Gasket Replacement
The Radiance Gas Heater uses 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.
83 & 84) 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 necessary.
. Determine the correct length of gasket by laying it out
around the edge of the glass. Allow an extra 1 - ” (5-
50mm). Mark the spot to be cut. Use a utility knife.
3. Starting on a long edge, remove about 6” of the protec-
tive 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. 85)
4. Apply a thin bead of high temperature sili-
cone 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 previously
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 they match Figure 86. The
flames will be blue during the first 15-0 minutes of opera-
tion, 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.
