The Honeywell VS820A1336 is a millivoltage combination gas control valve specifically designed for safe and efficient regulation of Liquid Propane (LP) gas flow in various propane-fired appliances. This durable iron unit (around 3-4 lbs) features a standard 3/4-inch inlet/outlet size for compatibility with most propane furnaces and water heaters.
Millivoltage Operation valves relying on a constant voltage supply, this millivoltage model operates on a low voltage signal typically around 750 millivolts (mV). This millivoltage signal is generated by the appliance itself when it needs heat.
Precise Pressure Regulation The valve features an internal pressure regulator that ensures a consistent ½ psi gas pressure delivered to the burner assembly. This consistent pressure is crucial for optimal combustion efficiency and reliable heating performance.
Safety Features For added safety, the VS820A1336 is equipped with a standard pressure regulator and a thermal shut-off mechanism. The regulator prevents excessive gas pressure, while the thermal shut-off automatically stops gas flow in case of overheating.
With a wide operating temperature range of 32°F to 175°F, the Honeywell VS820A1336 is suitable for use in various climates. Its maximum regulatory capacity of 335,000 BTU allows for compatibility with most residential propane-fired heating equipment.
Replacing a worn-out VS820A1336 with a new one can significantly improve your appliance's safety and performance. The millivoltage operation makes it compatible with various control systems, while the consistent pressure regulation ensures efficient fuel usage. Before ordering a replacement, be sure to consult your specific unit's manual for compatibility information.

Signs of a Faulty VS820A1336 3/4 Lp Gas Valve Millivolt Resideo:
Identifying a faulty Resideo VS820A1336 gas valve can be crucial for ensuring the safe and efficient operation of your gas-fired appliance.
Ignition issues:
Furnace or boiler won't ignite: If your appliance tries to start but fails to ignite the burner, the 3/4 Lp Gas Valve Millivolt VS820A1336 could be malfunctioning. This could be due to a weak pilot flame, a faulty millivolt coil, or issues with the valve mechanism.
Pilot light problems: A constantly flickering or failing pilot light could indicate a weak gas flow, clogged pilot orifice, or malfunctioning pilotstat within the VS820A1336.
Gas odor: This is a serious safety concern. Call a certified expert and turn off the gas supply right once if you smell gas close to your appliance. A faulty 3/4 Lp Gas Valve Millivolt VS820A1336 could potentially leak gas if its internal seals or valves deteriorate.
Unusual behavior:
Gas valve noise: Listen for any unusual hissing, clicking, or buzzing sounds coming from the VS820A1336. These noises could indicate internal component failures or gas leaks.
Uneven heating: If your appliance isn't heating evenly or consistently, it could be due to inconsistent gas flow from the 3/4 Lp Gas Valve Millivolt VS820A1336.
Additional notes:
Regularly inspect your appliance for any visible signs of damage on the VS820A1336, such as rust, corrosion, or cracks.
If you notice any of the above signs or suspect a problem with your gas valve, always consult a qualified technician for diagnosis and repair. Never attempt to fix gas appliances yourself due to the potential safety hazards.
Remember that the VS820A1336 gas valve and your gas appliances cannot operate safely or effectively without proper installation and maintenance by a competent technician.
