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.

1. This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases unless a certiﬁ ed kit is used.

2. For propane/LP ﬁ replace, do not place propane/LP supply tank(s) inside any structure. Locate propane/ LP supply tank(s) outdoors. To prevent performance problems, do not use propane/LP fuel tank of less than 100 lbs. capacity.

3. If you smell gas

• shut off gas supply.

• do not try to light any appliance.

• do not touch any electrical switch; do not use any

phone in your building .

• immediately call your gas supplier from a neigh-

bor’s phone. Follow the gas supplier’s instructions.

4. Never install the ﬁ replace

• in a recreational vehicle

•

where curtains, furniture, clothing, or other ﬂ am-

mable objects are less than 42" from the front, top, or sides of the ﬁ replace

• in high trafﬁ c areas

• in windy or drafty areas

5. This ﬁ replace reaches high temperatures. Keep chil- dren and adults away from hot surfaces to avoid burns or clothing ignition. Fireplace will remain hot for a time after shutdown. Allow surfaces to cool before touching.

6. Young children should be carefully supervised when they are in the same room as the appliance. Toddlers, young children and others may be susceptible to accidental contact burns. A physical barrier is recommended if there are at risk individuals in the house. To restrict access to a ﬁ replace or stove, install an adjustable safety gate to keep toddlers, young children and other at risk individuals out of the room and away from hot surfaces.

7. Do not modify ﬁ replace under any circumstances. Any parts removed for servicing must be replaced prior to operating ﬁ replace.

8. Turn ﬁ replace off and let cool before servicing, install- ing, or repairing. Only a qualiﬁ ed service person should install, service, or repair the ﬁ replace. Have burner system inspected annually by a qualified service person.

9. You must keep control compartments, burners, and circulating air passages clean. More frequent cleaning may be needed due to excessive lint and dust. Turn off the gas valve and pilot light before cleaning ﬁ replace.

10. Have venting system inspected annually by a qualiﬁ ed service person. If needed, have venting system

cleaned or repaired. Refer to Cleaning and Mainte- nance, Page 49.

11. Keep the area around your ﬁ replace clear of combus- tible materials, gasoline, and other ﬂ ammable vapor and liquids. Do not run ﬁ replace where these are used or stored. Do not place items such as clothing or decorations on or around ﬁ replace.

12. Do not use this ﬁ replace to cook food or burn paper or other objects.

It is normal for ﬁ replaces fabricated of steel to give off some expansion and/or contraction noises during the start up or cool down cycle. Similar noises are found with your furnace heat exchanger or car engine.

IMPORTANT:

PLEASE READ THE FOLLOWING

CAREFULLY

It is not unusual for gas ﬁ replaces to give off some odor the first time it is burned. This is due to the manufacturing process.

Please ensure that your room is well ventilated

during burn off — open all windows.

It is recommended that you burn your ﬁ replace for at least ten (10) hours the ﬁ rst time you use it. Place the fan switch in the “OFF” position during this time.

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).

Place ﬁ replace into position. Measure the vertical height (X) required from the base of the ﬂ ue collars to the center

of the wall opening. Figure 12

Step 4

Using appropriate length of pipe section(s) attach to ﬁ re- place with three (3) screws. Follow with the installation of the elbow.

Step 5

Measure the horizontal length requirement ﬁ guring a 11⁄4” (32 mm) overlap, i.e. from the elbow to the outside wall

cap. Figure 13

Figure 13 Horizontal Length Requirement

FP1182

Always install horizontal venting on a level

plane.

Step 6

Use appropriate length of pipe sections - telescopic or ﬁ xed - and install.

Sealing vent pipe and ﬁ restop gaps with high tem- perature sealant will restrict cold air being drawn in around ﬁ replace.

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.

Support horizontal pipes every 36” (914

mm) with metal pipe straps.

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. See the Sidewall Venting Graph for extended horizontal run if the vertical exceeds 24".

INSTALLATION FOR VERTICAL TERMINATION

1. Determine the route your vertical venting will take. If 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

2. Assemble the desired lengths of pipe and elbows necessary to reach from the burner system ﬂ ue up through the ﬁ restop. Be sure pipe and elbow connections are fully twist-locked.

3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before

cutting hole in roof). The 101/2"x10

" (267 x 267 mm) hole must be measured on the horizontal. Actual length may be larger depending on the pitch of the roof. There 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.

KHLDV Series Gas Fireplace

100 gallon (min) Propane/LP Supply Tank

A qualiﬁ ed installer or service person must connect appliance to gas supply. Follow all local codes.

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.

Vent Pointing Down

FP1977

Figure 27 External Regulator with Vent Pointing Down (Propane/LP Only)

Use only new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section

2.6.3, providing gas meets hydrogen sulﬁ de limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure (listed on data plate)

CAUTION

at the maximum ﬂ ow rate (BTU/hr). Undue pressure loss will occur if the pipe is too small.

When using copper of ﬂ ex connectors use only ﬁ ttings approved for gas connections. The gas control inlet is 3/8" NPT.

For propane/LP units, never connect ﬁ replace directly to the propane/LP supply. This burner system requires an external regulator (not supplied). Install the external regulator between the burner system and
