When Installing this Product...
1.
Read these instructions carefully. Failure to follow them
can damage the product or cause a hazardous
condition.
2.
Check the ratings given in the instructions and on the
product to make sure that the product is suitable for
your application.
3.
Installer must be a trained, experienced service
technician.
4.
After installation is completed, check out product
operation as provided in these instructions.
WARNING
Electrical Shock Hazard.
Can cause serious personal injury or death.
Disconnect power supply before beginning installation.
More than one disconnection can be involved.
Mounting
NOTE: On flange models, remove the label holding the
O-ring in place and make sure O-ring seal is in place
before mounting the pressure switch on the valve.
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.

INSTALLATION
WARNING
Explosion or Fire Hazard.
Can cause severe personal injury, death or
property damage.
Observe all safety requirements each time a control is
installed on a burner.
M17124
C6097 models with flange mount can be fitted directly to
Honeywell Integrated Valve Train (model specific). See Fig. 2
and Table 1. The flange mount models vent internally, with no
external tap.
Mount the C6097A,B in any position.
Leak Check
After installation, perform a leak check on the pressure switch:
1.
Turn on main gas. Make sure gas has reached the
pressure switch (e.g., high gas pressure switch)
2.
Check installation for gas leaks using a gas leak
detector or a soap solution.

WIRING
WARNING
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.

SETTINGS AND ADJUSTMENTS
Pressure Setpoint Adjustment
To adjust the pressure setting, turn the setpoint adjustment
dial (Fig. 3, 4 and 5) clockwise to increase the
pressure setting and counterclockwise to decrease the

OPERATION AND CHECKOUT
Operation
The manual reset C6097A diaphragm actuates the snapacting 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.
The manual reset C6097B diaphragm actuates the snapacting 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.
Manual Resetting
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.
To reset, once normal operating pressure is restored, push the
reset button in as far as it goes, then release.
IMPORTANT
Lockout models cannot be made to recycle
automatically by permanently holding in the reset
lever.
Checkout
C6097 Gas Fuel Application
1.
Set cutoff pressure.
2.
Open main supply line. Depress reset lever on lockout
models until switch makes control circuit.
3.
Set controller and limit switch to call for heat.
4.
For C6097A: Close the manual gas shutoff valve.
C6097 should open control circuit when pressure
reaches cutoff point.
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.
5.
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).
6.
Allow system to operate through at least one complete
cycle to make sure all components are functioning
properly.
C6097A Air Application
1.
Set cutoff pressure.
2.
Turn on fan.
3.
Block fan inlet or filter area. Switch should break control
circuit when pressure drops to cutoff point. Manual reset
models lock out.
4.
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.
