REPLACEMENT PARTS AND REMOVAL INSTRUCTIONS
(Continued)
Removing and Replacing the Secondary Air Tube
The secondary air tube is a tube with holes in it that runs along the top of the firebox near the front. Over
time it may wear and become ineffective. The secondary air tube should be replaced if it cracks or shows
severe deterioration, because it supplies air into the firebox that allows for a more efficient fire. The parts
needed to replace the secondary air tube are available from your dealer.
To remove the
secondary air tube, first
remove the two pins
located on the right side
of the firebox that hold
the tube in place.
These pins are
removed by using a
screwdriver or needle-
nose pliers to pry them
out of their holes. The
pins are held in place
by flanges on the pins
that expand once they
are pushed into the
hole. Therefore, you
may have to pry with
some amount of force
when trying to remove
them.

Short Tube that is
welded to the side
of the firebox
One pin holds the secondary air tube to a collar while the other pin holds the collar to a short tube welded
to the side of the firebox. Once both pins are removed, the collar can be slid to the left and the secondary
air tube and collar can be pulled down and away from the left side. To replace the secondary air tube,
place the collar on the secondary air tube, insert the secondary air tube into the hole on the left side of the
firebox, and slide the collar over to the right so it slides over the short tube that is welded to the right side
of the firebox. Then line up the secondary air tube and collar so the holes for the pins line up and insert
both new pins that are included with the replacement air tube kit.
