INSTALLATION
Place machine in a convenient location providing ample
support, draining and room for maintenance.
This machine is intended for indoor use. Machine
must be stored indoors when not in use.
Location:
The location should protect the machine from damag-
ing 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 temperatures, rain, etc.
It should be located to allow accessibility 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. Ex-
cess 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.
