Description

Utica-Dunkirk 43800013 Hot Surface Ignitor
A replacement hot surface ignitor used in specified Utica 90% condensing boilers to ignite the burner during a call for heat.

Key Features:
  • Replacement hot surface igniter kit intended to replace a defective hot surface igniter
  • Kit contents (as listed by the manufacturer):
  • Hot Surface Igniter (1)
  • Hot Surface Igniter Gasket (1)
  • Installation Instructions (1)
  • Manufacturer notes there are two different igniters used in the 90% condensing boiler line that may look similar but have different insertion depths, so the correct igniter must be used for the correct boiler model
  • Manufacturer bulletin indicates the replacement igniter kit part number remains 43800013 even across igniter design changes for the UB90-100 series

Compatibility & Applications:
  • Manufacturer installation instructions identify P/N 43800013 for 50/75/100 BTUH 90% condensing boiler models (manufacturer designation)
  • Must only be used where the manufacturer specifies this exact part number: 43800013

Installation & Operation Notes:
  • Installation should be performed by trained/qualified personnel; the manufacturer states installing and servicing heating equipment can be hazardous due to gas and electrical components
  • Follow the boiler's service/installation documentation and the igniter kit instructions, including key manufacturer safety/setup notes:
  • Turn off electrical power to the unit (more than one disconnect may be required) and set the thermostat to the lowest setting or "OFF"
  • Turn off gas at the external shut-off; on 50/75/100 BTUH models, turn the electric switch on the gas valve to "OFF" (manufacturer notes larger models may not have a gas valve switch)
  • Wear gloves as sheet metal edges may be sharp (cut hazard)
  • The igniter is extremely fragile; failure to support the burner assembly can damage the igniter
  • Use the included new igniter gasket
  • Pay special attention to orientation: the igniter mounting bracket is stamped "outside," and the word "outside" should be readable when fully seated; if not readable, the igniter is not oriented correctly and must be removed and reinstalled correctly
  • Manufacturer system check-out steps include observing the ignition sequence, verifying smooth ignition and a clear blue flame, and checking for air leakage around the igniter/mixer area

Maintenance & Troubleshooting:
  • This part is typically replaced when the boiler has ignition problems traced to a defective hot surface igniter (manufacturer usage description).
  • Manufacturer troubleshooting guidance highlights conditions that can contribute to igniter-related reliability issues and should be checked during system checkout, including:
  • Short cycling / defective thermostat conditions (example causes listed by manufacturer)
  • Under-firing / low input (verify firing rate per rating plate guidance)
  • High return water temperature (verify proper flow for the installed radiation components)
  • Incorrect venting (verify venting and ensure intake/exhaust terminations are properly installed and not reversed)
  • Manufacturer cautions that severe air leaks (including around clean-out panels on older models) can affect pressure switch operation and lead to no ignition or erratic burner operation

User Reviews & Q&A Summary:
  • Reviews commonly describe it as the correct replacement part used to restore heat when the existing ignitor was failing.
  • Installation feedback frequently emphasizes handling the ignitor carefully and following the included directions due to the part's fragility.
  • Many comments focus on purchasing experience (availability, shipping speed, and customer support), with some noting that confirming the correct part number/model match was important before ordering.

Great company

We can't begin to describe how good this company is. They are the gold standard for working with a homeowner that has Minimal knowledge about boilers and expansion tanks! The staff are very knowledgeable about the process of installing and troubleshooting all things having to do with water systems, pressure tanks and miscellaneous equipment!!! Prices are reasonable compared to other outlets! Shipping was very fast which is very important when one has no hot water!!! 😁

AMAZING IS AN UNDERSTATEMENT!!

After trying several other suppliers, SUPPLYHOUSE was recommended. Amen!! SUPPLYHOUSE is the ONLY place you need to go. The parts are first class, VERY competitive priced, shipped ASAP, and the CUSTOMER SERVICE is like none other. I promise you won't be disappointed. Amazing truly is an understatement and breath of fresh air in today's world. If 10 stars were an option, I'd leave 20 more.

when my tech tells me, my igniter is going, Supply House

My Boiler company tech informed me that my boiler igniter is going out. So instead of paying over $700, I will use Supply House and order one for less than $140.
