BEFORE YOU BEGIN

Before beginning the installation of your fireplace, read these

instructions thoroughly. This DESA fireplace and its approved

components are safe when installed according to this installation

manual, and operated as recommended by DESA. Unless you use

DESA approved components tested for this fireplace, YOU MAY

CAUSE A FIRE HAZARD!

The DESA warranty will be voided by, and DESA disclaims any

responsibility for the following actions:

A) Modification of the fireplace or any of the components manufac-

tured by DESA unless otherwise permitted in writing by DESA.

B) The use of a fireplace insert or any component part not ap-

proved by DESA in combination with DESA fireplace.

C) Installation and/or operation in a manner other than instructed

in this manual.

D) The burning of any other fuel not tested or approved by DESA

in this wood burning fireplace.

PROPER INSTALLATION is the most important step in ensuring

a safe and continuous operation of this fireplace. Although ground-

ing may not be required by code in your area, it must be electrically

grounded in accordance with local codes or, in the absence of local

codes, with the National Electrical Code, ANSI/NFPA 70-1990.

This fireplace is intended for installation in accordance with the

NationalFireProtectionAssociationStandardforChimneys,Fire-

places,VentsandSolid-FuelBurningFireplaces,NFPA211, and in

accordance with codes such as the BOCABasic/NationalCode, the

Standard Mechanical Code, and the Uniform Building Code.

THISFIREPLACEISNOTINTENDEDTO BEUSEDAS

A PRIMARY SOURCE OF HEAT.

NOTE:

Installation and repair should be done by a qualified

installer familiar with the fireplace. The fireplace and chimney

system should be inspected and cleaned before use and periodically

thereafter especially during heating season to prevent the excessive

buildup of soot and creosote and to ensure a safe operating system.

115603-01A

For more information, visit www.desatech.com

SELECTING LOCATION

To determine the safest and most efficient location for your fire-

place, you must take into consideration the following guidelines:

1. The location must allow for all the proper clearances (see Fig-

ure 2).

2. Consider a location where the heat output would not be af-

fected by drafts, air conditioning ducts, windows or doors.

3. A location that avoids the cutting of joists or roof rafters will

make installation easier.

4. If an outside air kit is to be installed, accessibility to outside

combustion air must be considered. This can also be achieved

through a vented crawl space in some cases, for more details

refer to the section on outside air kit installation.

The typical installation for a (V)3612ST is a projected installation, which

allows you to extend the fireplace any distance into the room. A

projection may be ideal for a new addition on an existing, finished wall.

FRAMING

If the fireplace is to be installed directly on carpeting, tile (other than

ceramic), or any combustible material other than wood flooring, the

fireplace must be installed upon a metal or wood panel extending the

full width and depth of the fireplace.

Construct framing using dimensions shown in Figures 6, 7, and 8,

depending on your particular installation.

Before securing fireplace to prepared framing, the ember protector

(provided) must be placed between hearth extensions (not sup-

plied), and bottom front edge of the fireplace to protect against

glowing embers (see Figure 9, page 6). If the fireplace is to be

installed on a raised platform, a “Z”-type ember protector (not

supplied) must be fabricated to fit your required platform height (see

Figure 8). The ember protector should be made of 28 gauge

minimum, galvanized sheet metal to prevent corrosion.

HEARTH EXTENSIONS

A hearth extension is required to protect the combustible floor

surrounding your fireplace. You may obtain kit No. HE-3612ST or

you may fabricate your own per the dimensions shown on Figure 10.

The hearth extension must project a minimum of 16 inches from the

front of the fireplace and a minimum of 8 inches beyond each side

of the fireplace opening (see Figure 11).

If a hearth extensions is to be field constructed, it must be made of

noncombustible inorganic material having and effective thermal

conductivity “K” of 0.84 BTU In/Ft2 Hr.F or least at 1.0 inch

thickness.

Thermal conductivity “K” of materials can be obtained from the

manufacturer or supplier or the noncombustible material.

The minimum required thickness for any material could be obtained

by the following formula:

K factor x 1.0 inch = Thickness required

0.84

If the hearth extension is to be raised, a “Z” type ember protector

must be used (see Figure 8, page 5, and Figure 12).

OUTSIDE AIR KIT

INSTALLATION

The installation of the outside air kit must be installed during the

rough framing of the fireplace due to the nature of its location.

