SAFETY INFORMATION

WARNINGS
IMPORTANT: Read this owners manual carefully and completely before trying to assemble, operate, or service this fireplace. Improper use of this fireplace can cause serious injury or death from burns, fire, explosions, electrical shock, and carbon monoxide poisoning.
DANGER: Carbon monoxide poisoning may lead
to death!
This fireplace must be installed by a qualified (certified or licensed) service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe within a pipe and having the same center) venting system. It brings in fresh air for combustion through the outer pipe and combustion gases are exhausted through the inner pipe. If the glass door assembly and venting pipe are not properly seated, connected, and sealed, carbon monoxide leakage (spillage) can occur.
Carbon Monoxide Poisoning: Early signs of carbon monoxide
poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the fireplace may not have been installed properly. Get fresh air at once! Have fireplace inspected and serviced by a qualified 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 influence 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.

Location and Space Requirements

PRODUCT FEATURES

These are a few facts that can help you understand and enjoy your direct-vent fireplace:
• The venting system may be routed to the outside of your home
in several ways. It may vent through the roof (vertical) or it may vent to an outside/exterior wall (horizontal). The vent pipe in­stallation is very important to allow for proper operation. You must follow the venting instructions very carefully for either vertical or horizontal applications.
• This fireplace may be installed in any room of your house provided
all local codes and these installation instructions are followed.
• This fireplace does not require electricity to operate.
• Only the blower requires electricity if installed and if you plan
to install the blower at a later date, do not forget to wire the outlet at the bottom of the fireplace when framing.
• A piezo ignitor and ceramic electrode create spark to ignite the
pilot light. It does not require any matches, batteries or any other sources of ignition to light the pilot.
• Each time you turn on your fireplace, you may notice some
amount of condensation on the inside of the fireplace glass. This is normal and will disappear after 10-20 minutes of operation.
• Your direct-vent gas fireplace system (fireplace and venting) is a
balanced and sealed gas operating unit. It requires approximately 10-20 minutes of operating time before the flame pattern stabilizes.
PRE-INSTALLATION
• Your fireplace is designed to be used in zero clearance installa­tions. Wall or framing material can be placed directly against any exterior surface on the back, sides, or top of your fireplace, except where standoff spacers are integrally attached. If stand­off spacers are attached to your fireplace, these spacers can be placed directly against wall or framing material. See framing details on page 5.
• If you plan on installing a television or entertainment center re­cessed above your fireplace, it is recommended that you main­tain a minimum 18" above top of louver opening.
• When locating termination cap, it is important to observe the minimum clearances shown in Figure 7, page 6.
• If recessing into a wall, you can avoid extra framing by position­ing your fireplace against an already existing framing member.
• Do not recess termination cap into a wall or siding.
• You may paint the termination cap with 450ºF (232ºC) heat­resistant paint to coordinate with the exterior finish.
• There must not be any obstruction such as bushes, garden sheds, fences, decks, or utility buildings within 24" from the front of the termination cap.
• Do not locate termination cap where excessive snow or ice build up may occur. Be sure to clear vent termination area after snow falls to prevent accidental blockage of venting system. When using snow blowers, do not direct snow towards vent termina­tion area.
PREPARATION
LOCATION AND SPACE REQUIREMENTS
Determine the safest and most efficient location for your DESA International direct-vent fireplace. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some common locations. Be aware of all restrictions and precautions before deciding the exact location for your fireplace and termination cap.
When deciding the location of your fireplace, follow these rules:
• Do not connect this fireplace venting to a chimney flue serving a separate solid-fuel burning fireplace or appliance.
• Due to high temperatures, do not locate this fireplace in high traf­fic areas, windy or drafty areas, or near furniture or draperies.
• Proper clearances must be maintained.
• If your fireplace is to be installed directly on carpeting, vinyl tile, or any combustible material other than wood, it must be installed on a metal or wood panel extending the full width and depth of the fireplace. See Figure 3.

VENTING INSTALLATION INSTRUCTIONS

VENTING INSTALLATION INSTRUCTIONS
Installation Precautions

NOTICE: Read these instructions completely be­fore attempting installation.
These models are tested and approved for use with DESA Interna­tional (direct-vent) pipe components and terminations.
The venting system must terminate on the outside of the structure and can not be attached to a chimney or flue system serving a separate solid fuel or gas burning appliance. A direct-vent appliance must have its own venting system. DO NOT common vent this appliance.
These models are approved to be vented either horizontally through an outside wall or vertically through a roof or chase enclosure using the following guidelines:
• When venting system terminates horizontally on an outside wall, you must install a standoff if the termination cap is to be in­stalled directly on a combustible finish such as vinyl, wood, stucco, etc.
• Never run the vent downward as this may cause excessive tem­peratures which could cause a fire.
• V ent pipe air space clearances to combustibles are 1" on all sides except on the horizontal sections, which requires 2" clearance from the top of the pipe. Where the termination cap penetrates a combustible wall, 1" air space clearance is required.
• Snorkel terminations are required when minimum clearance to grade cannot be met (see Figure 16 on page 11).
• Have fireplace and selected vent components on hand to help determine the exact measurements when elbowing or offsetting. Always use wall firestops when penetrating walls and firestops when penetrating ceilings or attic spaces.
• Install horizontal venting with a 1/4" rise for every 12" of run toward the termination.
NOTICE: Failure to follow these instructions will void the warranty.
INSTALLATION PRECAUTIONS
• Wear gloves and safety glasses for protection
• Use extreme caution when using ladders or when on roof tops
• Be aware of electrical wiring locations in walls and ceilings The following actions will void the warranty on your venting
system:
• Installation of any damaged venting component
• Unauthorized modification of the venting system (Do not cut or alter vent components)
• Installation of any component part not manufactured or ap­proved by DESA International
• Installation other than as instructed by these instructions
WARNING: This gas fireplace and vent assembly must be vented directly to the outside. The venting system must NEVER be attached to a chimney serv­ing a separate solid fuel burning appliance. Each direct-vent gas appliance must use a separate vent system. Do not use common vent systems.
WARNING: Vent pipe air space clearances to com­bustibles are 1" on all sides except on the horizontal sections, which require 2" clearances from the top of the pipe. Where the termination cap penetrates a com­bustible wall, 1" air space clearance is required.
WARNING: Read all instructions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life.

