The temperature of the water in the heater can be reg- ulated by using the temperature controller. To comply with safety regulations, the temperature controller is set at the lowest setting when shipped from the facto- ry.

To adjust the water temperature, insert a small straight screwdriver into the adjustment screw on the front of temperature controller and turn the wheel to the desired setting (See Fig. 4.).

Equipment Base

The heater should be mounted on a level, structurally sound surface. The heater is approved for installation on a combustible surface but must NEVER be installed on carpeting. Gas-fueled equipment installed in enclosed parking garages must be located at least 18 in. above the floor.

Stacking

Delta Limited units can be stacked two units high with an optional stacking rack. A stacking kit is available from Raypak for this type of installation.

CAUTION: The heaters should be located in an area where water leakage will not result in damage to the area adjacent to the appliances or to the structure. When such locations cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the appliance. The pan must not restrict air flow.
