Figure 10 - Removing Front Panel Of
Installing Bottom Mounting Screw
1. Locate bottom mounting hole. This hole is
near bottom on back panel of heater (see
Figure 11).
2. Mark screw location on wall.
3. Remove heater from wall.
4. If installing bottom mounting screw into hol-
low or solid wall, install wall anchor. Follow
steps 1 through 5 under Attaching To Wall
Anchor Method, page 9. If installing bottom
mounting screw into wall stud, drill hole at
marked location using 9/64" drill bit.
5. Replace heater on wall.
6. Insert bottom anchor screw through back
panel into bottom anchor or drilled hole
(see Figure 11).
7. Tighten screw until heater is firmly se-
cured to wall. Do not over tighten.

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 3/8" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified service
person must connect heater to gas
supply. Follow all local codes.
WARNING: For natural
gas, never connect heater to
private (non-utility) gas wells.
This gas is commonly known
as wellhead gas.
IMPORTANT: For natural gas, check gas line
pressure before connecting heater to gas line.
Gas line pressure must be no greater than
10.5" of water. If gas line pressure is higher,
heater regulator damage could occur.
CAUTION: For propane/LP
gas, never connect heater di-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between the
heater and propane/LP supply.
For propane/LP gas, the installer must supply
an external regulator. The external regulator
will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11"
and 14" of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
12, page 11. Pointing the vent down protects
it from freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
large enough diameter to allow
proper gas volume to heater. If
pipe is too small, undue loss of
volume will occur.
