What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

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

Control mechanism	built-in thermostat measures temperature and controls air supply via lever with chain
Function	controls the combustion process by changing the air supply to the boiler
Installation orientation	vertical or near-vertical section of flue with flap horizontal
Key parameter	flue pipe diameter and range of draught adjustment
Operation principle	gravity-operated counterbalanced flap opens at set draught level
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.
