INSTALLATION

M

OUNTING CONTROL BOX

The control box must be mounted within 6’ of the vent damper, and within
reach of the appliance’s existing damper cable. If the control box must be
mounted out of reach of the power venter’s attached wiring, an additional
installer supplied junction box and wiring (with approves wiring enclosure if
necessary) will be required. (See Figure 1 & 2)

1. Install the flexible conduit connector onto the CK-92* control box and
secure with fastening nut. If additional wiring is required, install the
flexible conduit connector onto the installer supplied junction box.

2. Fasten the flexible conduit from the SWG Venter into the conduit
connector. Mount the CK-92* control box onto a non-heated vertical
surface of the appliance or nearby wall or floor joist through the four
dimpled locations on the base of the box. NOTE: The mounted

pressure switch diaphragm must be mounted with a vertical orientation;
see label on pressure switch. (See Figure 3) If required, run additional

wiring as in figure 2 and connect to CK-92* control box, if required, using
the supplied flexible conduit connector and approved connectors and
anti-short bushings.

RESSURE SWITCH SENSING TUBE INSTALLATION

1. Attach the 1/4 inch tubing connector to the pressure tube on the SWG
Venter. (See Fig. 3)

2. Connect installer supplied 1/4" O.D. aluminum, copper or stainless steel
tubing to the tubing connector.

3. Route the tubing to the CK control box and connect the tubing to the
pressure switch using supplied plastic nut. When routing the tubing,

avoid kinking the tubing by bending the tubing too sharply. Support the
tubing at 2’ intervals using installer supplied tube clamps.

ADJUSTMENTS

ROVING SWITCH ADJUSTMENTS

P

After proper air flow is established, the pressure switch adjustment is made by
turning the pressure switch adjustment screw clockwise (See Figure 4) until
burner operation stops. Turn the adjustment screw counterclockwise until
burner ignites. Turn the adjustment screw an additional 1/4 to 3/4 turn
counterclockwise to ensure adequate switch adjustment.

WARNING: Failure to properly adjust the pressure switch as specified above
could lead to improper operation of the pressure switch which will result in a
hazardous condition and bodily harm!

T

HERMOSTAT HEAT ANTICIPATOR ADJUSTMENT

After venting kit installation and checkout, check the amperage current draw through the
thermostat circuit and adjust the thermostat anticipator accordingly.

INSTALLATION OF GAS PRESSURE SWITCH
CAUTION: Check gas control valve pressure. Pressure MUST NOT exceed 14" WC

pressure.

1. Remove pressure tap plug in gas valve. (See Figure 5) NOTE: If installing on an
existing appliance, shut off gas supply to gas valve before plug removal.

2. Replace the pressure tap plug with the 1/8" pipe nipple and pipe tee. Install pressure
tap plug at the bottom of the pipe tee. (See Figure 6)

3. Install the gas pressure switch into the side of the pipe tee. The gas pressure switch
is supplied with a restrictor orifice in the inlet and outlet ports. With these orifices in
place, the switch does not need to be vented. This feature complies with current
ANSI standards for gas regulators. (See Figure 7).

CAUTION: If for any reason the system has shut down during operation, the cause of
the system failure should be investigated and corrected before resetting the safety
switch and restarting the system.

DRAFT HOOD SAFETY SWITCH INSTALLATION PROCEDURE
NOTE: 12 ga. wire should be used when wiring safety spillage switches, to reduce the

voltage drop in the thermocouple circuit.

1. Remove the thermocouple from the gas control valve. (See Figure 5)

2. Thread the junction block into the thermocouple port and thermocouple into the
bottom of the junction block. (See Figure 8)
