So could i safely cover over just a little of the plate with the holes with maybe a solid metal plate but still leve some air to penetrate and rake some ash down into the pan?? Would like your suggestions. I know my furnace is mainly for coal, but burning wood save on coal some time. Thanks all.
Your logic here is to slow down combustion air from going up thru the burning wood so fast. A manual pipe damper would have the same effect. IS there a manual pipe damper installed? The only thing I can think of to slow the burn would be to close the MPD some so that combustion air will come in slower.. Are the primary and secondary combustion air inlets closed while it burns the wood up that fast? Are the door seals in good condition and sealing well?
