REFILLING THE PROPANE GAS TANK
Propane is safe to use when properly handled. Careless handling of the Propane gas tank could result in
fire and/or an explosion. Therefore:
• Always keep tank/cylinder securely fastened in an upright position.
• Avoid tipping tank on its side when connected to a regulator since this may cause damage to
diaphragm in regulator.
• Handle valves with care.
• Never connect an unregulated Propane tank to construction heater.
• Do not subject Propane tank to excessive heat.
• Tightly close the gas shutoff valve on the Propane tank after each use.
• The POL fitting must be protected when disconnected from the propane tank.
• Never store a Propane gas tank inside a building or in the vicinity of any gas burning appliance.
THE DISCONNECTED TANK MUST NEVER BE STORED IN A BUILDING,
GARAGE OR ANY OTHER ENCLOSED AREA.
ALL NEW CYLINDERS MUST BE PURGED BEFORE THE FIRST FILLING.
• Turn heater gas valve knob and gas tank valve to OFF position.
• Propane tank valve equipped with the old style fitting has LEFT HANDED THREADS. Turn POL fitting
CLOCKWISE to loosen. Protect POL fitting when disconnected from tank.
• Have tank filled by your local Propane gas supplier.
• Some propane tanks have a bleed-off valve. This valve should be inspected for leaks after each filling of
the tank. Turn clockwise to close the valve.
• Fasten full Propane tank and connect POL fitting to tank valve by turning COUNTERCLOCKWISE.
• With heater gas valve knob still in the OFF position, turn ON tank valve and check for leaks with soap solution.
The propane (LP) gas pressure regulator and hose assembly of 30K BTU models supplied with
