fuel?
Action/Question/Component
Unknown/Cold/New Oil/Non Standard Mix -
Call EnergyLogic Technical Services group
for an Oil Analysis to be performed
4. When was the tank last drained of
water and other fall out materials?
Used Oil Storage Tanks should be drained
annually from the bottom most drain port
until only oil flows from the tank
5. When was the oil last analyzed?
EnergyLogic recommends that an oil
analysis be performed annually
6. Analysis Results (If EL does not
have the results, could we get them)
Consult EnergyLogic Technical Services
group for oil analysis interpretation
Inlet Water
1. Return Water Temperature?
EnergyLogic requires that return water to the
boiler system be a minimum of 140°F
Heat
Exchanger
1. Clean Heat Exchanger and Flue:
See Heat Exchanger Cleaning in
Section 8.5.1.
The entire boiler should be maintained and
cleaned according to the maintenance
schedule.
Pump/Filter
1. Check Fuel Pump Motor. Is the fuel
pump motor running while the burner is
running?
Yes - Go to Next
Action/Question/Component
No - See Metering Pump Assembly Testing
in Section 9.3
2. Check Fuel Pressure: Turn boiler on
or reset the red button of the primary
control. What is the fuel pressure
reading (gauge at pump outlet-PSI)
while burner is running?
0 or erratically fluctuating then Go to step 4.
If greater than 20 psi, see Nozzle/Solenoid
cleaning, or between 3 and 15 (normal) go to
next component check.
3. Fuel line check. Do the fuel lines
contact an exterior/cold wall?
Yes - If fuel line is in contact with an exterior
wall, this could result in extra load on the
pump. If fuel line is cold, add spacers (at
least .5 inches) to eliminate contact with the
exterior wall
No - Go to Next Action/Question
4. Check Fuel Vacuum: Turn boiler on
or reset the red button of the primary
control. What is the fuel vacuum
reading (gauge at pump inlet-inches Hg)
during the time the burner is running?
Zero or erratically fluctuating then Go to Next
Action/Question, or 1 to 10 In./Hg then Go to
Action/Question 6, or 10 in./Hg or higher (for
more vertical suction distance, allow more
vacuum) then Replace oil filter -see filter
replacement. If you are using a non-
EnergyLogic tank with strainer, inspect the
strainer for debris.
