Installation Tips

• Ensure the propane tank valve is fully closed before installation.
• Hand-tighten all connections first to prevent cross-threading, then use a wrench for a final quarter to half turn.
• Apply a soap and water solution to all connections to test for leaks; bubbles indicate a leak.
• Do not overtighten fittings as this can damage the seals.
• Route the hose to avoid kinks, sharp bends, and contact with hot surfaces or sharp edges.
