Auto operation ensures there is sufficient heat build-up to warm the air being moved by the blower before the blower is turned on. Likewise, when the appliance cools off, the blower is turned off to prevent circulating cool air. Depending on the size and intensity of the fire it may be necessary to adjust the blower speed accordingly to ensure un-interrupted blower operation. For example a small fire may require a slower blower speed to keep the heat output by the blower consistent. If the blower is operated in manual mode, it may be necessary to adjust the blower speed as the fire begins to burn down and the appliance is no longer hot enough to effectively heat the air moved by the blower. If the air coming from the blower feels cool, one should either decrease the blower speed or stoke the fire to build up more heat. NOTE:Turn blower off before opening the door to load the fuel. Figure 11 -Blower Controls Blower Speed Control Knob (rheostat) Manual / Auto Rocker Switch WARNINGS The blower must be plugged directly into a properly grounded three prongreceptacle,120 VAC,60Hz,single phase. Do not cut or remove the grounding prong from this plug. Do not route power cord under or in front of appliance. Installation must be in accordance with National Elec trical Code, ANSI/NFPA 70 latest edition. In Canada, the current CSA C22-1 Canadian Electrical Code latest edition. DANGER: Disconnect power before servicing blower.

OPERATING TECHNIqUES AND HINTS OPERATING TECHNIqUES AND HINTS GETTING THE MOST OUT OF YOUR FIREPLACE INSERT The following sections will outline techniques you can use to “get the most out of your fireplace insert.” Please read them carefully. MAXIMIzING YOUR FIREPLACE INSERT’S OVERALL EFFICIENCY It is important to know that for high, combustion efficient, clean burns, you will need to have sufficient temperatures inside the firebox for thorough combustion. The best method for determining if you have sufficient temperatures is to watch the brick lining in your firebox. When you first light your fireplace insert, the bricks will turn a dark brown or black. After 20 to 30 minutes of a hot fire, most of the bricks should return to near their original light brown or yellow color. This means the bricks have reached a high enough temperature for your fireplace insert to achieve high combustion efficiency. Second and just as important, is achieving a high level of heat transfer efficiency. Slowing the rate of flow through the stove or insert enhances heat transfer, thus allowing more time for heat to be transferred into your home. To do this, be sure to thoroughly preheat your fireplace insert and then reduce the amount of primary air by closing the draft control (lower left) to about 1/2 to 3/4 open. This will decrease the excess oxygen in your flue, which carries heat up your chimney, but should still be enough air to allow the fireplace insert to produce its maximum heat output. (More air may produce a lightly greater amount of heat, but will greatly increase wood consumption). When the area being heated reaches a comfortable temperature, slow the burn rate by closing the control to further improve heat transfer. To get the most out of your fireplace insert, you will need to combine good combustion efficiency with good heat transfer practices. The following are some tips on how to operate your fireplace insert to achieve the highest overall efficiency. 1. Thoroughly preheat your fireplace insert before slowing the burn rate by closing the draft control. 2. Measure the fireplace insert temperature at the hottest point on the insert top or face. Use this information to repeat burn rates. 3. Once preheated, add wood (if needed) and partially close the draft control (lower left). 4. Operateyourfireplaceinsertasmuchaspossibleinthelowtomedium burn ranges. 5. Do not lower the draft setting so low as to completely extinguish the flames in the firebox. Check for at least some small flames 20 minutes after setting the draft control. 6. Do not continually operate your fireplace insert in the high (wide open) setting. This wastes wood by carrying a great deal of heat up the chimney and can damage your fireplace insert and chimney. 7. Go outside and check your chimney. More than a very small amount of smoke indicates wasted heat, creosote build up and pollution. ACHIEVING CLEAN, LONG BURNS To achieve long burn times, after having thoroughly preheated the fireplace insert, let the insert top cool down to 275 degrees to 400 degrees (on Elites, locate thermometer on the face of the insert just above the door). Now load the firebox and set the draft control. At this ...
