Fuel & Propane System 3. Mount the regulator on the center back wall of the compartment or housing so the vent is pointed downward. 4. Attach the 1/4” inverted flare x 18” Type-1 pigtail hose to the regulator inlet and the right hand swivel nut to the cylinder valve. Main Supply Hose – Low Pressure Attach the main supply hose from the regulator to the brass manifold fitting in the frame of the trailer. The swivel brass nut on the main hose will be your final attachment. Main supply hose Several things to remember each time the propane container is removed: 1. Check that ALL fittings are tight. 2. Check that ALL connections are tested with a propane leak detector (or soapy water) solution. 3. Open the main valve slowly to avoid a fast rush of propane to the excess flow valve causing propane freeze up. If you experience a propane “freeze-up,” close the main valve and wait at least fifteen (15) minutes before trying again. Refer to the regulator manufacturer’s operator manual. 4. Listen carefully - a “hissing” sound longer than one second may indicate a propane leak. If you feel there may be a leak present, close the valve and contact your dealer or qualified propane technician for repair assistance. Replace all protective covers and caps on the propane system after filling. Make sure the valve is closed and the compartment door is securely latched. Maintenance Propane gas is normally non-corrosive - you need not worry about the inside of your container. However, the outside should be kept free from rust by a periodic coat of paint in a light reflective color. Rust, scratches and/or dents can affect the safety of the cylinder. Inspect the cylinder at regular intervals. If there is a problem, have it evaluated by a qualified technician and discard it. DOT requires that a visual inspection be made prior to each filling. Any cylinder that has been exposed to Fire, leaks or seems damaged should not be refilled. Do not attempt to repair any containers, container valves, regulator or appliances by yourself. Use only trained certified propane gas service technicians to perform repairs. Propane cylinder recertification If you have an older RV you should know that, according to Federal law, DOT cylinders may only be used for 12 years after their manufacture date (the number of years for certification may vary in your area). After that, the cylinders must be “recertified” which provides another five years of use. The cylinders can be recertified every five years thereafter. Federal DOT (Department of Transportation) regulations require periodic inspections and re-qualifications of the propane cylinders. DO NOT USE damaged or rusted containers. Verify with your local propane dealer that all required inspections and certifications have 88
