Question about Heating & Cooling
I had the same problem with this unit and had the heater serviced which fixed the problem. The problem is caused by the pilot flame not being big enough to keep the thermocouple hot, so the heater thinks the flame is out and it turns the gas off! The thermocouple is effectively a switch that is on when hot and off when cold. The pilot flame is supposed to keep it hot, so its on and the main burner will get gas. When its off (ie cold) gas is blocked from the main burner for safety reasons! This manual is for a very similar heater: http://www.rinnaisales.co.nz/tradesmart/rinnai2/pdfs/service_info/171.pdf
You need to get at the pilot and clean it out!
