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)

H
= H
+ H
+ H
= 1FT (0.3m) + 1FT (0.3m) + 10.75FT (3.3m) = 12.75FT (3.9m)

H
= .03 (four 90° elbows + one 45° elbow - 90°)
O
= .03 (360° + 45° - 90°) = 6.75 FT (2.1m)
H
= H
+ H

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.
GX36 ONLY: Natural gas models come equipped with a #43 orifi ce and propane models come equipped
with #54 orifi ces. These orifi ce sizes are suitable for rear vent installations that exit directly out the wall
(no vertical rise). The main burner orifi ce should be changed to the #42 orifi ce for natural gas and a
#53 orifi ce for propane, when venting off the top of the appliance.
A.
Remove the safety screen and glass front, refer
to " SAFETY SCREEN / DOOR REMOVAL AND
INSTALLATION" section.
B.
Remove the contents from the fi rebox and set aside, you
will need the exhaust fl ue collar from the top of the log
carton.
C.
To ease assembly, remove the four hex head screws
securing the defl ector from inside the top front of the
fi rebox, refer to Figure 1.
D.
Place the gasket (provided) over the 4" (102mm) fl ue collar assembly and
bend along perforation.
E.
From inside the fi rebox, insert the 4" (102mm) fl ue collar through the back
of the fi rebox. Install the rear exit shield onto the 4" (102mm) fl ue collar,
see "REAR EXIT SHIELD" section for installation instructions.
F.
Secure the fl ue collar assembly, gasket and rear exit shield using the four
hex head 3/8" thread cutting screws, refer to Figure 2. NOTE: Do not
overtighten. The gasket needs only to be snug against the fi rebox.
G.
Reattach the defl ector using the four screws and install the log set, glass
door and safety screen.
