Propane Regulator - Nucamp T@B 320 Manual

normal flow to the system. Equalization occurs in
approximately 5 seconds and, in most cases, goes
completely unnoticed. If, however, an appliance is
left on or there is a leak or open flow in the system,
the bypass pressure will not be able to equalize and
allow the flow-limiting device to reopen. Symptoms
of this condition would be appliances that light but
have lower than normal flame or starve out from
lack of gas, a substantial reduction in the flame
when another appliance is operating, or pilots that
are difficult to light. If this should happen, the
following steps should eliminate the condition:
1. Close LPG cylinder valve.
2. Extinguish all flames and smoking materials.
3. Be sure all gas appliances, including their pilot
lights, are off.
4. Open LPG cylinder valve slowly. Do not snap
open.
5. Wait at least 15 seconds before lighting
appliances.
6. If operational difficulties continue, there may be
a leak in the system. Immediately close the LPG
cylinder valve and have the system inspected by a
qualified RV service technician.
WARNING
Leaking LPG may ignite, causing a fire or
explosion, which could result in serious bodily
injury, property damage, and/or death.
How long a full tank of gas will last is dependent on
usage. when you are doing extensive cooking, you
will naturally use more gas than you will on the
average, with normal cooking

Propane Regulator

Propane is under high pressure in the tank. The
purpose of the regulator is to reduce the pressure
inside the tank to allow for safe use.
WARNING

To avoid potential problems, have your
propane system checked at least once a year
by an authorized service center after each
extended trip.

NEVER test for a leak by lighting a match
or having an open flame where you suspect
a leak. Take your recreational vehicle to an
authorized service center.
Regulator Freeze-Up
The term 'regulator freeze-up' is a misleading one.
Regulators and propane do not freeze. However, the
moisture that can be contained in the propane will
freeze as the propane expands and cools passing
through the regulator. This freezing of the moisture
in the propane can build up and partially or totally
block the passage of the propane through the
regulator. Freezing can also occur when outside
temperatures are low enough to contribute to the
freezing of the moisture in the propane. The source
of the moisture is varied. It can occur at the refinery
or propane bulk plant, in the cars used to transport
the propane, or even within your own propane
tanks. Moisture in a propane tank can occur when a
tank service valve is left open, allowing moist air to
enter and become trapped. A two-stage regulator
helps reduce the possibility of freeze-up because of
its larger orifice size and that heat is being
transferred through the walls of two regulators
instead of only one.
NOTE: If freeze-up does occur, shut the propane
off at the tank. A frozen regulator may permit
propane to flow at high pressure, resulting in leaks
at appliances or in the lines. Never attempt to thaw
with an open flame. A small light bulb can
sometimes be useful to provide heat and aid the
thawing process. Once thawed, be sure to take the
proper steps to prevent a reoccurrence. Have the
system checked by your propane supplier.
