Lp Tank Filling Practices; Lp Gas Regulator - Tiffin Motorhomes 2015 Allegro Owner's Manual

If a gas leak is noted or suspected, turn "off" the main valve and keep the LP
gas system "off" until that system is inspected by a qualified service techni-
cian as soon as possible. Do not delay in addressing any possible gas leaks
with appropriate service because of the inherent hazards to safety.

LP TANK FILLING PRACTICES

Any LP gas tank associated with the motorhome should never be filled to more than 80 percent of total
capacity. Filling should always be done only when the motorhome is leveled. If the motorhome is not
level, the tank may be overfilled (i.e., more than 80 percent of capacity) and, thus, subject the motor-
home to possible fire or explosion from resultant uncontrolled gas flows.

LP GAS REGULATOR

As noted earlier, the LP gas regulator (Figure
4-2) is the "heart" of the LP gas distribution
system. This regulator reduces and controls
the pressure of the gas on the outlet end to
provide a constant supply of gas at a constant
pressure to the gas-operated appliances. The
regulator has a vent to relieve excess pressure
on the inlet side of the regulator, should excess
pressure develop in the gas tank and connect-
ing gas line to that regulator inlet. The vent
would normally release the excess LP gas to
the atmosphere until the over-pressurization
condition is eliminated.
This vent should be regularly checked to assure
that it is not clogged or obstructed. If that vent
is blocked from normal operation, component or system failures may result. If periodic visual inspec-
tion indicates any sign of corrosion or degradation, contact a qualified service technician to repair the
regulator as soon as possible; DO NOT operate the LP gas system with any faulty component in place.
