When to Replace

• Restricted Gas Flow:If the heater flame is unusually small or the heater struggles to remain lit despite a full tank.
• Hose Degradation:Any signs of cracking, fraying, or stiffness in the rubber hose material.
• Connection Leaks:If a soapy water test reveals bubbles at the crimped fittings or the QCC1 nut.

Installation Tips

• Hand Tighten Only:The QCC1 (large black nut) should be tightened by hand onto the propane tank valve; do not use a wrench, as it may damage the internal O-ring.
• Filter Placement:Always install the fuel filter directly onto the heater's gas inlet before attaching the hose to ensure maximum protection.
• Leak Testing:After installation, apply a soap and water solution to all connections while the gas is on to verify there are no leaks.
• Storage:When not in use, disconnect the hose from the tank and heater to prevent the accumulation of oils within the line.
