I'm looking at a used EKO 40 tomorrow and have a few questions. I read some old threads and will inspect the bottom refractory and nozzle for cracks/wear. Guy is selling because he's tired of dealing with wood and the boss (wife) is tired of the smell/dust/mess. The unit was used with return protection to the boiler so that is good.
- How can I tell if it's the new vs old controller? I understand the new version goes up to 195 max vs 175 I think...
- Can/should I bring some fittings and an air pump or compressor to pressure test it?
- What else should I check out?
