Should I purchase a cover for my patio heater?

Covering your unit when not in use will keep your unit looking new by protecting it from the elements, and also keep dust, moisture and bugs out of the burner assembly. Please note that a cover can act like a sail if the wind catches it so use caution when leaving a covered heater unattended. Move the heater to an area protected from the wind or secure the heater to something immobile to keep the heater from blowing over.
