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.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

This EBM PAPST centrifugal fan (model NRV137/2000-3633-010204, SKU 55720.10000) is a replacement for Beretta boilers including Condexa Pro3 230 IN, Power Plus Box 1002 P INT, Condexa Pro3 115 M, and Condexa Pro3 230 IN C 2 vie. It provides a tacho feedback signal compatible with the burner control. The fan supplies combustion air and drives flue gases out of the heat exchanger in room-sealed appliances, and its speed sets the firing rate in modulating premix burners.

Further details

Application type	Burner/Boiler combustion air supply and flue gas extraction
Control mode	Direct mains, PWM, or 0-10 V
Key function in system	Supplies combustion air to the burner; in room-sealed appliances, also drives flue gases out of the heat exchanger; in modulating premix burners, the fan speed sets the firing rate
Typical failure modes	worn bearings, impeller imbalance due to dust or debris deposits, a failed capacitor (if fitted), and speed feedback errors that the burner control interprets as an airflow fault, often causing a lockout

Choosing and fitting

Fans of this type are selected by matching required air flow at a given pressure, outlet direction and orientation, impeller diameter, supply voltage, and control mode (direct mains, PWM, or 0-10 V). The mounting flange pattern must match the boiler or burner chassis. Before ordering, compare mechanical dimensions and electrical connections with the original. Verify the control signal type accepted by the burner control; if the original used tacho feedback, the replacement must provide a compatible signal.

Signs of failure

Typical failures include worn bearings, impeller imbalance from dust or debris deposits, a failed capacitor if fitted, and speed feedback errors. The burner control may interpret these issues as an airflow fault, often causing a lockout. Check for shaft play, unusual noise, and verify the speed feedback signal.
