R
Fuel Pump is producing the proper
pressure. In
order to determine if the
Fuel
Pump is producing the proper
pressure, reference Section 8.8 and
perform the Fuel Pump's "Fuel Pressure
Adjustment
Check".
D. Check and reset the Combustion Air
Blower gap, if applicable. In order to
determine
if the Combustion Air Blower's
gap
is set properly, reference Section 8.9
and perform Steps 1-6 and 11-17 of the
Bearings
"Replacement Procedure".
E. See the "NOTE" below.
NOTE: If the Hydro-Hot's exhaust system still
produces black smoke after performing all of
the listed checks, contact our Technical Depart-
ment
at 1-800-685-4298 for additional assis-
tance.

3. Pump the rubber ball - 18 times.
4. Release the suction hose from the
CO2 Analyzer's plunger.
5. Turn the CO2 Analyzer upside
down so that the fluid runs to the
top
and then turn it right side up
again. Perform this procedure
twice
.
6. Place the
CO2 Analyzer on a flat
surface and read the CO2 level.
7. The CO2 level should be between
10.5
and 11.5 percent (at a nomi-
nal 12 volts DC). If the
CO2 level is
not within specs, an adjustment of
the
Diesel-Burner's Combustion
Air Intake will be necessary,
reference the illustration on the
previous page. Once the proper
CO2 adjustment has been made,
be
sure to tighten the adjustment
screw.
NOTE: For temporary high altitude situations
(less
available oxygen) the
CO2 will rise by
0.3% CO2 per 1,000 feet of elevation. (e.g. a
Diesel-Burner adjusted at sea level should
register
approximately a 1.5% higher CO2
reading when in Denver, Colorado {5,000
above
sea level}). If permanently residing in a
high
altitude area, be sure to properly adjust
the Diesel-Burner
so that it operates within the
10.5% - 11.5% CO2 range.
NOTES: If the proper CO2 - value cannot be
ob
tained, perform each of the following inspec-
tions as necessary until the cause has been
detected:
A. Check the rubber Grommets on the top
and
bottom of the Diesel-Burner Head's
cast-aluminum Blower Casing to ensure
they are securely in place.
B. Check the Diesel-Burner Head for proper
alignment. (torque specification = approx.
20-40 in. lbs.), reference Section 8.2.
C. Check to ensure that the Diesel-Burner's
