3.3.10 Glass Care - Replacement
The glass used for the BIS ULTIMA™ fireplace is a high temperature ceramic glass (1400°
F). If the glass breaks, it must be replaced with an identical ceramic glass. Tempered glass
or ordinary glass will not withstand the high temperatures of the BIS ULTIMA fireplace.
Replacement glass should be purchased from a Security Chimneys International dealer (see
“Replacement Parts”, page 34). Do not operate the unit with cracked or broken glass.
3.3.11 Glass Care - Cleaning
The BIS ULTIMA fireplace is designed to keep the glass clean under normal operating
conditions. If the BIS ULTIMA fireplace is operated continuously with the combustion air
controls closed, the glass will tend to get dirty unless the fuel, firebox and glass are
maintained at hot temperatures (see "Refuelling for best performance”). To clean the glass,
there are a number of specially designed cleaners. Your authorized Security dealer can
recommend a suitable cleaner which is available in your area. Regular household glass
cleaners will not clean creosote. Do not use abrasives such as steel pads, steel wool or oven
cleaner as they will scratch the glass.
DO NOT USE CHEMICAL GLASS CLEANERS ON PAINTED SURFACES AS IT MAY
CAUSE THE PAINT TO PEEL.
CAUTION:
Do not allow window cleaner to get in contact with door gasket or paint on the
facade. Once closed, contact of glass cleaner with the fireplace facade can provoke paint
peeling off.
3.3.12 Gasket Replacement
Remove the door from the unit (see page 10) and lay them on a clean unabrasive surface. To
replace the gasket, first remove all of the old gasket and gasket cement. Make sure that the
surface is totally clean before applying new cement (a high temperature silicone caulking
rated at 500°F, 260°C, is suitable) or adhesion problems may result. Apply gasket cement to
the gasket channel and install the new gasket. This replacement part is available from your
Security dealer in the following dimensions:
