COZY W255G Installation And Operating Instructions Manual page 13

STEP 1.
Select left or right side of front panel for most convenient location of the temperature control knob.
Remember to choose the side that allows adequate clearance for accessibility to adjust the control knob.
STEP 2.
On selected side, locate three (3) vertical dimples beginning approximately 20-½" above bottom of the front
panel. See Figure M-1 (on page 14).
*On Gravity Wall Furnaces manufactured prior to November 2005 (without bracket hole
dimples in the left and right side), you may use the gravity BBSK bracket as a template
to locate holes. Measure 20-1/2" up on the preferred side, to locate lowest hole.
STEP 3.
Using these three (3) dimples as locator, drill three ¼" holes.
STEP 4.
Remove the BBSK control switch from the packing set. Remove the control switch mounting bracket from the
control switch by removing the two M4 screws holding it to the switch. See Figure M-2 (on page 14).
STEP 5.
Secure P/N 1016901 switch bracket to the BBSK control switch using the two M4 screws removed previously.
See Figure M-2 (on page 14).
STEP 6. NOTE: Bend louvers on front panel as necessary to allow sufficient
clearance for BBSK control switch and wire terminals.
Place BBSK control switch inside front panel, align engagement holes with clearance holes in P/N 1016900
heat shield and the ¼" drilled holes in the front panel. Attach using two (2) #8x½" screws provided. Make sure
heat shield is between the BBSK control switch and the heat exchanger.
STEP 7.
Connect each end of the black wires to the two outside terminals on the BBSK control switch, route wires
down the inside of the front panel. See Figure M-3 (on page 14).
STEP 8.
Straighten the bulb capillary tube using extreme care not to bend or damage the tube, route the tube down
the inside of the front panel.
STEP 9.
Install the front panel onto the wall furnace.
STEP 10. Insert the control knob onto the control rod. See Figure M-2 (on page 14).
STEP 11.
Open the front panel door.
STEP 12. Connect one black wire to the stripped end of the blue blocked flue switch wire. Connect the other black wire
to the "TH/TP" terminal on the gas valve. See Figure M-3 (on page 14).
NOTE: If you are replacing an existing wall thermostat, you must first disconnect
the thermostat wires from the gas valve.
STEP 13. Secure the sensing bulb to the bottom of the gas valve using the nylon clamp and blunt screw provided.
See Figure M-4 (on page 14).
STEP 14. Close the front panel door.
STEP 15. Follow the lighting instructions to place the heater in operation.
