The heat output of portable patio heaters can vary greatly, and so will the minimum clearance to safely operate them. The following is only a basic guide to quickly assist you. Consult your owner’s manual thoroughly before installing your portable patio heater. For portable patio heater units between 35,000 and 50,000 BTUs, provide at least 30 inches of clearance above and on all sides of the reflector and emitter head from combustible materials. Do not have anything combustible closer than 36 inches directly under the emitter head. Smaller units from 10,000 to 35,000 BTUs need at least 24 inches of clearance above and on all sides of the reflector and emitter head. Do not have anything combustible directly under the heat closer than 30 inches of a lower powered portable patio heater.
