The preheated air mixes with wood gases to create a clean burn ensuring optimal efficiency from your stove. If they are damaged, cracked or deteriorating in any way, they should be replaced.
Installation tips: Place a screwdriver (any style except flat head) into one of the air holes and tap it with a hammer/mallet to the left until the right end of the tube is freed. To install a secondary air tube, reverse the above instructions.
IMPORTANT: All secondary air tubes must be in place for proper operation. Highlighted in yellow in product image.
