Thanks so much HeatPro. The new boiler was installed to replace an old Heatmaker and some old piping was reused. The pipes has only a single loop, no subloop. In this situation, did you mean that we have to follow the 'pump-away' rule and put the expansion tank on return piping? Right now very high pressure is trapped in the system and somehow it can not reach the expansion tank to be reduced. We are trying to figure out why. Any suggestions? Thanks.
: With only about ten feet of pipe between the Endurance boiler supply and return there is no significant piping drop to be concerned about having the 'pump away' configuration. If the expansion tank is on the return coming from the main, only miniscule flows would be affected by it being there. However, it is better to be on the safe side of advisement; especially when answering a question that might ASS U ME the idea that someone could pipe the boiler into the system in the older 'traditional' supply from the boiler and return to the boiler without the loop-subloop idea (possibly to save the cost of another circulator.)
: In summation:
: DID YOU PIPE THE SYSTEM LOOP-SUBLOOP as instructed in the installation instructions? If so, there isn't much concern. If you didn't pipe as directed then you MUST use the pump-way piping as directed, or the warrantee is void.
