The Big Buddy is a portable propane heater with a heat output of 4,000 to 18,000 BTU. It heats enclosed spaces such as cabins up to 450 square feet. It is approved for indoor and outdoor use, burns clean and is nearly 100 percent efficient.
It blends radiant heat with convection heat, using an integrated fan that increases its heating capacity. The fan has been removed on some Big Buddy (MH18B) models. A control knob sets low, medium or high heat. To light it, push and rotate the knob, and the built-in Piezo sparker does the rest.
The heater connects directly to two 1 lb. propane cylinders. Two swivel regulators let you switch to a remote gas supply by adding a single hose and filter. It shuts off automatically if it is tipped over, if the pilot light goes out, or if it detects low oxygen levels. At altitudes over 7,000 feet above sea level, the heater may shut off. Using unauthorized accessories or attachments with it is prohibited, may cause serious injury and voids the warranty.
