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.

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.
Hose Replacement
The flexible LP gas hoses connected to your LP tank
should be checked regularly for signs of deterioration
and may need to be replaced every two to three years.
Be sure to replace the hoses with approved and
properly rated products.
Regulator Vent Maintenance
Since the LP gas regulator is equipped with a vent
that allows the system to “breathe,” you must check it
on a routine basis to see that it does not become
clogged. If dirt, sealant or corrosion clogs the vent,
clean it with a toothbrush or similar device. At least
once a year have your LP serviceman check the
regulator for adjustment and operation.
