Just hooked up my used 4400.It was only used one season but sat for 3 yrs. Had all the plumbing and power in place just had to switch out boilers. The blower motor wouldn't come on and it thru a P1 code. Called around and found it was faulty sensor in the back of stove. We took the side tin off and removed the ETC unit. Mice got in there and bared the wires up then they shorted out on the framework. We spliced them and the boiler worked great over night. While we were doing all this my buddies dog caught and killed a mouse. He won't be chewing any more wires. Never remember all these mouse problems in equipment years ago.
