Can I use my Heat Hog both indoors and outdoors?
Yes, but proper ventilation is required for safe usage, as it is an unvented gas-fired heater. The heater uses air (oxygen) from the area in which the heater is used. Adequate combustion and ventilation air must be provided. The Heat Hog does have a safety Oxygen Depletion Sensor (ODS) to keep you safe but you must follow the instructions as outlined in the Heat Hog owners’ manual.
In Massachusetts and Canada, unvented heaters are prohibited from use indoors according, to law.
