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.
The ovens must be installed with proper ventilation like:
•Under a vent hood with outside air exit
•The connection of the exhaust pipe flue is not required.
Make sure that provision for adequate air supply is provided for the operation of the oven.
Do not permit fans to blow directly at the oven and whenever possible, avoid open windows
next to oven sides or back and wall type fans which create air cross currents the room.
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.
INSTALLATION WARNINGS

A-3
A) Back of the oven: 4 inches
B) Top of the oven: a clearance of 12 inches from above the top of the oven must exist to permit
adequate venting.
C) Floor: 4 inches minimum (legs)
D) Sides of the oven: No clearance required from the end of the conveyor. Do not install other
than easily removable equipment for service and maintenance.
DISTANCES TO RESPECT

A-4
IN GENERAL
Take off the packaging material with care. Take off all the material used for packing and accessories.
Each unit is set up to be used with the type of gas and electrical supply specified on the name plate
fixed at the back of the oven.
The installation must be conform with National fuel gas code ANSI Z223.1 and CAN/CGA-B149,
Gas installation Code and local Codes where applicable.
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 AGA
standards or CGA.

The burner used is adjusted for use 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.
INSTALLATION

A-5
The installation must be made with a connector that meets with the standard for connectors movable
gas appliances ANSI Z21.69 and a Quick-disconnect device that complies with the standard for
Quick-disconnect devices for use with gas fuel ANSI Z21.41 and addenda Z21.41a and Z21.41b. It
must also be installed with restraining (like a chain) to guard against transmission of strain to the
connector. 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 Canada with the Canadian Gas
Association.
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.
ATTENTION
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.
•Check if the rotation of the motor is in accordance with the arrow on top of each unit.
If NOT
If the power supply is 3 phases and the unit is not connected in the right phase
sequence, the fan motor will turn the wrong way. This will affect the baking quality.
Turn the power "OFF" and change the phase sequence.
WARNING
The electrician must make sure that the supply cable does not come in contact with the
oven top which becomes hot.

A-6
1. Turn the switch to the position "ON".
2. Adjust the thermostat at the desired temperature (see THERMOSTAT INSTRUCTIONS below).
3. Adjust baking time according to your product. Use the up and down arrows on the speed control
to set your baking time.
(see suggestions in the tables next page.)
N.B. The thermostat display must be "ON" (If not, press the breaker on the front)
4. Heat the unit until you reach the baking temperature.
When the desired temperature is reached, the red light ON goes out on the thermostat.
•If the red light on the front control panel is "ON" and the alarm buzzer rings, the oven does not
produce heat. To start it over, press the red button on the front control panel for 2 seconds. The
burner will start up (you can hear it). You can repeat this operation three times. If it does not
start up again, contact our company or a certified gas technician.
5Place your products on the conveyor.
We recommend to use perforated pan or pizza screen.
6 To stop the oven, just turn the selector switch to "OFF" position. If the control compartment is too
hot, the cooling fan will run until the temperature drops.
THERMOSTAT INSTRUCTIONS
To obtain a very good thermal stability, we use a digital temperature controller with thermocouple.
The Omron E5CS thermostat controls the heat 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 value, you just have to press the key on the left and use the up and down keys to set
temperature and alarm value. Press the left key to return to run mode.

NOTE: In order to remove the conveyor, it is necessary to be two people.
1- Place the oven main switch [A] to the position "OFF" (see drawing next pages).
2- Make sure that the oven has cooled down completely.
3- Disconnect the yellow plug of the conveyor motor [B] (unscrew the plug).
4- Remove the two crumb tray located under the conveyor [C] (lift it approximately 1/2
inch (1cm) and remove).
5- Take out the screws which hold the two finishing plates on each side of the conveyor
[D] and remove the finishing plate. [E]
6- To take out the conveyor, it takes two people, one at each end. The person who is at
the opposite side of the gear motor of the conveyor raises it 1 inch (2 cm) and pushes
it towards the front. When the end of the conveyor is inside the oven, it is preferable
that the same two people place themselves on each side of the conveyor and continue
to pull with precaution to take out the conveyor completely.
7- To re-install the conveyor, repeat the instructions above in reverse.
Note: It is possible to reverse the conveyor. When you are ready to re-install, just enter it at
the opposite side of the oven.
