We're you able to figure out the issue with your furnace and generator?

I'm in NJ and was out of power from hurricane sandy for 5 days with a sick
1yr old.
I am looking to get a generator that will work with the same furnace that
you have
so I don't have to go through this again in the future if it ever happens
again. I'm
thinking of making a connection from whatever generator I get directly to
circuit breakers in the house with something like an interlock kit
(interlockkit.com) but I want to know that the furnace will run correctly
before I
make the investment.
My furnace is brand new Coleman Echelon 9.c.
I'm looking at either gas or propane generators.

Any advice is greatly appreciated!

Good thoughts, but natural gas sure is convenient if your gas system
survives your particular natural disaster.  The last four hurricanes
here haven't caused a bobble in our NG service.  After each hurricane, I
have had all the fuel I wanted without standing in one damn line!

So what happens if the natural gas system goes out?  Well I'm a bit of a
survivalist also!  That's why I have four 100# propane tanks and a
little trailer to take them for refilling should it ever become
necessary.  Turn off the NG valve, turn on the propane valve, and make
one quarter-turn mixture adjustment and I am back in business!

Still, I envy Neon John's buried tank.

Whatever you decide, think about your fuel supply and know how much fuel
your generator takes per hour.  Then do the math!  Figure both the cost
of running your generator through a long outage and how long you can run
with available fuel.  Then either have a realistic plan regarding where
your fuel will come from after a disaster, or have a sufficient supply
stored away.  Propane has the advantage that it never goes bad.  Diesel
stores longer than gas, but it still can have issues.

 My Brother, "The Engineer" is rebuilding his home in a mid-sized city in
Utah. He installed a 1K USG Propane Tank, underground in his yard, and
has NG piped into the house. He also has a 55 USG Drum of 80/87 Aviation
Fuel, sitting on steel stilts, and bolted to the floor and Garage Wall.
All this is to support his Generac 20Kw TriFuel Genset that lives in the
SECURE Generator Room, under part of the Double Garage ground level
Floor. Primary Fuel will be the NG Feed from the local NG Pipeline.
Should that fail then he can switch, the Genset, the Kitchen Stove, the
house H&AC, Hot Water Heater, and the Cloths Dryer, over to the Propane
Tank. The 80/87 AvGas is for the vehicles, and if in dire straights, can
feed the Genset.  The Genset can run the WHOLE House, or can be used to
charge an Outback 3648 Inverter with 2500 AmpHours of Battery that also
can run the whole House. The Inverter, Charge Controllers, & Batteries,
live in a Separate Electrical Room next to the Generator Room, under
another section of the Garage Floor. He has twin Outback MX-80 Charge
Controllers, that ties his 6Kw of Roof Mounted Solar Panels, to the
Battery Bank. Barring a Nuclear Air Strike in his valley, he is setup
for just about any eventuality. Just Say'en..... YMMV....

Your gas utility goes to to GREAT lengths to keep the gas from
failing.  If it does, it's an enormous economic hit to them.

I recall ~50 years ago the utility lost gas pressure to a
part of a suburb. They had to go to each house, shut off the
gas at the meter, then restart the gas in that neighborhood
and bleed. Then go to each house again, open, and light every
appliance. Repeat in neighborhood after neighborhood.
It took days.

When PG&E blew up San Bruno, parallel pipelines kept the
Peninsula and San Francisco going; in NTSB testimony PG&E said
restarting the city alone would have taken three+ months.

When max usage draws heavily on a system, the utility can add some
higher-Therm propane to the mix.

While gas transmission pipelines do have compressors, often they
are cannibals, burning some of the gas they ship. In any case,
the utility has local storage.

As I recall, much of NYC lacks natural gas distribution, but in
places where disasters have hit, the gas is often the utility that
keeps going.

Youngster. Ptfui. How's about when they switched over
from (so-called) "Town Gas" to natural gas. Same problem.
Had to shut down everyone and then reconfigure all
those burners...

Or... when the parts of the US that were transferred
and merged into the sixty cycle electric grid...

Only a small portion of NYC is natural gas deprived. There
are areas next to the ocean where buildings were badly
damamged enough that the utility shut off all fuel
to the neighborhood.

There are similar, and more widespread, issues where
lots of NJ and Long Island just Isn't There anymore.
