  • Page 9: General Information

    The IGI series water heaters are designed to be installed on or near an outside wall for indoor installation only. The water heater is compact (23 1/2” (59.7 cm) H x 13 5/8” (34.6 cm) W x 8” (20.3 cm) D) and mounts on a wall using the supplied wall bracket. No floor space is needed and the water heater can be mounted at a height convenient for servicing.
  • Page 10: Installation Instructions

    When such locations cannot be avoided, a suitable drain pan must be installed under the water heater.
  • Page 11 2. The water heater must be installed on a wall capable of supporting at least 50 pounds (23 Kg). Locate the water heater at a height convenient for servicing and above the reach of small children.
  • Page 12 24” (61 cm) from the front be provided for servicing. 4. If the water heater is installed in a confined space, such as a closet, ventilation air must be provided to prevent increased room temperature. Excessive ambient temperatures surrounding the water heater may shorten the life of the controls.
  • Page 13 The water is under pressure and may splash. DO NOT reverse the inlet and outlet (cold and hot water) connections on the water heater. This may cause a hazardous operating condition or the water heater may be inoperable WATER QUALITY The EVERHOT®...
  • Page 14: Vwater Connections

    Install a shut-off valve in the cold water supply line. 2. In order to service the water heater in the event the heat exchanger needs to be flushed of lime deposits, tee fittings with shut off valves and service connections to hoses should be installed.
  • Page 15 Recommended Piping for a Basic Installation (Fig. 1)
  • Page 16 Recommended Piping for a Circulation System (Fig. 2)
  • Page 17 The electrical connections for the two solenoids must be tied to the 120 volt main power supply (black and white wires). When the electrical power to the water heater fails, the ¾” solenoid on the cold water inlet pipe closes, stopping water flow into the water heater. The ¼” solenoid opens, allowing the water heater and connected piping to drain.
  • Page 18 Recommended Piping for Back-up Storage System For hotels, motels, and other high flow applications (Fig. 4) Note: The Primary Circulator for the water heating loop must be sized for 21 GPM @ 35 Ft. Head...
  • Page 19 DO NOT thread, plug or cap the discharge line. It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the pressure relief valve.
  • Page 20: Venting

    Such conditions cause sooting or risks of fire and asphyxiation. This water heater is a direct vent design with a single coaxial vent tube in which the flue products are discharged to the outdoors through the center flue tube and combustion air from outdoors is taken through the outside intake air pipe surrounding the center flue exhaust pipe.
  • Page 21 VENT/AIR INTAKE TERMINAL LOCATIONS Direct Vent Terminal Location Plan the vent system layout so that proper clearances are maintained from plumbing and wiring. Before the vent is installed, determine the vent pipe termination location as shown below in the Vent Terminal Location illustration.
  • Page 22 Vent pipes serving power vented appliances are classified by building codes as “vent connectors”. Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATION OF WATER HEATER and CLEARANCES, and with National Fuel Gas Code and local codes.
  • Page 23 Bradford White supplier for additional venting components illustrated at the back of this instruction manual. If the vent termination height above the water heater exceeds 5 feet (1.5 m), then a condensate collector (available from your Bradford White supplier) will be required within 5 feet of the vent connection of the water heater to collect condensate from the vent pipe.
  • Page 24 When installing a “Standard Vent Discharge Kit” to vent directly out the wall to the back of the water heater, these brackets should be adjusted so that the water heater is moved out the maximum 2” (5.1 cm) away from the wall. Before cutting the vent terminal to the required length, ensure that the distance the water heater is away from the wall has been accounted for.
  • Page 25 If the height of the vent pipe is extended 5 feet (1.5 m) or more above the top of the water heater, then a condensate collector must be used. Refer to the parts list at the end of this instruction manual and the Venting System Installation Instructions supplied with the water heater for available venting components and detailed instructions on fitting the components together.
  • Page 26 Fig. 6 Vertical Direct Vent Installations The EVERHOT® IGI series water heater can also be installed to vent vertically through the roof using a vertical discharge adaptor, optional vent extension tubes, a condensate collector, a roof terminal, and a universal lead tile. In addition to the total equivalent feet limit of 41 feet (12.5 m), the maximum height of the venting system is limited to 21 feet (6.4 m).
  • Page 27 5 feet (1.52 m) of the water heater vent connection. The Condensate Collector must be located within 5 feet (1.52 m) of the water heater vent connection. A trap must be installed after the condensate connection to prevent flue products from leaking into the room.
  • Page 28 Combustion Blower Dip Switch Settings for Vent Length Compensation Under 22 Feet (6.7 m): To assure optimum efficiency and reduced noise levels, the combustion blower switch has two dip switch settings. Dip switch number 1 (top dip switch) is shipped from the factory set to the OFF position to compensate for the maximum vent/air intake length.
  • Page 29: Gas Connections

    SECTION VII: GAS CONNECTIONS Connect this water heater only to the type of gas as shown on the rating plate. Use clean black iron pipe or equivalent material approved by local codes and ordinances. (Dirt and scale from the pipe can enter the gas valve and cause it to malfunction).
  • Page 30 GAS METER SIZE –NATURAL GAS ONLY Be sure that the gas meter has sufficient capacity to supply the full rated gas input of the water heater as well as the requirements of all other gas fired equipment supplied by the meter. If the gas meter is too small, ask the gas company to install a larger meter having adequate capacity.
  • Page 31 L.P. Gas: 4.2” w.c. High Fire, 0.9” w.c. Low Fire 6. Turn off the hot water faucets. Disconnect the electrical power to the water heater. Remove the pressure gauges and replace the plugs. Check for gas leaks around the plugs.
  • Page 32: Electrical Connections

    National Electrical Code, ANSI/NFPA 70 and/or CSA C22.2 Electrical Code. The water heater must be wired to a 120 VAC, 60 Hz, 15A power supply. The water heater should be connected to a GFI outlet and wired on a separate circuit and breaker. If a flexible line cord and plug is permitted by local code, then provide a three wire GFI grounding type receptacle within reach of the control box.
