b. Disconnect the wiring harness from the relay board
mounted behind the front panel and remove the
relay board and insulation paper. Be sure to retain
the screws. The existing relay board may or may
not have a jumper plug as shown. If it does, remove
it from the old relay board and install it into the
same position on the “new” SCBS relay board
provided.
c. Install the insulation paper provided with the Pitco
Self-Cleaning Burner System Upgrade Kit onto the
backside of the SCBS Control Board and mount the
board in the front panel enclosure, using the same
screws and holes as the old board. Older revision
boards will have wires attached to the board for
the thermal cutout and a two pin connector for
the valve harness; these wires are not present
on newer revision boards, which have the
thermal cutout harness and valve harness
combined into one single harness.
NOTE
It is critical for proper operation that the
insulation paper is installed. Failure to install
the insulation paper may cause soldered joints
on the back of the Control board to short out
and damage the Control board and/or appliance.
d. Plug four-pin connector on SCBS Harness into
SCBS Relay Board and ground as shown, using the
existing fastener to secure ground cable to the
appliance chassis. Older revision models will
have the thermal cutout leads feeding directly
from the board, a two-pin connector for the
valve harness and a separate harness for the
thermal limit assembly. For older revision
boards, plug the two pin connector on the SCBS
Valve harness into the SCBS Relay Board and
ground as shown, using the existing fastener to
secure ground cable to the appliance chassis.
Connect the SCBS Thermal Limit Harness
(supplied with older revision kits only) to the red
and grey leads on the older revision SCBS Relay
Board.
