Cozy Heating Systems 49820 High Altitude Orifice Blank Kit for Gas Wall Furnaces

The Cozy Heating Systems 49820 is a 45-1 high altitude orifice blank kit designed for use with Cozy gas-fired vented room heaters, including radiant and closed front wall furnace models. This OEM replacement kit is essential for proper furnace operation at elevations above 2,000 feet where oxygen levels decrease and affect the air-to-fuel ratio.

Key Features:

• Official OEM part manufactured by Cozy Heating Systems
• Designed for high altitude applications to optimize combustion efficiency
• Helps prevent overfiring and ensures safe operation in low-oxygen environments
• Compatible with select Cozy wall furnace and vented console heater models
• Includes orifice blanks to properly adjust gas flow for altitude compensation

High altitude kits are critical for gas furnaces installed above 2,000 feet, as factory-installed orifices are sized for sea level operation. This kit ensures your Cozy heater maintains proper combustion, efficiency, and safe operation in mountainous regions by adjusting the fuel input rate to compensate for reduced atmospheric pressure.
