Hi Sue;
 
Yes, the dealer found spaces in the seals between the furnace & the outside,
so it was sucking in outside air..  Finally got the hot water heater fixed
after 3 weeks of waiting and 2 days of them working on it.
 
I also got a CO detector with a number read out on it for $29 from Target.
It's a "Nighthawk" brand.  The ones without a # display trigger at 100ppm,
but the EPA set the limit for 8 hour exposure at 50ppm!  So the most popular
sellers can let you get sick & not warn you that something is not right!
 
Take care, Gary
