INSTALLATION
Place machine in a convenient location providing
am ple 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 -
ag ing environmental conditions, such as wind, rain,
and freez ing temperatures.
The machine should be run on a level surface where
it is not readily infl uenced by outside sources such
as strong winds, freezing temperatures, rain, etc.
The machine should be located to allow accessibil-
ity for re fi ll ing of fuel, adjustments and maintenance.
Nor mal pre cau tions should be taken by the opera-
tor of the machine to pre vent excess moisture from
reach ing the power unit or electrical controls.
It is recommended that a partition be made be tween
the wash area and the machine to pre vent direct wa -
ter spray from coming in contact with the machine.
Ex cess mois ture reaching any electrical components
or controls will re duce machine life and may cause
elec tri cal shorts.
During installation of the machine, beware of poorly
ven ti lat ed locations or areas where exhaust fans
may cause an insuffi cient supply of oxygen. Suffi -
cient com bus tion can only be obtained when there is
a suf fi
cient supply of oxygen available for the amount
of fuel be ing burned. If it is necessary to install a
ma chine in a poor ly ventilated area, outside fresh
air may have to be piped to the burn er and a fan
in stalled bringing the air into the machine.
WARNING: Avoid small areas or areas near exhaust
fans.
Electrical
The machine, when installed, must be electrically
ground ed in accordance to local codes. Check for
prop er power sup ply using a volt meter. The
HOT 2-1100, HOT 2-1500, and HOT 3-1100 each
require a 115V-20 amp re cep ta cle to com ply to the
UL 1776 Standard.
Placement
Do not locate near any combustible material.
Keep all fl am ma ble material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from fl oor
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 fi re.
Connection
Connect the wand, nozzle, hose and spray gun,
where applicable (see Component Identifi cation).
On pipe thread connections, use tefl on tape to
avoid water leaks.
Venting
Adding exhaust vent pipe to your oil fi red burner is
not recommended. The pipe restricts air fl ow which
caus es car bon buildup, which affects the operation,
and in creas es main te nance 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 larg er 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.
IMPORTANT SAFETY INFORMATION
Follow the maintenance instructions
specifi ed in the manual.
