I have recently installed an older Hurricane wood stove into my basement that has a heat exchanger built in with a blower on the back. The stove is sealed up great but when the blower is kicked on, it is slightly affecting the draft and drawing out carbon monoxide through either a small gap in the door or the combustion air intake knobs on the front. My thought is to install an 4” outside air intake with a variable speed inline exhaust fan and feed it to the bottom of the stove. Any thoughts or different ideas?
