Your new Harman Stove viewing door gasket has been
factory set, however over a period of time some minor
adjustment may be necessary. The easiest way to check the
adjustment of the door gasket is to take a small piece of paper
(when the stove is not burning) and open the door, place
the paper between the face of stove body and the gasket at
the top center of the door, close the door. You should have
a slight amount of resistance when you try to pull the paper
out. Repeat this process on the bottom center of the door. If
the paper is loose then some adjustment is necessary.
To adjust the door, the stove must be turned off and cold.
Open the door, loosen the 2 bolts shown (see Fig. 37) and
bump the latch adjuster (Fig. 38) toward the back of stove,
snug bolts and test for proper seal as described above. Once
the proper seal is attained, open the door and finish tightening
the bolts. If proper adjustment cannot be accomplished, then
a new gasket should be installed.
Over a period of time the gasket will wear and a new gasket
will have to be installed. To install a new gasket you must
remove the old gasket. After the gasket is removed the
gasket channel should be free of all loose particles. The
gasket cement used to hold the gasket in place is RTV (HIGH
TEMPERATURE) silicone. Put a bead of RTV silicone in the
bottom of the gasket channel, then install the new gasket and
close the door. Allow to dry for several hours before lighting
the stove. After the RTV silicone has cured, the door will have
to be adjusted for proper sealing. If you have just replaced
the door gasket, the latch adjuster must be pulled towards
the front of the stove. Follow the procedure mentioned above.
