FIREPLACE INSTALLATION
SELECTING LOCATION
To determine the safest and most efficient location for your fireplace, you must take into consideration the following guidelines:
1. The location must allow for all the proper clearances (see Figure 2).
2. Consider a location where the heat output would not be affected 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.

1. To install, remove the knockout indentation on the refractor
(or firebrick) wall located approximately 2 inches above the
refractory hearth floor. The knockout indentation must be firmly
tapped with any solid object until it is released. Remove fragmented portion of refractory (see Figure 14).
2. Remove gas line cover plate on rear of fireplace and pull out insulation from gas line conduit sleeve, save insulation for reuse.
3. Run gas line into the fireplace through the rear at 111/4" from
the floor and through gas line conduit sleeve (if using a raised
platform, add height). Provide sufficient gas line into fireplace
chamber for fitting connection (see Figure 15).
Note: Secure incoming gas line to wood framing to provide rigidity
for threaded end.
4. Repack insulation around gas line and into sleeves openings.
Seal any gaps between gas line and refractory knockout hole
with refractory cement or commercial furnace cement. Install
the decorative gas appliance or cap off gas line if desired.

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.
Note: An appropriate DESA hood (see Replacement and Accessory
Parts, page 16) must be installed when using an unvented gas log set.
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.
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.
CAUTION: When using a decorative appliance,
the damper must be removed or permanently locked
in the open position.

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.

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

Chase Installation
INSTALLING FIREPLACE FACING
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).
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
facing at the upper edge of the effective opening of the fireplace, 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.

OPERATING GUIDELINE AND MAINTENANCE INSTRUCTIONS
Glass Doors
OPERATING GUIDELINES
AND MAINTENANCE
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.
FULLY CLOSED
FIREPLACE FRONT
FULLY OPEN
FIREPLACE FRONT
Figure 31 - Bi-Fold Glass Doors (Top View)
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 partially open. Doors must be fully open or fully closed.
• The glass must be allowed to warm slowly and evenly. The tempered glass will withstand a gradual temperature rise to 550 degrees 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.
WARNING: Fireplaces equipped with glass doors
should be operated only with the doors fully open or
fully closed. Doors left partly open may draw gas (if
used) and flame out of the fireplace opening, creating
risk of both fire and smoke.

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.

DAMPER MECHANISM
GRATE
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.
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.
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.

WARNING: Children and adults should be 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.
For further operating guidelines, instructions, and warranty information not contained in this owner’s manual, contact your authorized dealer.
Figure 33 - Damper Operation
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.
