INSTALLATION AND OPERATION GUIDELINES
WARNING
ONLY Authorized Technicians strictly complying with Homestead Inc.’s instructions and
national, state and local or other applicable codes should perform installation,
maintenance and service on the unit’s components. Installation and use of this used oil-
burning appliance shall be in accordance with the standard for the Installation of Oil
Burning Equipment ANSI/NFPA 31, 1987, and National Electric Code, ANSI/NFPA 70,
1990 and the requirements of the inspection authorities having jurisdiction.
a.
The Yellow Heat Burner may be installed as part of a complete heating system using the
Yellow Heat Furnace, or it may be installed in some types of existing liquid-fuel fired
boilers and furnaces as a retrofit. Yellow Heat Burner will operate correctly in most
existing waste oil furnaces with little or no modifications required. This will add the
capability to burn up to 100% yellow grease to an existing waste oil furnace. For other
types of existing oil-fired equipment, several considerations are recommended before a
retrofit application is attempted.
b.
The return-oil line requires the Yellow Heat Burner to be elevated above the level of the
fuel in the oil storage tank. If this is not practical, a
Return Fuel Pump
may be installed.
Contact Homestead Inc. for details.
c.
The firebox of an existing furnace or boiler should be large enough to accommodate the
larger size of a vegetable oil fired flame, which is up to twice the size of a petroleum-oil
fired flame. Too small a firebox may lead to the premature burn-out of the heat exchanger
or other problems.
d.
A high-temperature glass window or view-port in any heating appliance is recommended
so the size and characteristics of the flame can be observed for proper tuning purposes.
The Yellow Heat Furnace is equipped with a removable glass window.
e.
Gravity return-oil line to be 1/2” minimum diameter metal pipe. Pumped return-oil lines
are not length limited.
f.
Do not fill the
Fuel Storage Container
more than 7/8 full of vegetable oil fuel. Because of
the possible addition of starting fuel to this container in the start-up mode, it is necessary
to have some free storage capacity for returned fuel so that the storage container does not
become over-filled.
g.
Maintain fuel level in storage container between 7/8 full and
¼
full, according to the fuel
level indicator. Using fuel below the
¼
cutoff may result in entrained water being uptaken
and performance deterioration.
