GENERAL INFORMATION
LOCATION AND CLEARANCE
Make sure your installation location provides adequate combustion and ventilation air.
In selecting the location, the aesthetic and functional uses of the appliance are primary concerns.
However, vent system routing to the exterior and access to the fuel supply are also important.
Consideration should be given to traffic ways, furniture, draperies, etc., due to elevated surface
temperatures. The location should also be free of electrical, plumbing or other heating/air con-
ditioning ducts. Be sure to maintain adequate clearances around air openings into combustion
chamber.
The appliance should be mounted on a fully supported base extending the full width and depth
of the unit. The appliance may be located on or near conventional construction materials.
However, if installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or
wood barrier covering the entire bottom surface must be used.
Right and left sides of the unit are determined when standing in front of the unit.
Minimum clearance to combustibles: sides and back - 0", floor - 0" , adjacent wall to Front -
6".
Minimum clearance to combustibles for the vent system is 2" when passing through a wall or
chase.

INSTALLATION
VENT ASSEMBLY
There are two basic types of installations approved with your model DV23ZC appliance.
These are:
Horizontal termination (See Figure 5)
Vertical termination (See Figure 10)
When planning your installation, refer to Figure 3 to ensure the length of your vent falls into the
limits specified in Figure 3. Also consult page 9, “Exterior Vent Locations and Restrictions”
regarding the placement of the vent terminal.
HORIZONTAL TERMINATION
1. Set the gas appliance in its desired location. Check to determine if wall studs or roof rafters
are in the way when the venting system is attached. If this is the case, you may want to
adjust the location of the appliance.
2. Dura-Vent pipe and fittings are designed with special twist-lock connections. Assemble the
desired combination of pipe and elbows to the appliance adapter with pipe seams oriented
towards the wall or floor, as much out of view as possible.
3. Use only Dura-Vent #985 horizontal termination (wind cap).

NOTE:
Twist-lock procedure: Four indentations, located on the female ends of pipes and
‹
fittings, are designed to slide straight onto the male ends of adjacent pipes and fittings, by
orienting the four pipe indentations so they match and sliding into the four entry slots on the
male ends (Figure 4). Push the pipe sections completely together, then twist-lock one section
clockwise approximately one-quarter turn, until the two sections are fully locked.
‹
Horizontal runs of vent must be supported every three feet. Wall straps are available for
this purpose.

INSTALLATION
HORIZONTAL TERMINATION (continued)
NOTE:
‹
The horizontal run of vent must be level, or have a 1/4-inch rise for every 1 foot of run
toward the termination. Never allow the vent to run downward. This could cause high
temperatures and may present the possibility of a fire.
‹
A 2" clearance (airspace) MUST be maintained on all vent pipe.
4. With the pipe attached to the appliance adapter, slide the appliance into its correct location,
and mark the wall for a 10" x 10" square hole. The center of the square hole should line up
with the centerline of the horizontal pipe as shown in Figure 6. Cut and frame the 10"
square hole in the exterior wall where the vent will be terminated. If the wall being
penetrated is constructed of non-combustible material, e.g., masonry block or concrete, a 9"
diameter hole is acceptable.
5. Position the horizontal vent termination in the center of the 10" square hole, and attach to
the exterior wall with the four wood screws provided. Before attaching the Vent
Termination to the exterior wall, run a bead of non-hardening mastic around its outside
edges, so as to make a seal between it and the wall. (See Figure 7.) The arrow on the vent
cap should point up. (See Figure 6.) NOTE: Ensure that proper clearances to combustible
materials are maintained.

Note:
‹ The four wood screws provided should be replaced with appropriate fasteners for stucco,
brick, concrete, or other types of siding.
‹ Venting termination shall not be recessed into a wall or siding. For structures with vinyl
siding, a Vinyl Siding Standoff (Part 950) should be installed between the vent cap and the
exterior wall. (See Figure 7.) Attach the Vinyl Siding Standoff to the Horizontal Vent
Termination. The Vinyl Siding Standoff prevents excessive heat from possibly melting the
vinyl siding material.

7. Slide the appliance and vent assembly toward the wall, carefully inserting the vent pipe into
the vent cap assembly. It is important that the vent pipe extend into the vent cap a sufficient
distance so as to result in a minimum pipe overlap of 1 1/4". Secure the connection between
the vent pipe and the vent cap assembly into the outer wall of the vent pipe. Use two sheet
metal screws provided to connect the straps to the Pipe Section. (See Figure 8.)

