Draw the seating area
Record where people sit, what covers the area and where a heater could be mounted. Use that sketch when asking the manufacturer about the intended location. Source: editorial
Ask for outdoor instructions
Require model-specific documentation for outdoor use and weather exposure. Do not treat a generic heater description as permission to use it outdoors. Source: editorial
Keep the heat path in mind
