Reznor 196688 Air Restricter protecting the heat exchanger and

protecting the heat exchanger and circulating pumps from premature failure

primarily within the 700 series and specific Unitrol configurations used in commercial boilers

does not exceed this capacity

Common causes include restricted return air

Can I use this if my old capacitor doesn't have a resistor

Reznor 196688 Air Restricter protecting the heat exchanger andThe Reznor 196688 Air Restricter is a critical combustion air management component engineered specifically for Reznor UDAP and UDAS unit heaters. This primary air restrictor is precision stamped to regulate the volume of air entering the venter motor assembly, ensuring the stoichiometric ratio remains within factory tolerances. Maintaining the correct combustion air flow is essential for preventing premature heat exchanger fatigue and ensuring stable
