1. INSTALLATION

1.2 Positioning

The appliance should always be installed and connected to the electricity and gas
supplies by an authorized service engineer. Any subsequent adjustments or conversions
should also be carried out only by qualified personnel.

The standards in force in the country in which the appliance is to be installed should
always be met.

m The combi oven comes with a draft hood as standard. Therefore, the oven may be
vented either under a ventilation hood or by using a type B vent.

m Locate the appliance in properly ventilated premises in order to avoid an excessive build-up of steam.
m Level and adjust the height of the appliance. This can be done by turning the bottom part of the four adjustable feet

(see Fig. 2).

m The combi oven may be installed on a stand. The instructions to assemble the stand and mount the combi oven on

the stand are provided with the stand. The stand could also be used to store sheet and steam pans.

m The appliance has ventilation openings on the left-hand side; so there should be at least 4" of space between the

appliance and any walls or other appliances for the air to circulate freely in that area.

m All combi ovens mounted on stands come with casters as standard. However, combi ovens mounted on stands with

adjustable feet must have at least 18" (45.7 cm) of clearance from the left side and the back for servicing access.

Figure 2.

m The combustible and non-combustible construction clearances should be 0" from the back and 4" from the left and

right side each.

m The appliance should not be positioned in such a way that it can be affected by the steam or heat from other

appliances nearby, especially on the left-hand side.

m The back panel of the appliance should always be in position and properly screwed on, for safety reasons and for the

oven to work properly.

m Keep the oven area free and clear of combustibles.
m Do not obstruct the flow of combustion and ventilation air.
m Keep this manual for future reference.
m Installation shall be made with a connector that complies with the Standard for Connectors for Moveable Gas

Appliances, ANSIZ21.69 (or latest edition) and a quick-disconnect device that complies with the Standard for Quick­Disconnect Devices for Use with Gas Fuel, ANSIZ21.41 (or latest edition)

m Adequate means must be provided to limit the movement of the appliance without depending on the connector and

the quick-disconnect device or its associated piping to limit the appliance movement.

m The restraining means may be attached to the back of the stand.

1.4 Electrical Connection

The electrical connection of the appliance should always be carried out by an authorized service engineer.
The current standards in force in each country regarding connections to electric mains should be taken into account.

m The electrical diagram adhesive label is located inside the control compartment.
m Check that the main’s voltage corresponds to that indicated on the specifications plate.
m This oven is equipped with a 3-prong (grounding) plug for your protection against shock hazard and should be

plug.

m Fit a switch for all phases close to the appliance, with a minimum distance between contacts of 3 mm. This switch

must have fuses.

m This appliance, when installed, must be electrically grounded in accordance with local codes; or, in the absence of

The manufacturer cannot accept any responsibility for damage caused from a failure to observe these grounding
instructions.
