Reznor 272742 Igniter
The Reznor 272742 Igniter is a critical OEM replacement spark ignitor designed for high-reliability sequence of operation in gas-fired heating systems. This spark electrode assembly provides the high-voltage discharge necessary to bridge the gap and ignite the main burner, ensuring consistent combustion in both residential and commercial units. As a veteran technician knows, a fouled or cracked ceramic insulator can lead to intermittent flame loss or "no-spark" calls. Replacing with a genuine Reznor heating part like the 272742 ensures the electrode remains properly aligned within the burner manifold, maintaining the specific micro-amp signal required by the DSI control board for flame rectification.
Engineered for durability in harsh industrial environments, the Reznor furnace igniter is compatible with a wide range of power-vented unit heaters and garage heaters. Unlike universal kits, this direct spark ignitor features a precise mounting footprint and lead length, eliminating the need for field modifications that can compromise safety. Whether you are servicing a Reznor UDAP, UDAS, or specialized duct furnace, using the 272742 spark ignitor ensures the system returns to its original factory specifications for energy efficiency and reliable startup cycles.
Key Benefits- Direct OEM Compatibility: Specifically engineered to fit Reznor unit heaters without modification, ensuring correct spark gap and electrode positioning.
- Durable Ceramic Insulation: High-grade ceramic housing prevents voltage leakage and withstands the intense heat of the burner box over long-term operation.
- Accurate Flame Proving: Maintains the millivolt/micro-amp signal integrity necessary for the ignition controller to sense and hold the flame.
- Simplified Field Service: Compact, single-screw mounting design allows for rapid replacement during maintenance or emergency repairs.
Is the 272742 Igniter compatible with propane (LP) systems?
Yes, this igniter is designed to operate with both natural gas and propane Reznor units, provided the burner assembly is original equipment.
Why is my Reznor heater sparking but not lighting?
While the igniter may be generating a spark, ensure the electrode is clear of carbon buildup and that the Reznor 272742 is positioned correctly. If the spark is weak or tracking to the ground, the ceramic may be cracked.
Do I need to replace the ignition cable with the 272742?
It is standard practice for contractors to inspect the high-voltage lead for brittleness or burns. If the cable shows signs of degradation, it should be replaced to ensure the 272742 receives full voltage.
