  • Page 7: Part 1 - General Safety Information

    PART 1 – GENERAL SAFETY INFORMATION A. PRECAUTIONS This appliance is for indoor installations only. Clearance to combustible materials: 0” top, bottom, sides and back. Unit must have room for service: 24” front and 12” sides are minimum recommended service clearances.

  • Page 8: Part 2 - How The Heater Operates

    Condensate neutralizers are made up of lime crystals, marble or phosphate chips. Neutralizers can be installed in the field by the installer and purchased from HTP (p/n 7450P-212). It is also very important not to expose the condensate line to freezing temperatures or any type of blockage.

  • Page 9: Part 3 - Prepare Water Heater Location

    allow condensate to drain properly. Support of the condensation line may be necessary to avoid blockage of the condensate flow. Spark Ignition The burner flame is ignited by applying high voltage to the system spark electrode. This causes a spark from electrode to ground.

  • Page 10: Clearances For Service Access

    C. CLEARANCES FOR SERVICE ACCESS Figure 1 If you do not provide the minimum clearances shown, it might not be possible to service the heater without removing it from the space. The space must be provided with combustion/ventilation air openings correctly sized for all other appliances located in the same space as the heater.

  • Page 11: Direct Vent Installation Of Exhaust And Intake

    Vents must be properly supported. Heater intake and exhaust connections are not designed to carry heavy weight. Vent support brackets must be within 1’ of the heater and the balance at 4’ intervals. Heater must be readily accessible for visual inspection for the first 3’ from the heater. 1.

  • Page 12: Prevent Combustion Air Contamination

    Do not attempt to vent this appliance by any means other than those described in this manual. Doing so will void the warranty, and may result in severe personal injury or death. Failure to provide an adequate supply of fresh combustion air can cause poisonous flue gases to enter living space, which could result in severe personal injury or death.

  • Page 13: Water Chemistry

    When removing an existing heater, follow the steps below. 1. Seal any unused openings in the common venting system. 2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is blockage, leakage, corrosion or other deficiencies that could cause an unsafe condition.

    number. The minerals in the water precipitate out when the water is heated and cause accelerated lime and scale accumulation on a heat transfer surface. If the hardness of the water exceeds the maximum level of 25 grains per gallon, water should be softened to a hardness level no lower than 5 grains per gallon.

  • Page 15: Part 5 - Heater Piping

    PART 5 – HEATER PIPING Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or heater. Use only copper or brass fittings. Teflon thread sealant must be used on all connections. A. GENERAL PIPING INFORMATION Use two wrenches when tightening water piping at heater.

  • Page 16: Temperature And Pressure Relief Valve

    C. TEMPERATURE AND PRESSURE RELIEF VALVE To avoid water damage or scalding due to relief valve operation: • Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge.

  • Page 17: Water Piping

    Undersized expansion tanks cause system water to be lost from the relief valve, causing make-up water to be added. Eventual heater failure can result due to excessive make-up water addition. SUCH FAILURE IS NOT COVERED BY WARRANTY. 2. The expansion tank must be located as shown in the Heater Piping Details, or following recognized design methods.

    The heater has the capability of an outdoor reset. Connecting an outdoor sensor allows the heater to operate at optimum efficiency. HTP offers an outdoor sensor, p/n 7250P-319 The outdoor sensor must be a 12K NTC sensor. Use a minimum 22 AWG wire for runs of 100 feet or less and minimum 18 AWG wire for runs up to 150 feet.

  • Page 41: Condensate Removal System

    If the heater condensate outlet is lower than the drain, you must use a condensate removal pump (kit p/n 554200 available from HTP). If required by local authorities, a condensate filter of lime crystals, marble, or phosphate chips will neutralize slightly acidic condensate. This can be installed in the field and purchased from HTP (p/n 7450P-212).

  • Page 42: Part 9 - Start-Up Procedure

    Plastic pipe must be the only material used for the condensate line. Steel, brass, copper or other materials will be subject to corrosion or deterioration. A second vent may be necessary to prevent a condensate line vacuum lock if a long horizontal run is used. An increase in condensate line diameter may be necessary to allow condensate to drain properly.
