delivering precise combustion airflow to maintain proper static pressure across both high and low-fire cycles

Key Benefits Optimized Airflow: The 33-degree pitch is precision-engineered to maximize heat exchange efficiency across the condenser coils

Pressure drop should be monitored during routine maintenance

making it a reliable choice for maintaining optimal boiler operation and protecting against carbon monoxide buildup

Smith Cyclone series risks CO leakage and inefficient fuel-to-air ratios
