2.0 Operating Instructions
For units WITH factory installed rocker switch.
The ON/OFF rocker switch on the fi replace (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 Intellifi re (IPI) models except
during a power outage.
For units WITHOUT factory installed rocker switch.
The ON/OFF rocker switch now installed on the fi replace
must be in the OFF position for use with the IPI or stand-
ing pilot system. The ON/OFF rocker switch will only be
used to control the fi replace in a no-power condition. For
standing pilot systems use the rocker switch to turn the
fi replace on and off. When power is restored switch the
rocker switch to OFF. For IPI system refer to “Operation
Under Battery Power” for instructions.
After all connections are made and the control box is
grounded, plug power cord into the fi replace junction box.
The wall switch will be functional at this time.

2.1 Setting Flame Height/manifold pressure
(To be done by a qualifi ed service technician). Upon initial
power-up of this device, valve pressure must be set for
fl ame adjustment.
• Loosen output pressure tap on valve and connect with
pressure manometer.
• Press fl ame button once (Fig. 7); fi replace will light with
fl ames on high.
• Turn solenoid clockwise to increase pressure, counter-
clockwise to decrease pressure until manifold pressure
on high is 3.5” water column for natural gas (NG), 10.0”
water column for propane (LP).
• Once pressure is achieved spin jam-nut on solenoid stem
tight against regulator face to prevent rotation. Do not
overtighten.
• Press fl ame button twice to turn fi replace off.
• Remove manometer tube and tighten or close pressure
tap. Use a soap solution to carefully check the pressure
tap for leaks.
NOTE: The temperature displayed by the wall switch may
take up to 30 minutes to stabilize on initial power-up.
NOTE: Check control box and assure switch is in the “OFF”
position. This switch is only used on Intellifi re (IPI) control
systems under battery operation.
