3 Sidewall direct venting
Sidewall termination – optional concentric vent
Multiventing sidewall terminations
When two (2) or more direct vent appliances are vented near
each other, each appliance must be individually vented (see
FIG. 3-13). NEVER common vent or breach vent this appliance.
When two (2) or more direct vent appliances are vented near
each other, two (2) vent terminations may be installed as shown
in FIG. 3-13. The vent terminations must be at least 36 inches
away from the first two (2) terminations. It is important that
vent terminations be made as shown to avoid recirculation of
flue gases. Dimension A in FIG. 3-13 represents the distance
between pipes or rain shields, as touching or a 2 inch maximum
separation.

DO NOT use field-supplied couplings to
extend pipes. Airflow restriction will
occur and may cause intermittent
operation.
9. Cement appliance combustion air and vent pipes to the
concentric vent termination assembly. See FIG. 3-12 for
proper pipe attachment.
10. Operate the appliance one (1) heat cycle to ensure
combustion air and vent pipes are properly connected
