Sorry, it's been a long time. This old beast runs beautifully. I've had it checked and have been repeatedly told to keep it clean inside (I have, fastidiously) because they just don't build boilers like that anymore. Checks out more efficient than the vast majority of new boilers on the market. I know I need a new expansion tank, I have the old style original to when it was first purchased. I've always been a do it yourselfer, and like to be at least informed on it if I have someone come in (had one guy come in to swap a zone valve and purge the system, hasn't worked right since, makes noises that I suspect is vapor lock) or have the ability to fix minor issues as I run into them. If anyone happens to run into a manual or further info as to who manufactured this for Monkey Wards, I would be eternally grateful. Thanks guys.
