I am on Eastern Long Island, directly in one of the projected paths of =
Hurricane Henri.  We are being told to plan for 7-10 days without power, =
although FWIW we were only powerless for 4 days following Sandy.  =
Shortly after Sandy I purchased an LP Generator =
(https://www.jbtools.com/buffalo-tools-gen4000lp-4000-watt-propane-generat=
or/?wi=3Doff&gclid=3DCjwKCAjwyIKJBhBPEiwAu7zll1U54VH4euJneVO0jmOzjdgwy6-t0=
MUdEtaEHYXf_7W0sQxKo54TphoC__4QAvD_BwE) which, of course, I have never =
needed, although I do run it periodically to be safe.  It is designed to =
run off of LP tanks and comes with a standard regulator.  A little =
Googling shows the following specs for the regulator:

Low Pressure Regulator
Inlet Pressure:               25-250PSIG
Outlet Pressure:            280mmH2O=3D (11"W.C.)
Flow Capacity(MAX):    119000(BTU/hr)

We use Propane for DHW and heat and have a 500 gallon in-ground tank.   =
I had an outside gas line stubbed out when the house was remodeled, just =
in case I ever needed it and I would like to be able to connect the =
generator directly to the house supply and avoid having to depend on the =
portable tanks.  The house supply is regulated and, as an example, here =
are the specs for the water heater:

Max Inlet Gas Pressure:    13.0 =E2=80=9CW.C.
Min Inlet Gas Pressure:     8.0 =E2=80=9CW.C.
Recovery Rating:               206/Gallons/HR
Max Working Pressure:     150psi
Max Output:                       180,000 BTU/HR
Max Input:                          11,000 BTU/HR
Manifold Pressure:             3.9 =E2=80=9CW.C. (For Max Input)

Am I missing anything, or should I be able to hook the generator =
directly to the house supply without the regulator?  For the record, I =
tried it once with the regulator attached and it barely ran and didn=E2=80=
=99t put out any appreciable power.  I always meant to research this =
before I needed it, but like many of us, never got around to it until =
now.

Thanks,
Jim
