you can use the instrument by placing a
rubber hose over the probe and extending that into the chamber area with that
stainless tubing.
Overfire testing is why although my
analyzer is always on the job, my trusty
Fyrite (Figure 5), is always in working
condition and never far away. If you're
not sure of the condition and accuracy
of your old chemical (wet-kit) check
out Firedragon Field Note #5 on my
website.
Finally, another pet gripe of mine.
See that adjustable cone in Figure 4?
That's used to center the end of the
probe in the fluepipe. If you don't cenFigure 5
ter the probe you don't get the most
accurate readings, and that goes for the clip on thermometers
(Figure 6), too. On that note I still see and hear a lot about condensing flue pipes and chimney damage, too many. If you read
my articles regularly you know that I feel 400°F should be the
minimum Gross stack temperature on any conventionally fired
Figure 6
appliance regardless of fuel used.
Many of the mistakes I see are from
inaccurate readings so and those
readings come from inaccurate and
misused test equipment…when
you get a chance read Note #5. By
the way I don't blame someone for
doing it wrong if he/she doesn't
know, I blame who taught them.
We took a big chunk of this
article out of my book 'Advanced
Residential Oilburners' and if you
don't own it maybe you should?
