1.0 INTRODUCTION
1.1 The Fyrite Pro
The Fyrite Pro series of instruments are hand-held an a lyz ers that are
designed for on-demand sampling of residential furnaces and appliances.
The more advanced models can also to used to check combustion efficiency
by measuring the stack temperature and the percent oxygen level in the
flue-gas stream.
The Fyrite Pro is completely upgradable from the very simple Model 100
that measures only carbon monoxide, to the Model 125 that measures
carbon monoxide (CO), oxygen (O
2
), draft, differential pressure, ambient
air temperature, stack temperature, and combustion air temperature, as
well as calculating combustion efficiency, excess air, carbon dioxide (CO
2
),
differential temperature, and CO air free.
This manual contains information on all models of the Fyrite Pro. Please
disregard any information that does not pertain to your model.
WARNINGS!
This analyzer should not be used on a continuous basis.
This analyzer does not have an audible alarm, and should
not be used as a safety device.
Except for battery replacement, this analyzer should only be
opened and ser viced by au tho rized personnel.
When testing an appliance, a full visual in spec tion of the
appliance should be carried out to ensure its safe op er a tion.
CAUTION!
When the instrument is used in an inef
fi
cient furnace or
boiler application where there is a high emission of soot,
probe sample
fi
lter may become clogged. Check
fi
lter before
every use to con
fi
rm that it is clean for use or replace with
a new
fi
lter. To prevent this from occurring, a smoke test
should be performed before operating under such conditions
to ensure that the furnace is burning at a level appropriate
for the use of this instrument.
