Burner does not light, oven Controller
is on, no spark at the Pilot�
Ignition (ICS) Modules
There are 2 versions of the ICS
module that have been used on
these ovens� Functionally they are
similar, however there are slight
differences in the wiring connections,
and differences in the functions of
the indicator lights� The Robertshaw
module has been used for a number
of years, more recent models will be
equipped with a Fenwal module� The
Robertshaw model may be replaced
with a Fenwal, but will require a
slight wiring modification, a Wire
Harness kit is available from your
distributor�
Note: If the Radiant Burner will not light, stay lit, or is going out intermittently,
the Radiant Burner should be removed for inspection and cleaning before
proceeding with additional troubleshooting� The majority of Radiant Burner
problems can be traced to debris in the Burner� See the “Repair Procedures”
section of this manual�
1. Check Igniter�
a. Inspect the Igniter for damage� Unplug the the Igniter lead and check for
continuity between the terminal end and the electrode� Replace Pilot/
Igniter Assembly if it is damaged�
2. Check ICS module�
a. When the oven is on, there should be 24 VAC present between the TH
and GND terminals on the module�
Robertshaw module: LED should be lit when 24 VAC present at the
Valve�
If LED is flashing, module has locked out. Turn off power to the oven for
5 seconds to reset�
Fenwal Module: LED is OFF when the module is functioning normally�
If LED is ON, there is an internal failure in the module and it must be
replaced� If LED is flashing 3 flashes in succession the module has locked
out� Turn off power to the oven for 5 seconds to reset�
b. If 24 VAC present at the ICS module (either type) between terminals TH
and GND: Turn the oven OFF� Disconnect the Igniter lead from the module�
Turn the oven back on� Within a few seconds you should here a distinct
repetitive clicking sound from the module indicating that it is creating
spark� If there is no clicking sound, replace the module� Before installing
new module, check Igniter and Gas Valve for shorts to ground and if
shorted replace accordingly�
3. Check Controller�
When oven is turned ON there should be 24 VAC at the output terminals
on the Controller (Brown and White wires)� If 24 VAC not present when
Controller is turned ON, replace Controller�

1. Gas supply to the oven has been turned off. Check manual shutoffs, fire
suppression system resets etc�
2. On a new oven, start-up there may be air in the Gas Line. Turn the oven on for
about 30 seconds� Turn it back off and then back on for 30 seconds� If oven does
not light after repeating this, verify that there is gas to the oven at the inlet tap on
the Roberstshaw Gas Control Valve�
WARNING: To prevent risk of explosion or fire, turn off the oven Controller and
extinguish all open flames before opening the pressure tap. Do not leave the
oven unattended while this tap is open.
Open the pressure tap and check if gas is present� If necessary� blead the line
until gas is present� Make sure any gas in the air has cleared before attempting to
restart the oven�
3. Debris in Burner. If the Radiant Burner will not light, stay lit or is going out
intermittently- the Radiant Burner should be removed for inspection and cleaning
before proceeding with additional troubleshooting� The majority of Radiant Burner
problems can be traced to debris in the Burner� See the “Repair Procedures”
section of this manual� While the Burner is removed check the Pilot Orifice to make
sure it is not obstructed�
4. Bad Pilot Igniter. Inspect Pilot Igniter for damage, cracked insulator etc� Clean
Flame Rod if necessary�
5. Check Gas Valve. Check connections to the Pilot Solenoid and the main Gas
Solenoid on the Gas Valve� When Igniter is sparking there should be 24 VAC at the
Pilot Solenoid on the Gas Valve (D and D+ terminals on Valve)� You should hear the
Pilot Solenoid click when power is first supplied to the Valve� If no click - replace
Valve� If a click is heard and the Igniter is sparking but Pilot is not lighting, see Pilot
adjustment instructions below�
6. Pilot Adjustment. If the Pilot is adjusted too high or too low, it will not make proper
contact with the flame sensor rod� The Pilot adjustment screw is located beneath
the small cap on the Gas Control Valve� Turn the adjustment screw clockwise
to decrease gas-flow to the Pilot� To find the proper Pilot adjustment, turn the
adjustment screw fully clockwise� Then turn the oven ON� When you hear the
Igniter begin to spark, gradually turn the the adjustment screw counter-clockwise
until you hear the spark stop� The Pilot should be lit and within a few seconds the
main Burner should light�

TROUBLESHOOTING GUIDE

1. Verify that gas is going to the Burner using a manometer at the outlet port of the
Gas Control Valve�
Check the Equipment data plate beneath the oven for the specified pressure�
Adjust the Regulator on the Gas Valve if necessary�
If pressure is extremely low or non-existent, verify that there is sufficient pressure
at the inlet side of the Gas Valve�
If inlet pressure is too high (higher than 34�8 mbar, 0�5 psi) the oven will not
function properly� If inlet pressure to the oven is over 34�8 mbar (0�5 psi) an
external Pressure Regulator must be installed for the oven to work properly and to
avoid damge to the Gas Valve�
If inlet pressure is good, check all wiring connections at the Valve and the ICS
module�
Check for 24 VAC between TH and TR on the Gas Control Valve�
If voltage is present and no gas flow at the Valve outlet, replace the Gas Valve�
If no voltage present, and Pilot is lit, replace ICS control module�
2. If proper gas pressure is found to the Burner, drop the Burner and clean, make sure
all Jets are clean and that the Pilot/Igniter has not been knocked out of position�
The base of the Pilot/Igniter Assembly should be horizontal, even with the top of the
Burner�
Burner is not lighting, but Pilot is
lighting�
7. Air movement beneath the oven. When properly installed there should be no air
movement beneath the oven� If their is air movement it will likely cause lighting
issues with the Pilot and the Burner� The only pathway for air to the space beneath
oven should be the serice panel on the front of the oven� Make sure that the rear
stand panel is installed�
8. Excessive ventilation. If the venting system is pulling too much air through the oven
flue the Pilot and Burner can be disrupted� The fan for the venting system should be
adjusted so that it is pulling the minimum amount of air to capture smoke and fumes
from the oven�
9. Air blowing at the oven opening. If air is blowing at the oven opening from a vent,
doorway etc�, the airflow can disrupt the Pilot and Burner�

