Utilities & SystemsWARNING: The pigtail hose must be installed to avoid tension orpulling stress at either end of the hose.WARNING: Keep the pigtail hose away from sharp edges of thecylinder collar, rigid corners, walls, doors or other compartmentstructures including the cover.NOTE: The regulator is typically installed with the inlet fittings at the same level asthe cylinder outlet valves. Due to bracket design, wing nut clearance or coverrestrictions, the regulator fittings may not be in perfect alignment with the cylindervalves. A variance of two (2) inches (5 cm) above or below the line will permit thehoses to be properly installed.TWO CYLINDERS (20# OR 30#) (44 OR 66 KILOGRAMS) IN ARECESSED COMPARTMENT OR HOUSING (FIG. 22)Follow these steps to insure the correct container/valveorientation, regulator placement, hose length, hose routing andcylinder cover placement for propane supply assemblies.1. Connect the 3/8” low-pressure hose to the outlet of thetwo-stage regulator.2. Place the cylinder on the bracket in the recesscompartment or housing and secure them so the outlet ofthe cylinder valves are facing the “sidewalls” of thecompartment or housing (opposite of each other).Fig. 223. Mount the regulator on the center back wall of thecompartment 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 theright hand swivel nut to the cylinder valve.WARNING: The pigtail hose must be installed to avoid tension orpulling stress at either end of the hose.WARNING: Keep the pigtail hose away from sharp edges of thecylinder collar, rigid corners, walls, doors, or other compartmentstructures including the cover.62 Jay Flight Conventional Travel Trailer and Fifth-Wheel Travel Trailer
