Not sure if this the right Forum for this question but here it goes, New Navien ch 240 keeps sutting down , Low pressure on heating side error. Installer says is older systems leaky pressure relief valve still in place is beaking up water on top. He said he will come back after holidays to replace and rebleed, unfortunatley now system won't restart at all. Could I somehow shut off the heating side and reprogram until he can get back? Error E002
