9.5.2 If the chimney liner does not align with the insert’s flue outlet
You can install a liner offset adapter (AC01370), which is sold separately. Please note
that an offset adaptor reduces the free flow of exhaust gases and may result in smoke
roll-out from the insert when it’s door is opened for loading. Only use an offset adaptor if
a) there is no other alternative and b) if the total height of the fireplace and chimney is at
least 20 feet. If you must install a liner offset adapter, secure the three brackets with the
three screws provided (30131) on top of the insert in the three holes in front of the flue
outlet. The long end of the brackets must be attached to the insert. The brackets and
screws are in the insert’s owner’s manual kit. Then follow the instructions in the manual
provided with the liner offset adapter kit.
9.6
Minimum Chimney Height
The top of the chimney should be tall enough to be above the air turbulence caused when
wind blows against the house and its roof. The chimney must extend at least 1 m (3 ft.)
above the highest point of contact with the roof, and at least 60 cm (2 ft.) higher than any
roof line or obstacle within a horizontal distance of 3 m (10 ft.).