Outside combustion air can be accessed through an exterior wall or

a vented crawl space (see Figure 13).

CAUTION: Air inlet ducts must not terminate in

attic space.

The maximum height for the air inlet above the platform of fireplace

is a minimum of 3 feet below the chimney cap.

For further details on the installation of the outside air kit, please

refer to the instructions included with the air kit.

CHIMNEY PIPE INSTALLATION

The DESA chimney system is a snap-lock, double wall pipe. It

consists of a stainless steel inner flue pipe(s), a galvanized outer

pipe, and a wire spacer.

Each section of pipe comes in lengths of 12, 18, 36, and 48 inches,

but the actual lineal gain for each is measured after each section is

fully connected. Lineal gain is the actual measurable length of a part

after two or more parts are connected.

Termination

RTL-12D Round Top Termination 7"

PIPE INSTALLATION

Place pipe assembly (inner and outer with wire spacer) over starter

collar. Inner pipe(s) fit inside inner pipe(s). Outer pipe fits outside

outer pipe.

Begin by aligning hemmed end of inner flue pipe into the inner starting

flue pipe of fireplace. Push down until hem “snap-locks” with lances. The

outer pipe is just the opposite, the female end has the lances. Continue the

same procedure for the outer pipe (see Figure 16). It is important to assure

the joints between the chimney sections are fully locked. Check by pulling

chimney upward after locking pipe hem(s). The chimney should not

come apart if properly locked. It is not necessary to add screws to keep

vertical or angled chimney runs together.

Figure 16 - Pipe Connection

WARNING: The opening around the starter collar on

top of the fireplace must never be obstructed. Never use

blown insulation to fill the chimney enclosure.

FIRESTOP SPACERS

Firestop spacers are required at each point where the chimney

penetrates a floor or ceiling joist space. Their purpose is twofold.

They establish and maintain the required clearance between the

outer pipe and combustible materials, they also serve as a shield

between floors as required by most codes.

When penetrating a floor or ceiling at an angle, use firestop spacer

number 30 FS-10D (see Replacement and Accessory Parts,

back page).

When the pipe passes through a framed opening into a living space

above, a firestop must be placed on the ceiling below (see Figure 17,

page 9). When the pipe passes through a framed opening into an attic

space above, a firestop must be placed on the attic floor above (see

Figure 18, page 9).

CAUTION: When using a decorative appliance,

the damper must be removed or permanently locked

in the open position.

WARNING: After ensuring that the gas valve is ON,

test all gas piping and connections for leaks after

installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for

a leak. Apply a noncorrosive leak detection fluid to

all joints. Bubbles forming show a leak. Correct all

leaks at once.

SUPPORT SECTIONS

The chimney support section is a 4-inch strap and 12 inch length of pipe.

A chimney support is required every 30 feet above the fireplace after a

straight chimney run, or above a return elbow after a straight chimney

run (see Figure 20). This support is designed to relieve the extra weight

load on the fireplace and elbows when high chimneys are installed.

To achieve desired offset, you may install combinations of 12, 18,

36, and 48 inch lengths of double wall pipe. See Figure 21 and Rise

and Offset Chart below.

FINISHING YOUR CHIMNEY SYSTEM

10 Foot Rule

All chimney terminations must extend a minimum of 3 feet above

the highest point where it passes through the roof, and must be at

least 2 feet above the roof within a 10 foot horizontal span (see

Figure 23).

IMPORTANT:

If an exposed portion of chimney is greater than 4 feet

above the roof line, use support wires to keep chimney secure. The

support wires may be attached to the outer pipe of the chimney with

screws, provided the screws do not penetrate the inner flue pipe.

Figure 23 - 10 Foot Rule

Figure 22 - Typical Offset Installations

Minimum Chimney Height

The minimum chimney height (measured from bottom of fireplace to

flue gas outlet-end of pipe) is 16 feet for a straight run, 16 feet minimum

for a run with 1 elbow set, and 25 feet minimum for a run with 2 elbow

sets. (A set consists of one starter elbow and one return elbow.)

Uncommon circumstances such as neighboring hills, tall trees, or

strong wind areas can cause down drafts in the chimney system. In

such cases going beyond the minimum recommended height would

be preferable to provide a better draw.

Maximum Chimney Height

The fireplace height approved for any chimney run with this

fireplace system is 40 feet measured from bottom of fireplace to flue

outlet-end of pipe. See Figure 24, page 11

Maximum length of pipe between supports is 6 feet of angled run.

