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 two 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 a fresh air intake from the wall to the back of the pedestal
B) Installation of a fresh air intake from the floor to the base 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 outside air intake
system 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.
