Vent System Approvals

VENTING AND INSTALLATION

Figure 8 shows the vent termination caps and systems approved for use with these models. Approved vent system terminations are labeled for identiﬁcation. 3-inch diameter listed ﬂexible aluminum or stainless steel gas vent is used for both the incoming combustion air and exhaust vent pipes. NO OTHER VENTING SYSTEMS OR COMPONENTS MAY BE USED. Detailed installation instructions are included with each vent termination kit and should be used in conjunction with this manual.

Horizontal Venting

The vent system on this model CANNOT be terminated horizontally.

Vertical Venting

The inlet and exhaust vent pipes MUST be connected to the proper collars on the unit AND to the termination cap or the unit will not operate. The intake vent collar is identiﬁed by a stamped “I” on the top collar sliding vent plate assembly.

WARNING: MAJOR U.S. BUILDING CODES SPECIFY MINIMUM CHIMNEY AND/OR VENT HEIGHT ABOVETHE ROOFTOP.THESEMINIMUMHEIGHTS ARE NECESSARY IN THE INTEREST OF SAFETY. SEE FIGURES 8 THROUGH 10 FOR MINIMUM HEIGHTS, PROVIDED THE TERMINATION CAP IS AT LEAST 2-FEET FROM A VERTICAL WALL AND 2-FEET BELOW A HORIZONTAL OVERHANG.

Note: This also pertains to vertical vent systems installed on the outside of the building.

WARNING: THE EXHAUST PIPE MUST ONLY BE CONNECTED TO THE EXHAUST STARTING COLLAR OF THE UNIT AND TO THE EXHAUST COLLAR OF THE TERMINATION CAP.

THE INLET AIR PIPE MUST ONLY BE CONNECTED TO THE INLET AIR STARTING COLLAR OF THE UNIT AND TO THE INLET AIR COLLAR OF THE TERMINATION CAP. BOTH THE INLET VENT AND THE FLUE VENT MUST BE CONNECTED FROM THE INSERT TO THE VENT TERMINATION CAP.

NOTE: The minimum vertical vent rise is 12 feet and the maximum vertical vent rise is 35 feet. These dimensions are measured from the starting collars of the unit to the end of the last section of vent pipe. See Figure 8.

NOTE: The damper of the masonry chimney may need to be removed to allow installation of the ﬂexible-vent pipe.

When installing into a zero clearance, factory built wood-burning ﬁreplaces, the use of the DVKI Round Vertical Termination Kit should allow you to mount the vent adaptor and cap to the exposed round chimney pipe easily.

Connecting the Vent Pipe

Caution: Sharp edges. Always use gloves when installing.

Install the 3-inch ﬂexible vent pipes down through the chimney.

Attach the pipe-to-cap adaptor to the termination cap and the top of the ﬂexible vent pipe, then install the cap to the top of the chimney.

Remove the vent slide plate assembly from the top of the insert. See Figure 7. Trim off excess venting then attach and secure the bottom ends of the ﬂex pipes to the starting collars with the adjustable band clamps provided. Slide the gas insert into place, and position any excess ﬂex vent pipe back up into the chimney. Begin installation of the insert into the ﬁreplace opening. Align the vent slide plate assembly with the guides located on top of the insert. Work the insert inch by inch into the ﬁreplace cavity as you pull forward on the vent slide plate assembly. Do not use excessive force on the vent slide plate. Once the vent slide plate is close to seating, install the vent bolt through the center hole of the insert top ﬂange, and into the vent slide plate nut. Using a wrench or socket, tighten the bolt until the vent slide plate is seated forward completely.

Positioning, Leveling, and Securing Insert

1.Place the insert into position.

Note: The front ﬂanges of the insert (without surround panels) should be set at approximately 1”(inch) in front of the face of the ﬁreplace.

2.Level the insert from side to side and front to back.

3.If necessary, use the leveling bolts included in the instruction pack. Screw the legs into the nuts installed in the bottom of the insert. Turn legs in until insert is level.

CAUTION: TO AVOID DOWNDRAFTS AND/OR COLD AIR PROBLEMS, IT IS RECOMMENDED TO SEAL OFF THE AREA BETWEEN THE TERMINATION CAP AND THE TOP OF THE SOLID-FUEL CHIMNEY OPENING INTO WHICH THE VENT CAP HAS BEEN INSTALLED.
