FILLING THE LP TANK
Make sure that all burners and pilot lights are turned OFF prior to having a gas supplier refill your LP tank.
Drive your unit to the LP supplier for filling. Never remove the tank from the unit. The supplier will connect his fill
nozzle to your unit’s LP tank FILL VALVE.
When the tank is being filled, the service valve must be CLOSED. The 20 percent LIQUID LEVEL GAUGE must be
OPEN.
The 80 percent STOP FILL VALVE may close the valve before liquid appears at the 20 percent liquid level gauge,
but if liquid does appear, stop filling immediately…the tank is filled to its LP capacity.
Do not use a wrench to tighten the service valve or the 20 percent gauge. They are both designed to be closed leak-
tight by hand. If you cannot hand-tighten the valve, the valve may need repair or replacement. Consult your gas
dealer.
YOUR LP TANK MUST BE KEPT FREE OF RUST AT ALL TIMES. IF RUST DOES DEVELOP, THE TANK
SHOULD BE CLEANED COMPLETELY FREE OF THE RUST, PRIMED, AND PAINTED WHITE (OR SOME OTHER
HIGHLY REFLECTIVE COLOR) WHICH WILL HELP TO REDUCE EXPANSION OF THE LP GAS BECAUSE OF
HEAT.
GAS LINE CHECK
Check the gas line connection and all other connections
regularly. To check, turn OFF all burners and pilot lights.
Open all doors and windows. OPEN the LP gas tank
service valve and use soapy water or an approved leak
detector fluid to test all line connections. Do not use
products that contain AMMONIA or CHLORINE. The
appearance of bubbles in the soapy solution indicates
a leak. Tighten the connections with two (2) open-end
wrenches until the bubbles stop. If this does not take
care of the leak, contact your gas dealer.
DO NOT OVERTIGHTEN. (FIG. 12)

REGULATOR PRESSURE
Have the gas regulator checked at the beginning of each season and whenever a problem occurs. Proper line
pressure is 11 inches of water column. Your RV dealer or gas supplier can perform this needed check.
GAS TANK AND REGULATOR FREEZE-UP
LP gas regulator freeze-up can be prevented if owners are aware of its causes. Freeze-up may be caused by one of
these things: moisture in the tank, an overfilled tank or a greater vapor withdrawal demand than the tank can deliver at
a particular temperature.
Freeze-up occurs more frequently in cold weather since liquid gas does not vaporize as quickly. This, along with a
higher demand, can cause frosting of the tank and regulator. Be sure to have your LP gas supplier add ANHYDROUS
METHANOL before filling the tank in cold weather.
Moisture may enter the tank in the LP gas through condensation if air is allowed to enter the tank through an open
valve. This can be avoided by using moisture-free gas and keeping all tank valves CLOSED during storage. If
moisture is present, have the tank purged by an authorized dealer and have him add the proper amount of
ANHYDROUS METHANOL for your tank.
An overfilled tank can allow liquid gas, rather than the needed vapor, to flow through the regulator. This can result in
erratic regulator delivery pressure, improper appliance operation and possible frosting of the regulator and gas line.
This can be avoided by following the procedures outlined in “Filling the LP Tank.” Always contact your local gas
supplier for current procedures.
