I just bought the h150 last weekend, and have had the worse time getting it started. I ran 3/4 black pipe out to it as per the manual for 50 ft. Everything is properly was properly set up but it would give me the 1f code. I had the gas company come up and they gave me a larger meter up and said it was a 250btu. The problem is today I finally got it started for the first time after the new meter. However, I forgot to light my hot water tank back up. I shut off the heater and went inside to do so and then tried about an he later and got the 1f again....idk if the gas company can provide me with more pressure or any suggestions?....my hot water tank is 100k btu heater is 150k but, and furnace 75k btu. The gas company said it should be fine because all 3 gas things will not be running at the same time....please help .....tried to call Hayward being the machine is a week old but have waited up to 3 hrs on phone several times and no amswer
