Screws
Removing Front Panel Of Heater
1. Remove two screws near bottom corners
of front panel.
2. Lift straight up on grill guard until it stops.
Grill guard will slide up about 1/4".
3. Pull bottom of front panel forward, then
down.
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
hollow or solid wall, install wall anchor.
Follow steps 1 through 5 under
Attaching
To Wall Anchor Method
, page 9. If install
-
ing 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.
Note: Do not replace front panel at this
time. Replace front panel after making
gas connections and checking for leaks
(see pages 10 through 13).
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" W.C.. 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"
W.C.. If you do not reduce incoming gas pres
-
sure, heater regulator damage could occur. Install
the 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. Internally-tinned
copper tubing may be used in
certain areas. Check your local
codes. Use pipe of large enough
diameter to allow proper gas vol-
ume to heater. If pipe is too small,
undue loss of volume will occur.
