1.0 INTRODUCTION
1.1 The Fyrite Pro
The Fyrite Pro series of instruments are hand-held analyzers 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 upgradeable 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
