NOTE : To install the single hot air outlet, in conjunction with AC chimney,
the chimney must be offset towards the back using 2 – 30 deg. elbows back to back
on the fireplace.
The only fan that can be used with the gravity kit is the UZY5
The gravity kit allows you to block the upper grill of the fireplace. To do so, follow the
steps below:
a) Remove the upper grill and its frame from the fireplace.
b) Install the panel for clean face option (BISCF) making sure that the insulation strip is
installed inside.
c) The fireplace façade can be covered with non-combustible material (fig. 18).
The safety rules for hot air ducting gravity kit installations are the following:
Minimum height
*
68" (1727 mm)
Maximum length See figures 16 & 17
*
The height of the louver must be measured from the base of the BIS to the
middle point of the louver.
The single outlet system is designed to be installed either flush with the front of the BIS
ULTRA or extended out slightly from the face of the fireplace (if installing with a brick or
thick facing for example). To extend the double outlet system, it will be necessary to
purchase two adjustable lengths (7B26ZL2A). To extend the single outlet, it is necessary
to install the insulation strip provided with the system. A maximum of 3 _ ".(89 mm) of
extension is provided by the single outlet system (see figure 17).
When installing the double outlet system, the hot air outlets can be installed in the same
room as the fireplace, or one or both of the outlets can be installed in adjacent or upper
rooms. Installing the ducts at different elevations will tend to exhaust more heat out of
the higher outlet (figure 16).