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal T ermination
• Vertical Termination
Horizontal Termination Installation
IMPORTANT:
portion of wall firestop. Horizontal installations using round termi­nation require exterior portion of wall firestop available only in vent kit 01491 for V and VV Series or SDHTRK-58 for CHDV Series (see Figure 14, page 10).
1. Set the fireplace in its desired location and determine the route your horizontal venting will take. Do not secure the fireplace until all venting has been installed. Some installations require sliding the fireplace in and out of position to make final vent­ing connections. Figures 14 through 18 on pages 10 through 12 show different configurations for venting with horizontal termination that will help you decide which application best suits your installation. Check to see if wall studs or roof rafters are in the path of your desired venting route. If they are, you may want to adjust the location of the fireplace.
2. Direct vent pipe sections and components are designed with special twist-lock connections.
Twist-Lock Procedure: The female ends of the pipes have
locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes. Push pipe sections together and twist one section clockwise approxi­mately one-quarter turn until the sections are fully locked (see Figure 8). ported every three feet. Use wall straps for this purpose.
3. Use a 45° elbow to connect venting system to fireplace flue col­lar. The elbow is designed to be twist-locked onto the flue collar as described in step 2. configuration of the elbow by cutting, twisting, bending, etc.
4. Assemble the desired combination of pipe and elbows to the fireplace flue collar. If there are long portions of venting run, pre-assembled pipe sections may be installed as subassemblies for convenience.
5. Carefully determine the location where the vent pipe assembly will penetrate the outside wall. The center of the hole should line up with the center-line of the horizontal vent pipe. Mark the wall for a 10 3/4" x 10 3/4" square hole. Cut and frame the square hole in the exterior wall where the vent will be terminated. If the wall being penetrated is constructed of noncombustible material, such as masonry block or concrete, a 8 1/2" hole with zero clearance is acceptable (see Figure 9).
Horizontal square terminations require only inner

6. Noncombustible Exterior Wall: Position the horizontal vent cap in the center of the 8 1/2" round hole and attach to the exte­rior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around the outside edges to make a seal be­tween it and the outside wall. provided should be replaced with appropriate fasteners for stucco, brick, concrete, or other types of sidings.
Combustible Exterior W all: For vinyl siding, stucco, or wood
exteriors, a siding standoff must be installed between the vent cap and exterior wall. The siding standoff prevents excessive heat from damaging the siding materials. Siding material must be cut to accommodate standoff. Bolt the vent cap to the stand­off. Apply non-hardening mastic around outside edge of stand­off. Position the standoff/cap assembly in the center of the 10

SNORKEL TERMINATION INSTALLATION
Recommended Applications:
• Installations requiring a vertical rise on building exterior
• Any installation using snorkel termination to achieve one foot above ground
Snorkel terminations are available for installations requiring a vertical rise on the exterior of the building. If installing snorkel termination below grade, you must provide proper drainage to prevent water from entering snorkel termination (see Figure 16). Do not back fill around snorkel termination.

INSTALLATION FOR VERTICAL TERMINATION
Note:
Vertical restrictor must be installed in all vertical installations.
1. Determine the route your vertical venting will take. If ceiling
joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 19) to avoid cutting load bearing members. lation 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.
2. Set the fireplace in desired location. Drop a plumb line down
from the ceiling to the position of the fireplace exit flue. Mark the center point where the vent will penetrate the ceiling. Drill a small locating hole at this point.
Drop a plumb line from the inside of the roof to the 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 10 3/4" square hole in the ceiling using the locating hole as
a center point. The opening should be framed to 10 3/4"x10 3/4" (273mm x 273mm) inside dimensions, as shown in Figure 9 on page 8 using framing lumber the same size as the ceiling joists. If the area above the ceiling is an insulated ceiling or a room, nail firestop from the top side. This prevents loose insulation from falling into the required clearance space. Otherwise, in­stall firestop below the framed hole. The firestop should be in­stalled with no less than three nails per side (see Figure 20).
Note:
Pay special attention to these instal-

2. Assemble the desired lengths of pipe and elbows necessary to reach from the fireplace flue up through the firestop. Be sure all pipe and elbow connections are fully twist-locked (see Fig­ure 8, page 8).
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 10 actual length may be larger depending on the pitch of the roof. There must be a 1" clearance from the vent pipe to combustible materials. Frame the opening as shown in Figure 9, page 8.
4. Connect a section of pipe and extend up through the hole.
Note:
support the vent pipe every 3 feet. Use wall straps for this purpose (see Figure 19). Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air.
5. Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and fram­ing with roofing nails. Be sure roofing material overlaps the top edge of the flashing as shown in Figure 19. 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 described in Figure 7 on page 6. steep roof pitches. Nearby trees, adjoining rooflines, 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.
7. Twist-lock the vent cap onto the last section of vent pipe.
Note:
floor, including storage spaces and closets, you must enclose pipe. You may frame and sheetrock the enclosure with standard construction material. Make sure and meet the minimum allowable clearances to combustibles. Do not fill any of the required air spaces with insulation.
