The garlic-like smell of LP gas indicates a leak. Fittings,
valves and couplings'
~re
the most common places for a gas
system to leak.
For your safety, check for leaks in your gas system each time
the tank is filled and before each trip. Always check the sys-
tem any time you detect a garlic-like odor. Listen for a hiss
or hum when you turn the gas on. This may indicate a leak.
The first time you have your LP tank filled, have the atten-
dant bleed a little LP gas out of the small outage valvt; (this
also lets you check that the tank is not overfilled) and note
the odor. It should smell like garlic or onions. If you cannot
detect this odor, you must take extra care in checking for
leaks, as well as whenever you use LP gas appliances.
To perform a leak check:
1. Swab a mixture o( an approved leak detection solution over
each fitting, joint and connection in the system.
2. Open the tank valve.
3.lnspect each joint.
.4. If even the smallest bubbles appear at any joint, it is leaking
and must be corrected. Take the motor home to an autho-
rized Fleetwood service center or your LP gas service facili-
ty. Do not attempt to repair gas piping unless you have the
proper tools and skill.
Leaks most likely will occur where piping runs close to chas-
sis and frame. Look for scrapes and cracks around pipe
hangers. If you find defects in any part of the LP gas system,
have it repaired or replaced before using the system.
