Gasket Replacement

The PDV20 and SDVR Gas Heaters use a ‘tadpole’ type gasket to seal between the glass panel and the frame. In time, this gasket can become brittle and compressed and should be replaced. New gasket is available from your dealer.

Shut off the gas supply and allow the stove to cool. Wear safety goggles and a dust mask.

1.Remove the Front, Glass Frame and Glass Panel. (Figs. 65, 66) Remove the old gasket. Use a razor blade to separate the glass and gasket from the frame, and to clean the glass of any remaining cement or bits of gasket. Use a cold chisel if neces- sary.

2.Determine the correct length of gasket by laying it out around the edge of the glass. Allow an extra 1 - 2” (25-50mm). Mark the spot to be cut. Use a utility knife.

3.Starting on a long edge, remove about 6” of the protective paper strip and apply the flat adhesive face of the gasket around the outside-facing edge of the panel. Continue around the panel, applying about 6” at a time and being careful to not stretch the material. Do not overlap the gasket ends. (Fig. 67)

4.Apply a thin bead of high temperature silicone rubber sealant along the inside corner of the glass frame, all around the perimeter. Place the flat gasketed side of the glass panel back into the steel frame. Pinch the rounded inside-facing gasket material to bulk it up.

5.Replace the glass frame and front panel as previ- ously described.

Inspect the Vent System Annually

Have the vent system inspected annually by a qualified technician. Shut off the main gas supply before inspect- ing the system. Both the inner exhaust pipe and the outer combustion supply pipe must be checked to confirm that they are unblocked and in good condition.

Check the Gas Flame Regularly

To ensure that the stove is operating properly, check the flames periodically to confirm that they match Figures 50-52. The flames will be blue during the first 15-20 minutes of operation, and will gradually turn to yellow after that.

Do not use your stove if the flame pattern differs from that shown here. Contact your Vermont Castings dealer or a qualified technician for help.
