Description
This gas pressure regulator from Honeywell is a thermostatic draught regulator intended for solid fuel boilers. Its built-in thermostat measures the boiler temperature and, via a lever with a chain, opens or closes the air damper to control combustion. It is compatible with solid fuel boilers from Burnit, Wirbel, Viadrus, Buderus, KCHM, Zota, Atmos, and Don.
Further details

| Purpose | controls the combustion process by changing the air supply |
Choosing and fitting
Parts of this type are selected by flue pipe diameter and draught adjustment range. To ensure a proper seal, the regulator must match the flue pipe size. Install in a vertical or near-vertical flue section with the flap horizontal, and verify the flow direction marking. Before ordering, measure the flue diameter and check the existing regulator's orientation.
Signs of failure
When the hinge or flap seal becomes worn or sticky, the regulator may fail to maintain consistent draught, causing unstable combustion or overfiring. Check the hinge and seal for wear, sticking, or damage, and ensure the flap moves freely.
