Heil Quaker ICP 1149710 Pilot Ignitor/Sensor Assembly

As a field tech, you know that a reliable ignition sequence depends on the integrity of the pilot assembly. The Heil Quaker ICP 1149710 Pilot Ignitor/Sensor Assembly is a critical OEM replacement part designed for intermittent pilot systems. This assembly is 100% identical to the Honeywell Q373A2115, featuring a low-output conventional target-type burner that ensures precise flame pattern stability. It comes equipped with a BCR-18 orifice specifically calibrated for natural gas applications and utilizes a 15,000V open circuit spark for consistent ignition. This intermittent pilot ignitor handles both the initial spark and subsequent flame sensing, sending a continuous microamp signal back to the ICM control module to prove the pilot before the main gas valve energizes. Whether you are servicing a Heil furnace, Tempstar, or Arcoaire unit, this flame sensor assembly provides the exact physical fit and electrical parameters required to prevent nuisance lockouts and "no-heat" calls caused by carbon buildup or cracked ceramics on older ignitor-sensor units.

Key Benefits:

• Genuine OEM replacement part ensures 1149710 and Q373A2115 cross-compatibility without bracket modification.
• Robust 15,000V spark ignition capability for rapid pilot lighting even in high-demand residential environments.
• High-sensitivity integrated flame sensor provides consistent microamp feedback to the ignition module.
• Factory-installed BCR-18 natural gas orifice and Type B mounting bracket for straightforward installation.
• Compatible with a wide range of ICP brands including Comfortmaker, KeepRite, and Day & Night.

Common Questions:

Can this assembly be converted for use with Liquid Propane (LP)?
While the assembly ships with a natural gas orifice, it is compatible with LP systems if the orifice is swapped for the appropriate propane-rated component. Always verify manifold pressure after any orifice change.

Why is my furnace sparking but the pilot won't stay lit?
This is often a result of a dirty pilot burner or a weak flame sensor signal. If cleaning the sensor rod doesn't restore the microamp reading to the module's "prove" threshold, replacing the 1149710 assembly is the standard professional fix.

Does this part replace the old thermocouple style?
No, this is for intermittent pilot ignition (IPI) systems. It replaces the electronic electrode/sensor rod assembly found in "smart valve" or electronic ignition sequences, not traditional standing pilot thermocouples.
