Installations must follow these codes:

•Local, state, provincial, and national codes, laws, regulations and ordinances

•National Fuel Gas Code, ANSI Z223.1/NFPA 54 – latest edition (NFGC)

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

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 en- closed parking garages must be located at least 18 in. above the floor.

When such locations cannot be avoided, it is recom- mended that a suitable catch pan, adequately drained, be installed under the appliance. The pan must not re- strict 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.).
