OWNER
Please retain these instructions for future reference
WARNING
• Read this owner’s manual carefully and completely before trying to assemble, operate, or service this
fi replace.
• Any change to this fi replace or its controls can be dangerous.
• Improper installation or use of this fi replace can cause serious injury or death from fi re, burns, explosions,
electrical shock and carbon monoxide poisoning.
This fi replace is a vented product. This fi replace must be
properly installed by a qualifi ed service person. The glass
door must be properly seated and sealed. If this unit is not
properly installed by a qualifi ed service person with glass
door properly seated and sealed, combustion leakage
can occur.
CARBON MONOXIDE POISONING: Early signs of carbon
monoxide poisoning are similar to the fl u with headaches,
dizziness and/or nausea. If you have these signs, the fi re-
place may not have been installed properly. Get fresh air
at once! Have the fi replace inspected and serviced by a
qualifi ed service person. Some people are more affected
by carbon monoxide than others. These include pregnant
women, people with heart or lung disease or anemia, those
under the infl uence of alcohol, and those at high altitudes.
Propane/LP gas and natural gas are both odorless. An
odor-making agent is added to each of these gases. The
odor helps you detect a gas leak. However, the odor added
to these gases can fade. Gas may be present even though
no odor exists.
Make certain you read and understand all warnings. Keep
this manual for reference. It is your guide to safe and proper
operation of this fi replace.

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
It is important to select the proper length of vent pipe for
the type of termination you choose. It is also important to
note the wall thickness.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise desired. All horizontal run
of venting must have 1/4" rise for every 12" of run towards
the termination below 71⁄2" of vertical rise from fl oor of fi re-
place. With 71⁄2 feet or more of vertical rise from the fl oor
of the fi replace, the horizontal run may be level. NEVER
run vent piping down.
You may use up to three 90° elbows in this vent confi gura-
tion. Refer to Vertical/Horizontal Termination Confi gurations
on Page 16.
Horizontal venting which incorporates the twist lock pipe
must be installed on a level plane without an inclining or
declining slope.
FOR VERTICAL TERMINATION
Measure the distance from the fi replace fl oor to the ceil-
ing. Add the ceiling thickness, the vertical rise in an attic
or second story, and allow for suffi cient vent height above
the roof line.
NOTE: You may use two 45° elbows in place of a 90° elbow.
You must follow rise to run ratios when using 45° elbows.
The appliance is approved for use with three 90° elbows
maximum or a combination of 90° and 45° elbows up to
a maximum of 270°.
Treatment of fi restops and construction of
the chase may vary from building type to
building type. These instructions are not
substitutes for the requirements of local
NOTICE
building codes. You must follow all local
building codes.
When installing in a chase, you should
insulate the chase as you would the outside
walls of your home. This is especially
important in cold climates. Insulation
should be considered a combustible
NOTICE
material. Maintain proper clearances to all
combustible materials.
VENTING INSTALLATION
Never run the vent pipe down. This may
cause excessive temperatures which could
cause a fi re.
WARNING
For two-story applications, fi restops are required at each
fl oor level. If an offset is needed in the attic, additional pipe
and elbows will be required.
You may use a chase with a vent termination with exposed
pipe on the exterior of the house. See Installing A Vent
System in an Outside Chase below. If pipe is enclosed in
chase, it is not exposed.
It is very important that the venting system maintain its
balance between the combustion air intake and the fl ue
gas exhaust. Certain limitations apply to vent confi gurations
and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN
OUTSIDE CHASE
A chase is a vertical boxlike structure built to enclose
venting that runs along the outside of a building. A chase
is required for such venting.
Always maintain minimum clearances
around vent systems. The minimum
clearances to combustibles for horizontal
vent pipe are 3" at the top* and 1" at the
sides and bottom of the vent system until
the pipe penetrates the nearest vertical
wall (1" required). A 1" minimum clearance
all around the pipe must be maintained at
outside wall and on vertical runs. Do not
WARNING
pack the open air spaces with insulation
or other materials. This could cause high
temperatures and may present a fi re hazard.
*Unless the vertical run is 7
from fl oor of fi replace, the clearance for the
horizontal run is 1" on all sides.

