Standard Vertical-roof kit (Exhaust & intake outside)
Figure 9.8 (vertical pipe Φ 3.1 / Φ 4.9 in)
This kit allows vertical termination of the flue pipe through the roof. The kit is 1.2 min
length. Extension pieces (Co--axial) are also available which allows the flue system to be
extended to a total overall maximum permissible length.
Optional 45° and 90° elbows can be used to offset the flue route.
Each additional elbow reduces the overall acceptable length of the flue system as follows:
45° reduce length by 1.6 ft.
90° reduce length by 3.2 ft.
Installation:
• Drill hole through the outside roof.
•
