I have a Heatilator 3036 that uses convection to distribute heat. The unit is old but in good condition (all panels tight, no rust/erosion of metal) and I'd like to add a blower to put out more heat. The room air intake appears to be a 1" x 36" slot at the bottom front so I could make a plenum and drive it with a bath fan. Is this possible? I've seen such fan setups (low profile plenum with fan at one end that lays on hearth) but don't know if such was ever made for this unit (ie if the 3036 was designed for a blower). The plenum would have to be built to allow clearance/usage of the slide vent at the bottom (to get air to the fire), but this isn't a major issue.
