Propane Vaporization In Cold Weather - Winnebago Via 25Q Manual

WARNING
Visually inspect the pressure regulator
vent periodically for blockage by
accumulated debris or insect nests, etc.
Vent obstruction could result in excessive
pressure causing fire or explosion, which
could result in death or serious injury. If an
obstruction exists, have the regulator
serviced by a qualified service center.

Regulator Freeze-up
Regulator freeze-ups are caused by the
presence of moisture in fuel. This moisture will
pass through the cylinder valve and into the
regulator where it can freeze. Fuel producers,
tank and bottle manufacturers, and propane gas
dealers take every precaution to reduce moisture,
but sometimes only a fraction of an ounce
entering the tank can cause problems. To help
avoid the possibility of freeze-up, always keep
tank control valve closed when not in use, even
when tank is empty, to prevent moisture from
collecting on the inside.
If regulator freeze-up should occur, you may
attempt to thaw the regulator using a light bulb.
DO NOT USE AN OPEN FLAME OR HEAT
LAMP.
If moisture begins to cause problems, have
your propane gas dealer inject a small amount of
dry methyl alcohol in your tank (approximately
one ounce to 20 pounds or one pint to 100
gallons) to help guard against regulator freeze-
ups.
PROPANE VAPORIZATION IN
COLD WEATHER
Propane gas vaporization increases and
decreases in direct relation to ambient
temperature. In other words, the lower the
temperature, the slower the liquid propane will
vaporize into a usable gas for appliances.
