Thanks I didn't mean to run 2-3 days without refueling I meant the longest
outage I've seen is that and prepare for that. The online guides I saw
seemed to be geared toward bigger switch over units. I planned on making an
extension cord with male on both ends and back feeding the system but as you
pointed out doing this at 220 would make more sense as I don't have to make
sure or put everything I want to power on one leg of the 110, 220 would do
this for me.

5K or more it is then and I think I'll run that 220 line to the garage after
all and back feed with the main off to the whole house. I have all my
expensive electronic devices on UPS's already so they should be OK with the
transition I just have to see how it all works when needed.

Thanks for the help, Rich

Was planning on it. Before you get upset, look at the critical pats of the
construction this time.

Open window, open door, roof vents and an open air fan plus garage door open
at least 6 inches (more if rain allows.)

Read the conditions first please. This isnt an enclosed airtight garage.
In fact, it is designed that way because of the gas furnace unit.

Once the rain passes, it can go on the back screened porch.

If it helps, we had a free estimate done for an installed unit and asked
about this. The installed unit was more than we wanted to pay (about
1,500$). With the back door to the porch open (shielded from the rain) and
the side window, major draft. Opening the garage door 6 inches up,
windstorm in there.

Yup that's the way people do it ... and still die

Do you have CO detectors around the house?

A few years ago, our condo maint. people were operating a generator in
the open-air atrium of our
building. Atrium is open on four sides, with roof over it. Our AC is
at the opposite end of the building from where they worked. We had an old
CO detector, no longer used because we have no gas appliances, in a box
in the laundry room. There
was enough CO given off outside to set off our alarm inside.

I recall reading about one death in Florida because the setting
described resembled a friend's home.
Had a generator going in their screened-in outdoor room. They woke up
dead. :o)

CO is a bit heavier than air. If the atrium was only open at the top
the result was to be expected.
