5.1.6.1 Replacing the door glass gasket
The gasket must be centred on the edge of the glass. To do this easily, peel back a section of the paper
covering the adhesive and place the gasket on a table with the adhesive side up. Stick the end of the gasket
to the middle of one edge, then press the edge of the glass down onto the gasket, taking care that it is
perfectly centred on the gasket. Peel off more of the backing and rotate the glass and press the next section
onto the gasket. Do not stretch the gasket as you place it. Continue until you get to the start and trim the
gasket to length. Now pinch the gasket to the glass in a U shape, all around the glass. Reinstall the glass,
being careful to centre the glass carefully in the door. Do not over-tighten the screws. Note that the two
main causes of broken door glass are uneven placement in the door and over-tightening of retaining
screws.
Location Length Dimension
Around glass 66" (168 cm) “U” shaped
Do not abuse the glass door by striking or slamming shut. Do not use the fireplace if the glass is broken. To
change the glass, perform the same operation described above.
5.1.7 Cleaning and painting the fireplace
Do not attempt to clean or paint the fireplace when the unit is hot. Painted surfaces can be wiped down
with a damp cloth. Plated surfaces may be scratched by abrasive cleaners. To maintain the finish at its
original brilliance, use only a damp soft cloth to clean plated surfaces.
If the paint becomes scratched or damaged, you can give your wood fireplace a brand new look by
repainting it with heat-resistant paint. Before painting, roughen the surface with fine sand paper, wipe it
down to remove dust, and apply two thin coats of paint. For best results, use the same paint that was
originally used on the fireplace, which is available in spray cans. See your dealer for details.
5.2 Chimney and chimney liner maintenance
5.2.1 Why chimney cleaning is necessary
Wood smoke can condense inside the chimney liner and chimney, forming a combustible deposit called
creosote. If creosote is allowed to build up in the venting system it can ignite when a hot fire is burned in
the fireplace and a very hot fire can progress to the top of the chimney. Severe chimney fires can damage
even the best chimneys. Smouldering, smoky fires can quickly cause a thick layer of creosote to form. When
you avoid smouldering so the exhaust from the chimney is mostly clear, creosote builds up more slowly.
Your new fireplace has the right characteristics to help you to burn clean fires with little or no smoke,
resulting in less creosote in the chimney.
