INSTALLATION

II.INSTALLATION, PREPARATION, AND SUPPLY

When preparing the oven for installation at a location, the latest International, National or Local Requirements should be adhered to.

The ovens must be installed on an even (level) non-flammable flooring and any adjacent walls must be non-flammable. The minimum allowed distance from the rear of the oven to the wall is 12” (30cm).

The ovens can be supported only by legs. No casters are allowed. It should be made certain that there are no obstructions located around or underneath the oven that interfere with air circulation.

The ovens must be installed under a ventilating hood with electrical exhaust air sensing control.

The gas supply connection should be according to applicable

ISO-228-1 or ISO-7-1 recommendations.

Normally, the oven is preparted and adjusted to the specific gas type used by the customer. Before operating the oven, check the label on the oven and also on the packaging that the gas type indicated matches the local supply at the installation. If not, refer to Section VI, PREPARATION FOR VARIOUS GASES, in this chapter and convert as directed.

All installations, conversions and service work must be performed by an Authorized Service Agent according to the instructions supplied by the manufacturer.

When converting from one gas type to a different type, the orifices supplied with the conversion kit must be checked for proper size as specified in this manual to assure that the oven is operating at the nominal rated input.
