3.6 OUTSIDE AIR KIT
The installation of an outside air assembly is required on the BIS PANORAMA.
The outside air assembly must be installed according to the following requirements:
1. Duct length should be kept to a minimum. The maximum length of a 4" I.D. (100mm)
insulated flexible duct is 20 ft. (6.1 m). The duct can be extended to a maximum of 40
ft. (12 m) using a 6" I.D. (150mm) insulated flexible duct.
2. The air intake register must not be installed more than 10 ft. (3050 mm) above the
base of the fireplace.
3. The fresh air must come from outside the house. The air intake must not draw air
from the attic, from the basement or garage.
4. The air intake register should be installed where it is not likely to be blocked by snow
or exposed to extreme wind and well away from automobile exhaust fumes, gas meters
and other vents.
5. The duct and register may be installed above or below floor level.
3.6.1 Outside Air Installation
Make a 4 _" (110 mm) hole in the outside wall of the house at the chosen location. From
outside, place the outside air register in the hole (open side down) and fasten the register
to the wall, with screws as shown (see figure 22). Slip the pipe into the insulated sleeve.
Place the insulated pipe over the register tube and over the fireplace’s outside air
connector (see figure 23). At each end, carefully pull back the insulation and plastic cover
exposing the flexible pipe. Using the aluminium tape provided, wrap the tape around the
joint between the flexible pipe and the air inlets. Carefully push the insulation and plastic
cover back over the pipe. Using aluminium tape, fasten the plastic cover in place.
