caution - Thor Motor Coach

Use the following steps when checking the system for leaks:
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 motor home dealer, or a qualified
Propane service representative to have an 11” Water Column Test
performed.
Liquefied Petroleum Gas (Propane) is heavier than air and will settle to the lowest
point which is generally the floor of the motor home. The detector is also sensitive
to other fumes such as hair spray of which most contain butane as the propellant.
Butane, like Propane, is heavier than air and will settle to the floor level where it will
be detected. When this occurs, press the reset button to stop the alert sound for 60
seconds.
The Propane Gas Detector is powered by the motor home coach batteries and/or the
inverter. The detector will operate properly until the battery is drained down to 10 volts
(a low battery condition is 10.4 volts). If the power source (battery and/or inverter) is
disconnected, or if the power is otherwise interrupted, the detector will not operate.
The Propane Gas Detector has a self check circuit which runs at all times when the
detector is powered. In the event that the circuitry fails, a failure alarm will sound. It
is a continuous series of short beep tones between long intervals and is distinctively
different from the alert sound.
New Coach Odor: The glues and other materials used in manufacturing the coach
produce vapors which may be detected when the coach is closed up. Air out the motor
home thoroughly.
Keeps Beeping: The gas detector beeps about once every minute, even when it is turned
off. The problem is a weak battery in the smoke detector, similar to the alert sound of the
Propane Gas Detector.
Hair Spray Triggers the Detector: Most aerosol hair sprays use butane gas as the
propellant. Butane, like Propane, is heavier than air and will settle to the floor level where
it will be detected.
Other Gases: Other gases which can cause the detector to respond with an alert include
the vapors from any fuel, liquor, alcohol, deodorants, colognes, perfumes, wine, adhesives,
lacquer, and most cleaning agents.
Slow Beep Rate: This could be the failure alarm and will occur in the event that the circuitry
fails. It is a continuous series of short beep tones between long intervals and is distinctively
different from the alert sound.
If the problem still exists: Contact the detector manufacturer for assistance.
TO AVOID EXHAUST GAS ENTRY INTO THE MOTOR
HOME, KEEP WINDOWS CLOSED WHEN THE CHASSIS
OR GENERATOR ENGINES ARE RUNNING.
