What to check before ordering

Identify the required intermediate outlet pressure and the inlet conditions for this stage.
Compare the connected appliance load with the capacity published for the same inlet and delivery conditions.
Ask your gas installer to confirm the vent position, weather protection and commissioning checks before installation.

Service reminder: Include vent condition in routine service. Debris, insects, snow or water can obstruct it; any vent extension must follow the model instructions. Replace a regulator that has been submerged.

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.