INSTALLATION
VERTICAL TERMINATION
1. Set the gas appliance in the desired location. Drop a plumb bob down from the ceiling to
the position of the appliance flue exit, and mark the location where the vent will penetrate
the ceiling. Drill a small hole at this point. Next, drop a plumb bob from the roof to the hole
previously drilled in the ceiling, and mark the spot where the vent will penetrate the roof.
Determine if the ceiling joists, roof rafters or other framing will obstruct the venting system.
You may wish to relocate the appliance or to offset it as shown in Figure 9, to avoid cutting
load bearing members.
2. If an offset is necessary in the attic to avoid obstructions, it is important to support the vent
pipe every 3 feet, to avoid excessive stress on the elbows, and possible joint separation.
Wall straps are available for this purpose (Figure 9).

3. Assemble the desired lengths of pipe and elbows necessary to reach from the appliance
adapter up through the Round Support Box. Ensure that all pipe and elbow connections are
in their fully twist-locked position. (See Figure 10.)
4. Cut a hole in the roof centered on the small drilled hole made in the roof in Step 1. The hole
should be of sufficient size to meet the 2" requirements for clearance to combustibles.
Continue to assemble lengths of pipe and elbows necessary to reach from the Ceiling
Support Box up through the roof line. Galvanized pipe and elbows may be utilized in the
attic, as well as above the roof line. The galvanized finish is desirable above the roof line
due to its higher corrosion resistance.
NOTES:
‹ Maintain 2" minimum clearance.
‹ To install the Round Support Box/Wall Thimble in a flat ceiling, cut a 10" square hole in the
ceiling centered on the hole drilled in step 1 above. Frame the hole as shown in Figure 11.

VERTICAL TERMINATION (continued)
5. Slip the flashing over the Pipe Section(s) protruding through the roof. Secure the base of the
Flashing to the roof with roofing nails. Ensure the roofing materials overlap the top edge of
the Flashing as shown in Figure 12. Verify that you have at least the minimum clearance to
combustibles at the roof line.
Figure 12
6. Continue to add Pipe Sections until the height of the Vent Cap meets the minimum building
code requirements described in Figure 13. Note that for steep roof pitches, the vent height
must be increased. High wind conditions, nearby trees, adjoining roof lines, steep pitched
roofs, and other factors can result in poor draft, or down drafting. In these cases, increasing
the vent height may solve this problem.

VERTICAL TERMINATION (continued)
NOTES:
‹ Use only 45 degree elbows. Use of 90 degree elbows is not allowed in vertical terminations.
The 45 degree elbows offer less restriction to the flow of flue gases and intake air.
‹ For multi-story vertical installations, a Ceiling Firestop, (Simpson-Dura-Vent, Part 963) is
required at the second floor, and any subsequent floors (Figure 14). The opening should be
framed to 10" x 10" inside dimensions, in the same manner as shown in Figure 11.
Figure 14
‹ Any occupied areas above the first floor, including closets and storage spaces, which the
vertical vent passes through, must be enclosed. The enclosure may be framed and sheet rocked
with standard construction materials. However, consult the vent manufacturer’s installation
instructions for the minimum allowable clearance between the outside of the vent pipe and the
combustible surfaces of the enclosure. Do not fill any of the required air spaces with insulation.

OPERATION
PILOT AND FLAME
Your appliance is equipped with a standing pilot to ensure proper burner ignition. It is visible
by looking over the top of the middle log 6" from the right side. While igniting, the flame
should impinge on the lighting port tube between the rear and middle burner, which ignites the
front and rear burner.
Figure 19
When burning, the flame on the middle log should be primarily blue, about 1" to 2" tall and
causing a glowing effect on the face of the middle log. The rear flame should be 4" to 5" above
the top of the rear log.
GLASS DOOR INSTALLATION
Install the glass door on your appliance by placing the door brackets over the studs on the
stove: three at the top and three at the bottom. Simply tighten nut on each. Do not abuse door,
i.e. drop or slam it.
When the glass door has been removed for cleaning or service, carefully store it in a safe place.
If the door should become broken use caution when removing the broken glass from the frame.
