Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. When you were connecting the piping did you put sealant on the male end of the pipe and also inside the fitting? Did you convert the diaphragm in the stove for the proper fuel? Was the gas meter sized so that it could be the correct size for the added stove? Is the connection for the stove made after or before a regulator?
I did originally ask what type but after reading again and seeing the part about the meter, I realized that it was NG and edited that part out. Did you bleed the air out of the line? What type of pipe did you use? Are you sure about the pipe sizes? That seems like a very large supply of 1 1/2". The meter is 1 1/2"?
That seems like it would be a very large meter for the house but probably not 1 1/2". It should say on the meter. To get a proper pressure test on the gas you need a manometer for a wc value. The water column value is much easier to go by since gas pressure is so low. So, you connected the gas line by the furnace or straight from the meter? Wherever you connected it, did you connect the supply before or after a regulator?
Yes you state that you ran a 3/4 pipe from an existing tee in. You also described a tee at the furnace. The tee at the furnace is likely not for a future connection but a drip leg. It is for catching debris and moisture. If this is where you connected it then that is not the best way to go. The drip leg is important to collect moisture and debris. I read it a few times but was not clear as you described the meter and size and the furnace piping. I only wanted clarification and also wanted to know if it was connected before or after a regulator. There are regulators depending on W.C. value and demand. I also asked earlier if the gas company sized your meter when doing the pressure test and also if they tested the W.C. value or actual pressure. Did they use a manometer and did they size your meter? I am not asking these things again because I am not reading your replies or your description. I am asking again because they have not been responded to and also for clarification as I have not seen this project and am needing to be certain of things before being able to get you a definitive answer.
I hope you understand why I would have mentioned the drip leg and I am sorry if my inquiries for clarity are bothersome but there is a means to an end here. I had to run out on an emergency call so I am also sorry about that. There were not seconds to spare for that situation. Gas pressure is not tested with a pressure gauge but with a manometer. I would like to know what the water column value is. I suspect that you may have too much gas pressure. If you could find that value and compare it to the maximum gas pressure for the stove that would be helpful to determining the issue.
