When an outside sensor is also connected, the supply temperature will depend on the factory default central heating curve which is sufficient for most applications. OUTDOOR RESET CURVE Factory Default To set your own custom heat curve you will have to set the following parameters. Use the graphs in Figs. 33 and 34 to assist you in the design of the curve. 1. Minimum outside design temperature: Function 8 2. Design Supply water temperature at the minimum design outside temperature: Function 9 3. Maximum outside design temperature: Function 10 4. Design Supply Water Temperature at the maximum outside temperature: Function 11 NOTE: It is important to note that the user can adjust the heat curve down by adjusting the central heating temperature to a lower setting.

Refer to the large wiring diagram provided with your boiler for options installed on your specific unit(s). START-UP Pre Start-up Filling System (Heating Boilers) Fill system with water. Purge all air from the system. Lower system pressure. Open valves for normal system operation, and fill system through feed pressure. Manually open air vent on the compression tank until water appears, then close vent. Air Purge (Domestic Hot Water Heaters) CAUTION: An air vent should be installed at the highest point in the system for proper operation. If water piping is located higher than the boiler, it should be relocated to the highest point in the installed system. Purge all air from system before lighting heater. This can be normally accomplished by opening a downstream valve. Venting System Inspection 1. Check all vent pipe connections and flue pipe material. WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. 2. Make sure vent terminations are installed per code and are clear of all debris or blockage. For Your Safety This appliance has a direct spark igniter. It is equipped with an ignition device which automatically lights the burners. Do not try to light the burners by hand. BEFORE OPERATING, smell all around the appliance area for gas. Be sure to smell near the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS: • Do not try to light any appliance. • Do not touch any electrical switch; do not use any telephone in your building. ± Immediately call your gas supplier from a neighbor’s telephone. Follow the gas supplier’s instructions. ± If you cannot reach your gas supplier, call the fire department. ± Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not turn by hand, do not try to repair it, call a qualified service technician. Forced or attempted repair may result in a fire or explosion. ± Do not use this applianc...
