Perfect solution for negative air pressure! Self-cleaning Master-Fit Plus models feature a blower that produces a power-induced draft of makeup air prior to ignition. This allows more efficient control of heat through the flue collector, making it ideal for installations where negative air pressure poses a problem. Available at AppliancesConnection
