SELECTING LOCATION

To determine the safest and most efficient location for your fireplace, consider the following guidelines:

1. The location must allow for proper clearances (see Figure 1).

2. Consider a location where the firepace would not be affected by drafts, air conditioning ducts, windows or doors.

3. A location that avoids the cutting of joists or roof rafters makes ventilation installation easier.

In selecting a location, the following precautions must be observed:

• Do not connect this appliance to a chimney system used for solid

fuel burning fireplace.

• Due to high temperatures, do not locate this appliance in high

traffic areas or near furniture and draperies.

• Never obstruct the openings of the appliance or flow of ventila-

tion air. Keep the control compartments accessible.

• Do not locate appliance close to where gasoline or other flam-

mable liquids may be stored. The appliance must be kept clear and free from combustible materials.

• Do not use this appliance if any part has been under water. Imme-

diately contact a local service technician to examine the appliance and to replace any part(s) of the control ignition system and other related components that have been submerged under water.

VENT TERMINATION CLEARANCES

The final position of your fireplace depends on the location of the vent termination in relation to the clearances that must be observed as shown in Figure 5 on page 5.

The vent system serves as the “chimney” as well as the combustion air supply (air intake). The horizontal run must have a rise of 1/4" (.6 cm) for every 12" (30.48 cm) of horizontal run towards the termination. The maximum horizontal run depends on the vertical rise from the fireplace adapter collar to the vent termination (see table below).

VERTICAL HORIZONTAL

0 to 1 ft (30.48 cm)

1 ft (30.48 cm) to 4 ft (121.92 cm)

2 ft (60.96 cm) to 8 ft (243.84 cm)

3 ft (91.44 cm) to 12 ft (365.76 cm)

4 ft (121.92 cm) to 16 ft (487.68 cm)

5 ft (152.40 cm) to 15 ft (457.20 cm)

6 ft (182.88 cm) to 14 ft (426.72 cm)

7 ft (213.36 cm) to 13 ft (396.24 cm)

8 ft (243.84 cm) to 12 ft (365.76 cm)

FRAMING

Once the final location has been determined, observing height clearances for vent termination, you may construct framing using dimensions shown in Figures 3 and 4, depending on your installation.

If the appliance is to be installed directly on carpeting, tile (other than ceramic), or any combustible material other than wood flooring, the appliance must be installed on a metal or wood panel extending the full width and depth of the appliance.

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. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life.

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

VENTING INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installation. Before installing vent kit, the installer must read this fireplace manual and vent kit instructions.

Only a qualified service person should install venting system. The installer must follow these safety rules:

• 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

• 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 gas appliance must use a separate vent system. Do not use common vent systems.

VENTING INSTALLATION

1. Install elbow to fireplace collar adapter located on back of the unit at a 45° angle. Slide elbow over collar and twist to lock. Check to insure proper connection (see Figure 6).

2. Continue to install remainder of pipe for desired installation. Make sure each section is twist-locked securely.

3. When installation of vent pipe is complete, in stall vent termination. Depending on the location of your fireplace, you will vent vertically or horizontally.

4. Allow 1" of pipe to protrude from internal wall, depending on wall thickness. See Figure 7.

5. For horizontal installation, an optional siding standoff may be installed between the vent cap and the exterior wall. Secure horizontal vent cap to standoff. Secure standoff/vent cap assembly to wall (see Figure 7). Do not seal termination to vent pipe. The vent termination must be removable for service pipe inspection.

6. For vertical installation, a vertical termination is available. Also for vertical venting application, install vertical flue restrictor into inner collar of fireplace as shown in Figure 6.

When installing a length of pipe for vertical termination that is over 3 ft., support the pipe every 3 ft. using metal wall straps. Vertical to horizontal pipe must be kept at a 1 ft. to 4 ft. ratio with a maximum run of no more than 20 ft.

• When used for the first time, the fireplace may emit a slight odor for about 16 to 24 hours. This is normal and is due to the “curing” of the logs and the “burn-in” of internal paint and lubricant used in the manufacturing process.

• Keep compartments, logs, burners and area surrounding logs clean by vacuuming and brushing at least twice a year or as necessary.

• Turn off gas and remote switch before servicing appliance. Any safety screen or guard removed for servicing the fireplace must be replaced prior to operation.

• Have a qualified agency periodically inspect vent system at the start of each heating season for any obstruction which will hinder its normal operation. Never obstruct the flow of combustion and ventilation air. Keep the front of the fireplace clear of all obstacles and materials

FOR YOUR SAFETY

READ BEFORE LIGHTING

WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

A. This appliance has a pilot which must be lighted by hand.

When lighting the pilot, follow these instructions exactly.

B. BEFORE LIGHTING smell all around the appliance area

for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

C. Use only your hand to push in control knob. Never use tools.

If the knob will not push in or slide by hand, don’t try to repair it, call a qualified service technician. Force or attempted repair may result in a fire or explosion.

D. Do not use this appliance if any part has been under water.

Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

CONVERTING FIREPLACE FROM NATURAL GAS TO PROPANE/LP GAS

The conversion kit is packaged with the unit. Please check the contents before beginning this conversion.

WARNING: Before proceeding, make sure the gas control valve is in the OFF position and all electrical power to the appliance is turned off.

CONVERTING PILOT

1. Wait five (5) minutes to clear out any gas. Smell for any gas odor, especially near the floor. If any gas odor is present, STOP! See For Your Safety Read Before Lighting on page 12.

2. Locate the latch on the louver assembly. Remove top and bottom louvers by pulling the spring latches toward the center of the fireplace simultaneously until they are diengaged from the locating holes.

3. Undo latches located on top and bottom of firebox and swing door to the fully open position.

4. Carefully remove log set and ember material from burner and place them aside in a safe place.

5. Replace main burner orifice with burner orifice included in conversion kit (Model CD42M-A series contains two burner orifices).

6. Locate air shutter at end of burner manifold (end of tube burner for CD42M series). Loosen screw and adjust air shutter to proper setting (see Burner Flame Adjustment, page 11). Retighten screw.

7. Remove pilot hood by pulling up until it disengages from barrel. Do not remove the retainer clip (see Figure 34).

8. Remove pilot orifice from inside barrel using a 5/32" allen wrench to unscrew the orifice.

9. Replace pilot orifice with LP orifice supplied with this kit. The number 30 is stamped on the sleeve for identification. Insert small end of new pilot orifice into barrel and thread until tight with the allen wrench.

TROUBLESHOOTING

15 15

OBSERVED PROBLEM

Pilot will not stay lit

Pilot lit but no flame on burner

POSSIBLE CAUSE

1. Defective thermocouple

1. Remote or wires defective

2. Thermopile not generating sufficient milivoltage

3. Plugged burner orifice

REMEDY

1. Check pilot flame. It must impinge on thermocouple

2. Clean or adjust pilot for maximum flame impingement on thermocouple

3. Ensure the connection between valve and thermocouple are tight and secure

4. Check thermocouple with millivolt meter. Take reading at thermocouple terminals of gas valve with remote control off. It should read 18 millivolts minimum. Replace faulty thermocouple if reading is below specified minimum

1. Check remote wires for proper connections. Place jumper wire across terminals at remote control. If burner comes on, replace remote. If okay, place jumper wire across remote control at valve. If burner comes on, wires are faulty or connections are bad

2. Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve with remote control off. It should read 325 millivolts minimum. Replace thermopile if reading is below specified minimum

3. Check burner orifice for stoppage and remove
