It's a g400, this will be third winter with it Bought it as a trade in so it was used but came with warranty from local dealer Really looking forward to this winter as the wood I have is the best I've had so far with seasoning time Previous years was always a scramble to get it ready
I add about 3 to 5 gallons every couple weeks to my 1992 Hardy H4. I figured it's normal being an open system to lose some from evaporation. My Hardy has an auto fill feature, but my water level gauge is shorted out. So I don't have it hooked up at the moment.
So far leaks are sealed up, and things are working! Except for no hot water to the house, pump burned out, but luckily my dad had a spare one Swapped, burped, and off to the races!!
