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. The 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. The 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. This brief flame bath cleans the inside of the burner face by incinerating any foreign matter
that has accumulated from the previous day’s operation.

The 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.

1/2“ (13 mm) wrench Small flat blade screwdriver
11/16” (18 mm) wrench (or socket) 3/16” (5 mm) hex key
7/8” (23 mm) wrench

Before you begin:

Verify that you have all the parts for the model that you are upgrading by checking the kit number and contents
against the exploded view drawings in the back of these instructions.

WARNING

The power supply to the appliance MUST be disconnected before performing this procedure.

WARNING

Ensure that the gas supply to this appliance is turned OFF before performing this procedure.

WARNING

Drain the tank and ensure that appliance has cooled to room temperature

before performing this upgrade. DO NOT work on a hot appliance or an

appliance containing hot cooking medium; serious personal injury may occur.

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. There is no need to remove the pilot

from the burner assembly.

WARNING

Ensure that the tank contents have been

drained before executing this step!

d. Using an 11/16” wrench or socket, loosen and

remove the drain valve nut and washer, and
remove the blue drain valve handle. Note: You may
want to place the nut and washer back on the valve
stem for safekeeping.

L80-029 Rev 5 10/07 2

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.

This 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 LEFT 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

screws provided in the kit before you install it.

h. With the ports FACING INWARD, insert the SCBS

Arm into the space between the burner venturis
and orifice holders of the newly installed burners.

3 L80-029 Rev 5 10/07

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.

The 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. They 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:

NOTE: The 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 TOP portion (Outlet Side) of the valve,
next to the pilot fitting.

L80-029 Rev 5 10/07 4

NOTE: 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
TOP (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” NPT 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 TOP
(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.
NOTE: The threads on this fitting (1/8’ NPT and ¼”
compression) are not interchangeable. Be sure to
install the NPT 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” NPT 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 NPT 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 TOP (Outlet
Side) of the gas valve in step b.

5 L80-029 Rev 5 10/07

e. Thread 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. This will secure
the orifice assembly into the runner tube.

g. Tighten 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.
(This will not be necessary if your model uses a solid­state control). Store the front panel assembly in a safe
place to avoid damaging the control.
