The flame should be blue in color around the pilot hood, with traces of yellow toward the outer edges. The pilot flame should engulf the top 3/8” of the thermopile (to generate millivolt current) and the top 1/8” of the thermocouple. The pilot flame should project out of the pilot hood 1” at all three ports. See fig. 37. 3. BURNER ADJUSTMENT: This stove is equipped with a variable gas control valve that allows easy adjustment of the flame height appearance and heat output. To adjust the flame between the HI and LOW setting, rotate the HI/LOW knob, located in the center of the valve face. Flame height will adjust approximately 1” to 2” between the LOW and HIGH settings. See fig. 38. NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG PLACEMENT IF ANY SOOT OR SMOKE IS PRESENT. IF SOOT OR SMOKE PERSISTS, THE AIR SHUTTER MAY NEED TO BE ADJUSTED. See Air Shutter/Flame Appearance section of this manual for proper air shutter settings and adjustments. Note: the more offsets there are in the vent system, the greater the need for an air shutter adjustment. See page 20. WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN. Figure 37. Proper pilot flame appearance. CAUTION: DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE BY POSITIONING THE GAS VALVE CONTROL IN ANY OTHER POSITION OTHER THAN THE FULL “ON” POSITION. Figure 38. Flame appearance on the “high” setting after approximately 15 to 20 minutes burning. Operation Familiarize yourself with the controls of the GF 400 DV Sebago. Make sure that anyone else using the appliance is also familiar with the controls and operation procedures. Always follow the Lighting Instructions on the inside back cover of this manual and also located on the Rating Plate attached to the back of the stove. 1. Once the pilot is lit, burner operation is controlled by the rocker switch located at the left rear corner of the stove. Use the T-STAT position for the optional thermostatic or remote control functions. See fig. 39. 2. During the first few fires, you may notice odor and/or smoke from the stove. This is normal and results from burn-off of manufacturing residue and curing of materials. You may find it helpful to provide additional ventilation and fresh air to alleviate this condition. 3. Condensation may occur on the glass upon each lighting of the appliance. This “fog” will disappear as the appliance heats up. 4. Keep the controls and the area under the appliance free of debris, vacuum this area frequently. Always keep the appliance area clear and free from combustible materials, gasoline and other flammable liquids. If a vacuum is used during any service on the stove, ALWAYS be sure the stove is cold and there are NO hot embers. 5. Remember, this appliance has a continuous burning pilot flame. Exercise caution when using products having combustible vapors. Always shut-off gas supply while servicing the stove. 6. CAUTION: DO NOT OPERATE THIS APPLIANCE WITH THE GLASS REMOVED CRACKED OR BROKEN. Replacement of the glass should be done by a licensed or qualified service person. Use only replacement glass provided by your authorized Jotul dealer. Never use any substitute materials. WARNING: OBSERVE CAUTION WITH THE GLASS. THE GLASS PANEL MAY SHATTER UNEXPECTEDLY IF STRUCK WITH AN OBJECT. ALWAYS HANDLE THE GLASS PANEL WITH CARE. WHEN SERVICING THE STOVE ALWAYS PULL THE GLASS ASSEMBLY STRAIGHT UP FOR REMOVAL. 7. Clean the glass only when necessary. Wipe surface with a clean, damp soft cloth. Follow with a dry, soft towel as desired. Take care not to scratch the glass surface. WARNING: DO NOT USE ABRASIVE CLEANERS ON THE GLASS. NEVER CLEAN THE GLASS WHEN IT IS HOT. Figure 39. Burner Switch and Optional Blower Controls Maintenance Your Jotul GF 400 DV Sebago and its venting system should be inspected before use and at least annually by FOR REPLACEMENT, USE ONLY JOTUL CERAMIC GLASS PANEL 220089. DO NOT USE ANY OTHER TYPE OF GLASS WITH THIS APPLIANCE. a qualified service technician. Use the form on page 30 to keep a maintenance history of your stove. IMPORTANT: ALWAYS TURN OFF THE GAS SUPPLY TO THE FIREPLACE AND UNPLUG THE FORCED AIR BLOWER BEFORE ANY SERVICE WORK IS PERFORMED ON THE FIREPLACE. Annual Cleaning Vent System The entire vent system, including the chimney, should be inspected and cleaned every year. If the intake and exhaust venting is disassembled for any reason, it should be reassembled and sealed according to the manufacturer’s instructions provided at the initial installation. Burner and Logset Periodically inspect the Firebox, Valve Compartment, Convection Airways and optional Blower to BE CERTAIN THAT THE FLOW OF COMBUSTION AND VENTILATION AIR IS UNOBSTRUCTED. The firebox should be vacuumed annually to remove any surface build up. Use a soft brush attachment and handle the logs carefully as they are fragile. Be sure to vacuum or wipe off the pilot assembly and burner surfaces. Glass Care Clean the glass only when necessary. Wi...
