BBSK INSTALLATION INSTRUCTIONS
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 |
| panel. See Figure 9. |
| *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 |
| 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. See Figure 10. |
STEP 5. | Secure P/N 40225 switch bracket to the BBSK control switch using two (2) #6x¼” screws provided. See Figure |
| 10. |
STEP 6. | Place BBSK control switch inside front panel, align engagement holes with clearance holes in P/N 40230 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 11. |
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 10. |
STEP11. | 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 11. 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 12. |
STEP 14. | Close the front panel door. |
STEP 15. | Follow the lighting instructions to place the heater in operation. |
