Wsk-Mlt Operating Instructions; Setting Flame Height/Manifold Pressure - Heatilator CNXT4236IT Owner's Manual

I. WSK-MLT Operating Instructions
The ON/OFF rocker switch in 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 func-
tion with this device on Intellifi re (IPI) models except during a
power outage. The ON/OFF rocker switch will only be used
to control the fi replace in a no-power condition.
After all connections are made and the control box is ground-
ed, plug power cord into the fi replace 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 Intellifi re (IPI) control
systems under battery operation.

J. Setting Flame Height/Manifold Pressure
(To be done by a qualifi ed service technician.) Upon ini-
tial 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 (see Figure 10.8); fi replace will
light with fl ames 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 fl ame button twice to turn fi replace 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.
