INFRARED BURNER TROUBLESHOOTING
Many Wood Stone ovens are equipped with an Underfloor Infrared (IR) Burner� The IR Burner is designed to assist the Radiant Burner
or the wood fire during start-up and during times of heavy usage� It is thermostatically controlled� It is not the primary heat source
for the oven� The IR Burner’s Gas Valve and Pilot/Igniter are identical to those used on the Radiant Burner�
RFG-IR Models
IR Burner is not lighting� The display
may be flashing “check”�
NOTE:
You will not see flame at the
black tubes on the front of the Burner�
CAUTION:
Never attempt to light this
Burner manually� To visually confirm
that the Burner is lit, look through the
gap next to the Pilot/Igniter�
Is the Radiant Burner running?
If not, proceed first with Radiant Burner
troubleshooting� See previous pages of this manual
NOTE: On RFG-IR ovens, the IR Burner will not light until the Controller has
verification that the Radiant Burner has lit, or one of the Radiant Burners on ovens
with 2 Radiant Burners�
If the Radiant Burner is running, and the Controller is calling for IR heat, it will
allow the IR Burner 90 seconds to light� If the Burner has not lit after this time the
Controller will flash “check”� Turn the oven off and then back on to reset�
1.
If the Radiant Burner is running, is the Controller calling for heat, i�e� the Hearth
Temperature is lower than Hearth Set Point?
2.
Is the switch on the Honeywell Gas Control Valve in the “On” position?
3.
Visually check for Igniter glow� If the Igniter does not come on when the IR
Burner is called for, check that the MOLEX connectors are securely plugged
into the Gas Control Valve� Make sure that the pins are securely locked into the
connector body� Remove any wire ties and uncoil the Igniter wires so that there
is minimal contact between them� Check the continuity of the Glow Coil at the
two adjacent wires on the Igniter connector; this should be approximately 3�5
ohms� If the circuit is open, replace the Igniter� If Glow Coil tests OK, disconnect
the SV-1 wire harness from the Gas Valve and with the Controller calling for
heat, test for 24 volts between the yellow and white wires, and brown and white
wires� Do not test for voltage at the connectors on the Gas Valve; damage to
the Valve may result� If voltage is not present, see Controllers Troubleshooting
section of this manual� If voltage is present replace the Igniter� If there is still no
glow, replace the Gas Valve�
4. If the Igniter is glowing and the gas supply to the oven is good, but Pilot is
still not lighting: Remove the Igniter and inspect for damage and/or a plugged
orifice� Replace if necessary� If Pilot orifice is not plugged or damaged, replace
Gas Valve�
Burner will not light or shuts off
sometimes, and, the Igniter wires
appear to be burned� 1. Loose Pilot Tube: Tighten and replace Igniter�
2. Inadequate oven venting or negative air pressure: See Installation and Operation
manual instructions� Call Wood Stone for information�
