Flue Venting Instructions - Mendota DXV-42 Installation & Operating Instructions Manual

FLUE VENTING INSTRUCTIONS

The Mendota Fireplace must be vented using the Mendota certified DuraVent or American Metals venting
system. 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 manufactured or approved by
Simpson DuraVent, American Metals and Mendota; failure to meet all clearance requirements; failure to
properly twist-lock 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 clear-
ance requirements from decks, windows, soffits, gas regulators, air supply inlets, and public walkways, as
specified in these installation instructions and local building codes.
SAFETY PRECAUTIONS FOR THE
1) Wear gloves and safety glasses for protection; 2) Exercise extreme caution when using
INSTALLER:
ladders or on roof tops; and 3) Be aware of electrical wiring locations in walls and ceilings.
The gas appliance and vent system must be vented directly to the outside of the building, and never at-
tached to a chimney serving separate solid fuel or gas burner appliance. Each direct vent gas appliance
must have its own separate vent system. Common vent systems are prohibited.
To assure proper venting performance of the high-performance Mendota Direct Vent Fireplaces and
Stoves, it is critical that the DuraVent GS and American Metals vent pipe sections are sealed tightly and
leak-proof. This means that all pipe sections must be carefully rotated into the fully "twist-locked" posi-
tion. When using Dura Vent GS pipes, all inner pipe joints must be sealed using heat safe 2000F Silicate
Stove Masonry Sealant.
WE STRONGLY RECOMMEND THAT FIXED LENGTH PIPE SECTIONS BE USED IN PLACE
OF TELESCOPING SECTIONS WHENEVER POSSIBLE
Note: When using Dura-vent DV pipe you must use a silicate stove masonry sealant [Millpak Sealant
#65-06-00909] on all inner pipe joints. On the exterior (air intake) pipe joints, high temperature foil
tape may be used instead of the masonry sealant. Contact your dealer to obtain this sealant material.
DO NOT SEPARATE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE
ASSEMBLIES.
COMPONENT "TWIST-LOCK" CONNECTION PROCEDURE
DuraVent and American Metals pipes and fittings are designed with special
twist-lock connections. Twist-lock procedure is as follows: four (4) indenta-
tions, located on the female ends of pipes and fittings are designed to slide
straight in to the male ends of the adjacent pipes and fittings, by orienting the
four pipe identifications so that they match and slide into the four entry slots on
the male ends (FIGURE 4).
Push the pipe sections completely together then twist-lock one section clock-
wise, approximately 1/4 turn until the two sections are fully locked. The fe-
male 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
