The fan motor is dual shaft...one side has combustion wheel and other side has room air wheel
Faster motor speed......more air flow thru BOTH sides.
Room air--- more air flow could be to fast that heat exchanger does get COLD
Combustion side...more air flow WILL upset the fuel/air ratio and flame may not even ignite. Propane system is only 11"WC (0.4 psi)---to much air/no flame or to little air/no flame
Propane orifice is metered to provide proper fuel flow to MATCH the air flow
Heat Exchanger is designed to transfer heat to room air based on HEAT generated by the MATCHED fuel/air at burner.
NO...a 33% Faster Fan Motor is NOT going to work
