Customer purchased a Rinnai i150SN LP , Installed and pressure tested in an unheated garage. Job has been postponed and Boiler will not be fired until spring. Is it ok to leave installed in garage,? There is no insulation yet and job is in Boston. Owner can put in a small room heater if needed.

    You have three choices. Either make totally, completely, sure that the unit has absolutely no water in it. Or drain and retest with glycol mix. Or heat the garage so it stays reliably above freezing.
