The BF-20 offers convection heat from the blue flame burner that produces an inviting atmospheric warmth quickly and efficiently. The BF-20 is equipped with a modulating hydraulic thermostat that modulates from 8,500 Btu to 20,000 Btu for continuous temperature control.
Here is how the thermostat works:
The gas control modulates from a minimum input of 8,500 Btu/HR (LO setting) to a maximum input of 20,000 Btu/HR for LP gas (HI setting) or 18,000 Btu/HR for Natural Gas (HI setting). The hydraulic thermostat bulb which is located at the casing assembly bottom adjusts the main burner flame between minimum input and maximum input.
Note: When the hydraulic thermostat bulb is "satisfied" the main burner flame will shut "off " with the pilot flame remaining "on ".
The LO and HI setting has temperature range of approximately 55°F to 90°F , respectively. This is the temperature at the hydraulic thermostat bulb not the room temperature. The owner is advised to determine the particular heat setting that is desired for comfort, as heating requirements are different for every owner.
