  • For an external electrical source, ground this unit in accordance with

National Electrical Code ANSI/NFPA70.

Your Atwood gas water heater is now ready for operation. Continue to HOW TO OPERATE YOUR WATER HEATER.

Electronic Ignition continue to Electronic Ignition WIRING INSTRUCTIONS. Pilot Relight continue to Pilot Relight WIRING INSTRUCTIONS.

For HEAT EXCHANGE continue —

  • 1.

    Push 5/8˝ dia. 2 or 3 coolant system hose with SAE 053 A Type “E”clamp attached (FIG 6-E) onto heat exchange tube as far as possi- ble (FIG 6-B).

  • 2.

    Spread hose clamp and slide toward heat exchange unit past annular groove (FIG 6-C) and release.

  • 3.

    Continue to HOW TO OPERATE YOUR WATER HEATER and/or Electronic Ignition OPERATION.

For COMBINATION GAS/ELECTRIC MODELS continue — This water heater is designed to operate with gas, electricity, or a com- bination of both.

Provide adequate clearance at rear of unit for service of water connec- tions and operation of manually re-setable high temperature limit switch on combination gas/electric units.

1. Follow GENERAL INSTALLATION instructions. NOTE: All wiring must comply with applicable electrical codes.

  • CAUTION

PRODUCT DAMAGE

  • When using Romex® with a bare earth ground, take care to position ground wire so it does not contact the heating element terminals.

  • Use electrical metallic tubing, flexible metal conduit, metal clad cable, or nonmetallic-sheathed cable with grounding conductor. Wire must have a capacity of 1500 watts or greater. The wiring method must conform to applicable sections of article 551 of National Electrical Code ANSI/NFPA 70.

    • 2.

      Refer to Wiring Diagram. Make 120 VAC electrical connections from junction box on back of unit.

      • a.

        Connect hot lead to (1) Black.

    • b.

      Connect common lead to (2) White.

    • c.

      Connect ground wire from electrical service to (3) green ground lead in junction box 3. Place switch in “OFF” position.

  • When a cord and plug connection to the power supply are used on water heater, power cord must be UL listed as suitable for damp loca- tions, hard or extra hard usage. It must be a flexible cord such as type S, SO, ST, STO, SJ, SJT, SJTO, HS or HSO cord as described in National Electrical Code, ANSI/NFPA 70. The length of external cord to water heater, measured to face of attachment plug, shall be no less than 2 feet nor more than 6 feet. Supply cord must be a minimum of 14 AWG and attachment plug must be rated at 15 amps.

  • CAUTION

ELECTRICAL DAMAGE

  • Label all wires before disconnecting when servicing controls.

  • Verify proper operation after servicing.

ELECTRONIC IGNITION - WIRING INSTRUCTIONS 1. Install unit according to GENERAL INSTALLATION instructions. NOTE: It is recommended unit be connected directly to a 12V DC battery or to filtered side of an AC/DC converter. Avoid connections to unfiltered side of an AC/DC converter whenever possible. Use a minimum of 18 gauge wire, UL and CSA listed. Refer to WIRING DIAGRAM. Install remote switch in a convenient loca- tion. Position wall plate with letters up. Before making connections turn switch OFF. The switch is off when the button is depressed towards terminal see wiring diagram.

  • 2.

    Installing wires:

    • a.

      blue lead to switch terminal (6) on indicator light of switch

    • b.

      terminal (4) on indicator light of switch to negative battery terminal

    • c.

      green lead to negative battery terminal

    • d.

      brown lead on water heater to terminal (3) on switch

    • e.

      terminal 2 on switch to positive battery terminal.

  • 3.

    Read ELECTRONIC IGNITION OPERATION.

PILOT RELIGHT - WIRING INSTRUCTION

  • 1.

    Install unit according to GENERAL INSTALLATION instructions.

  • 2.

    Refer to Wiring Diagram. Use 18 gauge wire, UL/CSA listed.

  • 3.

    Read PILOT & PILOT RELIGHT OPERATIONS.

CONSUMER SAFETY WARNINGS

  • WARNING

EXPLOSION OR FIRE

  • DO NOT store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

  • Should overheating occur, or gas supply fail to shut off, turn OFF manual gas control valve to appliance, or turn gas OFF at the LP tank. On ELECTRONIC IGNITION MODEL turn operating switch to OFF position and remove red wire from left hand terminal of ECO switch or turn gas OFF at the LP tank.

  • Use with LP gas only.

  • Shut off gas appliances and pilot lights when refueling.

  • On PILOT RELIGHT MODELS, turn off the ignition module when refuel- ing gasoline tanks or LP tanks.

  • Turn gas OFF at the LP tank when vehicle is in motion. This disables all gas appliances and pilot lights. Gas appliances must never be operated while vehicle is in motion. Unpredictable wind currents may be created which could cause flame reversal in the burner tube, which could result in fire damage. The thermal cut off fuse could also be unnecessarily activated resulting in a complete shut- down of the water heater requiring replacement of the thermal cut off. See maintenance of electronic ignition water heaters for further explanation of the thermal cut off.

  • LP tanks must be filled by a qualified gas supplier only.

HOW TO OPERATE YOUR WATER HEATER

    • CAUTION FIRE

  • Do not smoke or have any flame near an open faucet.

If water heater has not been used for more than two weeks, hydrogen gas may form in water line. Under these conditions to reduce the risk of injury, open hot water faucet for several minutes at kitchen sink before you use any electrical appliance connected to hot water system.

If hydrogen gas is present, you will probably hear sounds like air escaping through the pipe as water begins to flow.

  • WARNING

SCALDING INJURY

  • Do not tamper with pilot orifice.

  • CAUTION

PRODUCT FAILURE

  • Do not operate without water in tank.

PILOT OPERATION

  • 1.

    Turn gas control valve knob (FIG 7-B or FIG 8-B) to OFF position.

  • 2.

    Wait at least five minutes to allow accumulated gas in burner com- partment to escape.

  • 3.

    Water heater may be equipped with a White Rodgers® or Robertshaw Unitrol® Control.
