The door may need to be adjusted to
be completely airtight. The gaskets’
air-tightness can be adjusted using the
adjustment screw located on the right
side of the fireplace façade. (An Allen
key #1/8 – not supplied - will be
necessary for this adjustment)

3.3.10 Glass Care - Replacement
The glass used for the BIS ULTIMA 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. 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 is designed to keep the glass clean under normal operating conditions. If
the BIS ULTIMA 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.
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:
Gasket Length Dimensions
Around glass 69" 5/16" dia.
On door frame 73" 5/8" dia.
