I think I know the answer to this, but I recently had a 399K btu Ray Pak heater installed. My current gas meter is for only 275K. Nicor sat on my request to upgrade for almost a week until I called and now are saying they cannot get out until 7/29. I am pushing them hard to get here faster, but am I correct in assuming that the heater would simply not function correctly if I tried to use it with my current meter? Even for a short period of time?
