:
- INSTALL APPROPRIATE REGULATOR FOR CURRENT FUEL IN USE
.
- 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
).
