Goodman B4022700 3" In-Shot Burner

The Goodman B4022700 is a genuine OEM 3-inch in-shot burner engineered for Goodman GMTH045-3 gas furnaces. In-shot burners deliver the fuel-air mixture into the heat exchanger tubes for clean, quiet, and efficient combustion. Over time burners can rust, warp, or clog with debris, causing rough ignition, delayed lighting, or a rollout condition — replacing them restores safe, even flame across every tube.

Specifications

Part Number: B4022700
Type: In-shot (monoport) gas burner
Length: 3 inches
Material: Corrosion-resistant coated steel
Fits: Goodman GMTH045-3 gas furnaces
Brand: Goodman (OEM)

OEM vs. Generic

Genuine Goodman burners are matched to the furnace's manifold pressure and orifice sizing, ensuring the flame carries over correctly from tube to tube. Generic burners may have slightly different venturi geometry, leading to noisy ignition or uneven heating. For proper flame characteristics, OEM is strongly recommended. Replace all burners as a set for uniform performance.

Installation Difficulty

Moderate (2/5) — Shut off gas and power, remove the burner assembly bracket, slide out the old burner, and install the replacement aligned with its orifice. Roughly 20–30 minutes. Verify flame carryover and check for gas leaks after service; when in doubt use a licensed HVAC technician.

Compatible with Goodman GMTH045-3. Confirm your model before ordering.
