(FOR DUAL-FUEL INSTALLATION, SEE NOTE 9)
DUAL GAS PIPING SYSTEM TO PREVENT DIRECT FLOW OF FUEL FROM ONE SYSTEM OF GAS PIPING
- INSTALL APPROPRIATE REGULATOR FOR CURRENT FUEL IN USE.
- INSTALLER MUST CHECK WITH LOCAL CODES REGARDING ACCEPTABLE METHOD OF DESIGNING
INTO ANOTHER (FOR EXAMPLE, FROM NATURAL GAS TO PROPANE, AND VICE VERSA).
9) FOR DUAL-FUEL INSTALLATION:
PREVENT INTERFERENCE WITH REMOVAL OF HEATER PANELS. WHEN A FLEX CONNECTOR IS FACTORY SUPPLIED
BY AERCO, IT MUST BE INSTALLED AT THE HOT WATER OUTLET CONNECTION OF THE WATER HEATER.
ALL PIPING & ELECTRIC CONNECTIONS (SERVICE SWITCHES, CONDUIT BOXES) SHOULD BE 6" AWAY FROM SIDE PANELS.
LOCATE GAS PRESSURE REGULATOR A MINIMUM OF 2' FROM HEATER.
