1. Remove gas fitting from hardware bag.
2. Apply pipe joint sealant lightly to male
NPT threads (see Figure 13). 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 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 7).
5. Connect fuel gas fitting on hose/regulator
assembly to propane/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 horizon-
tal position (see Figure 14). 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.
7. Open propane/LP supply valve on pro-
pane/LP tank(s) slowly.
Note: If not opened slowly, excess-flow
check valve on propane/LP tank may stop
gas flow. If this happens, close propane/
LP supply valve and open again slowly.
CONNECTING TO PERMANENTLY LOCATED GAS SUPPLY
WARNING: A qualified ser-
vice technician must connect
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.
WARNING: Do not over-
tighten gas connections.

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
1/2" diameter or greater to allow
proper gas volume to heater. If
pipe is too small, undue loss of
pressure will occur.
