note:
Do not re-place front panel at
this time.
9. Replace front panel after making gas
connections and checking for leaks.
Floor Mounting Away From Wall
Installing Support Feet (See Figure 11):
1. Lay heater onto table on its back with
bottom edge overhanging table edge.
2. Securely attach feet to bottom of
heater using 2 – self-tapping screws
each.
Note:
Feet should have long end going
out the front of heater, and the edge
coinciding with side of heater. If feet
overhang side of the heater, switch leg
location.
3. Place heater on non-combustible
surface (see Locating Heater, page
6) before proceeding with gas
connection. If this will be a permanent
location, heater may be locked into
position using anchoring holes in
mounting feet.
Note:
Use of floor mounting feet will
require you to use a 3/8 NPT street
elbow to make gas connection.
