Vertical Through-the-Roof Applications
This Gas Fireplace has been approved for:
•
Vertical installations up to 40' (12 m) in height. Up
to a 10' (3 m) horizontal vent run can be installed
within the vent system using a maximum of two 90°
elbows. (Fig. 50)
Max. Height
40' (12m)
Min. Height

Fig. 50 Support straps for horizontal runs.
•
Up to two 45° elbows may be used within the
horizontal run. For each 45° elbow used on the
horizontal level the maximum horizontal length must
be reduced by 18" (457 mm).
Example: Maximum horizontal length
0 x 45° elbows = 10' 93 m)
1 x 45° elbows = 8¹⁄₂' (2.6 m)
2 x 45° elbows = 7' (2.1 m)
•
A minimum of an 8' (2.4 m) vertical rise.
•
Two sets of 45° elbows offsets within these vertical
installations. From 0 to a maximum of 8' (2.m) of
vent pipe can be used between elbows. (Fig. 51)
•
7DVCS must be used to support offsets. (Fig. 53)
This application will require that you first determine
the roof pitch and use the appropriate starter kit.
