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

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

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.

NOTE: A #42 orifi ce was supplied with your appliance. In installations with a vertical rise greater than
8" (203mm) in the vent confi guration, the #42 orifi ce must be used to increase the fl ame size.