HOW TO USE THE VENT GRAPH
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimensions
of the vent system.
1. Determine the height of the center of the horizontal vent
pipe exiting through the outer wall. Using this dimension
on the Sidewall Vent Graph below, locate the point
intersecting with the slanted graph line.
2. From the point of this intersection, draw a vertical line
to the bottom of the graph.
3. Select the indicated dimension, and position the fi re-
place in accordance with same.
Example: If the vertical dimension from the fl oor of the
fi replace is 11' (3.4 m) the horizontal run to the face of
the outer wall must not exceed 16' (4.9 m).

Step 7
Guide the vent terminations 5” and 8” collard into their
respective vent pipes. Double check that the vent pipes
overlap the collars by a minimum of 11⁄4" (32 mm). Secure
the termination to the wall with screws provided and caulk
around the wall plate to weatherproof. As an alternative to
screwing the termination directly to the wall, you may also
use expanding plugs or an approved exterior construction
adhesive.

VERTICAL/HORIZONTAL TERMINATION
CONFIGURATIONS
Since it is very important that the venting system
maintain its balance between the combustion air intake
and the fl ue gas exhaust, certain limitations as to vent
confi gurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between vertical
and horizontal side wall venting, will help to determine the
various dimensions allowable. Figure 10
NOTE: Horizontal sections of this vent system require
a minimum of 3" clearances to combustibles at the top
of the fl ue and 1" clearance at the sides and bottom
until the fl ue penetrates the outside wall. A minimum
1" clearance all around the fl ue is acceptable at this
point of penetration. Unless the vertical run is 71⁄2 feet
or higher from fl oor of fi replace, the clearance for the
horizontal run is 1" on all sides.
Vertical sections of this vent system require a minimum
of 1" clearance to combustibles on all sides of the pipe.
When vent exits through foundations less than 20" below
outcrop, the termination must be fl ush up with outcropped
wall above.
It is best to locate the fi replace in such a way that minimizes
the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the fl ue collar of the fi replace (or the top of the
Transition Elbow) to the face of the fi nished outside wall.

BELOW GRADE INSTALLATIONS
When it is not possible to meet the required vent terminal
clearances of 12" above grade level, a snorkel kit is recommended. It allows installation depth down to 7" (178
mm) below grade level. The 7" (178 mm) is measured
from the center of the horizontal vent pipe as it penetrates
through the wall.
Ensure that sidewall venting clearances are observed.
If venting system is installed below ground, we recommend a window well with adequate and proper drainage
to be installed around the termination area.
If installing a snorkel, a minimum 24" vertical rise is necessary. The maximum horizontal run with the 24” vertical pipe
is 36". This measurement is taken from the collar of the
fi replace (or transition elbow) to the face of the exterior wall.

