GLASS REPLACEMENT
The glass used in Country Flame fireplace doors is a 1400 degree Fahrenheit (°F) high
temperature ceramic glass. If the glass should crack or break for any reason, it must be
replaced with an equal or better grade ceramic glass. The use of tempered glass or ordinary
glass IS NOT AUTHORIZED. The use of such unauthorized glass would create a hazardous
situation. Fireplace door replacement glass can be purchased from Country Flame or any
authorized dealer. See FIGURE 5 for securing points for the door glass. Refer to the following
sections for additional information on how to replace glass in a fireplace door.
GLASS-CERAMIC SPECIFICATIONS
KERA LITE ® glass-ceramic is specially manufactured for use in high temperature
applications. This glass-ceramic has a thermal endurance far exceeding that of normal
tempered glass. KERA LITE
® is designed to operate at temperatures ranging from -400 0 F to
+1400 0 F. Despite its superior thermal properties, KERA LITE ® stove windows should be
treated with care. This glass-ceramic can still be scratched or broken by mechanical abuse. When
cleaning the window, use only non-caustic, non-abrasive cleaners. Country Flame fireplace doors
use a KERA LITE
® glass-ceramic that is 0.197 inches thick +/- 0.008 inches. Country Flame
custom cuts each KERA LITE ® glass at its factory to fit the fireplace door. If problems occur or
should the glass-ceramic ever need replacement, contact Country Flame or a local authorized dealer
for assistance. The glass-ceramic specifications are as follows:
Manufacturer Euro Kera
Window Type Glass-Ceramic, Kera Lite ®
CAUTION: Do not attempt to clean hot glass. Do not strike, abuse, slam shut, or operate the
fireplace door system with any broken glass-ceramic in a fireplace door.
DO NOT use abrasives such as steel wool or powder abrasives as they will permanently damage
the glass. Once the glass has been scratched, complete replacement of the glass will be required.
Use only approved 1400 degree Fahrenheit (°F) high temperature stove ceramic glass to replace
any cracked or broken glass.
GLASS or GASKET REPLACEMENT
Remove the left and right door, whichever one needs repair, from the door frame. Place the
door to be repaired face down on a protective surface to ensure no marring or scratching
occurs during glass or gasket replacement. FIGURE 5 shows the glass clips, the glass, the
gasket on the glass, and the door gasket. Ensure, if removing glass, that all screws and glass
clips are stored in a safe place. These items will be needed when the glass is reinstalled. Any
screws or clips that are damaged should be replaced in order to make their removal easier the next
time repairs are completed. If new glass is ordered from Country Flame it will also require glass
tape.
To replace the Thermoglass
™ knitted rope and tape gasket, first remove all of the old material and
gasket cement. Use a putty knife or other sharp instrument to assist in removal. Use caution to
prevent injury when removing old material. It is important to ensure the doorframe area is totally
clean before installing the new gasket cement and material. The door gasket must fit tight against
the inside track of the door to ensure an airtight seal when the stove door is closed. Apply gasket
cement to the gasket channel per instructions provided with the gasket kit. Once the cement has
been properly applied, install the new gasket. Both gasket and gasket cement are available from
Country Flame or an authorized dealer. Information on the next page defines the recommended
gasket material to use in a specific Country Flame Fireplace Door Systems.
