There is a drain plug on the inlet/outlet header.

Those particular heaters can be tricky because they came a few different ways, including a millivolt to electronic spark conversion that was done on site.
Your best bet is to get an old pool tech out there to see if they can get it fired up. The variables involved are far too extensive to troubleshoot in this format. Good luck with it.

ROL would signify an open roll out safety switch. This is a small ceramic part with two wires plugged onto it and one screw holding it to the front of the burner compartment. This is there so that if the flame reaches the front compartment it opens and shuts down the heater to prevent burining up all the wiring and destroying the heater. This can be caused by a high wind while the heater is running, but can also be caused by a plugged up heat exchanger. It is an inexpensive part and easily replaced. Just be careful and always keep your face and body away from the front of the heater when firing it after doing repairs.

Hi,
If it is doing nothing then you need to investigate this with an electrical meter and find out where the power is not going...
The first place I would check is to see if you are getting power to the transformer...and then if 24v power is coming out of the transformer...

If this is happening the check the control module.. that is the next thing and is probably the bad part...

ErrorAO means BlowerVacuum Switch Open. If the blower prover switch does notclose after the blower starts the control will stop the ignition trial go intolockout. The blower will continue to run. Automatic reset is immediate afterthe switch closes. So you need to check this.
