Regulator
Propane regulators must always be installed with the regulator vent
facing downward. Regulators that are not in compartments have
been equipped with a protective cover. Make sure that the
regulator vent faces downward and that the cover is kept in place
to minimize vent blockage that could result in regulator not being
able to breath and to operate.
The regulator has the only moving components in the propane
system. It’s sole function is to reduce the high and varied pressure
from the propane containers to safe and consistent low operating
pressure. The small inlet is the first stage, which reduces the
container pressure to 10-13 pounds.
The second stage then reduces the 10-13 pound pressure to an
operating pressure of 11 inches w.c. (water column) or 6.35
ounces of outlet pressure to your appliances. The second stage is
adjustable and may need to be adjusted for precise operation. We
suggest this to be normal maintenance and performed once per
year. Do not attempt to make this adjustment without a
manometer or a u-tube gauge. This instrument is required to read
actual pressure.
If pressure is too high, it affects performance and safety. Should
pressure be too low, appliances will not operate correctly. An
authorized technician with proper equipment should perform such
tests and adjustments, as may be required.
The main type of regulator used is the “automatic” two stage
regulator, used on larger coaches (optional on smaller coaches).
With both cylinders full of propane, turn the lever on the regulator
towards the cylinder you wish to use first. This will now be the
“supply” cylinder and the other “reserve”. Slowly open both
cylinder valves.
