FLUE VENTING INSTRUCTIONS
General Venting Information
The Mendota fireplace must be vented using the Mendota approved vent system components. Approved
brands of vent components include DuraVent, AmeriVent, ICC, Selkirk, Olympia, and Security vent pipes and
venting components. All warranties will be voided and serious fire, health, or other safety hazards may result
from any of the following actions: Installation by unauthorized personnel; installation of any damaged
component; unauthorized modification of vent system; installation of any components not approved by
Mendota; failure to meet all clearance requirements; failure to properly twist-lock and positively seal all
components. Consult local building codes before beginning the
installation.
Warning: Always maintain required clearances (air spaces) to
combustibles to prevent a fire hazard. Do not fill air spaces with
insulation. Check installation instructions for minimum clearance
requirements between the outer walls of the vent pipe and nearby
combustible surfaces. Be sure to check the vent termination clearance
requirements from decks, windows, soffit, gas regulators, air supply
inlets, and public walkways, as specified in these installation
instructions and local building codes.

Safety Precautions: 1) Wear gloves and safety glasses for protection; 2) exercise extreme caution when using
ladders or on rooftops; and 3) be aware of electrical wiring locations in walls and ceilings.
This gas fireplace and vent system must be vented directly to the outside of the building and never attached to a chimney
serving another solid fuel or gas burning fireplace. Each direct vent gas fireplace must have its own separate vent system.
Common vent systems are prohibited.
To assure proper venting performance of this high-performance Mendota fireplace, it is critical that all
brands of vent pipe sections are sealed tightly and leak-proof. This means that all pipe sections must be
carefully rotated into the fully "twist-locked" position.
We strongly recommend that fixed length pipe sections be used in place of telescoping sections whenever
possible. Note: Do not separate telescoping sections. They must be used as complete assemblies.
Note: When using vent pipe and components that do not incorporate a fiberglass or graphite gasket at the inner exhaust tube
joints, you must use Milpak 1000°F silicate stove sealant (#65-06-00909). Aluminum foil tape may be used on the outer (air
intake) pipe joint but is not mandatory. Local codes may vary. Contact the Mendota dealer for proper materials.
Component "Twist-Lock" Connection Procedure
DuraVent and American Metals pipe and fittings are designed with special twist-lock connections. Twist-lock
procedure is as follows:
Four indentations, located on the female ends of pipes and fittings are designed to slide straight into the
male ends of the adjacent pipes and fittings, by orienting the four pipe indentations so that they match and
slide into the four entry slots on the male ends.
Push the pipe sections completely together then twist-lock one section clockwise, approximately ¼ turn until
the two sections are fully locked. The female locking lugs will not be visible from the outside on the black
pipe or fittings. They may be located by examining inside of the female ends.
