Radiance Direct Vent /Natural Vent Gas Heater
20004188
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. 62 & 63) 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 pro-
tective paper strip and apply the flat adhesive face 
of the gasket around the outside-facing edge of the 
panel. Continue around the panel, applying a bout 6” 
at a time and being careful to not stretch the mate-
rial. Do not overlap the gasket ends. (Fig. 66)
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 mate-
rial 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 that they match 
Figure 67. 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.
