There is a separate loading door for the ash pan and a small lighting hole. There is an adaptation available for the Chilli Billie making it suitable for smoke control areas. There are two variations of heat shield enclosures available for the Chilli Billie called Penguin Enclosures; the round enclosure and the square corner enclosure. The enclosure offers heat shielding, underneath, to the rear and both sides of the stoves. Parts of it are double skinned to allow for the movement of air. In addition the enclosure provides a bracket for the flue.
