    Specific warnings This boiler is equipped with a pressure switch in the event of a blocked vent; the boiler will lockout. No attempt by the user/owner shall be made to put the boiler back into operation. A qualified service technician must be notified of the issue. The boiler should only be reset by a qualified service technician after they have diagnosed and corrected the issued that caused CAUTION the safety lockout of the boiler.

  • Page 14: To Avoid Injury

    To meet commercial hot water requirements, the tank setpoint is adjustable up to 185°F. However, water temperatures over 125°F can cause severe burns instantly or death from scalds. This is the preferred starting point for setting the control for supplying general purpose hot water. WARNING: Water temperatures over 125 °F (52 °C) can cause severe burns instantly or death from scalding.

  • Page 17: Technical Data Ch Boilers

    4 TECHNICAL DATA CH BOILERS Functional introduction The CH boilers are central heating boilers with a maximum high efficiency. Such a performance can be reached by, amongst other things, using a special heat exchanger made of stainless steel. This allows the flue gases to cool down below the condensation point, and so release extra heat.

The appliance shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain etc.) during installation, operation and servicing. No appreciable drop in line pressure should occur when any unit (or in the instance of a cascade installation when all of the installed units) lights or runs.

  • Page 30: Condensate Drain Connection

    Condensate drain connection The condensate drain is placed at the center and at the bottom of the boiler and has a ¾ inch hose discharge. Connect this flexible hose to the sewer system. Use only plastic parts with the condensate drain. Metal lines are not allowed.
  • Page 31 Flow and return connections Use T-pieces for externally mounting the pressure relief valve and the boiler drain valve for servicing the boiler. We advise to install two service ball valves in the flow and return pipes underneath the boiler, so the boiler can be isolated from the heating system and eventually disconnected, when needed.

  • Page 32: Circulator Functionality

    Chilled Water and Refrigeration Systems The boiler, when used in connection with a refrigeration system, must be installed so the chilled medium is piped in parallel with the boiler with appropriate valves to prevent the chilled medium from entering the boiler The boiler piping system of a hot water boiler connected to heating coils located in air handling units where they may be exposed to refrigerated air circulation must be equipped with flow control valves or other automatic means to prevent gravity circulation of the boiler water during the cooling cycle.

    The use of 50% glycol in the boiler system will result in an increase in the viscosity of the water/glycol mixture and a decrease in the heat transfer. When the boilers are used in a system with 50% glycol the following requirements must be followed at all times.

  • Page 35: Flush The System With Fresh Water

    Flush the system with fresh water The water of the boiler and heating circuit must be free of any particles, debris and pollution. Therefore, the complete installation must always be thoroughly flushed with clean water before installing and using the boiler(s). Plastic piping in the heating system When plastic pipes without oxygen barrier are used in the central heating system, these must be separated from the boiler system by using a plate heat exchanger.

Mount, install, test and maintain the CO detector according to the manufacturer’s instructions. Test the system at least monthly, to ensure the boilers will switch off in case of a CO alarm.

  • Page 71: Existing Common Venting Guidelines

    Existing Common Venting Guidelines. Do not common vent the CH boiler with the vent pipe of any other boiler or appliance. However, when an existing boiler is removed from an existing common venting system, the common venting system is likely to be too large for proper venting of the appliances remaining connected to it.

  • Page 72: Electrical Installation

    12 ELECTRICAL INSTALLATION General  For operation, the boiler needs a dedicated 120 Vac / 60Hz / 15A service.  The boiler mains supply connection is polarity sensitive. L-120 Vac, N-Neutral, PE-Earth ground (Figure 12.2)  The wiring for the connections should be routed at the bottom of the boiler through the wiring knockouts. Separate knockouts are provided for both line voltage and low voltage wiring.

  • Page 73: Additional Safety Limits

    CH call connections to the boiler require a dry contact with no external voltage present. Ensure no external voltage is present on each set of wires before connecting to the boiler. If external voltage is present, the use of an isolation relay is required to prevent damage to the boiler management module.
