Rear Exit - Napoleon B46NTR Installation And Operating Instructions Manual

Example:
V
= 1.5 FT (0.5m)
1
V = 5 FT (1.5m)
2
V = V + V = 1.5FT (0.5m)+ 5FT (1.5m) = 6.5 FT (2m)
T 1 2
H = 1 FT (0.3m)
1
H
= 1 FT (0.3m)
2
H = 10.75 FT (3.3m)
3
H = H + H + H = 1FT (0.3m) + 1FT (0.3m) + 10.75FT (3.3m) = 12.75FT (3.9m)
R 1 2 3
H = .03 (four 90° elbows + one 45° elbow - 90°)
O
= .03 (360° + 45° - 90°) = 6.75 FT (2.1m)
H = H + H = 12.75FT (3.9m) + 6.75FT (2.1m) = 19.5 FT (5.9m)
T R O
H + V = 19.5FT (5.9m) + 6.5FT (2m) = 26 FT (7.9m)
T T
Formula 1:
H < 3 V
T T
3 V = 3FT (0.9m) x 6.5FT (2m) = 19.5FT (5.9m)
T
19.5FT (5.9m) = 19.5FT (5.9m)
Formula 2:
H + V < 40 FT (12.2m)
T T
26 FT (7.9m) < 40 FT (12.2m)
Since both formulas are met, this vent configuration is acceptable.
