SSEMBLY
The firebox requires periodic cleaning to prevent the
accumulation of dust, lint, and other debris. To clean
the firebox, set the thermostat to the "OFF" position,
and turn off the gas at the gas control valve. When
the unit is cool, open the front door, and remove the
front cast and glass assembly. Carefully remove the
decorative log set, taking care not to damage the
logs, refractory panels, or chip the enamel cast iron.
Clean the firebox, refractory panels, and TEK burner,
and carefully vacuum the entire surface of the log
set. Thoroughly vacuum the ports (holes) along the
top of the TEK burner, and the pilot assembly.
With the decorative logs out of the firebox, re-install
the glass assembly and front cast. Briefly light the
unit according to the lighting instructions described
on page 22. Check to insure a proper flame is
burning from each burner port. The pilot flame
should be large enough to engulf the thermopile and
thermocouple as shown in Figure 12.
• NOTE: Do not operate the unit for more than 1-
2 minutes without the log set in place. Turn the
unit off by setting the thermostat to "OFF", and
turning the gas control valve off. Allow the unit
to cool.
Check and clean any burner ports that are not
burning, or not burning properly. Clean burner ports
using a soft brush or vacuum cleaner. If the pilot
flame height needs adjustment, it should be
adjusted by qualified service personnel as described
on page 23.
Complete the cleaning procedure by carefully placing
the log set within the firebox as described on page
19. Re-install the glass assembly and front cast.
Turn on the gas, light the unit and check for proper
operation. Flame patterns should look similar to the
flames in Figure 13. Regularly check to insure the
area around the Tudor is kept free from combustible
materials, gasoline, and other flammable vapors and
liquids. Check that the flow of combustion and
ventilation air is not obstructed.

center of the glass frame. This will allow the
glass to free up from the steel.
4. Remove the existing gasket by grasping one end
and pulling firmly. Clean the remaining adhesive
on the glass off with warm soapy water. Let dry.
5. Determine the correct length of the appropriate-
sized gasket by wrapping it around in the glass.
Allow an extra 1 to 2" (25-50mm), and mark the
spot to be cut.
6. Cut the gasket at the marked spot with a utility
knife.
7. Starting at one end, pull the paper off the back
of the gasket and center the gasket over the
glass. Continue around the glass until you meet
up where you started. Do not overlap the gasket
ends or leave ends with ragged edges.
8. Firmly and evenly, press the gasket to seat it in
its channel.
9. Sandwich the glass within the glass frame and
glass gasket clip.

gasket clip to the glass frame
