The C6097 models allow NPT or flange (directly to valve)  
mounting. The NPT models have a hexagonal fitting with a  
1/4 in. NPT tapping, which is the high pressure connection, in  
differential applications. The bleed fitting is 1/8 in. NPT  
tapped. In differential pressure control applications using air  
only, connect the lower pressure to the bleed fitting. See Fig. 1  
and Table 1. In applications using combustible gases, vent the  
bleed tapping according to applicable standard code or  
jurisdictional authority.

Turn on main gas. Make sure gas has reached the  
pressure switch (e.g., high gas pressure switch)  
Check installation for gas leaks using a gas leak  
detector or a soap solution.

WARNING  
Explosion or Fire Hazard.  
Can cause severe personal injury, death or  
property damage.  
Observe all safety requirements each time a control is

Electrical Shock Hazard.  
Can cause serious personal injury or death.  
Disconnect power supply before beginning installation.  
More than one disconnection can be involved.  
Make sure that all wiring agrees with all applicable local  
codes, ordinances and regulations. An opening is provided to  
accommodate rigid conduit or armored cable for line voltage  
operation (see Fig. 3 and 4). Do not overload the switch  
contacts (see Switch Ratings in the Specifications section).  
The switching schematic is shown in Fig. 5.

OPERATION AND CHECKOUT  
Operation  
Checkout  
The manual reset C6097A diaphragm actuates the snap-  
acting switch to break a control circuit and lock out when  
pressure falls to the scale setting. The recycle C6097A  
models recycle automatically when the control circuit returns  
to scale setting plus differential.  
C6097 Gas Fuel Application  
1.  
2.  
Set cutoff pressure.  
Open main supply line. Depress reset lever on lockout  
models until switch makes control circuit.  
Set controller and limit switch to call for heat.  
For C6097A: Close the manual gas shutoff valve.  
C6097 should open control circuit when pressure  
reaches cutoff point.  
3.  
4.  
The manual reset C6097B diaphragm actuates the snap-  
acting switch that breaks a control circuit and locks out when  
the pressure rises to the scale setting. The recycle C6097B  
models recycle automatically when the control pressure falls  
to the scale setting minus differential.  
For C6097B: Open the manual gas shutoff valve, wait a  
few minutes for the pressure to rise; then lower the  
scale setting until the switch breaks control circuit and  
locks out.  
For C6097A: Open the shutoff valve, return the  
pressure switch to its original setting and press the reset  
button (if necessary).  
For C6097B: raise setting to normal and press reset  
button (if necessary).  
Allow system to operate through at least one complete  
cycle to make sure all components are functioning  
properly.  
Manual Resetting  
5.  
6.  
The C6097A manual reset models lock out when pressure  
falls to the scale setting and require manual resetting after the  
pressure rises to scale setting plus differential to resume  
normal operation.  
The C6097B manual reset models lock out when pressure  
rises to the scale setting and require manual resetting after  
the pressure falls to scale setting minus the differential to  
resume normal operation.  
C6097A Air Application  
To reset, once normal operating pressure is restored, push the  
reset button in as far as it goes, then release.  
1.  
2.  
3.  
Set cutoff pressure.  
Turn on fan.  
Block fan inlet or filter area. Switch should break control  
circuit when pressure drops to cutoff point. Manual reset  
models lock out.  
Remove obstruction. Press reset lever (manual reset  
models) and allow system to operate through at least  
one complete cycle to be sure all components are  
functioning properly.  
IMPORTANT  
Lockout models cannot be made to recycle  
automatically by permanently holding in the reset  
lever.
