INTRODUCTION
WOOD STONE OVEN SERVICE MANUAL INTRODUCTION
Welcome to the Wood Stone Oven Service manual. This manual covers the Fire Deck line of gas-fired and gas/wood
ovens. If the unit you are servicing does not appear in this book please call our Service Department for assistance. This
manual is for use only by Trained and Qualified Service Personnel.
WARNING! Improper installation adjustment, alteration, service or maintenance can result in property damage, injury or
death� Please read and understand all pertinent instructions before attempting to install or perform any kind of service on this
equipment� BE SAFE�
PRODUCT OVERVIEW
The Fire Deck ovens are available in a wide variety of gas and solid fuel configurations.
BURNER FUNCTION
Radiant Flame Burner (RFG): When equipped, the Radiant Flame Burner is the main heat source for the oven, and it runs
continuously when the oven is turned on� Fire Deck ovens will often have multiple RFG Burners� To control temperature, Flame
Height Control Knob(s) are provided at the front of the oven� There is no thermostatic control for the Radiant Flame Burner;
the operator manually adjusts the flame height with the Flame Height Control Knob to control the temperature of the
oven.
Infrared Burner (IR): The IR is installed beneath the floor of the oven� It is controlled independently of the Radiant Burner by a
temperature control located in the oven Controller box� This box is located on the front of the oven� The Controller incorporates a
programmable Hearth Set Point and a Hearth (floor) Temperature Display� Remember the Underfloor IR Burner is not the primary
heat source for the oven�
SOLID FUEL OPTIONS
Wood (-W): Models that are equipped with the Radiant Flame Gas Burner (-RFG in the model number) and include a (-W) in the
model number are configured to allow for wood burning, up to a specified amount as detailed in the Installation and Operation
Manual for that model� In this configuration the wood IS NOT the primary heat source—the gas Burner still provides the majority
of the heat�

GAS-FIRED OVENS
Wood Stone manufactures two different model types of CE gas fired-ovens�
1. Radiant Flame Gas (RFG): This model uses a Radiant Flame (dome flame) Burner that is designed to give the appearance of
a wood fire� This Burner is the sole heat source in these models� Some variations of this model type may have multiple Radiant
Flame Burners�
2. Infrared Burner (RFG-IR): This model type incorporates both an Underfloor IR Burner and at least one Radiant Flame (Dome
Flame) Burner� The Radiant Flame Burner is the main heat source in this oven� The thermostatically controlled, Underfloor IR
Burner is usually only activated during times of peak use and at the beginning of the day when the oven is first turned ON�
BURNER FUNCTION
Radiant Flame Burner(s): The Radiant Burner, located at either side, or both sides, of the oven, is the main heat source for the
oven, and it runs continuously when the oven is turned ON� The control for the Radiant Flame Burner is the Flame Height Control
Knob, located on the front of the oven, on the side the burner is located� There is no thermostatic control for the Radiant Burner—
the operator manually adjusts the flame height with the Flame Height Control Knob to control the temperature of the oven�
Infrared Burner (IR): The IR Burner is installed beneath the floor of the oven� The IR is controlled independently of the Radiant
Burner by a temperature control located in the oven Control Box� This box is usually located on the front of the oven, but sometimes
this might be moved to a different spot to accommodate the type of installation� The Controller incorporates a programmable Hearth
Set Point and a Floor Temperature Display� Remember the IR Burner is not the primary heat source for the oven�

GAS OVEN COMPONENTS
GAS OVEN COMPONENTS
The following is a list of the key electrical and gas components found in Wood Stone gas ovens, accompanied by
information about the individual parts:
24 VAC TRANSFORMER
This is the power supply for all of the electrical components on the oven� It converts the incoming 230 VAC power to 24 VAC�
TRANSFORMER PLATE ASSEMBLY (PRIOR TO MAY 2015)
TOUCHPAD CONTROLLER
The Type 2 Controller (shown below) is used on RFG-IR and W-IR gas ovens� On the front of the Controller is a Lexan Touchpad
with a Hearth Temperature Display and Hearth Set Point buttons and display, Dome Flame and Hearth Heat Indicator Lights, and
ON/OFF and Celsius / Fahrenheit functions�
DIP SWITCH SETTINGS
The larger Type 2 Controller has DIP
switches on the back of the board that
must be set for the appropriate oven
model as shown below:
RFG-IR: Both ON
W-IR: #1 OFF, #2 ON
The Transformer Plate is located beneath the oven in the front, on the right
hand side� Mounted to the Transformer Plate are two Junction Boxes� The larger
Junction Box contains the 24 VAC Transformer, a Line Filter, 1 A fuse for the
incoming power, 5 A fuse for the 24 VAC Transformer output, and a Terminal
Strip for the incoming power connection�
Low voltage wiring for the oven is routed through the Terminal Strips in the
smaller Junction Box located towards the front of the Transformer Plate� It
allows easy voltage testing of various oven components for troubleshooting�
Do not alter any wiring within this box� Under no circumstances should 230
VAC wiring be connected or routed through this box! No external equipment
should be connected to the low voltage wiring of the oven� This may effect the
operation of the oven and may void the oven warranty�
TRANSFORMER PLATE ASSEMBLY (AFTER MAY 2015)
The Transformer Plate is located beneath the oven on the back stand� It consists
of one of the two types of transformers within an 203 x 305 mm (8 x 12")
Junction Box� It allows easy voltage testing to various oven components for
troubleshooting� All wiring harnesses and the Thermocouple are routed through
terminal strips within this box�
Do not alter any wiring within this box or on the oven� No external equipment
should be connected to the low voltage wiring of the oven� This may affect the
operation of the oven and will void the oven warranty�

