hi, i’ve just bought and installed a rinnai 1000FT spaceheater with power flue, it has a problem when first igniting, when i press the on button the green light comes on and combustion fan operates pre purge, then gas ignites on low burner, then the red light comes on and combustion fan operates on high, which is all the things it’s meant to do, but then the unit shuts off completely and i have to start again, maybe 5 or 6 times before it actually keeps running. any suggestions as to what the problem might be would be greatly appreciated.
cheers, mick.
