IMPORTANT SAFETY INFORMATION
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
These machines are designed for indoor use.
They must be stored indoors when not in use.
Location:
The location should protect the machine from dam-
aging environmental conditions, such as wind, rain,
and freezing temperatures.
The machine should be run on a level surface where
it is not readily influenced by outside sources such
as strong winds, freezing temperatures, rain, etc.
The machine should be located to allow accessibil-
ity for refilling of fuel, adjustments and maintenance.
Normal precautions should be taken by the opera-
tor of the machine to prevent excess moisture from
reaching the power unit or electrical controls.
It is recommended that a partition be made between
the wash area and the machine to prevent direct wa-
ter spray from coming in contact with the machine.
Excess moisture reaching any electrical components
or controls will reduce machine life and may cause
electrical shorts.
During installation of the machine, beware of poorly
ventilated locations or areas where exhaust fans
may cause an insufficient supply of oxygen. Suffi-
cient 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 bringing the air into the machine.
WARNING: Avoid small areas or areas near exhaust
fans.
INSTALLATION
Electrical
The machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter. The
HOT 2-1100, HOT 2-1500, and HOT 3-1100 each
require a 120V-20 amp receptacle to comply to the
UL 1776 Standard.
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 should be adequate.)
Water Source
Water source for machine should be supplied by a
5/8" I.D. garden hose with a city water pressure
of not less than 30 psi. If the water supply is inad-
equate, or if the garden hose is kinked, the machine
will run very rough and the burner will not fire.
Connection
Connect the wand, nozzle, hose and spray gun,
where applicable (see Component Identification).
On pipe thread connections, use teflon tape to
avoid water leaks.
Venting
Adding exhaust vent pipe to your oil fired burner is
not recommended. The pipe restricts air flow which
causes carbon buildup, which affects the operation,
and increases maintenance on the coil. If a stack
must be used, refrain from using 90° bends. If the
pipe cannot go straight up then use only 45° bends
and go to the next larger size pipe. The overall pipe
length must not exceed 6 feet. The addition of a vent
pipe will require an air adjustment and smoke test.
