L.B. White I-40 Infraconic Spark Ignition - Manual (Page 11)

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.
There are two optional configuration zone control panels
available. These are high and medium capacity with
electrically operated solenoids for incorporation into building
environmental control systems.
The panel utilizes two normally closed solenoids. When
energized by the building controller, the first stage solenoid
will deliver 2 psig to the heater (approximately half the
heater output). As demand from the building environment
controller increases, the second stage solenoid opens,
delivering 5 psig to the heater for full heat output. Spark
ignition infraconic heaters must only be installed with a
solenoid controlled zone panel designed specifically for the
heater. Use of zone panels without solenoid control will
result in high carbon monoxide levels and poor combustion.

configuration for your specific application.
The zone control panel must have an adjustable high
pressure regulator installed upstream of the inlet of the
zone control panel. This regulator may be purchased from
the L. B. White Co. as an optional accessory. For L.P. gas,
the regulator must be capable of handling a maximum inlet
pressure of 10 psi, while supplying an outlet pressure of 5
psi nominal. This pressure is supplied to the zone control or
individual controlled heater. For natural gas, a regulator
must be installed to supply an outlet pressure of 5 psi
nominal.

FILTER SLEEVE
Although not required, the filter kit is recommended to
provide additional dust filtration capability and capacity for
Infraconic heaters when installed in severely dusty
environments.
1. Attach filter sleeve to injector body. The air housing
tabs fit into the slots on the sleeve. Rotate the sleeve
to lock it onto the air housing.
2. Position the filter onto the sleeve. Ensure all sleeve
holes are covered by the filter.
3. Securely attach the filter to the sleeve using the
beaded cable tie.
4. Ensure filter does not sag or touch heater’s canopy.
