to check for leaks. Apply a 50/50
mix ture of dish soap and water to
all connections. Bubbles forming are
evidence of a leak. Be sure to correct
all leaks at once!
1. Provide propane supply system as
outlined above.
2. Connect POL fitting on hose/regulator
assembly to propane tank(s) by turn ing
the fitting COUNTER CLOCKWISE
into the threads on the valve on top of
the tank. Finish by tightening firmly,
using 7/8” (22.2 mm) wrench.

To protect the regulator
from weather damage, tighten the
fitting with the black adjustment knob
pointing down.
3. Connect female end of hose to the
inlet connector of the heater, and

Use extra piping or hose
if necessary to connect the heater to the
gas supply, but always use the regulator

4. Open supply valve on propane tank(s)
SLOWLY.
NOTE:
If this valve is not opened slowly,
the excess flow check valve on the
tank will interrupt the gas flow. If this
happens, close the supply valve and
reopen slowly.
5. Adjust the regulator to between 7
and 10 PSIG.
Do not adjust the
regulator above 10
PSIG or below 7 PSIG, or the heater may
not operate properly.
6. Check all connections for leaks.
Never use an open
flame to check for
leaks. Apply a 50/50 solution of liquid
dish soap and water to check all
connections. Correct all leaks

of fresh, outside air for each 100,000 BTU/
Hr of rating. This heater requires
a fresh air opening of at least 11.25 square
feet (1.05 m²). Provide extra fresh air if
more heaters are being used.