A maximum of two 6 foot angled run sections per chimney system

(See Figure 22).

Chase Installation

Instructions for chase installations are included with the chase style

termination chosen. However, it is worthy to mention here that in a

multiple chase installation, provide adequate distance between

terminations, or smoke spillage from one termination to another

may occur. We suggest terminations be separated at least 30 inches

center to center, and stacked at a vertical height difference of 18

inches vertically from one termination to the other (see Figure 29).

Figure 29 - Chase Clearances

INSTALLING FIREPLACE FACING

Any noncombustible material may be used for facing (glass, tile,

brick, etc.) as long as the proper clearances are adhered to and the

fireplace openings are not obstructed in any way. Refer to Clearances,

page 5, and Figure 30).

Use only heat resistant, noncombustible mortar or adhesive when

securing facing material to the front of the fireplace. When placing

facingat the upper edgeof the effectiveopening of thefireplace, provide

an “L” shaped piece of metal, extending the full width of the opening.

Secure with sheet metal screws at a distance high enough from the

edge as to not interfere with the operation of doors. This assures that

the facing material, in time, should not block the opening if it where

to lose cohesion.

INSTRUCTIONS

GLASS DOORS

Glass doors are optional with the (V)3612ST fireplace. Glass doors

come in cabinet type and BI-fold type. Check with your local

distributor for availability and options.

To install glass doors, refer to the installation instructions that are

included with the glass door kit.

When the fireplace is in operation, all doors must be in the FULLY

OPEN or FULLY CLOSED position only or a fire hazard may be

created (see Figure 31 and 32).

A fireplace equipped with glass doors operates much differently

than a fireplace with an open front. A fireplace with glass doors has

a limited amount of air for combustion. Excessive heat within the

fireplace can result if too large a fire is built or if the combustion air

gate is not completely open.

The following tips should be followed to assure that both the fireplace

and the glass door retain their beauty and function properly.

• Both flue damper and the glass doors must be fully open before

starting the fire. This will provide sufficient combustion air and

maintain safe temperatures in the firebox. If operating with glass

doors closed, do so at this time. Do not operate with doors par-

tially open. Doors must be fully open or fully closed.

• The glass must be allowed to warm slowly and evenly. The tem-

pered glass will withstand a gradual temperature rise to 550 de-

grees Fahrenheit, which is more than other such materials as

pitch laden logs, very dry mill end lumber, large amounts of

paper or cardboard boxes.

• Always keep the fire well back from the doors and never allow

flames to contact the glass.

Cleaning the Glass

Clean glass with any commercial glass cleaner or soap and water.

DO NOT use any abrasive material to clean glass. DO NOT clean

glass with cool water if the glass is still too hot from the fire. To

remove doors, refer to instructions included with glass door kit.

OUTSIDE AIR MECHANISM

The outside air handle is located at the right hand side of the fireplace

rear refractory (see Figure 33). Pull to close, push to open. Always

open the mechanism when starting a fire. This provides adequate

outside combustion air. Close the mechanism when not in use to

prevent cold air from entering the room. Periodically check you’re

outside air intake vent hood for any possible obstructions such as

snow, bushes, etc.

DAMPER MECHANISM

The damper control lever is located inside the fire chamber (see

Figure 33). Make sure lever is cool before handling. Pull down to

CLOSE, push up to OPEN. The damper must be open when lighting

a fire. Not doing so will cause smoke spillage into the room. When

the fireplace is not in use, close the damper to prevent down drafts

to enter the room.

Figure 33 - Damper Operation

GRATE

The grate is designed to provide you with the maximum solid fuel

capacity. Do not attempt to defeat its purpose. Doing so may cause

smoke spillage and a fire hazard. Do not overload the grate or

obstruct the required air space beneath it. Always keep ashes from

building up under the grate.

WARNING: RISK OF FIRE! Replace grate with

DESA model 3610ST-GR grate only.

Never obstruct the flow of combustion and ventilation air. Keep the

front of the fireplace clear of all obstacles and materials.

For further operating guidelines, instructions, and warranty infor-

mation not contained in this owner’s manual, contact your autho-

rized dealer.

WARNING: Childrenandadultsshouldbe alerted

to the hazards of high surface temperatures, and to

stay away to avoid burns or clothing ignition. Young

children should be carefully supervised when they

are in the same room as the fireplace.
