Terminations
• ALL VENTING MUST TERMINATE (END)
WITHIN ONE OF THE DESIGNATED AREAS.
• SET STOVE EXHAUST RESTRICTOR TO THE
POSITION THAT CORRESPONDS TO THE
VENT TERMINATION AREA IN THE MATRIX.
When termination is exactly on a division line,
use the less restrictive position. For example,
if termination is 10 feet high and offset 7 feet,
restriction should be set at Position B.
• Up to two 45° elbows or one additional 90° elbow is
permitted in addition to the first elbow, however, a 5
foot reduction in horizontal length must be made for
each
additional elbow whether 45° or 90°.
