= 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)

H
= 1 FT (0.3m)

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)

H
= .03 (three 90° elbows + one 45° elbow - 90°)
O
= .03 (270° + 45° - 90°) = 6.75 FT (2.1m)
H
= H
+ H
= 12.75FT (3.9m) + 6.75FT (2.1m) = 19.5 FT (5.9m)

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.

REAR EXIT
FAILURE TO CREATE A SEAL TO THE FIREBOX WITH THE EXHAUST COLLAR ASSEMBLY WILL CAUSE
THE APPLIANCE TO FUNCTION IMPROPERLY AND CAN CAUSE INJURY OR PROPERTY DAMAGE.
Remove the safety screen and glass front, refer
A.
to " SAFETY SCREEN / DOOR REMOVAL AND
INSTALLATION" section.
Remove the contents from the firebox and set aside, you
B.
will need the exhaust flue collar from the top of the log
carton.
To ease assembly, remove the four hex head screws
C.
securing the deflector from inside the top front of the firebox, refer to
Figure 1.
D.
Place the gasket (provided) over the 4" (102mm) flue collar assembly and
bend along perforation.
From inside the firebox, insert the 4" (102mm) flue collar through the back
E.
of the firebox. Install the rear exit shield onto the 4" (102mm) flue collar,
see "REAR EXIT SHIELD" section for installation instructions.
Secure the flue collar assembly, gasket and rear exit shield using the four
F.
hex head 3/8" thread cutting screws, refer to Figure 2. NOTE: Do not
overtighten. The gasket needs only to be snug against the firebox.
G.
Reattach the deflector using the four screws and install the log set, glass
door and safety screen.
