the motorhome is in between trips.
• Hand tighten the manual valve. Do not use a wrench or
pliers to close the valve.
• The manual valve is designed to be closed by hand, over
tightening may permanently damage the valve seat.
The regulator is the heart of an LP-Gas system.
The LP-Gas in the tank is under high pressure. The
regulator reduces the pressure of gas so that it is
safe to use with various appliances. The regulator
on the motorhome is a two-stage regulator. Simply
put, the first stage regulator reduces the full tank
pressure down to a range of 10-13 psi. The second
stage further reduces the pressure down to an outlet
pressure of 0.4 psi (11 inches of column water). The
regulator is equipped with a vent so that it can
breathe. This means that if pressure in the LP tank
is too high the regulator will allow gas to escape
through the vent until pressure returns to a normal
range. It is important to keep the vent clean and
clear of obstructions or corrosion. If the vent
becomes clogged, pressure from LP tank could
cause a failure of the components. If you notice any
corrosion contact a qualified LP-Gas service techni-
cian. The regulator is mounted so that the vent faces
downward. If the vent becomes clogged you can
clean it with a toothbrush.
Under normal atmospheric conditions a LP regu-
lator will not freeze, nor will the LP-Gas. The gas
passing through the regulator will expand and cool
creating moisture in the gas. This moisture will turn
to ice which can build up and partially or totally
block the orifice. The possibilities of freeze up is
greatly reduced with the two stage regulator.
Things you can do to prevent this freeze up are:
1. Ensure the LP tank is totally free of moisture prior to filling.
2. Ensure the tank is not overfilled.
3. Keep the valve closed when the tank is empty.
4. A LP-Gas dealer will need to purge the tank if freeze up occurs.
5. Have the LP-Gas dealer inject methyl alcohol in the tank.
