VERTICAL VENT SYSTEM CLEARANCES

ALL APPROVED RIGID PIPE
KOZY HEAT #800 SERIES
VERTICAL TERMINATIONS
MINIMUM: 45˚ elbow + 2 ft. (610 mm) + termination cap.
MAXIMUM: 45˚ elbow + 30 ft. (9.14 m) + termination cap.

COMBUSTION AIR INTAKE SETTINGS

VERTICAL TERMINATION HEIGHT
0 - 10 ft. (0 - 3.05 m )
11 - 20 ft. (3.35 m - 6.10 m)
21 - 30 ft. (6.40 m - 9.14 m )
25 - 30 ft. (7.62 m - 9.14 m)
RESTRICTOR
A restrictor is included in fireplace components packet.
Each installation is unique and affected by various factors including venting configuration, altitude and climate. Therefore, after
fireplace installation is complete a restrictor may be required or may need to be removed or modified.
Please refer to page 25 for installation instructions if installing the restrictor in conjunction with the venting.
Page 50 has information on restrictor recommendations depending on burner flame appearance and instructions on installation after
venting is completed.
HORIZONTAL & VERTICAL COMBINATION TERMINATIONS
MAXIMUM: 10 ft. (3.05) horizontal + 15 ft. (4.57 m) vertical + cap. 25 ft (7.62m) total.
ELBOWS
For each additional 90° elbow used after the first elbow, 3 ft. (914 mm) must be subtracted from the maximum allowed venting. For
each 45° elbow used, 1-1/2 ft. (457 mm) must be subtracted from the maximum venting allowed.
NOTE: (2) 45° degree elbows may be used in place of (1) 90° elbow.
IMPORTANT: THE HORIZONTAL VENT HEAT SHIELD MUST BE INSTALLED WHEN USING A 45-DEGREE ELBOW DIRECTLY
OFF FIREPLACE TO HORIZONTALLY POSITION THE VENT SYSTEM. EXCEPTION: CORNER INSTALLATIONS
THE KOZY HEAT WALL PASS-THRU, PART #800-WPT (4-1/2" (114 mm) - 6-1/2" (165 mm) WALL THICKNESS) OR #800-WPT2 (6-1/2" (165
