INDICATOR
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 pressure setting.

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.
