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 se-
cured to wall. Do not over tighten.
Note: Do not re-place front panel at this time. Re-
place 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.
Figure 11
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 us-
ing 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 connec-
tion.
CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-
nect heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8” NPT
(National Pipe Thread) inlet connection to the
pressure regulator. Use of floor mounting feet will
require you to use a 3/8 NPT street elbow to make
gas connection.
CAUTION: Never connect heater directly to the
Propane supply. This heater requires an external
regulator (not supplied). Install the external regulator
between the heater and Propane/LP supply.
The installer must supply an external regulator.
The external regulator will reduce the incoming gas
pressure to between 11 and 14 inches of water. If
you do not reduce incoming gas pressure heater
regulator damage could occur. Install external regu-
lator with the vent pointing down. Pointing the vent
down protects it from freezing rain or sleet.
CAUTION: Use only new black iron or steel pipe.
Internally-tinned copper tubing may be used in cer-
tain areas. Check your local codes. Use pipe of larger
enough diameter to allow proper gas volume to heater.
If pipe is too small, undue loss of pressure will occur.
Installation must include an equipment shutoff valve,
union and plugged 1/8” NPT tap. Locate NPT tap within
reach of test gauge hookup. NPT tap must be upstream
from heater (see figure 12).
*A CSA/AGA certified equipment shutoff valve with
1/8” NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certified equipment
shutoff valve from your dealer.
IMPORTANT: Install an equipment shutoff valve in an
accessible location. The equipment shutoff valve is for
turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess
sealant in pipe could result in clogged heater fuel train.
CAUTION: Use pipe joint sealant that is resistant to
LP-Gas.
Install sediment trap in supply line as shown in figure
12. Locate sediment trap where it is within reach for
cleaning. A sediment trap traps moisture and con-
taminants. This keeps them from going into heater. If
sediment trap is not installed or is installed improperly,
heater may not run correctly.
IMPORTANT: Hold pressure regulator with wrench
when connecting it to gas piping and/or fittings.
