INSTALLATION
a.
Disconnect fuel and power systems to the existing burner to be replaced, if any.
b.
Remove existing burner and set aside. Usually set-screws or bolts in the furnace flange
hold burner in place. Install Fire Tube using a split furnace flange. Make sure Fire Tube
extends all the way into the firebox in case the fuel drips. The Fire Tube should be set
essentially level so any liquid oil runs to the return line.
c.
All metal fuel tubing is to be connected with flare fitting as per fuel codes.
d.
Connect air pressure hose from compressor to Flame Control threaded end.
e.
Establish a gravity return fuel line, minimum 1/2” diameter, to original fuel storage
container. This requires bottom of Fire Tube to be higher than the maximum height of the
fuel in the storage container. This is critical to safe operation. If maximum oil-storage
level is above the Fire Tube invert height, return pumping is required. See our Product
Catalog for a
return
fuel pump
and contact Homestead Inc. for more installation details.
f.
Connect Compressor and Power Cabinet to a power source. Use a 15 amp maximum
dedicated circuit breaker.
g.
In a furnace operation, a thermostat for heat control must be attached to the Controller “T”
terminals for the unit to operate. For testing purposes, a jumper-wire between these
terminals will allow unit to operate. Set dead-band on thermostat to a close control so the
burner operates more frequently.
START-UP
a.
Yellow Heat will burn up to 100% unfiltered yellow grease or other medium weight oils.
All fuel should be processed through our
Fuel Storage System
.
b.
We recommend initial installation be conducted with standard heating oil or other light oil
before attempting to burn 100% vegetable oil. Learn the operating characteristics of the
Yellow Heat Burner before transitioning to a vegetable oil fuel.
c.
For easiest operation, fuel should be at least room temperature (greater than 50°
F
). Cold
startup can be accomplished with the Fuel Enhancement Procedure. Congealed oils will
require additional heating prior to use.
d.
First ignition of yellow grease may be slow to start if the fuel is cold and/or wet. Yellow
Heat Burner has a starting procedure that uses a more volatile fuel to help establish normal
operating conditions. Add 10% of the volume of the Fuel Storage Tank in standard
heating oil on top of any existing vegetable oil fuel in the tank. Experience in blending
various fuels, care in dewatering some yellow grease, keeping the fuel storage tank warm,
and general system maintenance will diminish any need for special start-up procedures.
