Connection to outdoor gas piping must be done by a certified plumber.

Installation must be made in accordance with any local codes or regulations, or in the absence of
local codes or regulations, in accordance with the National Fuel Gas Code (NFPA 54/ANSI Z223.1).

The hose and fittings should be visually inspected periodically to determine that they have not


The hose and fittings are designed for movement after installation, but must not be kinked, twisted
or torqued.

Protect hose and fittings from dust, dirt, and damage when not in use. Insert plastic plug in the
socket and the cap over the hose end plug whenever the hose is removed from socket.

If your home has no outside Natural Gas (NG) piping, a connection must be installed by a certified

Only use the provided quick connect adapter with provided hose assembly.


•
Remember that whichever fuel delivery system or type of vapor fuel used, the fuel pressure at the
demand regulator installed on the engine generator must be between 0.25 and 0.40 PSI. (7-11
inches of water column or 4 and 6 oz. of water column). Any lower pressure and the unit will starve
for fuel under load. If the hose and quick connect adapter are properly connected and still not
getting gas, delivery pressure needs to be verified. For pressure greater than 0.5 PSI, make sure
that an in-line regulator is present. This additional regulator is NOT provided with this kit. Another
concern would be rating if hose and quick connect adapter. Both the hose and the quick connect
adapter are only rated to 0.5 PSI.
