Ignition Conversion Kit Instructions

Applies: All UEAS Models Built Prior to March, 2013

Prior to March, 2013 all UEAS models were built at the factory with a separate Time Delay Relay (reference P/N 221388) and utilized DSI Control

Module circuit board P/N 195265.

All UEAS models built at the factory after March, 2013 do not use a separate Time

Delay Relay and utilizes a different DSI Control Module circuit board (reference P/N

269867). This circuit board has the time delay “built in” so as to eliminate the need for a separate time delay relay.

This set of instructions provide the steps required to convert models built prior to

March, 2013 to current ignition control specifications.

WARNING

This ignition conversion kit is to be installed by a qualified agency in accordance with these instructions and in compliance with all codes and requirements of authorities having jurisdiction.

Failure to follow instructions could result in death, series injury and or property damage. The qualified agency performing this work assumes responsibility for this installation.

1. Turn off the gas supply at the shutoff valve upstream of the combination valve and turn off the electrical supply powering the unit.

2. Locate “Right Side” of unit and remove the two retaining screws as shown in the sketch below.

Note: Model 260 or 310 shown above.

(Models 130 & 180 have a single access cover)

The “Low Side Cover” can now be tilted out at the bottom and removed to access ignition system components.

3. Now the ignition system components can be seen, as shown in the sketch below.

4. Looking at the DSI Control Module (circuit board), notice the that the

Time Delay Relay is a separate component located in the upper right side next to the circuit board as shown in the sketch below.

5. Notice that the time delay relay has two electrical terminals with a blue wire attached to each therminal as shown below.

Doc No D303109 (2-16), page 2

6. Remove and discard the one center hold down screw that retains the relay to the unit.

Now remove the time delay relay and set it (with its two blue wires still attached to the time delay relay electrical terminals) in front of the circuit board as shown in the photo on the right.

Next remove and discard the one blue wire that is attached to the time delay relay electrical terminal (see arrow) and the other end of this same wire that is attached to the gas valve terminal (see arrow).

7. Remove the remaining blue wire that is attached to the other electrical terminal on the time delay relay as indicated with arrow in picture shown below on the left and connect it to the gas valve electrical terminal (reference arrow) as shown below in the picture on the right.

8. Remove all wires & plugs attached to the DSI Control Module (circuit board). Then “squeeze” the tops of the four white bayonet style posts

(shown in ellipses) to release the circuit board. Now remove and discard the board. Reference photo shown below.

9. Install the new DSI Control Module (circuit board) P/N 269867 that was included in this kit onto the four white bayonet style posts.

10. Change the wiring diagram label on the heater. Place the label that was included in this kit, P/N 221211 over top of the existing one. It is a shelf adhesive label.

11. Using the wiring diagram shown on page 4, reconnect all plugs and wire connections. ( Note, the old wiring diagram is shown on page 5.

Use it for reference ONLY!)

12. Turn on the electric and gas. Relight the unit following the instructions on the lighting instruction plate.

13. Power up unit and using the units Installation manual, verify proper operation.

OPERATING SEQUENCE

1. SET THERMOSTAT AT LOWEST SETTING;

FAN SWITCH AT "AUTO" POSITION.

2. TURN ON MANUAL GAS VALVE.

3. TURN ON POWER TO UNIT.

4. SET THERMOSTAT AT DESIRED SETTING.

5. THERMOSTAT CALLS FOR HEAT, ENERGIZING THE VENTER MOTOR.

6. VENTER PRESSURE SWITCH CLOSES, FIRING UNIT AT FULL RATE.

7. BURNER FLAME IS SENSED, AND IN 30 SECONDS THE BLOWER

MOTOR IS ENERGIZED.

8. IF THE FLAME IS EXTINGUISHED DURING MAIN BURNER OPERATION,

THE INTEGRATED CONTROL SYSTEM CLOSES THE MAIN VALVE AND

MUST BE RESET BY INTERRUPTING POWER TO THE CONTROL CIRCUIT

(SEE LIGHTING INSTRUCTIONS).

9. SET FAN SWITCH AT "ON" POSITION FOR CONTINUOUS BLOWER OPERATION.
