Door Gaskets
The firebox door gasket and the oven door gasket should be smoke-tight.
To stop smoke leaks, you may need to shim the hinge side, the latch side, or
both. You may also need to “thicken” the gasketing by using additional
(allow 4 hours to cure before closing the door) RTV silicone between the
gasket and the body of the unit. Paper check the gasket seal by placing a
long strip of paper between the gasket and the unit body so that the paper
extends outside the door. Close and latch the door. Pull the paper toward
you. It should be very resistant to your effort. If it seems loose, further
adjust the door or the gasket thickness.

Inspect the interior of the firebox. Repair as required any damaged
refractory.
Inspect and lubricate as needed the damper linkages.
Inspect and lubricate the combustion air linkages. Clean the combustion
air damper (14), and the combustion air inlet elbow (13B). Inspect the
combustion air damper gasket (13C).
Remove the roof cover. Clean carbon from top components. Remove the
cover (20A) over the fresh air damper (20). Inspect, clean and repair/replace
as needed the fresh air inlet damper (20) and gasket.
Inside the oven, remove the convection cowling (25) by removing the two
“T” bolts (25A) and lifting the cowling off the rear clips. Then remove the
EVAC outlet baffles (28), the oven heat outlet baffle (29), and the oven heat
inlet baffle (30). Inspect and clean all areas behind these parts. Reinstall
the parts.
Remove the rear upper exterior skin panel. Remove the bolts that secure
the hinged access cover (22) over the rear dampers and open the cover. For
older models remove the rear EVAC and Flue access plate and the rear
firebox damper access plate. Clean all the exposed cavities. Inspect and
clean, as needed, the flue beneath the firebox bypass damper (19). To
inspect this flue the damper will have to be in the open position. Either turn
the unit to the EVAC setting or disconnect the firebox damper linkage and
reconnect after inspection. Inspect and repair/replace as needed the
damper gaskets associated with the EVAC dampers (17), the flue damper
(18), and the firebox damper.
ANNUALLY:
The interior fan cowling area should be cleaned. Remove the convection
cowling (25), clean, and reinstall. Clean the convection fan impeller (26) at
the same time.
