Safety Information Continued DANGER: Carbon monoxide poisoning may lead to death! Before beginning the installation of the fireplace, read these instructions through completely. • This DESA fireplace and its components are safe when installed according to this installation manual. Unless you use DESA components, which have been designed and tested for the fireplace system, you may cause a fire hazard.
Safety information Continued WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner flame patterns. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies. Do not place clothing or other flammable material on or near the appliance. Never place any objects on the appliance. Do not use this fireplace to cook food or burn paper or other flammable material. This fireplace reaches high temperatures.

Venting Installation Instructions 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. WARNING: Seal all connections with high temperature silicone every time a vent connection is made. Before joining elbows or pipes, apply a bead of high temperature silicone sealant to the male end of the elbow or pipe.
Venting Installation instructions Continued Your DESA direct-vent fireplace has been tested for a minimum 3' rise with a maximum 11" wall thickness. Any horizontal application longer than 12" must provide a minimum of 1 foot of vertical rise for every 3 feet of horizontal run. The maximum horizontal run is 20' with 8' vertical rise (see Installation for Horizontal Termination). The maximum vertical run is 30' (see Installation for Vertical Termination, page 114).
Venting Installation instructions Continued Twist-lock Procedure: The female ends of the pipes and fittings have four locking lugs (indentations). These lugs will slide straight into matching slots on the male ends of adjacent pipes and fittings. (All connections must be sealed with high temperature silicone sealant as specified in the second warning statement on page 10.) Push the pipe sections together and twist one section clockwise approximately one-quarter turn until the sections are fully locked.

Venting Installation Instructions Continued installation for vertical Termination NOTICE: Use rigid pipe only. Flex venting is not to be used with a vertical termination. 1. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 21) to avoid cutting load bearing members.
Venting Installation Instructions Continued 2. Assemble the desired lengths of pipe and elbows necessary to reach from the fireplace flue up through the firestop. All connections must be sealed with high temperature silicone sealant as specified in the second warning statement on page 11. Be sure all pipe and elbow connections are fully twist-locked (see Figure 14, page 12 ). 3. Cut a hole in the roof using the locating hole as a center point. (Cover any exposed open vent pipes before cutting hole in roof.

Installation Continued IMPORTANT: The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig. (3.5 kPa). The appliance must be isolated from the gas supply piping system by closing its individual equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig. (3.5 kPa). CAUTION: Do not kink flexible gas line.

Figure 45 shows top view of burner and grate. 6. Place logs “A” as shown in Figure 46. 7. Place logs “B” as shown in Figure 47, page 23. Lift end of log “A” that will be propped up and place log “B” under it. At the same time, the other side of log “B” is placed over other log “A”. Repeat procedure for other log “B”.
Installation DECORATIVE FACING Continued 8. Take twigs “C” (shaped like a “Y”) and place them as shown in Figure 48. 9. Take twigs “D” (bent twig) and place them as shown in Figure 48. 10. Place twig “E” across the top of logs “B” as shown in Figure 48. 11. When finished installing logs, close glass door. Make certain safety door switch is fully depressed by door frame before securing four (4) spring loaded latches. 12. Replace louvers in reverse order with grilles pointing in down position.
Pilot/Electrode Assembly Adjustment Continued The electrode is installed at the factory for proper positioning. However, alterations to the position may have occurred due to shipping and handling. These settings may need adjustment and must be done by a qualified technician. The correct position and height is as shown in Figure 50. 3/4" (19 mm) CORRECT INCORRECT CLOSE SHUTTER Long, Blue Flame with Yellow Tips Short, Sharp, Blowing Flame INCORRECT OPEN SHUTTER 1/2" (12.
Burner Flame Adjustment Continued 5. To reinstall burner, follow reverse steps making sure air shutter on burner tube is completely seated over orifice mount. 6. Replace log set. Close door and latch. Reattach screen and louvers. CAUTION: Make certain orifice is fully inside venturi tube's air shutter and that air shutter is adjusted accordingly, see Figure 50, page 24. Cleaning and Maintenance When lit for the first time, the appliance may emit a slight odor for about 16 - 24 hours.
Cleaning and Maintenance Continued 3. If replacement is necessary, the entire assembly (frame and glass) must be replaced. If glass is broken, wear gloves and tape remaining fragments onto the frame. Remove 5 screws located on end of firebox while holding frame assembly to prevent it from falling and causing injury (see Figure 54). Mount new frame at hinge with 5 new screws. Close and latch door. This will seat the gasket.
OPERATING FIREPLACE Continued 6. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information, page 28. If you don’t smell gas, go to the next step. 7. Turn knob on gas control counterclockwise to PILOT. 8. Push in the control knob all the way and hold in. Immediately light the pilot by pressing the ignitor button until a flame appears 1 minute after the pilot is lit. The pilot is located by the main burner.
OPERATING FIREPLACE Continued 5. Smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information, page 27. If you don’t smell gas, go to the next step. 6. Turn main burner wall switch to the ON position for ignition. There will be a spark at the electrode. The electrode is located by the main burner. 7. Replace control access panel or louver once there is a flame at the burner.
Troubleshooting WARNING: Turn off heater, disconnect power if applicable and let cool before servicing. Only a qualified service person should service and repair heater. CAUTION: Never use a wire, needle, or similar object to clean pilot. This can damage pilot unit. Note: The two most common causes of malfunctioning gas appliances are loose wiring connections and construction debris clogging pilot and/or control valve filter. Note: Before troubleshooting the system make sure gas shut off valve is open.
TROUBLESHOOTING Continued PROBLEM POSSIBLE CAUSE REMEDY When ignitor button is pressed, 1. Defective ignitor there is no spark at pilot 1. Replace ignitor if wire is properly connected and you have no spark 2. Defective pilot or misaligned 2. Using a match, light pilot. If pielectrode at pilot lot lights turn off pilot and push piezo again. If pilot lights, an improper gas/air mixture cause improper lighting and a longer purge period is recommended.
TROUBLESHOOTING Continued PROBLEM POSSIBLE CAUSE REMEDY 1. Loose wiring on ignition 1. Check ignition wire connection (see Wiring Diagrams) module 2. Poor ground to ignition 2. Check ground wire connection (see Wiring Diagrams) module 3. Main burner flame too low 3.
