Locate the vent and combustion air termination using the
following guidelines:
1. The total length of the vent or combustion air piping
must not exceed the limits given in Table 1 on page 13.
2. The concentric vent/air termination assembly must
be installed 12 inches above grade or projected
snowline as shown in Fig. 4
WARNING
NOTICE
3. The vent and combustion air piping connected to the
concentric vent/air termination assembly must com-
ply with the instructions listed in this supplement.

4. The following should be considered when determin-
ing the location of the vent and combustion air ter-
mination:
a. Locate the vent termination where flue vapors
will not damage surrounding shrubs, plants or
air conditioning equipment or be objectionable
to the homeowner.
b. The flue products will form a noticeable plume
as they condense in colder air. Avoid terminat-
ing the vent in areas where the plume could
obstruct window views.
c. Prevailing winds could cause freezing of flue
condensation and a buildup of water / ice on
surrounding plants, building surfaces or com-
bustion air inlet.
