Utica-Dunkirk 14662046 Transformer

is this a 4 wire transformer for a quantum 90-100 boiler?

Yes, this is a 4 wire 120V primary to 24V secondary, 50VA Transformer. We would need the completed unit model and serial numbers to make sure if it is the same one in your unit though. Thanks.

Is this for the year of 2018 with Dunkirk boiler model # DXL-100

The factory requires the serial numbers from the unit for confirmation. Please provide the serial numbers. Thank you.
