  • Page 12: Specific Warnings

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

  • Page 13: 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 water heaters, 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 comply: 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 14: Water Heater Warnings

    Water heater warnings ° To meet commercial hot water requirements, the water heater setpoint is adjustable up to 185°F (85 . How- ever, water temperatures over 125°F (52°C) 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: Pressure Relief Valve

    Firing the water heater without water flow (but filled with water) will cause a boiling noise. The outlet and inlet temperature are checked continuously. The temperature difference must not exceed the pro- grammed value belonging to the actual power mode. If it does, the water heater will go into a lock-out. The applied DHW pump must be controlled only by the Ionic WWH water heater control.
  • Page 18 Hot water could be released when the pressure relief valve is opened. This can result in severe personal injury. Before operating the pressure relief valve manually, check that it will discharge in a safe place. If water does not flow freely from the end of the discharge pipe, turn the gas supply and power OFF and call a qualified person to determine the cause.

  • Page 19: Technical Data Ionic Wwh Water Heaters

    TECHNICAL DATA IONIC WWH WATER HEATERS Functional introduction The Ionic WWH series are water heaters 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.

    10.2 Minimum required pump head. To prevent calcification of the heat exchanger, the flow of the water needs to be high. The design flow of the system should be at a delta T of either 30 or 22.5°F at high fire, depending on the water hardness. To calculate the minimum required pump head, take the resistance of the water heater and add the resistance of the piping and tank to make a good design.

Too large of a differ- ence can indicate a defective pump or a clogged heat exchanger. To protect the water heater, the burner controller reduces the input when the temperature difference ΔT becomes too high: At maximum water heater input ΔT is limited to 32°F (18°C) = (Hx_Diff_DeltaT_Max ) In between 32°F (18°C) and 47°F (26°C) water heater input modulates between minimum and maximum.
