Draft regulator FR1 30-90°C, 3/4 inch male thread 42294

Temperature control in solid fuel boilers

The FR1 draft regulator is a reliable device designed for smooth adjustment of air supply to the furnace in boilers fired with solid fuels. Its task is to maintain the optimal water temperature in the heating installation, which translates into efficient combustion and fuel savings. Mounted directly in the boiler's water jacket, the regulator reacts to temperature changes, automatically adjusting the position of the ashpit damper.

Construction and principle of operation

The regulator's construction is based on a thermostat placed in a brass sleeve with a 3/4 inch external thread. The connection between the thermostat and the ashpit damper is made using a lever and a chain. As the water temperature in the boiler changes, the thermostat adjusts the position of the damper, controlling the amount of air supplied. This ensures a stable and efficient combustion process. The regulator can be mounted both vertically and horizontally, making it easier to install in various boiler configurations.

Key features and benefits

• Precise regulation: Temperature regulation range from 30 to 90°C allows for accurate adjustment of the boiler operation to current heating needs.
• Durable construction: Made of brass, it ensures corrosion resistance and long-term reliability of the device.
• Universal mounting: The possibility of mounting in a vertical or horizontal position facilitates installation even in tight spaces.
• Automatic operation: The regulator operates fully automatically, eliminating the need for manual adjustment of the air supply.
• Application in water installations: Designed for use with heating systems using water or a water-glycol mixture (in accordance with VDI 2035 standard).
• Wide damper load range: The regulator copes with various types of ashpit dampers thanks to the load range from 100 to 600 grams.
• Easy calibration: Allows precise adjustment of the operation to the specifics of a particular boiler and fuel.

The FR1 draft regulator is a solid and functional solution for anyone looking for a reliable way to optimize the operation of a solid fuel boiler and ensure thermal comfort in their home. The device complies with EN 14597 standard, which confirms its safety and high quality of workmanship.
