How do I replace the light bulb in the heater?

Unplug the stove and remove the screws holding the stove back panel in place. Unscrew the 3 screws holding the baffle and remove it carefully. Remove the light bulb and replace it with a clear, 40-watt, E12 socket base light bulb (candelabra base, B bulb), then reverse the steps to reinstall the baffle and back panel.
