When terminating the vent cap near an exterior wall or overhang,
maintain minimum clearances as shown in Figure 44.

General Maintenance
Conduct an inspection of the venting system semi-annually.
Recommended areas to inspect are as follows:
1. Check areas of the venting system which are exposed to the
elements for corrosion. These will appear as rust spots or
streaks and, in extreme cases, holes. These components should
immediately be replaced.
2. Remove the cap and shine a flashlight down the vent. Remove
any bird nests or other foreign material.
3. Check for evidence of excessive condensate, such as water
droplets forming in the inner liner and subsequently dripping
out at joints. Condensate can cause corrosion of caps, pipe and
fittings. It may be caused by having excessive lateral runs, too
many elbows and exterior portions of the system being exposed
to cold weather.
4. Inspect joints to verify that no pipe sections or fittings have been
disturbed and, consequently, loosened. Also, check mechanical
supports, such as wall straps or plumbers' tape for rigidity.
Venting terminal shall not be recessed into a wall or siding.
A removable panel or other means must be provided in the enclosure
for visual inspection of the flue connection.
NOTE: This also pertains to vertical vent systems installed on the
outside of the building.
Slide the vertical vent cap over the ends of the vent pipe and secure.
See Figure 44.

Installing the Vent System in a Chase
A chase is a vertical box-like structure built to enclose the gas
appliance and/or it's 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.
Therefore, your local building codes must be checked to determine
the requirements for these steps.
NOTE: When installing this vent system in a chase, it is always good
building practice to insulate the chase as you would the outside
walls of your home. This is especially important for cold climate
installations. Upon completion of building your chase framing,
install the vent system by following the instructions in this manual.
Remember to build the chase large enough so that minimum
clearance of combustible materials (including insulation) to the vent
system are maintained.
Reassembly and Resealing Vent Pipe System
Attach vent pipe to inlet and outlet vent adaptor on fireplace, replace
horizontal and vertical pipe lengths, elbows and horizontal or vertical
termination kit.
All vent system components lock into place by sliding the
concentric pipe section with four equally spaced interior beads onto
the appliance collar or previously installed component end with
four equally spaced indented sections. When the internal beads of
each starting outer pipe line up, rotate pipe section clockwise 90°
(approximately 3 inches). The vent pipe is now locked together.
