Hearth and Home Technologies CNXT4842IH, CNXT4842ILT, CNXT4842ILH WSK-MLT Operating Instructions

I. WSK-MLT Operating Instructions

The ON/OFF rocker switch in the fireplace (located near the gas valve) must be in the “OFF” position for use with the WSK-MLT system. The ON/OFF rocker switch will NOT function with this device on Intellifire (IPI) mod- els except during a power outage. The ON/OFF rocker switch will only be used to control the fireplace in a no- power condition.

After all connections are made and the control box is grounded, plug power cord into the fireplace junction box. The wall switch will be functional at this time.

For IPI system, refer to “Operation Under Battery Power” for instructions.

Note: The temperature displayed by the wall switch may take up to 30 minutes to stablize on initial power-up.

Note: Check control box and assure switch is in the “OFF” position. This switch is only used on Intellifire (IPI) control systems under battery operation.

J. Setting Flame Height/Manifold Pressure

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

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

•Press flame button once (see Figure 12.8); fireplace will light with flames on high.

•Turn solenoid clockwise to increase pressure, counterclockwise to decrease pressure until manifold pressure on high is 3.5 in. water column for natural gas (NG), 10.0 in. water column for propane (LP).

•Once pressure is achieved sping jam nut on solenoid step tight against regulator face to prevent rotation. Do not overtighten.

•Press flame button twice to turn fireplace off.

•Remove manometer tube and tighten or close pressure tap. Use a commercially available, non-corrosive leak check solution to carefully check the pressure tap for leaks. Be sure to rinse off all leak check solution following testing.
