GT INSTALLATION AND OPERATION INSTRUCTIONS | Page 29 |
BOILER SET UP
NOTE: Before starting the boiler, turn off the electrical supply going to it. Make sure that gas is available at the gas valve inlet. Open the valves in the hot water return and supply piping. Failure to take these precautions will prevent the boiler from operation properly.
Fill the boiler and all of the radiation with water. Make sure that the system is completely purged of air, see
GENERAL PLUMBING GUIDELINES.
Review these instructions and make sure that the boiler installation complies with ALL of the instructions up to this point.
OPERATING INSTRUCTIONS
The GT boiler employs a pneumatic modulation system. This modulation system increases or decreases the speed of the blower to meet the heating demand. The gas valve pressure regulator senses the air pressure and adjusts the gas flow to ensure correct combustion.
WARNING: Before operating read and under- stand the instructions contained in this manual. Do not attempt to operate this boiler if it has not been installed in accordance with the guidelines set forth in this manual. Read and fully understand the operating instructions in the “For Your Safety Read Before Operating” section of this manual. Failure to comply with this WARNING could result in a fire or explosion causing severe personal injury or death!
Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance.
Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control that has been under water.
NOTE: The GT was tested with Natural Gas having a heating value of 1020 BTU per cubic foot. For areas with lower heating values, a combustion test is required to obtain optimum operation.
WARNING: The input Screw MUST NEVER BE ADJUSTED without verifying proper combustion with a calibrated combustion analyzer. Failure to comply with this warning can result in excessive levels of carbon monoxide which can cause severe personal injury or death!
Table 7 contains the range for the CO, CO2 and NOx that should be in a fl ue gas sample of a properly operating boiler at maximum input.
