1. IMPORTANT –
Prior to starting the unit, pre-fill the filter and fuel line with oil to assist priming
procedure. Oil pump motor turns at low RPM’s and would take significant time to complete
priming process if not pre-filled. Make sure the oil supply line fittings are air tight. Vacuum
leaks are notoriously hard to find. Pressurizing the line with oil in it can help to locate leaks.
2. Proper draft. Draft is the gases traveling through the heater and out the stack or flue. If
exhaust fans are present in your building, chances are a draft inducer will be needed. Call
our factory or see our website for help, www.econoheat.com
3. During the initial power up process the burner is locked out from energizing until the oil has
been properly pre-heated to operating thermo set-point, approx 3 to 5 minute duration.
Once the oil has been pre-heated, power is then applied to burner components and oil
pump.
4. Making sure the thermostat is turned off, apply power to the burner. Switch burner main
power switch to ON position. After allowing the oil pre-heater time to establish temperature
set-point, approximately 5 minutes. Jump the “T” terminals on the Oil Primary Control (figure
3). Once the burner is running, temporarily jump the “F” terminals on the Oil Primary. This
will allow the burner to run during the pump priming process.
5. Priming the oil pump: Open bleeder valve one turn until all air is expelled (figure 6). This
may need to be done twice to insure all air is removed. IMPORTANT: When fully purged and
flame is established remove temporarily jumpers on “F” terminals of the Oil Primary to allow
safety features of the unit to operate properly.
6. Adjust air supply of integrated air compressor to 12–13 P.S.I. This is factory preset, however,
due to freight handling settings may be compromised.
7. Combustion air band (figure 3) should be open approximately 1/2” or until flame is clear
yellow, not orange. Opening the air band too far may cause delayed in starting or even
prevent the flame from starting.
Inspect flame length through inspection door located above burner gun assembly. End
of flame should reach
no further than ½ way down combustion tube.
To accomplish this
flame length, use adjustment knob on opposite side of oil pump.
NEVER ATTEMPT TO START
HEATER WHEN COMBUSTION CHAMBER IS HOT AND A DELAYED START.
Waste Oil Burner Start-up Procedure
Water Treatment
Generally no water treatment will be required. Care should be taken to ensure that the system
does not lose water from leaks, or continual relief valve operation since continual make-up
water will reduce boiler life.
