id see how many CFMs your fan is pushing, and find one compatible. home systems lack the punch of a can fan, i think.

Wait. What? Gas boiler? Sorry to be a square but isn't that vent for carbon monoxide and other poisonous gasses from gas/oil combustion? And aren't they sized perfectly for passive venting and if you start fucking up the flow with pressurized air it'll push all the CO into your living space?
