Hearth and Home Technologies WSK300 operating instructions Installing the Control Box

Installing the Control Box

CAUTION

•Do not install the control box when fireplace is hot.

•Do not plug control box in until all connections are complete.

1.Place control box into the base pan area of the fire- place. Place unit as close to the louvers or decorative front as possible and to either the left or right side.

2.Connect the red, yellow or white, and green wires to the appropriate labeled terminals on the control box.

WARNING

Shock hazard

•Failure to cap unused auxiliary connectors can result in electric shock.

3.If fireplace is equipped with a fan, plug the fan cord into “A1” on the control box. Terminals that are not occupied should be capped with the insulator caps provided. Failure to cap unused auxiliary connectors can result in a possible electric shock.

4.Disconnect the multiwire connector from existing green control box. Connect the end just disconnected to the matching terminal on the new black control.

5.Connect the new lead wire set to black and green con- trol boxes matching connectors.

6.Attach the provided ground clip (see Figure 2) to the nearest available sheetmetal edge. Attach the black leads with the 1/4 inch female connector to the ground clip.

Note: Failure to ground the new 6 to 8 pin wiring harness may cause the wall control to lock up.

7.All wiring should be complete. See Figure 2 to confirm that all connections are correct.

8.After confirming wiring is correct, plug in control box to junction box.

Note: Proper settings and operation MUST be confirmed before installation is complete.

Setting Flame Height / Manifold Pressure

WARNING

Explosion risk

•Incorrect adjustment of solenoid may cause delayed ignition.

Fire risk

• Incorrect adjustment of solenoid may cause a fire.

Note: A manometer MUST be used to set the manifold pressure on the gas valve.

(To be done by a qualified service technician). Upon initial power-up of this device, valve pressure must be set for flame adjustment.

1.Loosen output pressure tap on valve and connect with pressure manometer.

2.Press mode button to “ON”; fireplace will light with flames on high.

3.Turn solenoid clockwise to increase pressure, coun- terclockwise to decrease pressure until manifold pres- sure on high is 3.5 inch water column for natural gas (NG), 10.0 inch water column for propane (LP).

4.Once pressure is achieved spin jam-nut on solenoid stem tight against regulator face to prevent rotation. While holding solenoid, tighten jam nut with 1/2” wrench. This will ensure that the solenoid remains locked in the proper position.

5.Press mode button to turn fireplace off.

6.Remove manometer tube and tighten or close pres- sure tap. Use a commercially available, non-corrosive leak check solution to carefully check the pressure tap for leaks.
