Gas installation

• 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 U.S. or with the Canadian Gas
Association in Canada.

• Plug the oven to the gas supply.

(The pipe, the fittings and the compound must be certified for gas.)

• The gas pipe sealing compound tightness must be verified using a solution of water and soap prior

to firing the unit.

• Clean the air contained in the gas supply pipe at the installation to insure a successful firing on the

first try.

WARNING

Make sure not to obstruct the overpressure opening on the gas regulator.

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.

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.

A phase sequence and loss of phase relay is installed on 3 phases models to avoid wrong rotation
direction of the blowers. If the oven does not light up, swap two phases conductors in the supply
box and try again. Be sure that the power is really on the 3 phases wires next to the fuses in the
control compartment on the front of the oven. Check also if the control fuse located near the main
switch is not blown.

3. To the plumber

This equipment is to be installed to comply with the applicable federal, state or local plumbing
codes.

• Connect the water supply pipe to the oven using good quality sealing compound. Take care

that combustible water pipes do not come in contact with hot parts on the top of the oven.

• Check for leaks of solenoid valve.

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).

Note: The water flow valves for steam have been adjusted, DO NOT TOUCH.

A8

OPERATION

1. Turn on the ventilation system if necessary.

2. Turn on the oven.

• The red pilot light should light up;

• The inside lighting should light up;

• The blowers come on and the rack support starts to rotate if the door is closed properly.

3. Adjust the thermostat to the desired temperature.

4. Preheat function can be used as needed. (see Preheat Instructions)

5. Open the door two inches wide and wait until the blowers stop. Load the oven as fast as
possible to avoid letting out too much heat. When the door is open, the rack support continues
to turn and stops at the position where you can insert the rack.

The temperature will drop. It is perfectly normal as it needs a lot of heat to resume, because of
the introduction of cold air and cold material in the oven. You will realize that this has no
influence on the oven cooking quality which is excellent on all aspects.

6. If required, start the steam cycle immediately after loading. Set the steam timer and press
START. Ex:20.00 = 20 seconds.

A water spray comes in the blowers and in the oven walls. The water vaporizes in the heat and
spreads uniformly in the oven.

If required, to allow the steam to evacuate, the user can open the steam evacuation trap located
in the chimney, by using the handle on the right front top of the oven. This trap should be
closed after being used to keep heat inside the oven. We suggest you to open the trap 2 or 3
minutes after having injected steam, open it for 15 seconds and then close it.

A waiting cycle follows, then the blowers and the burner stop for a moment (approximately 45
seconds).

The blowers come back on and the burner starts.

7. Wait until the products come to a light-medium brown. If desired, you can use the baking
timer on the front panel. Adjust the time and press the start button. Ex: 2015 = 20 minutes and
15 seconds.

NOTE: The timer does not shut off the oven at the end of its cycle. It simply activates the

buzzer.

A9

POWER FAILURE

The burner, the electric gas valve and the regulator are all designed to be failed
safe. There is no special action to take in case of electrical power failure.

8. To stop the oven, set the selector switch to the position "OFF". The oven has been designed to
keep the burner blower running for 30 minutes after it has been shut off. This allows the oven
to cool down.

A10

PREHEAT INSTRUCTIONS

To use the PREHEAT function, push the preheat switch to start. The preheat function will stop
automatically when the door is opened. This is the only way to stop the preheat function.

In order to avoid a temperature drop when loading your next baking, maintain the temperature

0

75

F degrees higher than needed between two baking by using the preheat function.

0

Example : 375

NOTE: The "shift" light is lit when the preheat function is on.

F degrees temperature using preheat function will rise the temperature at

0

TROUBLESHOOTING

BEFORE CALLING FOR SERVICE

ANSWERS TO MOST FREQUENT QUESTIONS

Always cut off the main power before replacing any parts. Take care of water and gas
piping system when servicing.

Control parts are under the left front
bottom panel and under the control panel.

Gas and motor systems are on the top of the
oven.

Questions Solutions

The oven temperature drops when loading
and needs a certain amount of time before it
stabilizes.

The oven does not turn on.

Remove the front panels by screwing out the
only screw on each panel.

It is usually not necessary to remove the hood.

This is normal. The opening of the door
produces an important loss of heat. The rack
loaded with cold pastries need a large amount
of heat to get back to its original temperature.
The same thing happens with domestic ovens.
You will realize that your new gas oven can
provide an excellent baking quality for any kind
of products you want to bake.
If the oven is turned on for the first time and
nothing happens, just reverse the two phases
feeders in the main supply box. A phase
sequence relay is installed on the oven to avoid
burner fan to turn in the wrong direction.

The oven does not produce heat.

• The burner goes to lock-out because of:

If the oven has already functioned, check the
motor fuses and the overload relays located in
the electrical control panel. Turn the main
power off to replace the fuses.
Make sure that the door is closed and the
thermostat adjusted to the desired temperature.
(You can hear the oven blowers.)
If the oven blowers are not on, check the
overload relays located in the control
compartment. If anyone of these is disengaged,
call for a qualified technician.
If the blowers run normally, make sure that the
gas valve is open.
The burner is equipped with multiple

A16

interlocked safety devices. In the event of a
failure of the flame or any blockage of the
combustion air supply, the burner will "lock
out" in the safety condition.

a) Flame failure:

b) The spark is irregular or not present:

• Air has not been bled from the gas line.

• Porcelain insulators cracked (very little

cracks is enough).

• Spark probe grounded.

c) The air pressure switch does not close its
contact.

• It may be disconnected, incorrectly set,

defective, or the burner fan can be dirty and
does not produce enough vacuum.

The steam system does not react correctly.

Check if the water supply is connected and the
input valve opened.

Call for a qualified electrician or plumber if
required.

Keep the air inlet of the burner free of obstruction.

CAUTION

Never try to modify the burner controls. This must be done only by a qualified
technician and under the company's instructions.

A17

MAINTENANCE

MAINTENANCE OF THE OVEN

• Grease regularly as shown in "LUBRIFICATION AND ADJUSTMENT" section.

• Use only grease provided with the oven.

• It is recommended to use a water filter to avoid accumulation of minerals inside the oven

during the use of the steam cycle.

MAINTENANCE OF THE BURNER

• Every three months, verify and clean the burner air inlet in order to remove dust and particles.

• Once a year, you should ask a certified technician to make a tune up.

Make sure everything works properly, verify and clean especially:

1. The gas mixer.

2. The spark rod and porcelain insulators.

3. The flame detection rod.

4. Verify the burner input pressure.

5. Verify every adjustments.

6. Clean every moving pieces.

7. Lubricate the motor.
