Garage Heater (re: gas lines) install help

[lilscorpion]

I have fitted black pipe before but the supply demands of my setup is what I'm unsure of. The inside black pipe is 1-inch. This pipe feeds the fireplace, the HW heater, the back porch, and the furnace. Then there's a T in the line with a ~30 foot of 1/2-inch pipe running to the other side of the house (took 4 90 degree adjustments to get there) where there's a hookup for a gas dryer (I do not have one hooked up). About 10 feet before the end of that run is where I'd like to T and go maybe 15-feet to the Hot Dawg heater I'm installing. The heater is about a 45k BTU unit. That being said I could swear that the run that was installed for the dryer (the long 1/2-inch run) is already undersized for a dryer given the length and the numerous of 90's but don't know for sure.

Anyone know if that setup can handle the additional run with a heater? Am I going to have pressure problems at the heater (low pressure NG)? Would it make a difference if I deleted the dryer hookup and dedicate the run to the heater (screw the next owner, my shop needs heat)?

TIA, Matt

Is the T 1 x 1/2 x 1 or 1 x 1 x 1 with a reducing bushing? If you have the bushing just pull it out an run 1" or 3/4" pipe out to the dryer and garage.

Just check, the T that's in the 1-inch is 1 x 1/2 x 1. Wish it had a reducer.

You can easily look up the pipe size/length for the demand. It might be touch and go with the 1/2" but may work the 45 ok. It may depend on the current demand on that line when your running the heater.

Have a proffesional come in and change the "T", run a new pipe to the heater with another tee for a future run, Don't skimp and do it correctly to code unless your a pro at it yourself.

Per my town code to get inspected, I had to have it done by a licensed installer. Didn't do as good of job as i would have done but i guess thats life.

The current demand would have to be a guess since I don't have a gas dryer hooked up at the moment. That's what I was thinking though.

I'm going to have a local guy come out this week and give me a quote. Seems to make the most sense to pay someone to do the gas line and have it inspected and do the heater part myself. Probably the right time to hire an expert - especially since the main needs to be redone/modified.

See that's exactly my problem. No one I hire seems to spend the time I'd spend to make it right...or I'm too cheap to pay someone to take the time to do it right. Not sure which it is.

Maybe not your self but most people now days have a Walmart mentality .