Door(s) in place!
1. Debris in the Burner causing the Pilot to lose rectification. Remove the Burner
and clean, see the Repair Procedures section of this manual� Make sure the Igniter
is not damaged and that the Flame Rod is clean�
2. Gas supply to oven is being interrupted or is inadequate, or Burner gas pressure
is set incorrectly. Verify the Burner gas pressure with the flame turned all the way
up� If the correct pressure (as shown on the oven data plate) cannot be obtained,
the gas supply is inadequate� Check for undersized Piping, shut off Valves, etc�
3. Incorrect Pilot adjustment. Adjust Pilot height at the Gas Valve� Turn the
adjustment screw in (clockwise) until the Pilot goes out� Then back the screw out to
just beyond the point where the Pilot relights�
4. Excessive venting causing the Pilot flame to lift away from the Flame Rod.
Correct the airflow problem and make sure the Igniter gasket is in place� There
should be no discernible airflow beneath the oven�
5. Defective Pilot/Igniter, replace. If Burner is still cutting out, replace Gas Control
Valve�

NOTE: Remove the front panel on the oven to access all components�
CHECKING BURNER GAS PRESSURES
Proper gas pressure settings and an adequate incoming gas supply are critically important for any gas-fired Wood Stone oven to
operate correctly� Burner gas pressure measurements should be taken at the outlet port on the Gas Control Valve� Make sure that
the Throttle Valve is fully open (maximum flame height) when taking the pressure reading� When it is suspected that the incoming
pressure is inadequate, test the incoming pressure (at the inlet port on the Gas Valve) with the oven off, and then with the oven on and
the Burner running� If the incoming pressure drops significantly with the oven running, and the proper pressures cannot be obtained
at the Burner, the gas supply is inadequate� Look for Regulators external to the oven that are set too low, partially closed Valves or
undersized Piping� The Piping and shutoff Valves supplying the oven must have a minimum O�D� of 3/4" (19mm) - the same as that
of the inlet connection on the oven� Depending on the length of the pipe run, it may need to be larger in diameter� Consult a qualified
gas Piping installer to deal with any supply Piping issues� The specified pressure for the Burner may be found on the Equipment
Nameplate, located on the back of the Control Box, in the compartment below the oven�
REMOVAL AND CLEANING OF RADIANT BURNER
This procedure may be performed while the oven is hot� We strongly recommend that the technician wear heat protective gloves and
safety glasses/goggles when removing the Burner�
1. For Burner removal, first turn the oven off� Turn off the gas supply to the oven�
2. Unplug the Igniter sensor wire from the oven Control Box�
3. Disconnect the Pilot Tube at the Gas Valve, or if there is a union in the Pilot Tube, it may be disconnected at the union�
4. Disconnect the Flexible Gas Piping where it attaches below the Burner�
5. From beneath the oven, carefully remove the four bolts holding the Burner Assembly in place and lower the Burner out of the well�
Caution: Watch out for falling debris while removing the Burner�
6. Clean off any debris on the Burner�
7. Check that Burner Jets are not blocked, and that the Pilot/Igniter Assembly is not dirty or damaged� If removing Igniter, be aware of
the Pilot Orifice, which slips into the Igniter where the Pilot Tube is attached and can fall out if you are not careful� Any Burner Jets
that are clogged should be removed from the Burner manifold to prevent debris entering the manifold while cleaning� To remove the
Jets, first remove the flame retention spring attached to each Jet by gripping the spring with a pair of pliers and pulling away from
the Burner while turning the spring clockwise� Then remove the two brackets that hold the Burner manifold in place� Remove the
manifold, then remove the individual Jets� Use a piece of wire to clean out the Jet� Make sure to reinstall so the hexagonal part of
the Jet is closest to the Burner manifold� Make sure to reinstall the flame retention spring�
Note: On BL-4355-LR models built after March 2017, there will be a 7/16" SS Washer on the top of each Burner Jet�
Make certain the washer is in place before reinstalling the Burner Manifold (see drawing below)�
8. To reinstall Burner follow the removal steps in reverse�
9. Check for gas leaks using soap solution with the Burner running�
Avoid getting soap solution on Valve or Igniter Wires�
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 above� While the Igniter can be
replaced without Burner removal, we find that the cause for the Igniter failure is
commonly 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 Assembly with a right angle
bracket� Remove the screw holding the bracket to the Burner can, 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�

3. Loosen the retaining nut that secures the Thermocouple to the bottom of the oven�
4. Slide the Thermocouple out and remove the old fitting from the oven floor�
5. Using the Compression Fitting supplied with the new Thermocouple, slide the new unit in as far as it will go, then check your
