takagi K3 Propane line question

[jordan69s]

Thank you for reading my post!

I have a question regarding the propane line for the heater. I currently have 3/8 solid copper for my stove working just great. The thing is that the heater needs a 3/4 line and the installer tells me I need to run one new line from the propane tank and have a "t" to feed the stove and another "t" for the new dryer and then go to the heater.

I have the feeling that he is just making more work so to get more labor. Why no simply run a straight new line from the tank to the heater and leave the 3/8 alone and simply feed the dryer from the stove connection.

Do that make more sense? The plumber store told me the takagi heaters requires a good flow of propane to work properly, and that splitting the line to feed the stove and the dryer might "starve" the heater....

I am sure you already figure out I am from a small town

Any suggestions or ideas

Many thanks

Typical stove BTU, maybe 60K, same for a typical dryer...typical tankless system 200K. I would think if you ran a new dedicated line from the tank (would need possibly udgrade the regulator there), that would work unless the existing line is not currently up to code. If it is, then replacing it all makes sense. I'd guess 3/8" is marginal for what you have now, but I'm guessing.

What he is informing you is correct. what he is doing is ensuring you have enough delivery for the total BTU drawn from the tank to each appliance.
