NOTE (7.6-D):
In order to determine if the

is adjusted
properly, a CO Gas-Analyzer will be required;
reference “Illustration 7.6-3.” Also, reference
Section 11 for the Bacharach Fyrite CO Analyzer’s
part number information, if necessary.
I.
When using the Bacharach Fyrite CO
Analyzer, turn the
“Diesel”
switch
ON
and
allow the
Diesel-Burner
to ignite and operate
for approximately 2 minutes. Then
perform the following procedures:
1. Place the small end of the CO
Analyzer’s suction hose into
the Aqua-Hot’s
Exhaust Pipe
.
2. Place the round plunger
connection of the suction hose
on the CO Analyzer’s
“Plunger.” Press down on the
suction hose with the palm of
your hand until the CO
Analyzer’s “Plunger” is fully
compressed. This will allow a
sample of the Aqua-Hot’s
exhaust to enter the CO
Analyzer; reference
“Illustration 7.6-3.”
