I have a couple of older model 801's that are being taken out of service and replacing it with newer ones. The older models have black control boxes and utilize a seperate relay for a 4 second delay of the high fire valve. The newer blue box models do not have the 4 second delay mounted near the valves like the older models. I am wondering if the newer model, with the blue box, has a built in relay somewhere? I have relays available if I need to instal them. Thanks for any info.
