Your friend doesn't have a furnace company do the annual maintenance on his

adjusting settings?

Please take out a life insurance policy on his family, and put me as the

....

my ?best friend throttled his back last winter, and had no troubles.

wouldnt recommend this for a direct vent 90+ type.

his furnace would occasionally gop boom on start up, throttled back it
didnt but ran longer.

he cleaned the burners this summer they were clogged near pilot light,
no more boom explosions

well he has multiple engineering degrees, and his best friend has a
PHD in mechanical engineering

interestingly he had a service company out who just said replace
furnace. while another friend a retired HVAC instructor said clean
burners

my buddy doesnt believe a new furnace will save him money. I replaced
our furnace by spring the proof will be in equitable gas bills

Incidently my buddy who cleaned his furnace converted both his
vehicles to compressed natural gas in the 70s and they still run on it
today.

not only did he design and build the system his machine shop and
foundry produced nearly all the parts.......

he is a retired teacher.....his effective price per gallon is about 2
bucks, natural gas has nerarly doiubled in cost in the last 2 years:

Ok, Hallerb, you ding dong. Listen up before you kill someone.
You, your ideas and your nutty Engineer crap is so full of holes it
isnt funny. This is a real simple checkout if you dont believe it.
A furnace is designed to operate within a certain range. Next time you
can, get your hands on a combustion efficiency analyzer. Put it in the
flue. On a 90% furnace just put it in the outlet pvc pipe. On a
standard furnace, just stick the probe in the metal flue. Now, start
cranking the gas pressure down and watch the CO reading (thats carbon
monoxide) go off the chart. Just for giggles, you can even turn the
gas pressure way up and get the same effect. In short, the burner was
designed to burn properly within a certain range. SO, if you are
truley bent on killing people, just keep popping off with your silly
EE ideas.

Oh really, there is a maximum stated temp the exchanger is designed
for and cutting gas to be within the range is normal to do. How is his
idea unsafe, how can he kill anyone, I guess down south yur ways you
exhaust into the basement because chimneys are too expensive. Running
at the low end of the exchangers temp is how I set mine up since my
hack pro was to lazy to check it. So are burners different on
Modulating gas valves, no, its just less gas. The idea has merit to
check what your temp is to be sure it is within the specified range,
and within the "range" is fine.
