For Indoor and Outdoor Uses

Placement of the Machine:
Where it will NOT be exposed to rain, snow, or

direct sunlight. Exposure to water can cause
electric shock.
Where no flammable vapors, dusts, and gases

are present.
At least 7 feet away from combustible materials

(when burner used).
Away from all building windows and air intakes

(when burner used).
Away from other heat-generating equipment.

Positioning:
Situate the machine on a firm, level, heat-

resistant surface with good drainage.
Block wheels to prevent movement.

Airflow:
Provide for adequate, unobstructed airflow for

cooling and combustion air.
Do not allow debris to accumulate or block

airflow.
Do not operate with a tarp, blanket, or cover

surrounding the machine.
Do not place any objects against or on top of the

unit.
Electrical Precautions:
To reduce the risk of electrocution, keep all cord

connections dry and off the ground.
Do not touch plug with wet hands.

Step 4. Oil Burner Adjustment

Burner Air Adjustment: The oil burner is preset and
performance tested at the factory (elevation 1100 feet).
A one-time initial correction of the burner for your
location will pay off in economy, performance, and
extended service life.

1.) Turn the pump and heat switches on (Refer to
"Operation" for details). Have someone operate the
spray gun so the burner fires.
2.) Loosen the locking screw and close the air band
until black smoke appears from the burner exhaust
vent. Note the position of the white arrow on the air
band.
3.) Slowly open the air band until white smoke just
starts to appear.
4.) Turn the air band half way back to the black smoke
position previously noted. Tighten the locking
screw.
5.) Fine tune the burner air by loosening the shutter
lock screw and turning the shutter until the exhaust
is cleanest. Tighten the shutter lock screw.

CAUTION: If white smoke appears from the burner
exhaust vent during start-up or operation,
discontinue 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.

Step 5. Verify Electrical Connection

Grounding

Product must be grounded. The supply cord is equipped
with an equipment-grounding conductor and a
grounding plug. This plug must be plugged into an outlet
that is properly installed and grounded in accordance
with all local codes and ordinances.

Ground Fault Circuit Interrupter Protection

Connecting the water heater through some type of
ground fault circuit interrupter (GFCI) protector is
required to comply with the National Electric Code
(NFPA 70) and to provide additional protection from the
risk of electric shock.
