## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IRC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IRC 2009 Fuel Gas (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 18 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Burner is a defined term in the International Residential Code (IRC) 2009, in Fuel Gas. The code's own words are: “A device for the final conveyance of the gas, or a mixture of gas and air, to the combustion zone.” No other I-Code in this corpus defines it, so the IRC 2009 definition is the one to work from. The term is used in 18 chapters of this corpus, most often in Fuel Gas (IRC 2009), Building Services and Systems (IFC 2009), Definitions (IMC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

## What must be verified before using this guidance?

**Burner** is defined once in this corpus, in the [Fuel Gas](https://harth.build/resources/building-codes/us-states/maryland/irc-2009/fuel-gas.md) chapter of the International Residential Code (IRC) 2009:

> A device for the final conveyance of the gas, or a mixture of gas and air, to the combustion zone.

### The term in use

How the code actually writes about burner, quoted from the 2009 text hosted here:

> Each of the appliances served shall be interlocked with the mechanical air supply system to prevent main burner operation when the mechanical air supply system is not in operation.

— [IRC 2009 §G2407.9.2](https://harth.build/resources/building-codes/us-states/maryland/irc-2009/fuel-gas.md)

> The grade of fuel oil used in a burner shall be that for which the burner is approved and as stipulated by the burner manufacturer.

— [IFC 2009 §603.1.4](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/building-services-and-systems.md)

> A timer, if provided to control main burner operation, shall have a maximum operating time of 1 hour.

— [IMC 2009 §914.4.1](https://harth.build/resources/building-codes/us-states/new-hampshire/imc-2009/specific-appliances-fireplaces-and-solid-fuel-burning-equipment.md)


## Burner compared with Main Burner

These two are the closest pair in the 2009 I-Codes: about 48 per cent of their defining words are the same. The code states both and compares neither, so the difference is worth naming.

| | Wording unique to it |
| --- | --- |
| **Burner** (IRC 2009) | — no wording of its own |
| [Main Burner](https://harth.build/resources/glossary/main-burner.md) (IRC 2009) | group, devices, essentially, forming, integral, unit, takes, place, accomplish, function, appliance, designed |

Everything else in the two definitions is shared. If a project turns on which of the two applies, those words are the whole of the test — and a local amendment that edits one of them without editing the other moves the boundary between burner and main burner.

## The terms burner is built out of

The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what burner covers:

- **[Combustion](https://harth.build/resources/glossary/combustion.md)** — IRC 2009: In the context of this code, refers to the rapid oxidation of fuel accompanied by the production of heat or heat and light.
- **[Device](https://harth.build/resources/glossary/device.md)** — IRC 2009: Aunit of an electrical system that carries or controls electrical energy as it principal function.

## Burner: what to open, and in what order

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

| Check | Where | Confirmed |
| --- | --- | --- |
| Read the definition in the adopted IRC | Fuel Gas | |
| Re-check the requirement that uses it | Fuel Gas (IRC 2009) | |
| Re-check the requirement that uses it | Building Services and Systems (IFC 2009) | |
| Re-check the requirement that uses it | Definitions (IMC 2009) | |
| Re-check the requirement that uses it | Specific Appliances, Fireplaces and Solid Fuel-burning Equipment (IMC 2009) | |
| Confirm the dependent definition | Combustion | |
| Confirm the dependent definition | Device | |
| Local amendment to any of the above | Jurisdiction's amendment list | |

**A research aid, not a code determination.** The authority having jurisdiction decides which edition and which amendments apply.

## Frequently asked questions

### What is the code definition of burner?

The International Residential Code (IRC) 2009 defines it in Fuel Gas as: “A device for the final conveyance of the gas, or a mixture of gas and air, to the combustion zone.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

### Which parts of the code depend on burner?

In this corpus the term is used across 18 chapters, led by Fuel Gas in the IRC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

### What is the definition of a building according to the International Building Code?

Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as burner, which the IRC 2009 defines as “A device for the final conveyance of the gas, or a mixture of gas and air, to the combustion zone.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.

### What does "burner" mean in slang?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IRC 2009 states, in Fuel Gas: “A device for the final conveyance of the gas, or a mixture of gas and air, to the combustion zone.” It is defined in IRC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
