Mechanical boiler draught regulator Honeywell FR1243/4A 3/4"

Boiler draught regulator mechanically regulates the amount of air that enters the combustion chamber, thru the primary air inlet in central heating boiler or furnace.

The boiler draught regulator Honeywell FR1243/4A has a scale, to set the desired boiler temperature setpoint.

The mechanism opens and closes the boiler primary air flap, which helps to keep the desired temperature of central heating at a constant level. The principle of the Honeywell draught regulator relies on the thermostatic head, which responds to the temperature changes of the water circulation in the heating system.

Boiler draught regulators are for manually loaded solid fuel fired boilers and furnaces of a central heating system. Installation and subsequent operation of a draught regulator can be vertical or horizontal.

To be able to use the Honeywell boiler draught regulator FR1243/4A some boilers may need a brass faucet extension, to facilitate the transition from the 3/4" thread to a 1/2" thread (thread diameter is boiler dependent).
