Wood Burning Fireplace Parts Diagram of 2026 For Easy Fit

The Midwest Hearth 17-Inch Burner Pipe is an aftermarket replacement burner tube engineered specifically for gas log lighters in wood-burning fireplaces. Wood-burning fireplace owners frequently rely on gas log lighters to simplify the process of starting firewood without using excessive kindling or paper. Over seasons of high heat exposure and ash contact, factory burner pipes can warp, corrode, or clog. This standalone pipe is intended for homeowners seeking to restore their existing ignition setup without replacing the complete log lighter assembly.

In terms of operation, a log lighter burner tube distributes gas beneath a wood grate to ignite logs and establish an upward chimney draft. The manufacturer highlights that this pipe helps heat the chimney flue quickly, which aids drafting and promotes cleaner startup conditions. Because this listing covers only the replacement tube, the unit relies on your existing gas supply line, shutoff valve, and compatible air mixer to deliver and ignite the fuel charge beneath your firewood stack.

Built from low carbon steel containing between 0.05 and 0.30 percent carbon, the pipe balances toughness and heat tolerance with economical maintenance. It measures 17 inches in length with overall dimensions of 17 by 1 by 2 inches, sporting a gray finish that blends into the hearth floor. A standard 3/8-inch NPT male thread is machined at the inlet end, engineered to fit directly into the burner pipe receiving port of the Midwest Hearth Universal Log Lighter air mixer.

Installation considerations focus primarily on thread matching and clearance. Because this pipe handles combustible gas, proper alignment, heat-resistant gas-rated thread sealant, and leak checks are vital during setup. Homeowners should consult the original log lighter manual and follow all applicable local mechanical or plumbing codes. If you are uncertain about working with gas pipe fittings or verifying burner orientation under your grate, consulting a qualified gas service technician or chimney professional is strongly advised.

Buyers must keep in mind that this product is strictly a replacement pipe. It does not include an air mixer, mounting brackets, gas line fittings, or a manual gas valve. Furthermore, compatibility is explicitly specified for the Midwest Hearth Universal Log Lighter air mixer assembly, so it should not be assumed to fit proprietary or differently sized log lighter fixtures from other manufacturers without verifying the 3/8-inch NPT thread and physical clearances.

For fireplace owners looking to refresh a corroded or damaged burner in an existing compatible log lighter, this Midwest Hearth 17-inch pipe offers a targeted, cost-effective solution. As long as your firebox has sufficient width for a 17-inch tube and your air mixer accepts a 3/8-inch NPT connection, this low carbon steel replacement can help restore dependable firewood ignition for seasons to come.

This replacement burner tube is specifically designed to fit the Midwest Hearth Universal Log Lighter with Air Mixer.

The pipe features a standard 3/8-inch NPT threaded end that matches the burner port on the compatible air mixer. Verify your existing air mixer connection size before purchase, as proprietary log lighters from other brands may utilize different thread diameters or configurations.

The burner tube measures 17 inches in total length, with published dimensions of 17 by 1 by 2 inches.

Before ordering, measure the width beneath your fireplace grate and the clearance across your firebox floor to ensure the 17-inch pipe will rest securely in place without contacting masonry walls or obstructing ash cleanout doors.

Constructed from low carbon steel with 0.05 to 0.30 percent carbon content, this tube provides structural toughness suited for fireplace environments.

The heavy-duty steel build is intended to withstand repeated thermal cycling beneath active wood fires while offering an economical replacement alternative to purchasing an entire log lighter kit.

The Midwest Hearth Gas Log Lighter is designed specifically for homeowners with traditional wood-burning fireplaces that are plumbed for natural gas. Rather than relying on kindling, paper, or chemical fire starter blocks, this burner pipe sits under your fireplace grate to deliver a direct flame to the firewood. It is engineered solely as an ignition tool to establish a wood fire, functioning as a practical replacement for corroded starter bars or as a new addition to an existing natural gas firebox line.

Crafted from heavy iron pipe, the assembly is built to withstand high temperatures, falling embers, and heavy wood loads directly above it. The kit measures 19.5 inches in total length, combining a 17-inch perforated burner tube with a 2.5-inch air mixer. The burner connects via 3/8-inch threads to the air mixing chamber, while the primary fuel intake features a standard 1/2-inch NPT female thread to connect with standard residential gas supply lines.

A key operational feature is the integrated air shutter on the mixing chamber. This adjustable shutter allows you to fine-tune the ratio of oxygen to natural gas before combustion, producing a sharp blue flame that quickly transfers heat to seasoned firewood. Proper adjustment helps prevent excessive yellow flames or soot buildup on the burner during the initial firing phase, ensuring reliable wood ignition when fuel pressure is properly regulated.

Installation flexibility is supported through a convertible intake design. By positioning the included mixer plug, you can configure the inlet for either a straight feed or a 90-degree angled entry, accommodating gas stubs that enter from either the floor or the rear of the firebox. Keep in mind that a listed gas shutoff valve is not included in the package and must be installed upstream in the gas line. Because this involves tapping into combustible gas supplies, installation by a qualified professional is recommended to verify tight fittings and adhere to local building codes.

Proper use requires understanding the specific operational purpose of this product. It is strictly a starter bar, not a decorative gas burner or a secondary room heater. Once the firewood is actively burning, the gas supply must be shut off completely and the key removed to prevent unintended gas flow. For homeowners with an existing gas line in their wood hearth who want an uncomplicated, durable lighting system, this heavy iron kit provides a practical, straightforward solution.

This log starter kit accommodates different firebox configurations using an included mixer plug. Depending on whether your gas supply stub enters through the floor or through the side or rear wall, the air mixer can be set up in a straight line or as a 90-degree elbow connection.

All threaded connections should be properly sealed with pipe compound rated for natural gas. An approved, listed manual key valve must be installed upstream in an accessible location outside the firebox to regulate gas flow, as the kit does not include an integrated shutoff mechanism.

This device is intended exclusively for igniting natural wood fires. It should never be operated as a decorative burner, continuous gas log appliance, or standalone heating source. Operating the gas flame continuously under an empty hearth or without wood can cause excessive heat concentration and fuel waste.

Once firewood is stacked on an elevated grate above the burner, open the damper, light the burner according to standard gas lighting procedures, and monitor the logs until they catch fire. As soon as the wood fire is self-sustaining, shut off the gas valve completely and store the valve key in a secure location.
