Do not place any type of insulating material in the required clearance spaces surrounding the oven. There must

be adequate clearance between the oven and combustible materials. Clearance must also be provided for

servicing, cleaning and for operating the oven.

WARNING
Do not obstruct the flow of combustion and ventilation air to and from your oven. There must be no
obstructions on, under or around the oven. Constructional changes to the area where the oven is
installed must not affect the air supply to the oven. Do not pack required air spaces with insulation or
any other material.

The appliance and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing of that system at test pressures in excess of ½ psi. The appliance must be
isolated from the gas supply piping system by closing the individual manual shutoff valve during any
pressure testing of the gas supply system at test pressures equal to or less than ½ psi.