GAS OVEN COMPONENTS
GAS SYSTEM COMPONENTS
GAS VALVES
All Wood Stone CE model ovens use the same type of combination Gas Valve, regardless
of the Burner� An adjustable pressure regulator is incorporated into the valve� Maximum
incoming line pressure to the oven must not exceed 14" W�C� (34�8 mbar)� If the line
pressure is too high, a Regulator must be installed in the incoming line� There is also
an adjustment for the Pilot Flame height on this valve as well� The valve is powered
and controlled by a separate Ignition Module (ICS)� On all wiring diagrams and in this
manual, the valve for the Underfloor IR Burner is referred to as SV-1� Radiant Burners are
numbered SV-2, SV-3, etc�
IGNITION CONTROL SYSTEM (ICS)
There is one ICS Module for each Burner on the oven� Each Module receives 24 VAC from
the oven Control Board� When the Module is powered, it sends spark to the Igniter and
powers the Pilot Solenoid on the Gas Valve� When the Module senses flame rectification
at the Pilot, it stops sending spark to the Igniter and powers the Main Gas Valve firing the
Burner�
PILOT IGNITER ASSEMBLY
The Pilot/Igniter is used in conjunction with the ICS Module to ignite the Burner and
provide flame sensing (flame rectification) for the Gas Valve� Ignition is of the spark-to-
Pilot type� Flame rectification is achieved from the spark rod to ground� A single wire
connects the Pilot Igniter to the ICS Module� This wire carries both spark and rectification
current� A Pilot Orifice is installed in line between the compression fitting and the body of
the Pilot Igniter Assembly� Use the correct orifice for the gas being used�
RADIANT BURNER ASSEMBLY
This is the Burner located at the side(s) of the oven and produces the
flames visible inside the dome� It consists of a stainless steel Burner
housing, a cast iron Burner Manifold, the Burner Jets and the Flame
Retention Springs that are attached to each Jet� There is an opening in
the Burner housing through which the Pilot Igniter Assembly is mounted�

GAS OVEN COMPONENTS
INFRARED BURNER ASSEMBLY
This is the Burner located beneath the floor of the oven� The tubes on the
outside of the Burner are used to supply air to the Burner� You will not
see flame in these tubes� DO NOT ATTEMPT TO LIGHT THIS BURNER
MANUALLY! To visually verify that the Burner is running, look through the
gap next to the Pilot assembly and you should see a reddish glow over
the ceramic Burner elements� This Burner operates only when the hearth
temperature is lower than the Controller’s Hearth Set Point�
THERMOCOUPLE
A Type K Thermocouple is used to sense the temperature of the oven floor
(hearth) about 25mm (1") beneath the hearth surface� It is located slightly to
the rear of the center of the oven (behind the IR Burner on an IR equipped
oven)� It is embedded in the floor of the oven, but is easily replaceable� On all
CE ovens, the Thermocouple leads are covered with braided steel sheathing
for EM and RF shielding�
SV-1 AND SV-2 WIRE HARNESSES
These harnesses supply the voltage needed to activate
and power their respective ICS Modules and Gas Valves�
They also send flame verification voltage from the
Module back to the Controller
SV-1 Wire Harness SV-2 Wire Harness
THROTTLE ASSEMBLY
The Flame Height Control Knob for this Valve is located on the front of the oven� This is what the operator uses to control the
flame height of the Radiant Burner only� Ovens equipped with two Radiant Burners will have a separate control for each burner�
It is not a shutoff Valve� Do not remove, or replace this Valve with anything but a Valve supplied by Wood Stone� The use of any
Valve not provided by Wood Stone will negate the CE Listing on the oven and could effect its safe operation.
