Theory of Operation:
A natural gas burning appliance requires roughly 10 cubic feet of air to properly combust a single cubic foot of
gas. Minute airborne particles entrained during this process pass through the combustion system and are
incinerated. However, some particles may be trapped within the combustion system, building up over time,
causing an eventual decrease in the operational efficiency of your appliance. he rate at which this build up
may occur varies from kitchen to kitchen and is greatly influenced by the environment (breading, flour etc.) and
kitchen processes (i.e. cleaning). Historically, frequent cleaning of burners and other combustion related
components has been the only way to insure optimal efficiency of your fryer. he Pitco Self Cleaning Burner
System (SCBS) will minimize the cost and inconvenient down time of frequent cleaning of combustion system
components. Each morning when the appliance is turned on, a small amount of gas is momentarily diverted
into a runner tube, which, after passing by the pilot, ignites and causes a short but effective light back at the
main burner orifice. his brief flame bath cleans the inside of the burner face by incinerating any foreign matter
that has accumulated from the previous day’s operation.
he Pitco Self Cleaning Burner System is designed to help maintain proper operation and efficiency of your
appliance’s combustion system by minimizing the build up of any foreign material inside the burner housings.
Proper installation of this upgrade and periodic maintenance of the appliance are critical to safe, reliable and
efficient operation.

Follow this procedure for Installation of Self Cleaning
burners and SCBS arm:
a. Disconnect the control harness from the main gas
valve and tuck it out the way to avoid damaging the
harness during this procedure.
b. If your appliance has a solid-state control (or
auxiliary thermostat) behind the door, remove it at
this time. With a 5/16” nut driver remove the two
self-threading screws that mount the control to the
appliance, disconnect the control harness and tuck
it out of the way to avoid damaging the harness
during this procedure. Be sure to store the control
in a safe place to avoid accidental damage to it.
c. Using a 7/16” wrench, remove the pilot tubing from
the gas valve by turning the brass fitting counter-
clockwise. here is no need to remove the pilot
from the burner assembly.
WARNING
Ensure that the tank contents have been
drained before executing this step!

e. Using a 1 1/16” wrench and a 7/8” wrench, loosen
the brass fitting on the top of the gas valve and
disconnect the gas valve from the manifold inlet.
his will allow you to drop the gas valve down
and keep it out of the way during burner
replacement.
f. Using a 5/16” wrench, nut driver or screw gun bit,
remove all burners by removing the (2 ea.) self
threading screws holding them into the burner rack.
Retain these for reinstallation of the new burners.
Note: On models MG2 and SGH50, it will be
necessary to remove the air collars surrounding the
burner head.
WARNING
Be sure to keep the removed burners separate from
burners supplied with the upgrade kit The existing
burners WILL NOT work with the Pitco Self-Cleaning
Burner System DO NOT attempt to use the old burners
with the Pitco Self-Cleaning Burner System: an unsafe
condition may occur
g. Replace the burners to the LEF of the pilot with
burners supplied with the Pitco Self-Cleaning
Burner System upgrade kit, securing them with the
fasteners removed and retained in step f.
NOTE: Pre-tap the holes on mounting bracket on
the SCBS runner arm with the two self tapping

i. Capture the remaining burners on the SCBS Arm in
the same manner as in step h, and secure them into
the appliance, taking care not to strip the pre-threaded
holes.
j. Secure the SCBS Arm to left side of the burner to the
right of the pilot using two 10 X 24 self-threading
screws provided with the Pitco Self-Cleaning Burner
System Upgrade Kit.
he SCBS Arm should now be mounted properly and securely.
Inspect your work to insure that the burners are installed correctly.
Improperly mounted or poorly aligned burners may result in an
unsafe condition or poor appliance performance. hey should be
mounted properly on the orifice fittings, facing straight into the
burner tubes and secured tightly to the appliance.
Follow this procedure for installation of the SCBS Valve:
NO E: he valve type you receive in your kit may differ in appearance slightly from the one shown in these
instructions.
a. Re-attach the gas valve to the manifold inlet using a 1
1/16” wrench and a 15/16” wrench and, with a 3/16” (5
mm) hex key, remove the plug from the pressure tap
port on the OP portion (Outlet Side) of the valve,
next to the pilot fitting.

