We highly recommend dust covers for catalytic heaters. Fitted dust cover protects your Olympian Wave catalytic heater when it is not in use. When dust or other contaminates accumulate on the heater, it can significantly shorten the life of the heater. It also creates an atmosphere where the heater creates chemical byproducts other than water and carbon dioxide. Choose the correct cover for your heater size and also for the way you are mounting your heater (wall-mount or free standing). Available only in black.
