Mr. Heater 200,000 BTU Big Maxx Natural Gas Unit Heater with NG to LP Conversion Kit
Description
The Mr. Heater Big Maxx 200,000 BTU Natural Gas Unit Heater turns unheated garages, workshops and barns into year-round workspaces with powerful, efficient forced-air heating. Designed for commercial and residential use, it delivers consistent warmth across up to 3,377 square feet, ideal for large spaces needing substantial heating. The high-velocity electric fan pulls cool air across the heat exchanger and distributes warmth evenly, while the design supports both vertical and horizontal venting for flexible installation. Its low-profile requires only 10-foot minimum ceiling clearance and 1-inch mounting space, fitting structures with height limits. Safety features include high-temperature shutdown, gas safety shut-off flame sensor, and electric spark ignition with self-diagnostic control for reliable operation. Configured for natural gas with an included propane conversion kit for fuel flexibility.
