Zone Control Panel Function And Installation; Installing Dust Filter - L.B. White 140 Owner's Manual And Instructions

ZONE CONTROL PANEL
COMPONENT FUNCTION AND INSTALLATION
The zone control panel is a remote mounted control system
allowing the operation of a specific amount of heaters within
a certain zone of the building.
These panels will control the following quantity of heaters
depending on fuel type.

The zone control panel must be mounted to a flat, stable
wall inside the building. Use lag screws provided. For the
modulating zone panels, care must be taken to ensure that
the thermostatic control module is not exposed to outside
air temperatures. Exposure of the thermostatic control
module to outside air temperatures (Example: when
sidewall curtains are open) may cause the heater to provide
unwanted heat.

INSTALLING DUST FILTER

IMPORTANT
This filter kit is designed to provide additional dust filtration
capability and capacity for Infraconic heaters when
installed in severely dusty environments.
1. Attach filter adapter to injector body. The injector
body tabs fit into the slots on the adapter. Rotate the
adapter to lock it onto the injector body.
