The temperature of the water in the heater can be reg- ulated by using the optional temperature control. To comply with safety regulations, the optional tempera- ture control will be set at the lowest setting when shipped from the factory.

To adjust the water temperature, insert a small straight screwdriver into the adjustment screw on the front of temperature control and turn the wheel to the desired setting (See Fig. 6).

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

INSTALLATION

Installation Codes

Installations must follow these codes:

·Local, state, provincial, and national codes, laws, regulations and ordinances.

·National Fuel Gas Code, ANSI Z223.1- latest edi- tion (NFGC).

·National Electrical Code, ANSI/NFPA 70 - latest edition (NEC).

·Standard for Controls and Safety Devices for Automatically Fired Heaters, ANSI/ASME CSD-1, when required (CSD-1).

·For Canada only: CAN/CGA B149 Installation Code (B149) and C.S.A. C22. 1 C.E.C. Part 1 (C22. 1).

Equipment Base

The heater should be mounted on a level, structurally sound surface. The heater is approved for installation on a combusti ble 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.

CAUTION: The heater 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 heater shall be installed such that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation or service (circulator replacement, control replacement, etc.).

WARNING: This product must be installed by a licensed plumber or gas fitter when installed within the Commonweatlh of Massachusetts.
