INSTALLATION AND SERVICE
WARNING
IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR
MAINTENANCE CAN CAUSE PROPERTY DAMAGE, INJURY OR DEATH.
READ THE INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS
THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.
Installation and service must be done by specialised technicians. Contact a certified gas technician,
electrician and plumber for set up.
The oven must be connected to the utility and electrically grounded in conformity to the effective
local regulations. If these are not established, the oven must be connected according to the Canadian
Electrical Code (CSA-C22.1-XX) or National Electrical Code (NFPA 70-XX). Refer to last
edition year for XX. Installation must also allow proper access for service (24 inches each side and
back).
The ovens must be installed with a proper ventilation like:
•under a vent hood
•or an exhaust pipe connected directly to the oven chimney flue using the draft hood provided with
the oven.

A4
A type B gas vent approved for use with gas appliances must be utilized.
Make sure that provision for adequate air supply is provided for the operation of the oven.
CAUTION
Make sure that the adjustments mentioned in the "Installation" section are
correctly done prior to firing the oven or converting to a new gas.

A5
DISTANCES TO RESPECT
A) Back and sides of the oven: 1 inch.
B) Top of the oven: a clearance of 12 inches to the ceiling must exist to permit adequate venting
of the exhaust pipe and hot parts and to give proper access to a technician. The draft hood
must have a clearance of 2 inches minimum all around.
C) Floor: 4 inches minimum.
D) Sides of the oven: do not install other than easily removable equipment for service and
maintenance (not closer than 1 inch).
E) It is recommended to have a certain length of water pipe, electric cable and gas pipe between
oven and wall to help gain access for service.

A6
INSTALLATION
IN GENERAL
Take off the packaging material with care. Take off all the material used for packing and accessories.
Install the draft hood on the chimney of the oven.
Each unit is set up to be used with the type of gas and electrical supply specified on the nameplate
fixed on the oven.
The installation must be conform with the National fuel gas code ANSI Z223.1-XX and CAN/CGA-
B149-XX Gas Installation Code and local Codes where applicable. Refer to last edition year for
XX.
The oven's combustion system consists of a very safe gas burner certified in accordance to the
American Gas Association Standard in USA and with the Canadian Gas Association in Canada.
1. To the certified gas technician
The burner installed on DOYON gas fired ovens is set up and adjusted at the plant for a first
class operation. It is nevertheless necessary to verify on site the pressure at the burner input.
The following table indicates the pressures that must be set up to remain conform to the
A.G.A. standards or C.G.A.

The burner used is adjusted to be used with the gas indicated on the nameplate. It is
nevertheless possible to convert the burner to another gas by doing the modifications
indicated in the CONVERSION PROCEDURE provided with the oven. These
modifications must be done carefully and completely under the company's instruction
to remain conform to A.G.A. or C.G.A standards. Refer to Doyon Equipment to get
the right CONVERSION KIT.

A7
The installation must be made with a connector that meets with the standard for connectors movable
gas appliances ANSI Z21.69-XX and a Quick-disconnect device that complies with the standard for
Quick-disconnect devices for use with gas fuel ANSI Z21.41-XX and addenda Z21.41a-XX and
Z21.41b-XX. Refer to last edition year for XX. It must also be installed with restraining device
(chain comes with the oven) to guard against transmission of strain to the gas supply and connectors.
The pipe fittings compound must be certified for gas.
The customer must install a manual shut off valve at the end of the gas supply pipe near the burner
which is approved by the American Gas Association Standard in the United States and with the
Canadian Gas Association in Canada.
Exhaust: A draft hood is provided with the unit and it must be used when the chimney is directly
connected to a gas vent pipe. The exhaust pipe must be certified for use of gases.
Clean the air contained in the gas supply pipe at the installation to insure a successful firing on the
first try. The gas pipe sealing compound tightness must be verified using a solution of water and
soap prior to firing the unit.
WARNING
Make sure not to obstruct the overpressure opening on the gas regulator.
NOTE: If there's any modification done to the system or change of the type of gas used,
make sure that the regulator pressure of the burner is adjusted as recommended in this
manual.
2. To the electrician
Electrical supply installation must be in accordance with the electrical rating on the nameplate.
WARNING
The electrician must make sure that the supply cable does not come in contact
with the oven top which becomes hot.
3. To the plumber
This equipment is to be installed to comply with the applicable federal, state or local plumbing codes.
Connect the steam system (1/4 NPT) to the cold water distribution network.
We highly recommend a water softener to eliminate minerals in the water. We suggest you to use
CUNO # CFS6135 (Doyon part number PLF240).
WARNING
Do not adjust the needle valves, it has been done at the factory.

A8
OPERATION OF THE OVEN
1. Turn the switch to the " ON " position.
•The light inside the oven must light up.
2. Adjust the thermostat at the desired setting (see THERMOSTAT INSTRUCTIONS below).
N.B. The red light must be "ON" (If not, press the breaker on the front).
3. Heat the unit until you reach the baking temperature.
When the desired temperature is reached, the red light goes out and turns green.
If the light is still "ON" and the oven does not produce heat, call for service.
4. Load the oven as fast as possible to avoid letting out too much heat.
5. Set the timer to the desired value and start it. (see "TIMER" adjustment on next page).
NOTE: The timer does not shut the oven off at the end of its cycle. It simply activates the buzzer.
6. Wait until the product is ready. Do not open the doors until the product is done.
VERY IMPORTANT
This oven has an overheat warning alarm to protect the electrical components against overheating. If
the red pilot light (OVERHEAT WARNING) is lit and you hear a buzzer, see troubleshooting.
THERMOSTAT INSTRUCTIONS
To obtain a very good thermal stability, we use a digital temperature controller with thermocouple.
The Omron E5CS thermostat controls the heat of every element at the SP (set point).
The temperature of the oven is always shown on the display of the thermostat and an arrow indicates
if the temperature is over or below the SP. When the green light is lit, it indicates that the temperature
is at the SP ± 1 %.
To adjust the SP (set point) value, you just have to press the key on the left and use the up and down
keys to set the temperature. Press the left key to return to run mode.
