LOCATION

CAUTION: Do not locate the steamer over an open drain. Steam and moisture vapors could damage the steamer and may not be covered under warranty.

The installation location must be kept free and clear of combustibles. Do not obstruct the flow of combustion and ventilation air. Minimum clearances from noncumbustible and combustible construction are 0" on the right side, 0" on the left side and 6" (15 cm) at the rear for proper air circulation. Install the steamer on a noncumbustible floor. Provide adequate clearances for cleaning, maintenance, service and proper operation.

Allow 18" (45.7 cm) between any other piece of equipment or a wall for service access. Service for the controls for the steamer compartments requires access to the upper right side panel.

Allow sufficient air to enter the room to compensate for the amount of air removed by any ventilating system and for combustion of the gas burners. Do not obstruct the air flow into and around the appliance. Do not obstruct the flow of flue gases from the flue duct(s) located at the rear and above the steamer. Position the steamer in its final location. Check that there are sufficient clearances to service the controls, for doors to swing and to allow the required supply and drain connections.

VENT HOOD

Install an exhaust system directly above the steamer to vent steam and combustion gases generated by the steamer and gas boilers. Refer to NFPA Standard #96,
