ELECTRICAL CONNECTIONS

The water heater must be connected to a properly grounded electrical branch circuit. A dedicated circuit is preferred. Do not use a GFI outlet.

Refer to the rating plate attached to the water heater to determine the electrical requirements for the heater. Ensure the circuit provided is correct for these requirements.

Important: Do not use an extension cord to connect the water heater to an electrical outlet.

Important: The electrical controls used inside the gas control of this water heater are polarity sensitive. Ensure the electrical supply is connected correctly in the receptacle box. Failure to connect correctly will prevent the unit from functioning properly.

When all the water, gas and venting connections have been correctly made, fill the tank as directed in the section

“FILLING THE WATER HEATER”.

When the tank has been filled, connect the electrical power and proceed with starting the water heater as directed in the “CALIBRATION” section.

CALIBRATION

The water heater must be calibrated as follows before being put into service. The Calibration Procedure examines and measures certain details of your installation and automatically sets some control parameters. Before starting the Calibration Procedure, the heater must be properly installed and connected to the water piping and the vent system. Ensure all panels, covers and doors are in place.

Important: To avoid a possible “end of call-for-heat” (and consequent interruption of the Calibration Procedure), a continuous water draw from the heater is recommended during the calibration.

This procedure assumes that the heater is installed with DIP switch 4 in the calibration (ON or “down”) position (see Figure 33a).

To calibrate the heater:

1.Plug the power cord into a 120Vac/60Hz outlet.

2.Press the Standby Button to turn on the heater and initiate the Calibration Procedure.

3.The Calibration Procedure will last about 6 minutes. Do not interrupt this procedure once it has started. After a successful calibration the heater will go into standby mode. During the calibration if the “call-for-heat” ends, the calibration was not completed and the E36 error message will be shown on the display. If this occurs, unplug the power cord and repeat steps 1 and 2.

To put the heater into service after a successful calibration:

1.Unplug the power cord from the 120Vac/60Hz outlet

2.Open (plastic) front door of the heater and remove the service cap of the heat engine. The DIP switches are located on the PCB which is mounted on the right-hand side of the heat engine.

3.Set DIP switch 4 in the normal (OFF or “up”) position (see Figure 33a).

4.Reinstall the front cover of the heat engine, close and latch the front door of the heater.

5.Plug the power cord into the 120Vac/60Hz outlet.

6.Press the Standby Button to turn on the heater and start the unit.

FIGURE 33a

The E36 “calibration error” occurs in the following situations:

Calibration switch (DIP switch 4) is in the calibrate (ON or “down”) position and an “end call-for-heat” occurs before the Calibration Procedure is finished.

Calibration switch (DIP switch 4) is in the calibrate (ON or “down”) position there is no “call-for-heat” within 6 minutes of turning on the power.

Calibration switch (DIP switch 4) is in the calibrate (ON or “down”) position and the unit is calibrated but the DIP switch is not set to the normal (OFF or “up”) within 6 minutes after the Calibration Procedure is finished.

Calibration switch (DIP switch 4) is in the normal (OFF or “up”) position and the unit is not calibrated and 1 minute (or more) passes after turning on the power.

If an E36 error message is displayed:

1.Unplug the power cord from 120Vac/60Hz outlet.

2.Open front door of the heater and remove the front cover of the heat engine.

3.Check that (or set) DIP switch 4 is in the calibrate (ON or “down”) position.

4.Generate a 5 minute (minimum) water draw from the heater.

5.Repeat the calibration procedure.

NOTE: If changes are made to the vent system or the heater is re-located, the Calibration Procedure must be repeated.