ceiling joist, roof rafters or other framing will obstruct
the venting system, consider an offset. Refer to Figure
23 to avoid cutting load bearing members.
Roof Flashing
KHLDV Series Gas Fireplace
For optimal fl ame appearance, a restrictor disk is necessary
on straight vertical runs of 10' of more.
• Runs may not incorporate elbows.
• The disk is part number 56D3027 and is included in
installation manual packet.
• Drop the disk into a 5" inner collar before installing
the fi rst section of fl ue or install at the last section
before installing the termination.
• An additional disk may be installed on runs of 35' or more.
Rotate disks perpendicular to each other.
NOTE: Pay special attention to these installation instructions
for required clearances (air space) to combustibles when
passing through ceilings, walls, roofs, enclosures, attic
rafters, etc. Do not pack air spaces with insulation. Also
note maximum vertical rise of the venting system and any
maximum horizontal offset limitations. Offsets must fall
within the parameters shown in Figures 22 and 23.
2. Set fi replace in desired location. Drop a line plumb down
from the ceiling to the position of the fl ue exit. Mark the
center point where the vent will penetrate the ceiling.
Drill a small locating hole a this point.
Drop a plumb line from the inside of the roof to the ceiling
locating hole in the ceiling. Mark the center point where
the vent will penetrate the roof. Drill a small locating hole
at this point.
FLAT CEILING INSTALLATION
1. Cut a 101/2" (241 mm) square hole in the ceiling using
the locating hole as a center point The opening should
be framed to 101/2"x101/2" (241 x 241 mm) inside dimen-
sions as shown in Figure 25 using framing lumber the
same size as the ceiling joist. If the area above the
ceiling is an insulated ceiling or a room, nail fi restop from
the top side. This prevents loose insulation from falling
into the required clearance space. Figure 24. Otherwise,
install fi restop below the framed hole. Figure 25

must be a 1" minimum clearance from the vent pipe to
combustible materials. (Insulation should be considered
a combustible material).
4. Connect a section of pipe and extend up through the
hole.
NOTE: If an offset is needed to avoid obstructions, you
must support the vent pipe every three (3) feet. Use wall
straps for this purpose. Refer to Page 18, Figure 21.
Whenever possible, use 45° elbows instead of 90° elbows.
The 45° elbow offers less restriction to the fl ow of the fl ue
gases and intake air.
5. Place the fl ashing over the pipe section(s) extending
through the roof. Secure the base of the fl ashing to
the roof and framing with roofi ng nails. Be sure roofi ng
material overlaps the top edge of the fl ashing. There
must be a 1" clearance from the vent pipe to combustible
materials.
6. Continue to add pipe sections until the height of the vent
cap meets the minimum building code requirements.
NOTE: You must increase vent height for steep roof
pitches. Nearby trees, adjoining roof lines, steep pitched
roofs, and other similar factors may cause poor draft or
down-drafting in high winds. Increasing the vent height
may solve this problem.
NOTE: If the vent pipe passes through any occupied areas
above the fi rst fl oor, including storage spaces and closets,
you must enclose pipe. You may frame and sheetrock the
enclosure with standard construction material. Make sure
to meet the minimum allowable clearances to combustibles.
Do not fi ll any of the required clearance spaces with
insulation.

WARNING
INSTALLATION ITEMS NEEDED
Before installing fi replace and burner system, make sure
you have the items listed below.
• Test gauge connection* • Tee joint
• Equipment shutoff valve* • Pipe wrench
• Sediment trap (recommended)
• External regulator (supplied by installer)
• Piping (check local codes)
• Sealant (resistant to propane/LP gas)
• Approved fl exible gas line with gas connector (if
allowed by local codes — not provided)
* A CSA design-certifi ed equipment shutoff valve with 1/8"
NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certifi ed equipment shutoff
valve from your dealer.
For propane/LP connections only, the installer must supply
an external regulator. The external regulator will reduce
incoming gas pressure. You must reduce incoming gas
pressure to between 11 and 13 inches of water. If you do
not reduce incoming gas pressure, burner system regulator
damage could occur. Install external regulator with the vent
pointing down as shown in Figure 27. Pointing the vent
down protects it from freezing rain or sleet.

the appliance. Union tee and plugged 1/8" NPT pressure
tapping point should be installed upstream of the appliance.
Figure 28
IMPORTANT: Install main gas valve (equipment shutoff
valve) in an accessible location. The main gas valve is for
turning on or shutting off the gas to the fi replace.
Check your building codes for any special requirements for
locating equipment shutoff valve to fi replaces.
Apply pipe joint sealant lightly to male threads. This will
prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged burner system valves.
A manual shutoff valve must be installed
upstream of the appliance. Union tee
