#936-50E LOG SET INSTALLATION ATTENTION NOTE CAUTION If converting to LP (propane) gas do so now before installing log set. Follow instructions included with kit. Log numbers are located on bottom of each log. Refer to following instructions and illustrations for proper placement. Do not place logs directly over burner port holes. Improper log placement may affect flame appearance and cause excessive soot to build up on logs and glass.
CONTROL BOARD REMOVAL / INSTALLATION CONTROL BOARD REMOVAL If burner and/or pilot have been burning, use appropriate protection to avoid burns or personal property damage before removing any components. CAUTION 1. Turn gas control knob to OFF. 2. Shut off gas supply at manual shut-off valve. 3. Disconnect gas line flex tube from manual shut-off valve. 4. Disconnect any wall switch, remote control, or thermostat wires from TH/THTP terminals on gas valve. 5. Remove glass assembly. Page 8. 6.

LIGHTING AND SHUTDOWN 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. DUE TO HIGH SURFACE TEMPERATURES, KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. A. This appliance has a pilot which must be lighted by hand.
LIGHTING AND SHUTDOWN (cont.) LIGHTING INSTRUCTIONS 1. Set thermostat to lowest setting, if installed. 2. Turn off all electrical power to appliance. (Fan). 3. Open lower grill to access gas valve & controls. 4. Push gas control knob in slightly and turn clockwise to OFF. 5. Wait five (5) minutes to clear out any gas. Then smell gas, including near the floor. If you then smell gas, STOP! Follow WHAT TO DO IF YOU SMELL GAS safety information below. If you don’t smell gas, go to next step.
LIGHTING AND SHUTDOWN (cont.) TO TURN OFF GAS TO APPLIANCE TURN BURNER OFF To turn burner OFF, depress ON/OFF rocker switch to OFF, turn off wall switch or adjust setting on thermostat or remote control. NOTE The pilot will stay lit. TURN PILOT OFF Turn pilot off by pushing in and turning gas control knob to OFF. DO NOT FORCE. NOTE This control valve has an interlock device. If pilot has been turned off, it cannot be relit until thermocouple has cooled, (approximately 60 seconds).
PRESSURE TESTING IMPORTANT Pressure check taps for manifold (outgoing) and inlet (incoming) pressure have been incorporated into the valve. The pressure tap marked OUT measures outgoing pressure and pressure tap marked IN measures incoming pressure. Follow instructions below for proper testing procedures. The appliance and its individual shutoff valve must be disconnected from gas supply piping system during any pressure testing of that system at pressures in excess of ½ psi (3.5 kPa).
FINALIZING THE INSTALLATION FLAME APPEARANCE: Flame appearance is affected by several factors including altitude, venting configuration and fuel quality. Although the venturi setting has been factory set, adjustments may be necessary for optimal performance and visual aesthetics. When fireplace is first lit, the flames will be blue. Flames will gradually turn yellowish-orange during first 15 minutes of operation.
FINALIZING THE INSTALLATION RESTRICTOR USAGE: Turn fireplace on and allow to burn for 15 minutes. If flames indicate there is excessive draft (flickering, short flames), a restrictor may be necessary. If flames indicate insufficient draft (lifting or ghosting flames), a previously installed restrictor may need to be modified or removed. WARNING TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY, ALLOW FIREPLACE AMPLE TIME TO COOL BEFORE MAKING ANY ADJUSTMENTS AND / OR INSTALLATIONS.
FINALIZING THE INSTALLATION SEASONAL HEAT DUMP This fireplace insert has been manufactured with a heat dump damper located at the inside top of firebox. This allows infinite control over the amount of heat emitted into the living area without affecting flame height. INSTALLER: Please install this fireplace insert with the heat dump in the closed position. HOMEOWNER: This fireplace insert has been installed with the heat dump in the closed position and will operate at its peak efficiency at this setting.
MAINTENANCE The appliance is required to be inspected at least once a year by a professional service person. The compartment below firebox (behind lower grill) must be cleaned at least once a year, more frequent cleaning may be required due to excessive lint from carpeting, bedding materials, or other fibrous materials. It is imperative that the burner be cleaned once a year. NOTE INSTALLATION AND REPAIR SHOULD BE DONE ONLY BY QUALIFIED SERVICE PERSON.
TROUBLESHOOTING CAUTION THE FOLLOWING MUST BE PERFORMED BY A QUALIFIED TECHNICIAN. NO SPARK FROM ELECTRODE TO PILOT WHEN PIEZO BUTTON IS TRIGGERED. A. Check wiring at back of piezo for proper connection. B. Check wiring at electrode for proper connection. C. Check position of electrode (1/8” (3mm) between electrode and pilot). Readjust if necessary. D. Look for arc below electrode and along electrode wire. Direct metal contact may cause an arc below electrode.
TROUBLESHOOTING BURNER WILL NOT LIGHT A. Gas control knob not turned to ON. B. ON/OFF switch not turned on. C. Remote, wall switch or thermostat not turned ON. D. Plugged main burner orifice. E. Remote, wall switch, thermostat, or ON/OFF switch wires defective. Check wires for proper connections. Place jumper wires across terminal at switch. If burner lights, replace defective switch. If switch checks ok, place jumper wires across switch wires on gas valve.
TROUBLESHOOTING PILOT AND BURNER EXTINGUISH WHILE IN OPERATION A. No LP (propane) in tank. ♦ Check tank and refill if necessary. B. Glass frame assembly not installed correctly. ♦ C. Defective thermopile or thermocouple. ♦ D. 1/4” (6 mm) rise per foot is required on horizontal venting. Inner vent pipe leaking exhaust gases back into firebox. ♦ F. Check thermopile and thermocouple for proper millivolts. Improper pitch on horizontal vent. ♦ E.
