Installing Bottom Mounting Screw
1. Locate bottom mounting hole. This hole is near bottom on back
panel of heater (see Figure 9).
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 5. 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 9).
7. Tighten screw until heater is firmly secured 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 9 and 10).
WARNING: Review and understand the warnings
in the
Safety Information
section, page 2. They are
needed to safely operate this heater. Follow all local
codes when using this heater.
IMPORTANT: You must use a propane/LP gas supply cylinder that
is compatible with the connection device provided with the hose and
regulator.
WARNING: Test all gas piping and connections
for leaks after installation or servicing. Never use an
open flame to check for a leak. Apply a noncorrosive
leak detection fluid to all joints. Bubbles forming
show a leak. Correct all leaks at once.
CONNECTING TO PORTABLE CYLINDER
GAS SUPPLY
Figure 9 - Installing Bottom Mounting Screw
1. Remove 90° gas fitting from hardware bag.
2. Apply pipe joint sealant lightly to male NPT threads (see Fig-
ure 10). This will prevent excess sealant from going into pipe.
Excess sealant in pipe could result in clogged heater valves.
3. Hold gas pressure regulator with wrench when connecting the
90° gas fitting. Do not over tighten connection to regulator.
The regulator body could be damaged.
4. Provide propane/LP supply system (see Propane/LP Supply,
page 4).
5. Connect fuel gas fitting on hose/regulator assembly to pro-
pane/LP tank(s). Turn fuel gas fitting counterclockwise into
threads on tank. Tighten firmly using a wrench.
IMPORTANT:
Position regulator so that hose leaving the regulator is in a
horizontal position (see Figure 11). This places the regulator
vent in the proper position to protect it from the weather.
6. Connect hose to heater inlet. Tighten firmly using a wrench.
You must use the regulator supplied with heater.
Apply Sealant To
This End Only
WARNING: Use pipe joint sealant that is resistant
to liquid petroleum (LP) gas.
