What to check before ordering

  • Verify the exact model’s outlet setting and permitted inlet conditions.
  • Check total appliance demand against its capacity at the published test conditions.
  • Plan vent orientation and weather protection with the installer, including the required pressure and leak checks.

Service reminder: Keep water and debris out of the vent and use only the vent-piping arrangement allowed for that model. A regulator that has been underwater should be replaced.

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.
