Flue Venting Instructions - Mendota DXV-60 Installation & Operating Instructions Manual

The Mendota Fireplace must be vented using DuraVent or Amerivent 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 security chimney Simpson DuraVent, Ameri-
vent and Mendota; failure to meet all clearance requirements; failure to properly twist-lock all components.
Consult local building codes before beginning the installation.
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, soffitts, gas regulators, air supply inlets, and public walkways, as specified in these in-
stallation instructions and local building codes.
and safety glasses for protection; 2) Exercise extreme caution when using 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 attached 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 vent pipe sections are sealed tightly and leak-proof. This means that all pipe sec-
tions must be carefully rotated into the fully "twist-locked" position (Dura Vent only).
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 heat safe silicate stove masonry sealant. As an al-
ternative, high temperature tape may be used on the outer (air intake) pipe joint instead of the stove sea-
lant.
DO NOT SEPARATE TELESCOPING SECTIONS. THEY MUST BE USED AS COMPLETE
ASSEMBLIES. (Dura Vent only)
COMPONENT "TWIST-LOCK" CONNECTION PROCEDURE (Dura Vent
only)
DuraVent pipe and fittings are designed with special twist-lock connections. Twist-
lock procedure is as follows: four (4) indentations, 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 clockwise,
approximately 1/4 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
HIGH ALTITUDE INSTALLATION INFORMATION: Prior to installing at altitudes higher than 7500, please con-
tact the Mendota technical service department for specific venting requirements and venting restrictions.
