REGULATOR
Propane regulators must always be installed with the vent facing
downward. Regulators that are not in compartments have been
equipped with a protective cover. Should vent be covered, the regu-
lator cannot operate.
The regulator has the only moving components in the propane sys-
tem. It’s sole function is to reduce the high and varied pressure from
the propane containers to safe and consistent low operating pres-
sure. 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 op-
erating pressure of 11 inches WC. (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. It is suggested
this to be normal maintenance and performed once per year. Do not
make this adjustment without a manometer. This instrument is re-
quired 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 au-
thorized and competent technician with proper equipment should
perform such tests and adjustments, as may be required.
Two types of propane regulators are used on KZ products. First, is
the standard two stage regulator with a brass T-check connector to
mount two propane bottles. It is suggested opening only one bottle
at a time. Should you open both bottles, they will draw vapor to-
gether, resulting in both tanks becoming empty at the same time.
This standard regulator is used on smaller coaches.
The second type is the “automatic” two stage regulator used on lar-
