Lp Gas Regulator; Lp Distribution System - Tiffin Motorhomes 2014 Allegro Owner's Manual

TIFFIN MOTORHOMES
Generally, loose fittings can be tightened (with "non-sparking" tools) to stop the leaks. If this process doesn't
work, then one must shut off the main gas valve at the LP cylinder(s) and immediately consult an authorized
service technician to determine what repairs are necessary. Leaks may also be detected by noting the sulfurous odor
(i.e., rotten eggs) associated with LP gas [caused by an additive added to the normally odorless LP gas].
DO NOT search for a leak by using a match or open flame.
When the motor home is not in use, be sure to close the main LP gas valve at the
tank. When the LP gas tank is to be refilled, close the main valve to preclude the
chance of the pilot lights possibly igniting fumes from the LP fuel. As some LP-gas
appliances (e.g., refrigerator, furnace, water heater) have Direct Spark Ignition (DSI)
systems, it is very important that these appliances be turned "off" when the LP gas
is "off." The DSI boards will continue to work (i.e., generate an ignition spark) even

LP Gas Regulator

The LP gas regulator (Figure 2-4, center of picture) is the most critical element of the LP-gas distribution system.
The regulator converts the high-pressure LP gas from the tank into a reduced-pressure LP-gas supply suitable for use
in the various appliances in the motor home. One should regularly inspect visually the regulator system. If any
damage or corrosion is noted, contact an authorized service technician to inspect and repair or replace
the regulator. Do not attempt to adjust the regulator yourself; the regulator has been pre-set at the factory.
Only a qualified LP service technician using specialized equipment should adjust the regulator.

LP Distribution System

The primary LP distribution system in the motor home is a black, steel pipe manifold running the length of the
motor home. The secondary distribution lines running from this main distribution system are usually copper
tubing with flare fittings. If any of the gas lines break, do not attempt to splice them—always run new lines to
maintain the safety of the motor home. It is strongly recommended that only qualified service technicians
perform this work. Remember, the main valve at the LP gas tank must be closed whenever any gas appliance is to be
installed, removed, or serviced—this process prevents LP gas leakage which could result in a possible harmful
explosion. If the odor of LP gas (e.g., rotten eggs) is ever detected, immediately discontinue use of any gas
appliances and seek the services of a qualified service technician.
