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.
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.
Both the flange mount and NPT mount models are supplied
with an Integral Vent Limiter. External vent line is not required.
If necessary, this 1/8-in. atmospheric vent fitting can be used
for the vent line connection.
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.
OPTIONAL SWITCH POSITION

Observe all safety requirements each time a control is
installed on a burner.
WARNING
Electrical Shock Hazard.
Can cause serious personal injury or death.

Installing the Position Indication Lamp Kit
(See Fig. 4)
1. Remove the cover from the C6097 by removing the
screws in the upper left and lower right quadrants of the
cover.
2. Place the lamp in the slot to the right of the dial, in the
upper right-hand corner of the C6097, with the base
down. Run the two lamp wires through the slit in the
upper left corner of the lamp slot.
3. Place the nut in the hexagonal depression in the lower
left-hand corner of the C6097.
4. Place the terminal plate over the nut and fasten the
terminal plate to the C6097 with the screw through the
bottom hole in the terminal plate.
5. Place the captive screw through the terminal lug on the
shorter wire and fasten the wire to the terminal plate with
the captive screw secured by the nut under the terminal
plate.
6. Using Fig. 5 or 6 for reference, fasten the terminal lug on
the longer lamp wire to either the normally open (NO) or
normally closed (NC) terminal of the C6097. Fig. 4. Installing the Position Indicator Lamp Kit.

Position Indicator Lamp Operation
The Position Indicator Lamp will light when the C6097
Pressure Switch opens and provides power to the lamp (see
Fig. 5or 6). An option alarm circuit can also be connected as
shown in the same figures.
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 pressure setting.

OPERATION AND CHECKOUT
Operation
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.
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.
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.

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.
