FX37SPT/D22 – IGNITION CONTROL BOX WITH 22S PRE-PURGE DELAY.

The FX37SPT/D22 is a very reliable electronic ignition controller that is used in many gas appliances including boilers, fires, tumble dryers, etc. It has a 22s pre-purge delay built in. This means a separate timer board is not necessary.

If you have a requirement that is not covered by any of our standard products, please use our Ignition Control Specifier tool.

Important Notice: If replacing an FX37 that is more than 10 years old, you must check the connector on it as it could be different from the one on this control. All current FX37s have a green connector on them as shown in the picture on this page and require a mating half (also green) to be purchased separately only if replacing a very old version of the FX37 or an FX30SPT.

If a very old FX37SPT or FX30SPT has a grey or blue connector that slides straight onto the edge of the control, you have two choices as follows:

1. Buy a compatible replacement FX37-P16.

2. Buy a standard FX37SPT as here and also purchase a mating connector. You will then need to replace the old connector with this new connector.
