Liquid Propane (Lp) Gas System - Tiffin Motorhomes Allegro Bus 2011 Owner's Manual

Liquid propane (LP) gas containers, gasoline, or other
flammable liquids are not to be placed or stored inside the
motor home because a fire or explosion may occur. LP
gas containers are equipped with safety valves that may
relieve excess pressure by discharging gas into the
atmosphere—any containment of that vented LP gas
• NEVER use an open flame to test for LP gas leaks or to examine the fluid levels in the fuel tanks.
• After filling any LP system, immediately replace and secure all protective covers and caps.
• After closing the LP valve, close and securely latch the LP door to prevent unintentional access or
damage.
• NEVER connect natural gas to the LP gas system—LP gas and natural gas are not interchangeable.
• NEVER use any other "burning" equipment (e.g., charcoal grills, wood stoves, butane lights, propane
lights) inside the motor home—doing so may cause fires and/or asphyxiation.

Liquid Propane (LP) Gas System

A warning label is conspicuously located near the LP gas container (Figure 2-4); that label reads:
DO NOT FILL the LP Container(s) to more than 80% of capacity.
Any overfilling of the LP gas container(s) can result in uncontrolled gas
flow—a prime condition for a fire or explosion. The LP container should
only be filled to 80% of its capacity; the remainder of the cylinder space is
vapor space to contain expansion of that liquid when subjected to varying
ambient-temperature conditions. Filling in excess of 80% of the liquid
volume of the container reduces that vapor space and, thus, creates a
condition for possible over-pressurization of the container.
