ADCERAX supplies silicon carbide furnace igniters for gas-furnace replacement and OEM projects, with flat and cylindrical constructions for different installation requirements.
Explore the available base and connection styles, then compare the mounting position, electrical requirements and ignition timing with your original part or furnace drawing.
Silicon carbide furnace igniters are hot surface ignition components that use electrical resistance to heat a SiC element and ignite gas at the furnace burner. Available as elements or assemblies with ceramic bases, leads and connectors, they must match the furnace’s electrical requirements, ignition timing and mounting position.
CONFIGURATION OPTIONS
Use the complete furnace or HVAC model and original part first, then review the element form, ceramic base, holder or bracket, leads and connector shown with each structure.
Furnace
Compact ceramic body, insulated leads and a keyed plug create a defined service connection.
Original equipment references
Before selection: connector keying, lead length, body orientation, hot-zone position and equipment suffix.
Furnace
The element exit and ceramic-body shape differ from a straight compact base, affecting installed position.
Original equipment references
Before selection: mounting plane, insertion depth, plug, lead route, electrical conditions and supplied parts.
Rooftop HVAC
A plug-connected igniter is shown with a separate mounting gasket, retaining clip and fasteners.

A flat element, ceramic body and individually terminated leads are shown with several separate mounting bracket shapes.
Original equipment references
Before selection: complete equipment model, selected bracket, mounting plane, lead terminations and electrical/control conditions.
Furnace & HVAC applications
Overall part length cannot tell you where the active element will sit. The base, bracket and mounting face establish its reach and orientation beside the burner.

Furnace igniter customization
Bring your existing part, sample or furnace drawing. Discuss the element geometry, electrical requirements and connections needed for your equipment, from replacement sourcing to a new OEM design.
01
Element & Base Geometry
Start with the space available inside your furnace and the position the active element needs to reach. Review the element and ceramic base as one installed configuration.
A defined geometry gives the replacement or OEM review a clear reference.
02
Electrical Requirements
Bring the original igniter rating and ignition-control reference together. These details establish the operating requirements that a proposed configuration needs to meet.
Electrical suitability can be reviewed alongside the physical fit.
03
Leads & Connections
Define the connection around your equipment harness and available routing space. Include the installed lead path so the assembly requirements are clear.
Connection differences can be identified before an assembly is selected.
Your starting point
A change to the base or element length affects where the igniter sits beside the burner. Use the mounting face as the shared reference when comparing an existing part with a proposed custom configuration.
Use the original part as a starting point.
Compare the seating surface, element exit and lead direction when discussing a revised configuration.
Mounting face
The surface that locates the assembly in your furnace.
Active-zone reach
The distance from that reference to the required hot-zone position.
Installed clearance
The required space around the element and adjacent burner components.
Your starting point
A complete specification is helpful, but an original part number, clear photos or an existing drawing can begin the discussion.
Replacing an existing igniter?
Share the original part number and full furnace model. Photos of the whole part, base and connector help identify the configuration to review.
Developing an OEM furnace?
Share the drawing revision, available installation space and ignition-control requirements. Identify which dimensions and interfaces must remain fixed.
Have an old sample, but no drawing?
Start with photos, markings and the dimensions you know. The review can identify the additional measurements or specifications needed to proceed.
Discuss the configuration your furnace needs.
Send your reference part or drawing and highlight what needs to stay the same or change. Once requirements are agreed, the drawing and parts list provide a reference for sample evaluation and later orders.
Match the igniter to your furnace’s electrical output, ignition timing and installed geometry. Use the original part reference or drawing to define the requirements for replacement or OEM evaluation.
💡 Quick Selection Guide:
Electrical match: Verify voltage, cold resistance and warm-up requirements.
Installed fit: Compare the mounting face, element reach and burner clearance.
Part identification: Keep the full furnace model, original part number and drawing revision together.

FAQ
Leads, connectors, brackets, clips, gaskets and fasteners can be specified with the igniter. Share your required lead length, connector photos and mounting details so we can review the assembly requirements. Your quotation will confirm which components are included.
Provide the drawing revision, mounting envelope, lead or connector requirement, electrical/control conditions, quantity and acceptance criteria.
Some furnace controls use different warm-up periods for the first attempt and subsequent trials. Identify the installed control and its specified sequence when defining the igniter’s heating-response requirement.
Not necessarily. A furnace can have low-voltage control circuits and a separately powered hot surface igniter output. Use the specified HSI output and original part rating to select the igniter.
Send the original number with the furnace model or a photo of the installed part. It gives the review a starting point. Any proposed assembly should be checked against the original electrical requirement, mounting position and connection before a replacement is approved.
Yes. Start with clear views of the whole part, ceramic base, connector and any markings. Include the furnace model if available. You can discuss which measurements or specifications are still needed before moving to a sample or quotation.
Use the sample option below and state the quantity you want to evaluate. Ask for sample availability, cost and timing for that assembly, and agree the acceptance points before purchase. Keep the accepted drawing or part revision as the reference for a later quantity order.
For a furnace replacement or OEM project, share the details you have:
A part number, photo or drawing is enough to start. We’ll review the furnace fit, connection requirements and requested supply scope before confirming a quotation.
