Flame Monitoring Cad Cell:
A qualified service technician may check the cad cell [Flame on]
Disconnect the cad cell leads from the FF terminals on the controller.
Using TT and FF jumpers, run the boiler.
Measure the resistance (ohms) of the cad cell by probing across the cad cell lead wires.
An acceptable resistance is 0 to 500 ohms for a clean burner and heat exchanger with
the flame on.
Remove the TT jumper to turn off the burner. The resistance reading with no flame
should be greater than 5000 ohms. Your meter may register “OL” if out of limit.
Make sure all jumpers have been removed when testing is complete.
7.5 Everyday Operation of Your EnergyLogic Used Oil Boiler
Once installed and checked, operate your EnergyLogic Boiler as follows:
Daily Operation.
Set the controls to the desired temperature settings.
You should not let the temperature of the room get below 50°F (10°C), or the oil will
become very thick, which may cause fuel delivery issues.
To shut down the boiler in an emergency, turn off the power at the user-installed,
switched junction box or main breaker.
Manage the Used Oil.
Do not put unapproved substances into your used oil storage tank. See section 1.5.1 for
a list of approved fuels.
Monitor the bottom of your tank for water and drain it off on a regular basis.
Don’t let your oil tank run dry. Don’t risk introduction of air into the fuel delivery system.
You will save yourself much time and trouble by keeping your tank filled with oil. If you
don’t have one, consider installing an optional EnergyLogic Low-Fuel Cut-Off Switch to
turn off the burner at low fuel levels.
When filling the tank be careful not to agitate the oil so that air/sludge are not introduced
into the fuel pump. It is best to leave the boiler off while filling the tank.
Pre-screen the oil prior to putting it into the tank. Occasionally have your tank drained
and cleaned.
Monitor the System.
After your initial set up, monitor the system gauge readings on a regular schedule to
assure that the system is stable. Record the readings and any maintenance performed
in the maintenance log (refer to section 8) to track your system performance over time.
Maintain your boiler. Regular maintenance will help to keep the boiler running reliable
and efficient for many years.
Summer Blower Operation and Shutdown
Perform seasonal maintenance.
Unplug the burner if the boiler is not going to be used for an extended period of time.
Refer to shutdown procedure in Section 8.6.
