Radiance Direct Vent Gas Heater
20012697
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. 76 & 77) 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. 78)
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 quali-
fied technician. Shut off the main gas supply before
inspecting 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 79.
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.
