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 6.

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

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.

WARNING: Horizontal sections of this vent system require a minimum clearance of 2" from the top of the pipe and 1" minimum to the sides and bottom.

Vertical sections of this system require a minimum of 1" clearance to combustible materials on all sides of the pipe.

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, page 8.

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, page 8). 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, page 7.

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.

If an offset is necessary in the attic to avoid obstruction, it is important to support the vent pipe every 3 ft. to avoid excessive stress on the elbows and possible separation

(see Figure 8).

Clearances must be maintained between the roof and the termination. Refer to chart below.

OPERATING FIREPLACE

OPERATION GUIDELINES

• 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.

WARNING: Turn off heater and let cool before servicing. Only a qualified service person should service and repair heater.

OBSERVED PROBLEM

Pilot will not stay lit

Pilot lit but no flame on burner

Frequent pilot outage

POSSIBLE CAUSE

1. Defective thermocouple

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. Remote or wires defective

2. Thermopile not generating sufficient milivoltage

3. Plugged burner orifice

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

1. Pilot flame may be too low or blowing (high) causing safety pilot to “drop out”

1. Clean and/or adjust pilot flame for maximum flame impingement on thermocouple
