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

  • Page 14: Warning For Water Heaters

    Warning for water heaters 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.

  • Page 15: For Installations In The Commonwealth Of Massachusetts

    For installations in the Commonwealth of Massachusetts The following local requirements apply in addition to all other applicable NFPA requirements: For direct- vent boilers, mechanical-vent heating appliances or domestic hot water equipment, where the bottom of the vent terminal and the intake is installed below four feet above grade the following requirements must be met: 1) If not present on each floor level where there are bedrooms, a carbon monoxide detector and alarm must be placed in a living area outside the bedrooms.

  • Page 17: Technical Data Ionic Fcb / Fwh

    TECHNICAL DATA IONIC FCB / FWH Functional introduction The Ionic is a central heating (FCB) boiler or domestic hot water (FWH) heater 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.

    High altitude operation. High Altitude Operation The boiler / water heater is designed to operate at its maximum listed capacity in installations at elevations less than or equal to 2000 ft (610 m) above Sea Level. Since the density of air decreases as elevation increases, maximum specified capacity will be de-rated for elevations above 2000 ft (610 m) in accordance with the table underneath.

  • Page 34: Central Heating Boiler

    CENTRAL HEATING BOILER Flow and return connections When using a boiler circulator, this circulator should always be mounted in the return pipe of the heating system. Do not use chloride-based fluxes for soldering any pipes of the water system. It is recommended to install service valves, so the boiler can be isolated from the heating system, when needed. Make sure that the pressure relief valve is mounted between the boiler and the service valves.

  • Page 35: Chilled Water And Refrigeration Systems

    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 pre- vent gravity circulation of the boiler water during the cooling cycle.

    Water quality The pH value is reached with steady conditions which Contaminant Maximum allowable Units will occur, when after filling the heating system (pH level around 7) with fresh water, the water has lost its air 7.5 to 9.5 because of the air bleeding operation and heating up 50 to 150 ppm CaCO (dead water conditions).

  • Page 37: Use Of Glycol

    Use of glycol To prevent the system from freezing, the use of mono propylene glycol can be considered. All materials, used in the boiler, are resistant to mono propylene glycol. Never use Ethylene glycol in a heating system as it is toxic and can damage gaskets.

  • Page 38: Chemical Water Treatment And System Cleaners

    Chemical water treatment and System Cleaners The chemical compatibility of several products for treatment of the central heating equipment has been tested on the heat exchangers and the boilers. See table 9.4 for the list with the corrosion inhibitors in preventative and curative treatment for gas fired central heating boilers.

  • Page 39: Plastic Piping In The Heating System

    Plastic piping in the heating system When plastic pipes without oxygen barrier are used in the central heating system, these should be separated from the boiler system by using a plate heat exchanger. Diffusion (through the plastic) can cause air to enter the heating system. This could damage the boiler, circulators and other components in the system.

  • Page 40: Modulating Circulator For Ch Demand

    Modulating circulator for CH demand When using a modulating circulator with the boiler it can be connected using PWM modulation or 0-10V modulation. Parameter 136 has to be set to modulating (Factory set to on/off circulator) when using a modulating circulator. The boiler circulator is modulated when there is a demand for CH.

  • Page 42: Water Heater

    WATER HEATER Water quality In direct water heating appliances, tap water flows directly through the heat exchanger of the water heater. Because all the time fresh water, containing dissolved minerals, is heated, scaling may occur. To prevent this, water quality must meet a number of standards.

  • Page 43: Installation Instructions

    Pipework must be made of copper or stainless steel pipes. Piping diameters must meet the minimum sizes or larger required in table 10.2 based on the water heater model and water hardness. The applied circulator must be a bronze or stainless steel circulator and controlled only by the FWH water heater control.

  • Page 44: Cascade Setup

    10.5.2 C ASCADE SETUP The FWH water heater can operate in cascade. Every water heater should have its own circulator, no additional circu- lators are needed. Pipe sizes to be used depend on the number and type of water heaters, and the number and type of water tanks.

    15.9.5 CH ; CH WITH ANALOG INPUT CONTROL OF SETPOINT MODE In mode 4, the boiler CH setpoint is controlled by an analog input signal provided by a remote means such as a Building Management System or a system controller. The analog input 0-10 Vdc is used to adjust the boiler setpoint between the CH_Min_Setpoint and the CH_Max_Setpoint settings.
