Honeywell Resideo VR8305Q 4153 Furnace Gas Valve
1. General Description
The Honeywell Resideo VR8305Q 4153 (also known as Honeywell VR8305Q4153, VR8305Q4153T, and Honeywell VR8305Q-4153/B) is a gas valve. It has 2 stages and uses dual direct ignition.
This manufacturer designs this valve for residential hot surface and direct spark systems. People commonly use it in direct ignition systems for gas appliances. This includes the Lennox 78L6001 2-Stage Furnace Gas Valve replacement.
The valve works at 24 VAC. It can handle about 30 to 415 cubic feet per hour (cfh) of natural gas.
It has a manual valve, two automatic operators, and a pressure regulator. This keeps the outlet pressure steady, even when supply conditions change.
You can mount it at angles from 0° to 90°. It has easy top-access adjustments and wiring. It supports both natural gas and LP gas, with conversion kits available.
