22Finned copper tube gas boilers – Boiler ManualGENERAL OPERATIONBefore proceeding read and fully understand theinstructions contained in this manual. Do notattempt to operate this boiler if it has not beeninstalled in accordance with the guidelines setforth in this manual. Failure to comply with thiswarning can result in extensive property damage,severe personal injury or death!Should overheating occur or the gas supply fail to shut off, turnoff the manual gas control valve to the appliance. Do notinterrupt water flow through the boiler.En cas de surchauffe ou si l’alimentation en gaz ne s’arrête pas,fermez manuellement le robinet d’arrêt de l’admission de gaz.Hydronic Heating Boilers (Fill System)Open the make-up water valve and slowly fill the boiler andall of the radiation with water. Ensure that all bleed and drainvalves are closed.Adjust the make-up water pressure regulator so a minimum 5psig, 82.7 kPa system pressure is maintained at the highestpoint in the system piping. If a make-up water pump is usedadjust it to maintain a minimum 12 psig, 82.7 kPa pressure atboiler under operating conditions.Glycol systems require a minimum of 20 psig, 137.8kPa at boiler operating conditions.Open the boiler piping bleed valves one at a time, to purgethe air trapped in the primary and secondary heatexchanger. Refer to piping drawings (Figures 10 & 11) forbleed locations.With the boiler off, run the system pump for at least 30 minutesand bleed the system piping using the bleed valves. If strainersare used in the system piping, the make- up water valve shouldbe closed and the strainers checked and cleaned.The system expansion tank should be checked to ensure thatthe correct water level in the tank is maintained. The tank shouldbe less than half full of water with the system full and adjustedto the correct operating pressure.Start the boiler as described in the “OPERATING INSTRUCTIONS” section. Run the boiler for at least an hour. The systempump(s) and all radiation units must be operated during thistime. Ensure that the make-up water valve is open.Shut the boiler off and open the bleed valves to purge the airtrapped in the heating system piping. Close the make-up wa-ter valve and check and clean the strainers and make-up wa-ter pressure reducing valve.Open the make-up water valve and adjust the system pressureif necessary. The system should be checked and bled afterthree days of operation.PROPANE GASPropane gas may not always be detected by smell.Propane gas is heavier than air and can collect inlow areas.Propane gas can ignite or explode if an ignitionsource is present and result in death, serious injuryand property damage!WIRING & CONTROL SET-UPFollow the instructions in the Futera Fusion XLFControl installation and operation instructionmanual shipped with the boiler to wire the boilerand set up the HeatNet control. The control mustbe set up before attempting to fire the boiler.See Figure 15 for location of electrical components.In addition to the information in the Futera Fusion XLF ControlIOM, see the following information on controls and interlocks.CONTROLS & INTERLOCKSLow Water CutoffIf the boiler is to be installed above radiation or if required by othercodes or regulations, install a low water cutoff in appropriate piping.Wire the switch to the “Interlock” contacts as illustrated on “FieldWiring” schematic. Ensure that the low water cutoff device(s) willfunction properly.Operating ControlThe operating control should be set to the lowest setting that willsatisfy the consumer’s needs.Setting the thermostat or operation control too highcan result in scalding resulting in severe personal injury!High Limits (Aquastats)The high limits are located in the top control area of the boiler/water heater. Remote capillary bulbs run to wells on the outlet sideof the supply header. The high limit can be reset by depressing thered button.The water heater high limit should be set to a minimum of 20oF,11oC higher than the operating control. Refer to the HOT WATERSUPPLY section for the proper supply water temperature.Flow SwitchA flow switch is provided in the water outlet piping to prevent theboiler/water heater from firing without adequate water flow throughthe heat exchanger.
