Connecting Propane Regu-
lator to Propane Gas Supply
1. At the inlet of the regulator is a male nut and stem
called a POL. Remove the cap from the POL but do not
discard it. Insert POL stem into the valve on the propane
fuel container. Thread the nut counterclockwise into the
container’s valve. Tighten the nut securely with a wrench.
See Fig. 7.
2. Slowly open the tank or cylinder valve. This will prevent
lock-up of the excess fl ow valve within POL stem.
3. Check all connections with approved leak detector. Do not
use fl ame to check for leaks. A fi re or explosion may result.
4. When storing or transporting the heater, ensure the cap is
pushed back onto the POL fi tting to protect the fi tting from
damage and prevent entry of dirt.
