The temperature of the water in the hot water boiler can be regulated by setting the temperature dial on front of the thermostat. To comply with safety regula- tions the thermostat was set at its lowest setting before the hot water boiler was shipped from the factory. The illustration below shows the thermostat and how to adjust the water temperature.

To adjust the water temperature, insert a small straight screwdriver into slotted screw in hole in front of ther- mostat and turn wheel to desired setting.

CAUTION: Hotter water increases the risk of scalding! There is a hot water scald potential if the thermostat is set too high.

Equipment Base

The boiler should be mounted on a level, structurally sound surface. The boiler is approved for and can be installed 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 inches above the floor.

CAUTION: The boiler should be located in an area where water leakage will not result in damage to the area adjacent to the appliance 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.

In addition, the boiler shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, control replacement, etc.).
