Operations
Installation
Place machine in a convenient location providing
ample support, draining and room for maintenance.
This machine is intended for outdoor use. Machine
must be stored indoors when not in use.
Location:
The location should protect the machine from
damaging environmental conditions, such as wind, rain,
and freezing.
1. This machine should be run on a level surface
where it is not readily influenced by outside
sources such as strong winds, freezing tempera
-
tures, rain, etc. It should be located to allow acces
-
sibility for refilling of fuel, adjustments and
maintenance. Normal precautions should be taken
by the operator of the machine to prevent moisture
from reaching the electrical controls.
2. It is recommended that a partition be made
between the wash area and the machine to
prevent water spray from coming in contact with
the machine. Excess moisture reaching any
electric components or electrical controls will
reduce machine life and may cause electrical
shorts.
3. During installation of the machine, beware of
poorly ventilated locations or areas where exhaust
fans may cause an insufficient supply of oxygen.
Sufficient combustion can only be obtained when
there is a sufficient supply of oxygen available for
the amount of fuel being burned. If it is necessary
to install a machine in a poorly ventilated area,
outside fresh air may have to be piped to the
burner and a fan installed to bring air into the
machine.
Avoid small locations or areas near exhaust fans.
Electrical:
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter.
Placement:
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away from walls should be adequate.)
Water Source:
The water source for the pressure washer should be
supplied by a minimum 5/8" I.D. garden hose with a city
water pressure of not less than 30 PSI. If the water
supply is inadequate, or if the garden hose is kinked,
the attached pressure washer will run very rough and
the burner will not fire.
Connection:
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon
tape to avoid water leaks. (See Component Identifica
-
tion).
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes
carbon build-up, which affects the operation, and
increases maintenance on the coil. If a stack must be
used, refrain from using 90° bends. If the pipe can not
go straight up then use only 45° bends and go to the
next size pipe. The overall pipe length must not exceed
6 feet in length*.
NOTE: After vent pipe installation test burner using a
smoke tester and adjust air setting to achieve a #3 or
below results.