NO E: CE approved models will have a pressure test
fitting in this location. For CE approved models, remove
this pressure test fitting using a 7/16” (12 mm) wrench.
Using a 3/16” (5 mm) hex key, remove the plug from the
auxiliary pressure tap on the manifold inlet and replace
it with pressure tap fitting that you removed from the
OP (Outlet side) of the valve. Use teflon tape or apply
pipe joint compound on the threads of the fitting to
ensure a gas-tight seal.
b. Remove the straight 1/8” NP X ¼” compression fitting
from the U tube end of the SCBS Valve Assembly
provided with the kit and, with a 7/16” wrench, install it
into the recently vacated pressure test port on the OP
(Outlet Side) of the valve. Use teflon tape or apply pipe
joint compound on the threads of the fitting to ensure a
gas-tight seal.
NO E: he threads on this fitting (1/8’ NP and ¼”
compression) are not interchangeable. Be sure to
install the NP side of this fitting into the gas valve.
Failure to complete this step correctly could damage
the threads of both the fitting and the pressure test
port, and may result in gas leakage at this joint.
c. Remove the 1/8” NP X 90° ¼” compression fitting from
the other end of the SCBS Valve Assembly provided
with the kit and install the orifice tip, also provided in the
kit, on to the NP end of the fitting. Insert the orifice end
of this assembly into the runner tube installed previously
in this procedure. NOTE: Check the orifice against the
parts list included in these instructions to insure that it is
the correct size for the gas type of your appliance.
d. Mount the SCBS Valve Assembly into the appliance by
loosely attaching the U tube end of the assembly onto
the straight fitting that you installed into the OP (Outlet
Side) of the gas valve in step b.

e. hread the compression nut on the corrugated tubing
end of the SCBS Valve Assembly onto the orifice
assembly that you inserted into the runner tube in
step c and tighten with a 1/2” (13 mm) wrench.
f. Install the orifice retainer bracket onto the pilot
bracket and SCBS Orifice assembly. his will secure
the orifice assembly into the runner tube.
g. ighten ALL joints on the SCBS Valve assembly with
a ½” (13 mm) wrench. Reinstall the pilot tubing into
the gas valve.
h. Reconnect the control harness to the main gas valve,
and if you removed a Solid State Control earlier in
this procedure you may re-install it at this time.
Follow this procedure to prepare and install the
SCBS Control Board and Harnesses:
a. Using a phillips head screwdriver, remove the two
screws that secure front panel and rotate the control
assembly down. Disconnect the control harness and
remove the front panel assembly from the appliance.

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. he 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

e. If the appliance you are upgrading does NO have a
Solid State Control, proceed to step f in this section.
If the appliance that you are upgrading has a Solid
State Control, feed the other ends of the SCBS
Harness through the unused portion of the strain
relief holding the Solid State Control Harness and
proceed directly to step h in this section.
NOTE: If needed, you can carefully nudge open the
area in the strain relief with a screwdriver to make
additional room to insert the SCBS harness. ake
care not damage the harness during this procedure.
f. Using a 5/16 nut driver, remove the two screws on
the underside of the front panel that hold the slotted
bottom on. Remove the slotted front panel bottom;
this will allow easier access to the cable retainer
plate. Remove the two screws holding the cable
retainer plate onto the appliance and remove the
cable retainer plate, leaving the control cable held in
place by the square strain relief. Replace the cable
retainer plate that you removed with the new one
provided in the kit. Cable retainer plate style varies
from model to model; the one that came with your kit
should look exactly like the one that you removed
with an added hole.
g. Feed the SCBS harness through the hole in the cable
retainer plate. Collect and capture all wires in this
harness into the split grommet provided with the kit
and install the grommet into hole in the cable retainer
plate. he installation of the grommet is critical as it
insures that the wires will not chafe and/or short out
against the metal edge of the hole in the cable
retainer bracket.
h. You may now reconnect the main control harness to
the SCBS board exactly as it was connected to the
previous board, re-attach the front panel bottom and
reconnect, remount and close up the front panel
assembly.
