Wiring Honeywell Primary R7184U

I have a customer whose primary control went bad. I picked up an R7184Ucontrol. There are optional leads for a solenoid valve as well as a limit. Do you just cap them and not use them, If I don't need them or will that create an open circuit?. Also seems they want ignitor wire to go to ignitor and orange motor wire to go to motor separately. I'm used to bugging all 4 wires together. Is there a difference if do separately?

Thanks

Joe

    try

    You should try to use as many wires as possible, but you don't have to use them all. Orange to the motor and blue to the ignitor is always a good idea. If you don't have a valve you can't hook up the violet wire.

    Like it!

    "Use as many wires as possible" Very good advice! My suggestion is to read the little white folder that came with the control,explains it all

    reading the little white folder

    Yeah I read the little white folder. it says valve is optional on specific models,but doesn't spell out to cap it. i wired it according to instructions and the new control isn't coming on. wired direct to burner and burner fires. so i'm assuming i'm wiring it wrong, but don't see where.

    thanks

    .

    The red and black wires tie together and go to the power coming to the burner from the limit control.

    I would first

    Is this a boiler, or warm air?  If my mind serves me right, this is a pre/post purge option control. Limit is powered by B-1, and L-1 is live all the time for a post purge. If only a B-1 connection, both Limit and L-1 need to tie into B-1. Orange is motor, Blue is ignition (if you want interupted). Purple is for an oil valve. You need one to have a pre/post purge. I'm thinking, as it has been law here for decades to have an oil cut off valve, so never needed to do this, but I would say that you will need to turn off your valve on/off delay by setting the dip switches. I think that will work for you. Worst case scenario, add a clean-cut pump also, and use the wonderful features of this control.
