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

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.
