Help with Em-100 boiler

I just filled up my oil tank (it was empty) and cannot get the boiler running. Boiler is Emarald EM-100 by Cloumbia. The oil company said to open the nipple valve to bleed the air out of the incoming oil line. They said to leave this open untill a staedy stream of oil comes out, then close the valve and restart the system. I have the valve open, and it is dripping about 1 drop every 3 seconds. How long will this take? Is there anything else I should check?

 

Since the tank was empty there is a chance that the sludge in the bottom was disturbed & either the filter or the screen is clogged. Change the filter & clean the screen.

 

You may have sucked some sludge as Pulpo suggests, but you can't bleed the pump without it running... it sounds as though that's what you are doing.

Put a wrench on the bleeder fitting and a container to catch the oil that will come SPEWING out of the bleeder. You should also have a piece of clear hose on the bleeder that fits snugly and down into the container. The oil will come out with some force, so be prepared for this! It might be a good idea to put a layer of newspapers around on the floor. You don't want any surprises...

Have a helper fire the boiler by turning up the thermostat, and while the burner is running, open the bleeder and allow the oil to flow into the container until you see no more bubbles.

Close the bleeder and the burner should fire right up as soon as you close the bleeder.

You will probably 'time out' the primary control and the button will pop up while you are bleeding. If this happens, push the reset button and continue.

You might need to do this several times, as you pulled all the oil out of the lines.

Does your fuel pump have ONE line or TWO ?

 

I replaced the filter and cleaned the filter housing and the line between the filter and the ignitor. There is still not a steady stream of oil coming from the bleeder valve. I have the system running to help pull the oil through.
Also, the blinking green light on the module shows it in Lockout mode. Pushing the button does nothing. Does the system have a preset delay time before it ignites, or does it need a certain pressure from the incoming line? How long can this take to bleed the air out? Is there that much air trapped inside the ignitor area, or might there be another problem with it?

 

There is another screen that could be clogged in the housing where the bleeder screw is. Did you clean it?

I couldn't find anything on lockout mode. Reset the breaker.

 

If the oil tank is at the same level or above the burner, oil should pour out of the bleeder without running the pump. It will take a little time for it to fill the filter then the line. But once it hits the pump it will be pouring out.

In the case that it doesn't check to make sure that the valve at the tank is open (needed to be closed to change the filter). If still no oil then most likely need to blow the line out.

Only a few psi is all that is required.

Al.

 

I just checked the screen on the housing. It had a little sludge but not much. I cleaned it off, reassembled everything, and turned it on. Still have blinking green light. The motor for the water line is running, and I can hear the water circulating, but the burner is still not doing anything. I've tried resetting the main circuit, as well as adjusting the thermostats.

 

Your primary control is in 'hard lockout' mode. You may have to do something a little extra to reset that mode...

Which primary control do you have? the one with the blinking light... Is it a 7184 ?

If so, there is also a 'bleed mode', where it will run for something like 4 minutes.

If you have an oil line that runs UP out of the tank, and overhead back to the burner, you may need to run that pump for a while before you get the line primed.

Did you say if there are ONE or TWO oil lines back to the tank?

 

Control unit is R7184B. There is One line leading to tank.

 

Hold the reset button for 30 seconds until the LED flashes twice and it will reset from the hard lockout.

To enter the 'bleed mode' push the reset button ONCE at the time that the control is only running the motor, before the oil valve opens. This will extend the lockout time to 4 minutes.

 

Holding the reset button for 30 seconds did the trick.
