Heil Quaker ICP 1160416 Restrictor

The Heil Quaker ICP 1160416 Restrictor is a critical combustion air management component engineered specifically for high-efficiency gas furnaces. This vent blower restrictor is designed to calibrate the secondary heat exchanger's static pressure by modulating the flue gas flow rate. Proper installation of the ICP 1160416 ensures the induced draft motor maintains the correct air-to-fuel ratio, preventing pressure switch tripping and localized overheating within the heat exchanger. As an OEM ICP replacement part, it meets the exact tolerances required for Heil, Tempstar, and Comfortmaker furnace venting systems. Technicians should utilize this restrictor to resolve furnace combustion issues where airflow velocity exceeds design specifications, particularly in short-vent applications. Precision-stamped for durability, this ventilation baffle maintains system integrity under high thermal cycles, ensuring the IDM assembly operates within its engineered performance curve without premature mechanical fatigue.

• Ensures precise combustion air calibration for consistent ignition and flame stability.
• Optimizes flue gas velocity to prevent condensation buildup in the vent header.
• Direct HVAC OEM fitment for ICP-branded heating equipment, eliminating field modification risks.
• Reduces induced draft blower turbulence, contributing to quieter operation and stable pressure switch signals.
• Essential for maintaining AFUE efficiency ratings by controlling the heat transfer rate across the primary and secondary cells.

When should the 1160416 restrictor be installed?

This restrictor is typically required during the initial installation or when replacing a vent motor, specifically when the venting configuration (length or diameter) requires a reduction in air velocity to meet the manufacturer's manifold pressure and temperature rise specifications.

Will this restrictor fix a pressure switch that won't close?

If the furnace pressure switch is failing to close due to excessive or unstable draft, installing the correct ICP vent restrictor can stabilize the negative pressure produced by the inducer, allowing the safety circuit to complete.

Is the ICP 1160416 compatible with all Heil furnaces?

No, compatibility is model-specific. This part is designed for specific 90% plus AFUE condensing furnaces. Technicians must verify the furnace model and serial number against the factory parts list to ensure the correct orifice plate or restrictor plate is utilized.
