IDENTIFICATION & SAFETY
How to Test
Never use an open flame of any kind to test this unit. The built-in test switch accurately
tests the unit’s operation as required by Underwriters Laboratories, Inc. (UL).
Simply press the TEST switch any time during the warm-up cycle or while in normal
operation. The LED should flash red and the alarm should sound. Release the switch. This is
the only way you should test your detector. The test feature checks the full operation of the
detector. If this detector does not test properly return it immediately for repair or replacement.
TEST: This test procedure should be repeated every week or every time the motorhome is
taken on a trip, whichever occurs first.
REFERENCE: Refer to the manufacturer’s Owner’s Manual or all the detector manufacturer,
if you have any questions about the LP Gas Detector.
Checking the LP Gas System for Leaks
Never check for leaks with an open flame. The scent of LP Gas (a garlic-like odor) is
actually ethyl mercaptan, an additive that allows you to detect the presence of a leak,
since LP Gas is naturally odorless. Do not rely upon being able to detect the smell of the
gas, as the odor may fade.
Road vibration can loosen LP Gas fittings. It is important to check the LP system for leaks at
least every 5,000 miles, and whenever the tank is filled. It is also a good idea to have the entire
LP Gas system checked annually by a qualified LP Gas service representative.
Use the following steps when checking the system for leaks:
3-10
1. Open all the windows and vents.
2. Open the gas tank service valve.
3. Use non-ammoniate, non-chlorinated soap solution, or an approved leak detection
solution on all line connections (ammoniate soap solutions can cause cracking on
copper or brass lines and fittings).
4. If a leak is detected, tighten the connection with two open end wrenches until
bubbling stops. DO NOT over tighten, or use excessive force. If the leak continues,
contact the recreation vehicle dealer, or a qualified LP Gas service representative to
have an 11" Water Column Test performed.
