Pinnacle & Stardance Direct Vent - Rear Vent Gas Heaters

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.
