CALCULATING THE TOTAL VERTICAL SECTION (TVS)
Calculate the Total Vertical Section by adding up all vertical upward sections in your specific vent design.
CALCULATING THE TOTAL HORIZONTAL SECTION (THS)
Calculate the Total Horizontal Section by adding up all horizontal sections in your specific vent design.
CONFIGURATION
BEWARE OF ELBOWS
Elbows do not help the movement of air through your venting configuration and must be included when determining your minimum
and maximum vent lengths.
45° elbows are calculated as either vertical or horizontal depending on positioning.
There are (2) types of elbows:
TYPE N
45° and 90° elbows from vertical to horizontal and vice versa
-The first (3) N elbows do not need to be included in venting calculations.
-For every extra N elbow, you must add 40”(1m) to your
THS
TYPE Q
45° and 90° elbows from horizontal to horizontal
-For each 90° elbow in the horizontal section you must add 80”(2m) to your
THS
-For each 45° elbow in the horizontal section you must add 40”(1m) to your
THS
INTERPRETING THE GRAPH RESULTS
Once you have found your total vertical section (
TVS
) and your total horizontal section (
THS
) determine where you vent
configuration will terminate on the corresponding venting chart (shown on the next page).
These venting numbers will correlate as follows:
If your venting configuration lands on a block with an “X” the configuration is not possible.
For venting configurations that land on an “X” a power vent option may be available.

INSTALLING A RESTRICTOR
Some vent configurations may require a restrictor plate be installed. The restrictor for this fireplace is installed on the inside top of
the fireplace and is to be slid open or closed. Loosen the screws on either side and slide the restrictor as desired. Do not modify the
restrictor(s). Please use the graph above to determine if you will need to use a restrictor.

Loosen these (2) Phillip’s head screws
to slide on/off the restrictor.
