4 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 ventto an outside/exterior wall(horizontal).Theventpipe installation is very important to allow for proper operation. You must follow the venting instructions very carefully for either vertical or horizontal applications.

Thisfireplacemaybeinstalledinanyroomofyourhouseprovided all local codes and these installation instructions are followed.

This fireplace requires a wall switch, hand-held remote or wall thermostat (millivolt) for operation (see Accessories, page 36).

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 balancedandsealedgasoperatingunit.Itrequiresapproximately1020 minutes of operating time before the flame pattern stabilizes.

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 spacersareattachedtoyourfireplace,thesespacerscanbeplaced directly against wall or framing material. See framing details on page 5.

If you plan on installing a television or entertainment center recessedaboveyourfireplace,itisrecommendedthatyoumaintain 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.

PRE-INSTALLATION 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.

Duetohightemperatures,donotlocatethisfireplaceinhightraffic 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.

Installation Precautions

VENTING INSTALLATION INSTRUCTIONS

NOTICE:Readtheseinstructionscompletelybefore attempting installation.

These models are tested and approved for use with DESA (directvent) pipe components and terminations.

Theventingsystemmustterminateontheoutsideofthestructureand can not be attached to a chimney or flue system serving a separate solidfuelorgasburningappliance.Adirect-ventappliancemusthave its own venting system. DO NOT common vent this appliance.

Thesemodelsareapprovedtobeventedeitherhorizontallythrough anoutsidewallorverticallythrougharooforchaseenclosureusing the following guidelines:

When venting system terminates horizontally on an outside wall, you may 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.

Vent 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.

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.

NOTICE: Failure to follow these instructions will void the warranty.

NOTICE: Do not seal termination cap to vent pipe. Cap must be removable for vent inspection and maintenance.

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

Unauthorizedmodificationoftheventingsystem(Donotcut or alter vent components)

Installation of any component part not manufactured or approved 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.

INSTALLATION PLANNING

There are two basic types of direct-vent installation:

Horizontal Termination

Vertical Termination

Horizontal Termination Installation

IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Horizontal installations using round termination require exterior portion of wall firestop (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.Figures14through18onpages10through12show different configurations for venting with horizontal termination thatwillhelpyoudecidewhichapplicationbestsuitsyourinstallation. 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). Note: Horizontal runs of vent must be supported 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. IMPORTANT: Do not attempt to alter the 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 lineupwiththecenter-lineofthehorizontalventpipe.Markthe 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).

WARNING: Do not recess vent termination into any wall. This will cause a fire hazard.

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. Note: The four wood screws provided should be replaced with appropriate fasteners for stucco, brick, concrete or other types of sidings.

Combustible Exterior Wall: For vinyl siding, stucco or wood exteriors, a siding standoff may 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 standoff must sit flush against the exterior fascia material.

7.Combustible Exterior Wall Only: 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" (see Figure 13, page 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 install-

ing 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.
