CO deaths are a result of poor combustion adjustment combined with flue

1) People believing that a gas furnace does not require annual
inspections / service. This creates a greater probability of the furnace
falling into disrepair and the poor adjustment and leakage forming.

And the average Oil burner in a home that is not serviced properly is
JUST as dangerous.

That has been my point when people keep claiming that gas burners don't
need service. The fact is that any combustion appliance is dangerous if
it's not serviced properly.

Who was claiming that gas burners don't need service, let alone "keeps
claiming" that?

Someone in this thread.

Who?







No disrespect intended, Pete.

This whole thread seams to be diminishing the attention due to oil
burning equipment.

A delayed ignition that has not left the confines of the combustion
chamber may not be an explosion according to some, however it is an
unplanned event.

It also rarely occurs without human intervention not heeding the
warnings on the unit. New units take the human factor into account as
well with lockout modes.


What you learn in a classroom is fine. It prepares you to go into the
field. Once you've been in the field for 3-4 years, you realize just
how little you knew that first year.

Many things go wrong with oil burners. YOU may know to stop resetting
your protectorelay after the third time, however most DO look at it
like an elevator button.

Right, but that is not the fault of the oil burner and newer oil burners
prevent that as well.


Most are filthy. Just have a fly on the wall look-see at most HVAC
shops and watch the service techs try to casually avoid the oil
service calls.

Because most do not get their annual service. No annual service for a
few years and nozzles begin to clog causing the combustion to go out of
adjustment, soot to form and efficiency to plummet until finally someone
calls for service. If they were serviced even every other year they
would be nice and clean.

Same with a natural gas furnace. Of course I'd rather have a nat gas furnace
that hasn't been serviced in years than an oil furnace.

Oddly enough I'd rather have a furnace that has received proper
servicing.





Oh, by the way, standing in front of a 750 HP boiler (30,131,000
btu's per hour./ 215 gal. per hour) while it huffs itself out for .5
seconds, and then back into high fire with out shutting off the main
fuel valve will forever makeup ones mind on weather or not an oil
burner can or cannot explode.

Yea, large commercial / industrial boilers of either gas or oil can do
interesting things. Recall one story of a fairly small nat. gas
commercial boiler on about the 20th floor of a building that had it's
own little blowback and blew the boiler door off barely missing the
service guys before it went through the wall and fell the 20 stories to
the street below.

Blowback? Who puts a boiler on the 20th floor? (I could understand a
furnace).

Blowback, delayed ignition, whatever you want to call it. A gas buildup
in the combustion chamber prior to ignition. Boilers are commonly
located on upper floors in tall buildings. Furnaces tend not to be used
in large (tall) commercial buildings in favor of larger boilers serving
multiple heat exchanger air handlers.
