Oil Burner
Burner Air Adjustment: The oil burner is preset for
operation at altitudes below 3000 feet. If operated at
higher altitudes, it may be necessary to adjust the air
band setting. Adjust the air band for a #1 or #2 smoke
spot on the Baccarat scale.
Hotsy Crossfire Oil Burner
Burner Air Adjustment: The oil burner on this
machine is preset for operation at altitudes below 500
feet. If operated at higher altitudes, it may be necessary
to adjust the air band for a #1 or #2 smoke spot on the
Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.

For higher altitudes, the air band opening may need to
be increased; for lower altitude, the .air band may need
to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the .air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location's environment as-
needed for best smoke spot and performance
compliant with local, state, and federal regulations.

Hotsy Crossfire Oil Burner
CAUTION: If white smoke appears from burner
exhaust vent during start-up or operation, discon-
tinue use and readjust air bands.
NOTE: If a flue is installed, have a professional
serviceman adjust your burner for a #1 or #2 smoke
spot on the Bacharach scale.
Gasoline Engine
This gasoline engine is preset for operation at altitudes
below 3000 feet above sea level. If operated at higher
altitudes, it may be necessary to install a high altitude
main jet in the carburetor. Contact an authorized engine
sales and service center for details.
Water Supply
This machine is designed to be connected to a pressur-
ized (20 to 100 PSI) water supply, capable of main-
taining a minimum of 6.0 GPM. If it is necessary to use
a gravity feed water tank, the following plumbing modi-
fications will be required.
A 1/2" NPT 3-way ball valve will need to be installed in
the water inlet line. Hotsy recommends the use of Watts
Regulator Valve #1/2 B6780 M1 (Hotsy P/N 921363)
for this application. With this valve in place this machine
will be capable of using both a pressurized or gravity
feed water supply without additional modifications. For
proper operation it is important that the valve be fully
open for its intended supply. This will prevent air from
being drawn into the system from the non active
source. Also the pressure supply must still be
connected to the float tank. The connection of a pres-
surized supply directly to the 3-way valve will prevent
detergent from being drawn into the system.
