3. COMBUSTED GAS DISCHARGE
3.1 FOREWORD
In relation to the combustion technology utilised, gas fired steam/
convection ovens are classified in accordance with their
"Construction Type". For each of these types of appliances
applicable regulations stipulate a specific type of combusted gas
discharge system.
Consequently, before installing the discharge system:
a) identify the "Construction type" of your model in Table 1
(technical data) or by checking the appliance identification
dataplate;
b) choose the diagram with the type of construction among
those shown as follows (fig. 1a-1b-1c), depending on how you
intend to exhaust the appliance fumes from the place of installation
(e.g. discharge under extraction hood, direct to the outside, or in
a central flue).
5938 026 00

USA
3.2 WARNINGS REGARDING THE FLUING SYSTEM
Before installation check, on the basis of the contents of the
reference standard, to ensure that the volume aspirated by the
fumes exhausting system is greater than the volume of combusted
gas produced by the appliance (see point 1.1).
If the solution of combusted gas discharge under an extractor
hood is chosen, observe the distance (shown in the figure)
between the top of the discharge pipe and the lowest point of the
hood filters. This distance is defined on the basis of discharge
pipe diameter "D".
In the case of discharge direction to the outside or into a central
flue (Fig. "1c"), the discharge ducts must NOT present an overall
length in excess of 762"(3 metres), must NOT have any reductions
in diameter, and must be subjected to periodic inspection and,
when necessary, cleaning.
Warning:
high temperatures, check the heat resistant properties of
extension ducts if fitted and the filters in the extractor hood
to ensure the materials are compatible with the temperature
conditions. In addition, periodically check the condition of
the filters which, if excessively fouled with fat and dirt, will
reduce the efficiency of the suction system and may catch
fire.
Since combusted gas (see figure) can reach very

4. ELECTRICAL CONNECTION
• A fused disconnect switch or main circuit breaker (customer
furnished) MUST be installed in the electric supply line for the
appliance. It is recommended that this switch/circuit breaker
have lockout/tagout capability. Before making any electrical
connections to this appliance, check that the power supply is
adequate for the voltage, amperage, and phase requirements
on the rating plate.
• A safety cutout switch of suitable capacity with a contact
breaking distance of at least 3 mm must be fitted upstream of
the appliance.
The cutout switch must be installed near the appliance in the
permanent electrical system of the premises.
• The appliance must be electrically grounded in accordance
with local codes, or in the absence of local codes, with the
National Electrical Code, ANSI/NFPA 70, or the Canadian
Electrical Code, CSA C22.2, as applicable.
The grounding conductor must therefore be connected to the
terminal marked Gon the connection terminal board. The
appliance must also be connected to an earth grounding
system.
This connection is made using the stop screw marked E
located on the outside of the appliance near the power cable
inlet.
The grounding wire must have a minimum cross-section of
8 AWG (10 mm
4.1 INSTALLING THE POWER SUPPLY CABLE
To access the power supply cable connection terminal board,
proceed as follows:
Model 6 - 10 - 20 GN
• Remove the left side panel.
• Connect the power supply cable to the terminal board accord-
ing to the instructions given in the wiring diagram and fasten the
power supply cable by means of strain-relief fitting (not furnished
with the oven).
Failure to comply with safety rules and regulations relieves
the manufacturer of all liability.
The manufacturer requires when stacking units each appliance
have its own branch circuit protection. An air-o-steam® unit
stacked with an air-o-chill® unit should have a separate protection
for the upper and lower units.

Before fitting the filters allow the water to flow out for sufficient
time to flush any solid particles from the piping.
5.1 WATER SUPPLY CONNECTIONS
5.1.1 WATER INLET "N".
Attention
The water supply pipe (not supplied) must have a 3/4" dia (20
mm) pipe and must be without elbow fittings.
The steam condensation system must be connected to a cold
quality water supply in keeping with local plumbing codes, with
the following characteristics:
- total hardness: up to 400ppm (40°fH) .
- pressure: 22 to 36 psi (150-250 kPa); higher pressure
values result in increased water consumption.
Note:
To check correct water installation, make sure the rotating wash
arm (CLEANING SYSTEM) does not turn below 100 rpm (120
max).
5.1.2 WATER INLET "B".
(water pipe supplied)
The steam production system must be connected to a quality
water supply in keeping with local plumbing codes, with the
following characteristics:
- total hardness:
build-up of lime-scale inside the boiler.
On request the oven is supplied with an optional water softener
with automatic regeneration which must be installed on inlet line
"B". This device can also be fitted with an optional resin sanitizer
kit.
- pressure: 22 to 36 psi (150-250 kPa); higher pressure
values result in increased water consumption.
- chlorine ion concentration (Cl -): not more than ~10 ppm
(acceptable value) to avoid damaging the oven's internal steel
parts.
- pH: over 7.
The oven can be equipped with an optional special filtration unit
which is installed on inlet line "B". This unit also acts as a water
softener, reducing water hardness to less than
(optimum value).
- electrical conductivity: 50 to 2000 µS/cm (68°F)(20°C).
Important: The use of water treatment systems featuring
technology that differs from that of the systems supplied by the
manufacturer is prohibited and will automatically invalidate the
warranty.
The use of dosing systems designed to prevent the buildup of lime-scale in pipes (i.e. polyphosphate dosing
systems) is also prohibited since such systems may impair
the performance of the appliance.

5. WATER MAINS CONNECTION
(Refer to the installation diagrams at the beginning of this booklet).
This equipment is to be installed to comply with the applicable
Federal, State, Local plumbing codes, or the Basic Plumbing
Code of the Building Officials and Code Administrators
International Inc. (BOCA) and Food Service Sanitation Manual
of the Food and Drug Administration (FDA).
The appliance is fitted with two separate water inlets ("B" and "N").
The water lines supplying both inlets must be fitted with a
mechanical filter and shut-off valve (keeping with local plumbing
codes).
5.2 WATER DRAIN SYSTEM
The oven is supplied with an air-break system to prevent any
backflow from the drainage system from reaching the oven’s internal circuits and the cooking chamber. The presence of this
system means that the drain pipe can be connected directly to
the mains drainage system or routed to a floor gulley with grating.
The flexible drainage hose or rigid pipe can be directed to the
side or rear of the appliance if the oven is not positioned against
a wall; this line must not be directed towards the front of the
appliance to prevent interference with roll-in grid racks. The drainage pipe internal diameter must be no smaller than the oven
