Jumping primary "F" terminals

Hello all:

I've been reading a lot of conflicting information on the internet about how to, and how long you can leave the "F" terminals on a primary jumped. If I want to leave the terminals jumped, for say five minutes while doing testing, will I cause any harm? BTW, I'm talking about a basic Honeywell/Tradeline model R8184G, the one with the red reset button.

Thanks

Jumping the F-F terminals will bypass the safety circuit in the Honeywell primary control. Doing so will not harm the control whatsoever, I do it to make priming the pump faster. HOWEVER, once the control turns off (boiler reaches temp or manually reset), the control will NOT allow the burner to restart, it's a safety feature courtesy of Honeywell I suppose.

Thanks for the reply and apologies for not responding sooner. I was afraid I might burn out my ignition transformer.

Regards, T
