Vertical Venting Requirements
These requirements apply to any installation that includes a verrtical vent run.
The GF 200 DV Lillehammer can be vertically vented through a roof or ceiling following these guidelines:
Steep roofs, nearby trees, and predominantly windy conditions can contribute to poor draft or
Use Simpson
Whenever possible use 45° elbows instead of 90° elbows as they are less restrictive to exhaust gas and intake air flow.
GAS VENT RULE: In no case shall any discharge opening on the cap be less than 2' (610mm) horizon- tally from the roof surface. See Figure 11.
A firestop is required at every floor. The opening should be framed to 10" X 10" inside dimension.
Simpson Dura-Vent Ceiling Firestop #943 is required.
Any venting that is exposed above the first floor, regardless of attic space or living space, must be enclosed. Always maintain the required 1" clearance from all sides of the vertical vent system.
Install the Exhaust Gas Restrictor in all Vertically Terminated vent systems. See the Adding Restriction section on page 8.
