21FUTERA FUSION INSTALLATION AND OPERATION INSTRUCTIONSWARNING: Never use an open flame to test for gasleaks. Always use an approved leak detectionmethod. Failure to comply with this warning cancause extensive property damage, severe personalinjury or death!Whenever the gas supply piping is pressure tested theboiler/water heater gas controls must be protected. If thetest pressure is equal to, or less than 1/2 psig, 3.5 kPaisolate the boiler/water heater by closing it’s manual shutoff valve, see Figure 14. If the test pressure is greater than,or equal to 1/2 psig, 3.5 kPa, disconnect the boiler/waterheater and its individual shut-off valve.ELECTRICAL WIRINGElectrical Power ConnectionsCAUTION: Label all wires prior to disconnection whenservicing controls. Wiring errors can cause improperand dangerous operation! Verify proper operation afterservicing.AT T E N T I O N : Au m o m e n t d e l ’ e n t r e t i e n d e scommandes, étiquetez tous les fils avant de lesdébrancher. Des erreurs de câblage peuvent entraînerun fonctionnement inadéquat et dangereux. S’assurerque l’appareil fonctionne adéquatement une foisl’entretirn terminé.The electrical connections to this boiler/water heater mustbe made in accordance with all applicable local codes andthe latest revision of the National Electrical Code, ANSI/NFPA-70. Installation should also conform with CSA C22.1Canadian Electrical Code Part I if installed in Canada.Install a separate 120 volt 15 amp circuit for the boiler/waterheater. A properly rated shut-off switch should be locatedat the boiler/water heater. The boiler/water heater must begrounded in accordance with the authority havingjurisdiction, or if none, the latest revision of the NationalElectrical Code, ANSI/NFPA-70.Line voltage fi eld wiring of any controls or other devicesmust conform to the temperature limitation of type T wireat 95°F, 35°C above room temperature. Use copperconductors with a minimum size of #14 awg.Refer to the wiring diagram supplied with the boiler/waterheater for proper wiring connections.GENERAL OPERATIONWARNING: Before proceeding read and fullyunderstand the instructions contained in thismanual. Do not attempt to operate this boiler/waterheater if it has not been installed in accordancewith the guidelines set forth in this manual. Failureto comply with this warning can result in extensiveproperty damage, severe personal injury or death!Should overheating occur or the gas supply fail to shut off,turn off the manual gas control valve to the appliance. Donot interrupt water fl ow through the boiler/water heater.En cas de surchauffe ou si l’alimentation en gaz ne s’arrêtepas, fermez manuellement le robinet d’arrêt de l’admissionde 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 anddrain valves are closed.Adjust the make-up water pressure regulator so a minimum12 psig, 82.7 kPa system pressure is maintained at thehighest point in the system piping. If a make-up water pumpis used adjust it to maintain a minimum 12 psig, 82.7 kPasystem pressure.Open the boiler piping bleed valves one at a time, topurge the air trapped in the primary and secondaryheat exchanger. Refer to piping drawings (Figures 9 &11) for bleed locations.With the boiler off, run the system pump for at least 30minutes and bleed the system piping using the bleedvalves. If strainers are used in the system piping, the make-up water valve should be closed and the strainers checkedand cleaned.The system expansion tank should be checked to ensurethat the correct water level in the tank is maintained. Thetank should be less than half full of water with the systemfull and adjusted to the correct operating pressure.Star t the boiler as described in the “OPERATINGINSTRUCTIONS” section. Run the boiler for at least anhour. The system pump(s) and all radiation units must beoperated during this time. Ensure that the make-up watervalve is open.Shut the boiler off and open the bleed valves to purge theair trapped in the heating system piping. Close the make-up water valve and check and clean the strainers andmake-up water pressure reducing valve.Open the make-up water valve and adjust the systempressure if necessary. The system should be checked andbled after three days of operation.
