Confirm every one of these

  • The appliance manual states low-pressure LP and gives the required regulator outlet pressure.
  • The appliance inlet is exactly 3/8 in male SAE flare, not NPT and not another nominal size.
  • The hose length, capacity, routing, heat clearance, and safety listing meet the current appliance instructions.
