COMMON REPAIR PROCEDURES
PILOT/IGNITER REPLACEMENT – RADIANT BURNER
If replacing an Igniter on a Radiant Burner, we recommend removing the Burner� (See Removal and Cleaning of Radiant Burner
section�) While the Igniter can be replaced without Burner removal, most often the cause for the Igniter failure is debris in the Burner�
Be aware of the Pilot orifice located between the brass Compression fitting and the Igniter� The Igniter is attached to the Burner can
with a right angle bracket� Remove the screw holding the bracket to the Burner box, and remove the Igniter� Remove the bracket from
the old Igniter� Attach the bracket to the new Igniter and reinstall�
Whenever you are removing or replacing the Radiant Burner
Igniter, you should also replace the Igniter Gasket.
GAS VALVE REPLACEMENT
To remove the SV-2 valve on “trombone” style manifolds:
Loosen and separate the union located forward of the valve� Rotate the
valve in towards the center of the oven� It may be necessary to loosen some of the unistrut clamps, then remove the piping connected
to the valve, then the valve itself�
Newer manifolds:
Loosen the unistrut pipe clamps to access the valve for removal� To replace the SV-1 valve, a 1/2" Allen wrench
is necessary for removing the union from the valve� After installing the new valve, always check the Burner gas pressure and make
the proper adjustments as necessary� The specified manifold pressures for the SV-1 (IR) and SV-2 (Radiant) can be found on the
equipment nameplate beneath the oven�
THERMOCOUPLE REPLACEMENT
1.
Disconnect the Thermocouple wires at the Junction Box located on the Transformer Plate below the oven� These will be the red and
yellow wires that have the brown sleeve�
Note:
Wood-fired only: The tc wires are connected directly to the temperature readout at
the front of the oven�
2.
Cut the wire OFF at the base of the bad Thermocouple�
3.
Mark the Thermocouple where it enters the fitting—use this mark as a reference for the depth of the new Thermocouple�
4.
Loosen the retaining nut that secures the Thermocouple to the bottom of the oven�
5.
Slide the Thermocouple out and remove the old fitting from the oven floor�
6.
Using the Compression fitting supplied with the new Thermocouple, slide the new unit in as far as it will go, then check your
reference mark� Hold the Thermocouple in so it is bottomed out in the hole while tightening the Compression fitting�
7.
Retighten the nut to compress the fitting on to the Thermocouple�
Make certain the Thermocouple is properly located before
tightening the nut, as it will be impossible to relocate once the nut is tightened.
NOTE:
On RFG-IR models, the end of the Thermocouple will need to be bent slightly at the tip toward the Infrared Burner to fit into
the floor casting�
8.
Attach the wire end of the new Thermocouple to the cut wire of the old Thermocouple and pull the new wiring into the conduit as
the old wire is pulled out at the J-box (or readout box) end�
ICS MODULE REPLACEMENT
1.
To remove either ICS Module, first turn OFF power to the oven�
2.
Remove the defective Module from its mounting plate�
3.
Install the new Module onto the mounting plate�
4.
One by one remove the wires from the old Module and connect them to the corresponding terminals on the new Module�
5.
Check wire connections�
6.
Restart the oven and verify proper operation�
7.
New style Fenwall Modules are provided with a new wiring harness� Connect these wires to the existing wiring as indicated
in the instructions provided with the new Module�
