Coal Trol/Keystoker/Dual Blowers

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I purchased a Keystoker 105 with the Coal Trol.

In my setup I want to use my oil furnace blower. Need it to come on when the Keystokers 350cfm blower comes on. How exactly do I wire the Coal Trol to operate both blowers? Thanks!

You will probably have to hook an external relay, the output of the coaltrol to the blowers is only 2-3 amps, I believe. The furnance blower proably draws more than that....

Neil/Paul would probably have more insight....

I've sent you a PM about this. We offer a set of dry contacts on our Advanced models that is specifically for this purpose. It can be wired to the control circuit of your furnace to turn on the blower under the control of the Coal-trol. Please contact us for more information so a change to your order for the Keystoker can be made should you want to take this option. 315-299-3589.
