CATALYST MONITORING
4.
Now that the combustor has been removed you’ll be able to see
one stainless bypass retainer on each side. These can remain in
place and do not need to be removed. These clips are not fixed in
position and can fall into the firebox. Make sure they are in position
before replacing the combustor. Using the same screwdriver or
pocket knife, scrape any old gasket from the surface areas of the
dome. The dome is the housing that surrounds the combustor. If
you clean your existing combustor, you’ll need to order replacement
combustor gasket. It is always a good idea to have a spare
combustor gasket on hand prior to performing any maintenance. If
you purchase a new combustor a new gasket will already be applied
to the combustor.
5.
This new combustor already has the gasket installed. Note
the 1” wide masking tape. This tape will help to keep the leading
edge of the gasket from snagging during installation. If you’ve
cleaned your combustor, wrap the combustor gasket as you see
here and use the 1” masking tape around the perimeter front and
rear. During the first fire the masking tape will burn off and the
combustor gasket will swell providing a tight seal. It is this tight
seal that improves efficiency and performance. You should never
burn your stove without a combustor gasket installed.
6.
Since the combustor is only 2” deep, there is ample room to lift
the new combustor into place.
REMEMBER TO HAVE THE TAB
ACROSS THE BOTTOM EDGE OF THE COMBUSTOR AS IT IS
INSTALLED
. Slowly push the combustor in at the top apply even
pressure to the left and right corners. This will allow for a better
view of the bottom edge for the final fitting.
DO NOT FORCE
THE COMBUSTOR INTO THE DOME. TAKE YOUR TIME AND
WORK IT INTO PLACE SLOWLY.
