SAFETY INFORMATION

WARNINGS

WARNING: This product contains and/or generates chemicals known to the State of California to cause cancer or birth defects, or other reproductive harm.

IMPORTANT: Read this owner’s 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.

PRODUCT FEATURES PRE-INSTALLATION PREPARATION

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 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

Installation Precautions

NOTICE: Read these instructions completely before attempting installation.

These models are tested and approved for use with DESA (directvent) 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 saf ety glasses f or pr otection

• Use extreme caution w hen using lad ders or when on r oof tops

• Be aware of electr ical wir ing loca tions in walls and ceilings The following actions will void the warranty on your venting

system:

• Installation of any damaged venting component

• Unauthorized modif ication of the v enting system (Do not cut or alter v ent components)

• Installation of any component par t not man ufactured or a pproved by DESA

• 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.

IMPORTANT:

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.

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 3/4" square hole and attach to exterior wall with wood screws provided (see Figure 11). The siding standof f must sit flush against the exterior fascia material.

7. Combustible Exterior W all O nly: Slide the wall firestop over the vent pipe before connecting horizontal run to vent cap (see Figure 12).

8. Carefully move fireplace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. The pipe overlap should be a minimum of 11/4".
