is this a series 2, with standing pilot, the relay does 2 things with the series 2, starts the pump and initiates the gas train into operation. also check the pump for power at the pump. marc

WETHEAD QUESTION !!

I have a Burnham Boiler(96K, Natural gas, standing pilot) I'm not getting power to the circulator(pump), is it possible that the Honeywell relay (R8285D) may be at fault ? If not, what other problem might there be ??

If the R8285D relay is pulling in and the boiler is firing, then I would suspect that one of the wires may be loose. behind the relay in the junction box there will be two black wires coming out of the relay plate. These both need to be connected to the incoming 120v hot (black) wire. This is done in the field and I have seen several times where the second wire wasn't connected or was loose in the wire nut. You also need to be sure that the white neutral wire from the pump is connected to the rest of the whites in the box. The circulator hot wire should be connected to the yellow wire in the junction box. Check for current on this wire when the relay is activated. It is rare for contacts in these relays to be bad. Hope this helps.

I took wires apart at pump.............no power at the pump, Will check for loose wiring in the J-Box behind relay. Yes the boiler does fire.
