Top Vent And Rear Vent Options Discussion - Mendota DXV-35 DEEP TIMBER II Installation & Operating Instructions Manual

TOP VENT AND REAR VENT OPTIONS DISCUSSION

This Mendota Fireplace can be vented using AMERIVENT, DURAVENT, SELKIRK METALBESTOS, SECURITY CHIMNEY
brands of coaxial pipe off the top or using 5"x8" coaxial pipe off the rear. Use only Mendota specified vents and vent caps when in-
stalling your fireplace. Closely follow venting locations, directions and requirements provided in this Manual. Observe the restric-
tions related to vent position on exterior of home (see PG. 8).
Make certain that all vent pipe sections are fully twist-locked and leak-proof. Note: When using Dura-vent pipe you must use a sili-
cate stove masonry sealant [Milpak Sealant #65-06-00909] on all inner pipe joints. On the exterior (air intake) pipe joints, high tem-
perature foil tape may be used instead of the masonry sealant. Contact your dealer to obtain this sealant material.
TOP VENTING
The DXV-35 Fireplace comes from the factory configured for venting off the top using 4" x 6-5/8" Coaxial Vent Pipes.
AMERIVENT, DURAVENT, SELKIRK METALBESTOS, SECURITY CHIMNEY brand pipes and venting components may be
used when venting off the top.
Venting off the top on the DXV-35 Fireplace provides a large degree of flexibility for many venting configurations. However, a few
critical limitations must be understood and adhered to prior to planning to vent off the top.
Limitation: A 12" vertical pipe section must be connected to the top starter collar of the DXV-35. With the 12" vertical section
connected, you may only install one 90-degree elbow and a maximum 6" horizontal pipe section before connecting the horizontal
vent cap.
Limitation: The maximum horizontal run allowed when venting off the top is 12 feet in conjunction with a minimum 4 feet ver-
tical run. This 12 feet horizontal run can only be used if a straight vertical run of 48 inches (4 feet) is connected directly to the
top of the DXV35. DO NOT EXCEED THE MAXIMUM 12 FEET HORIZONTAL RUN. EVEN IF THE VERTICAL
SECTION YOU INSTALLED IS GREATER THAN 4 FEET, DO NOT EXCEED THE 12 FEET MAXIMUM HORIZONTAL
RUN THROUGHOUT THE ENTIRE VENT SYSTEM.
REAR VENTING
This DXV35 Fireplace can be optionally vented directly off the rear using AMERIVENT, DURAVENT, SELKIRK
METALBESTOS, SECURITY CHIMNEY brand Coaxial vent pipes and venting components.
The rear Vent Option is only allowed when installing this Fireplace against an outside Flat wall or in an outside corner. Only horizon-
tal runs are allowed. No vertical sections or components may be installed.
ORIFICE SIZES REQUIREMENT: When the DXV35 employs the rear vent option, the rear burner orifice must be changed in the
Natural Gas configuration to a #53 Spud Orifice (supplied with the Fireplace) and in an LPG configuration to a #61 Spud Orifice
(supplied with the Fireplace). The front burner orifice remains unchanged at #42 for Natural Gas applications and #55 for LPG appli-
cations.
For all framing, venting and installation requirements when venting directly off the rear, thoroughly read the Information and Instruc-
tions contained in this manual. ONLY THE VENTING CONFIGURATIONS SHOWN ON PAGE 22 OF THIS MANUAL ARE
ALLOWED WHEN VENTING OFF THE REAR.
LOCATING THE DXV35 WHEN USING THE REAR VENT OPTION: SEE PAGE 22 OF THIS MANUAL. The Rear Vent
Option may only be used when installing the DXV35 with Rear-Vent-Option against an exterior flat wall or an exterior corner of the
home.
