What to check before ordering

  • Check both the pressure arriving from the first stage and the required final outlet setting.
  • Use the full appliance demand and the manufacturer’s stated rating conditions when comparing capacities.
  • Have your installer check vent clearance, protection from weather, operating pressure and system tightness.

Service reminder: A matching pipe connection is only one part of the selection. Keep the vent clear, follow the specified vent orientation and piping requirements, and replace any submerged regulator.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.
