VENTING
Locate and mark the center point of the vent pipe using a nail on the underside of the roof. Drive the nail
through the center point. Mark the outline of the roof hole around this center point.
NOTICE:
Size of the roof hole dimensions depend on the pitch of the roof. There must be a 1 inch
(25 mm) clearance to the vertical pipe sections. This clearance is to all combustible material.
Cover the opening of the vent pipe and cut and frame the roof hole. Use framing lumber the same size
as the roof rafters and install the frame securely. Flashing anchored to frame must withstand high winds.
The storm collar is placed over this joint to make a water-tight seal. Non-hardening sealant should be
used to completely seal this flashing installation.
4.6 Minimum Vent Height Above the Roof
WARNING
Building codes specify minimum chimney and vent height above the roof top.
These minimum heights are necessary in the interest of safety.

Note that for steep roof pitches, the vent
height must be increased. In high wind
conditions, nearby trees, adjoining roof
lines, steep pitched roofs, and other similar
factors can result in poor draft, or down-
drafting. In these cases, increasing the vent
height may solve this problem.
4.7 Installing the Vent System in a Chase
A chase is a vertical box-like structure built to enclose the gas fireplace and its vent system. Vertical vent
runs on the outside of a building may be, but are not required to be installed inside a chase.
CAUTION
Treatment of firestop spacers and construction of the chase may vary with the type of
building. These instructions are not substitutes for the requirements of local building
codes. Check local building codes to determine the requirements for these steps.
NOTICE:
Build the chase large enough to maintain the minimum clearance of combustible materials
(including insulation) to the vent system. When installing the vent system in a chase, insulate the chase as
you would the outside walls of your home. This is especially important in cold climates. Upon completion
of chase framing, install the vent system by following the instructions in this manual.
