3.5 HOT AIR DUCTING INSTALLATION
Different hot air ducting systems can be installed with the BIS PANORAMA:
- Gravity kit
- Forced air kit (Not EPA approved) (p. 21)
3.5.1 Gravity Kit
Part List (7B30ZK-1)
(See Figure 16)
- 2 telescopic lengths 8" I.D.
- 2 90º elbows 8" I.D.
- 2 hot air outlet kits
(louvers and frames)
- 2 adaptors
See components list page 36.
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 (BPCF) 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 figure 17
*
The height of the louver must be measured from the base of the BIS to the
middle point of the louver.
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 17).
WARNING: both pipes of the gravity kit must be installed. Any other installation may
cause fire and void warranty.
