Additional Checks
Check wire routings for any rubbing
Check for kinked pressure switch tubing.
Check flue elbow for alignment and clamp tightness.
Check screw tightness on blower wheel.
Check factory wiring and wire connections.
Check product for proper clearances as noted by installtion instructions
°F to °C formula: (°F - 32) divided by 1.8 = °C °C to °F formula: (°C multiplied by 1.8) + 32 = °F
