CYLINDER GAS SUPPLY
WARNING: Review and understand
the warnings in the Safety Information
2. They are needed to safely operate
this heater. Follow all local codes
when using this heater.
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.
WARNING: Use pipe joint sealant
that is resistant to liquid petroleum
(PL) gas. Never bring a refillable
propane/PL cylinder indoors. A fire or
explosion can occur causing property
damage, serious injury or death.
WARNING: This appliance requires a
3/8 in. NPT (National Pipe Thread) inlet
connection to the pressure regulator.
WARNING: A qualified service
technician must connect heater to gas
supply. Follow all local codes.
IMPORTANT: You must use a propane/
PL gas supply cylinder that is compatible
with the connection device provided with
the hose and regulator.
1. Remove gas fitting from
hardware bag.
2. Apply pipe joint sealant lightly to
male NPT threads (see Figure
13-A). 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/PL supply
system (see Propane/PL
Supply, page 3).
5. Connect fuel gas fitting on
hose/regulator assembly to
propane/PL tank(s). Turn fuel
gas fitting counterclockwise
into threads on tank.

6. Connect hose to heater inlet.
Tighten firmly using a wrench.
You must use the regulator
supplied with heater.
7. Open propane/PL supply valve
on propane/PL tank(s) slowly.
Note: If not opened slowly,
excess-flow check valve on
propane/PL tank may stop gas
flow. If this happens, close
propane/PL supply valve and
open again slowly.
8. Check all connections for leaks.
Apply a noncor rosive leak
detection fluid to gas joints.
Bubbles forming indicate a leak
that must be corrected.
9. Close propane/PL supply valve
