= 1.5FT (0.5m)+ 5FT (1.5m) = 6.5 FT (2m)
H

= 1 FT (0.3m)

= 1FT (0.3m) + 1FT (0.3m) + 10.75FT (3.3m) = 12.75FT (3.9m)
H
O
= .03 (four 90° elbows + one 45° elbow - 90°)
= .03 (360° + 45° - 90°) = 6.75 FT (2.1m)

= 19.5FT (5.9m) + 6.5FT (2m) = 26 FT (7.9m)
Formula 1:

T
3 V
T
= 3FT (0.9m) x 6.5FT (2m) = 19.5FT (5.9m)
19.5FT (5.9m) = 19.5FT (5.9m)
Formula 2:
H
T
+ V
T
< 40 FT (12.2m)
26 FT (7.9m) < 40 FT (12.2m)
Since both formulas are met, this vent configuration is acceptable.
3.11 REAR EXIT
A. From inside the fi rebox, start by removing the top defl ector. Next, insert the 4" (102mm) fl ue pipe /
gasket assembly out through the rear of the fi rebox. Secure the assembly to
the rear and top of the appliance using 4 #8 x ¾" screws supplied. Do not
overtighten. The gasket should seat evenly against the rear and top of the
fi rebox, creating an air tight seal.
B. Re-install the top defl ector.
C. Before attaching an elbow or rigid adaptor to the rear collar, it may be
necessary to trim the 4" (102mm) collar.
