Heating for zone 1 does not work properly. Seems that during the day it's not heating at all and zone1 temp is around 63F even if I set the thermostat to 69 or 70. At night the temp in zone 1 is about 68. outside it's actually colder (24F) so I don't know what's going on.Zone 1 and hot water work fine. Zone 2 is stuck in open position (Honeywell 8043f, lever has no resistance). Zone 2 only (and always) provides heat if hot water or zone 1 is requesting heat. However, if Zone 2's thermostat is requesting heat, the circulator and furnace do not come on. This is a one circulator system.1. The ability to reuse inverted flare valves and/or fittings has limita - tions, at some point the joint will no longer seal. 2. The valve and fittings should not be supporting any pipe loads. 1.
