Several of the appliances use propane to operate: the drop in stove top, furnace, gas hot water heater, and refrigerator. Gas is supplied through the use of a 20 pound propane tank (a double tank option is available). Gas flow is measured by an adjustable regulator mounted just off the tank itself. A gas hose connects the regulator to the trailer after which the gas flow is through ¼ type L soft copper tubing. This tubing is fastened down with metal clamps. All fittings are flared. If an appliance is to be removed, repaired or added, take special care to tighten all fittings carefully, using only flared fittings if adding an appliance. WARNING: Do not use any gas appliance after repairing or changing the system without checking for gas leaks. Do not smoke, use lights, or matches until this has been done.
To use the propane gas system the gas must first be turned on at the tank. Initially the gas lines will be filled with air which must be cleared for most of the appliances to operate correctly. Light the drop-in stove first as this is the best way to clear air out of the lines. The light the refrigerator, furnace and last the gas hot water heater.
Annually, and anytime repairs or changes are made to the gas system where fittings are loosened, the system should be checked for leaks.
