Alternate Chimney Configurations
Some installation configurations may require orienting the chimney flue through
the exterior wall, rather than the roof, or utilizing the top exhaust port of the heater,
rather than the side port. Please consult with Lanair for guidance in these cases.

It is always preferable to install the chimney flue through the roof in order to ensure
proper draft and minimize horizontal connectors that can collect debris and mois-
ture. If installing the chimney through an exterior wall, be sure to adhere to height,
clearance, and material requirements.

In most structures, using the side exhaust port of the heater makes it
easier to install the heater and maintain height and clearance require-
ments. If utilizing the top exhaust port, be sure to adhere to height,
clearance, and material requirements. If using the top port, the installed
cap must be removed and placed on the side port using the screws pro-
vided.
Vertical chimney must be a minimum of 10 feet in length to
establish proper draft
Horizontal chimney-connector length should be minimized
and maintain 1/4" rise per 1 foot of run

proper draft, consider lengthening the vertical chimney.
