Burner and combustion parts
The parts that stop a burner from lighting, and the ones that stop it from staying lit.
| Covers | Flame safeguard, programmer, scanner, ignition, gas train, actuators |
|---|---|
| Model specific | Nearly all of it: the same control ships in several configurations |
| Scanner type | Ultraviolet and infrared see different flames |
| Must match | Control voltage, purge and trial timings, and the listing |
| Send us | Burner nameplate, part number, and a photo of the wiring |
A part number without a photo of the wiring is a coin flip.
4 things and we can price it
Get these in the first message and you get a price back, not a list of questions.
- 01 Burner nameplate Make, model, firing rate, and fuel. A photo is faster and removes transcription errors.
- 02 The part Part number off the existing device if legible, plus a photo of the device and its wiring.
- 03 Symptom What it is doing, if the part has not been positively identified yet. Often the fault points at a different component.
- 04 Down or not Whether the plant is out of service. It changes what we chase.
The short version
Flame safeguard and programmer, scanner, ignition transformer and electrodes, pilot assembly, gas train components, actuators and linkage. Between them these account for the large majority of burner lockouts that are not a fuel supply problem.
Almost all of it is model-specific. The same control ships in several configurations: different timings, different voltages, different terminal arrangements. So a part number without a photo of the wiring is a coin flip.
What makes it the right part
- Like-for-like or upgrade
- A direct replacement keeps the sequence and the wiring. An upgrade may bring better diagnostics or communications but usually changes the base and the wiring, which turns a one-hour swap into a panel job.
- The listing
- Safety components carry listings for a reason. Substituting outside the listing is not a cost decision, it is a code and insurance decision.
- Scanner type
- Ultraviolet and infrared see different flames. The fuel and the burner design decide which is correct, and swapping type without checking is a common source of intermittent flame failure.
- Voltage and timing
- Control voltage and purge and trial timings must match the existing sequence and the applicable code.
The rest of the room
- Trim & Safety The devices an inspector looks at first, and the ones with the least room for improvisation.
- Feedwater & Condensate Pumps, seals, and the level controls that decide whether the boiler ever sees water.
- Controls & Instruments Replacement controls and the sensors that feed them, usually on equipment nobody has the manual for.
- Gaskets & Consumables The cheap items that turn a one-day job into a three-day job when they are not on the truck.
- Retrofit Packages When the vessel is sound but the burner or the controls no longer meet the requirement.
