Product Description

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

A twin-stage unit puts two pressure-reduction stages in one assembly. The model you choose still needs the correct final pressure and capacity for the job.

Product type	Twin-stage LP gas regulators
Part / SKU	LV404B4V9

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.
