Installation
When combustion air is taken from outside, you can bring it directly to the
pedestal or near the unit. In the second configuration we recommend that the
distance between the air intake and the pedestal does not exceed 5' (1.52 m).
Here are four typical methods to bring fresh air into the unit. Consult the owner's
manual of your appliance to determine which configuration applies to and suits
your installation. Only one method may apply to your unit.
A Installation of fresh air intake kit from the wall to the back of the
pedestal
B Installation of fresh air intake kit from the floor to the base of the
pedestal
C Installation of fresh air intake kit from the wall to the inside of the
pedestal
D Installation of fresh air intake kit from the floor to the inside of the
pedestal
Note:
When using configuration A or B: make sure that there
are no gaps between the pedestal base and the flooring.
If any, they should be sealed with extra insulation. This
is especially important with models where the pedestal
flanges are open at the base of the pedestal, as shown
on this figure.
Periodically inspect the fresh air intake kit to make sure it is not obstructed. One
evident sign of air restriction or obstruction is to see smothering effect when
burning kindling with the door closed.
