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 1.
*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 2.
STEP 5.
Secure P/N 1016901 switch bracket to the BBSK control switch using the two M4
screws removed previously. See Figure 2.
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 3.
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 2.
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 3.
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 4.
STEP 14. Close the front panel door.
STEP 15. Follow the lighting instructions to place the heater in operation.
