Vermont Casting 2170 Repair Missing Cement in Seams, Avoid Damaging the Glass Door Panel, 2006063

5.Test the gasket by closing the door on a slip of paper as described above. Adjust the gasket in any areas where an inadequate seal is evident.

All rope-type gasketing used in the Seneca is made of fiberglass. The gasket size for the front, side and ash doors, as well as for the top and inner top, is 3/8Ó diameter. The front door glass is sealed with a 3/16Ó gasket, while the flue collar employs a 1/4Ó size. Two small pieces of 1/4Ó wire gaskets are used inside the Seneca between the grate seals and the left side plate, and a special Interam¨ gasket wraps around the combustor to provide a seal.

Repair Missing Cement in Seams

The cement in the stove seams may deteriorate over time and fall out in places. Just as with the stove doors, it is necessary to keep the seam seals in good condition. Spot-fix with furnace cement (available from your local dealer) any areas where the cement seal is visibly deteriorated. Allow 24 hours for the new cement to dry after "washing down" seams.

Avoid Damaging the Glass Door Panel

Do not abuse the glass by slamming the door or striking the glass with a log. Never operate your stove if it has damaged or broken glass. If you need to replace the glass, use only replacement glass provided by your local Seneca dealer.

Replace Broken Glass Immediately

Prepare to replace the glass in your stove by first clearing a large flat area nearby to use as a work surface. Place in order the pieces that you disas- semble. This will be a great help when you put the pieces back together.

To remove the glass:

1.Open the front door. Lift the door gently while raising the end nearest you slightly. This will cause the bottom hinge pin to leave its seat. Once the bottom hinge pin is free, lower the door to free the top hinge pin. Place the door face down on a padded surface.

2.Remove the four #10 screws holding the stainless steel glass retaining clips on the left and right sides of the glass. Remove the clips, and lift the glass off the brass frame. Lift broken glass carefully to avoid being cut.

3.Remove the old gasket.

Fig. 31 In order of assembly, the front door glass compo- nents include a brass frame, gasket, glass, two clips and four screws.

To install the new glass:

1.Place a new piece of 3/16Ó gasket around the perimeter of the brass frame for the glass to rest on, as far to the outside as possible.

2.Place the new piece of glass on the gasket.

3.Position the glass retainer clips, and fasten in place with the #10 screws previously removed. Tighten the screws alternately.

Damper Adjustment

Check the damper to confirm that it is locking tightly whenever the top is removed for combustor inspection. If the damper needs adjustment, use a 7/16Ó socket wrench with a socket extension and follow this proce- dure:

1.Open the damper.

2.If necessary for better access, carefully remove the refractory cover.

3.Loosen the adjusting boltÕs lock nut.

4.Loosen the anchor boltÕs lock nut (it is located on the back side of the griddle and is accessible inside the stove through the front door).

5.Loosen the anchor bolt a turn or two.

6.Test the damper mechanism. If further adjustment is necessary, continue to tighten the adjusting bolt until the damper closes snugly.

7.When final adjustment has been made, tighten the adjusting bolt lock nut.

8.Carefully replace the refractory cover if it was removed.

9.Replace the top.

10.Alternately tighten the two bolts that secure it.
