1. General Description of Honeywell VR8305Q 4153
The Honeywell Resideo VR8305Q 4153 (also known as Honeywell VR8305Q4153, VR8305Q4153T, and Honeywell VR8305Q-4153/B) is an advanced gas valve featuring 2-stage control and dual direct ignition architecture.
This manufacturer-designed valve is built specifically for residential hot surface ignition (HSI) and direct spark ignition (DSI) systems. It is commonly utilized in direct ignition systems for gas appliances, including serving as a reliable replacement for the Lennox 78L6001 2-Stage Furnace Gas Valve.
Operating at 24 VAC, it handles a gas capacity of approximately 30 to 415 cubic feet per hour (cfh) of natural gas. It integrates a manual valve, two automatic operators, and an internal pressure regulator to maintain steady outlet pressure even when supply conditions fluctuate. With 0° to 90° mounting flexibility, easy top-access adjustments, and support for both natural gas and LP gas via conversion kits, it stands as a premier choice for HVAC professionals.
