Page 4: Introduction
INTRODUCTION The Lochinvar Herald range is a floor standing gas fired condensing boiler. The equipment comprises a stainless steel radial burner assembly and a heat exchanger that permits fully condensing operation. The burner is initiated by a full electronic ignition sequence control that incorporates a spark ignition and a flame rectification device for supervision of the flame. -
Page 5: Safety Guidelines
SAFETY GUIDELINES READ AND UNDERSTAND THE INSTRUCTIONS Read and fully understand all instructions before attempting to operate maintain or install the unit. Keep these instructions near the Boiler for quick reference. This equipment must be installed by a competent person, registered with the H.S.E. approved body. All installations must conform to the relevant Gas Safety and Building Regulations. -
Page 6: What To Do If You Smell Gas
Do not re-enter the building until it is safe to do so Lochinvar limited is not liable for any damage caused by inaccurately following these mounting instructions. Only original parts may be used when carrying out any repair or service work. -

GENERAL REQUIREMENTS The Lochinvar Herald condensing boiler has been designed to operate trouble free for many years. These instructions should be followed closely to obtain the maximum usage and efficiency of the equipment. READ AND UNDERSTAND THE INSTRUCTIONS Read and fully understand all instructions before attempting to operate maintain or install the unit. -
Page 13: Water Quality
WATER QUALITY The Lochinvar Herald contains a stainless steel heat exchanger; therefore, care must be exercised to ensure that the system water and any water treatment are compatible. Whenever a new boiler is connected to an existing system, the pipework must be thoroughly cleaned and flushed to remove debris, rust particles, carbonate deposits and any existing water treatment that might be incompatible with the heat exchanger. -
Page 14: Clearances
GAS SUPPLY The Lochinvar Herald range is suitable for use on second and third family gasses 2H - G20 - 20mbar and 3P - G31 - 37mbar. For details relating to Propane (3P) please refer to Section on LPG FUEL: 9.1 SERVICE PIPES... - Page 15 EQUIPMENT GAS SYSTEM LEAK CHECK An approved gas-inlet appliance isolating valve and union should be installed for each unit in a convenient and safe position and be clearly marked. Ensure that the gas-inlet appliance isolating valve is in the OFF position. Although the equipment receives a gas leak check and gas train component integrity check prior to leaving the factory, transit and installation may cause disturbance to unions, fittings and components.

Page 76: Dhw Settings
21.5 DHW SETTINGS 21.5.1 DHW T OINT By installing a tank sensor, the SMART SYSTEM control can perform the tank thermostat function. The SMART SYSTEM control automatically detects the presence of this sensor, and generates a DHW call for heat when the tank temperature drops below the tank set point differential (Tank Set point Differential parameter), and finishes the call for heat when the tank temperature reaches tank set point. - Page 77 21.5.10 DHW T PEED IMITING FOR NDIRECT This parameter determines the maximum fan speed (and therefore the maximum kW rate) to be used when heating an indirect DHW tank. This setting may be used when the tank is unable to accept all of the kW available from the boiler.

Page 81: Ramp Settings
21.8 RAMP SETTINGS Please note that the brackets ([]) denote screen status. The SMART SYSTEM control can be programmed to limit the firing rate for a fixed period of time at the start of a space heating or BMS set point demand. There are six (6) possible limits, each with their own time delay. The first limit applies as soon as the burner starts. - Page 82 21.9.5 ASCADE IFFERENTIAL This parameter determines how much the temperature must go below the turn off temperature (Set point + Offset) before the lead boiler turns on. This parameter can be adjusted by the installer by accessing the Cascade Differential parameter.
-
Page 83: Building Management System (Bms)
21.9.10 LTERNATE EADER This parameter allows the Member 1 boiler to automatically assume control of the Cascade should it lose communication with the Leader boiler. When programmed to YES, it is recommended that the Member 1 boiler have its own set of external sensors installed (such as the system supply sensor), to maintain the same level of temperature control as with the Leader boiler. - Page 84 21.10.3 ATE AT INIMUM OLTS When programmed for BMS control through the 0 - 10V BMS input or through ModBus/BACnet and the BMS Type is programmed as POWER, the modulation percentage represented by the Volts at Minimum parameter is set by the Rate at Minimum Volts parameter.

21.10.11 IFFERENTIAL OLTS When programmed for BMS control through the 0 - 10V BMS input or through ModBus/BACnet and the BMS Thermostat Input is set to INACTIVE, the Off Differential Volts parameter determines how far below the On Volts setting the 0 - 10V BMS input voltage must be in order to disable the boiler. The minimum value is 0.2V and the maximum is the On Volts setting. -
