.
-
INSTALLER MUST CHECK WITH LOCAL CODES REGARDING ACCEPTABLE METHOD OF DESIGNING
DUAL GAS PIPING SYSTEM TO PREVENT DIRECT FLOW OF FUEL FROM ONE SYSTEM OF GAS PIPING
INTO ANOTHER
(FOR EXAMPLE
, FROM NATURAL GAS TO PROPANE
, AND VICE VERSA
).

:
FITTINGS
, TO 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
.
