SoundGuy,
It might run the furnace for 30 minutes (Honda does a 10% overload for 30 minutes), but it would be pushing things VERY hard.

So I had a chance to measure my house furnace with my Kill-a-Watt meter and with the burner going & fan running on 120 vac house power got the following readings -
PF 0.61
VA 751
Watts 460
Amps 6.0
The little Yamaha EF1000iS is peak rated @ 1000 watts, continuous rated @ 900 watts, and 900 VA when the load PF is 1.0 ... but with the furnace having a PF of 0.61 the best the genset could provide would be 549 VA. Hmmmm, that's not gonna work if the furnace requires 751 VA. Nuts. :(
