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.

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.
