Using CSST Gas Line for New Modine Garage Heater

[BillChoneser]

New here so thanks in advance for the advice and direction…

Just bought a 60K Modine Hot Dawg and am having a buddy help install it in my 3 car garage. Since the house has existing CSST ran for the fireplaces, furnace and water heater – and has a couple free spots in the manifold, he suggested running CSST to the new garage furnace and simply strapping the gas line to the drywall inside the garage and up the ceiling to the unit. Does this seem like a good practice? I know this would be fine with black pipe but is it the same with CSST? Appreciate any insight here and / or direction.

That's exactly what I did,
Had a licensed guy hook it up, no complaints.

Having it exposed actually offers the advantage that you know exactly where it is and can avoid driving nails through it!!

Can't just blindly connect CSST to "manifold" and expect it to work for 60K Btu heater. CSST flows LESS than black pipe steel due to smaller size and corrugated inside texture.

OP . . . need Length of that run . . . and proposed Size of CSST you're thinking of using.

Also, what size of pipe feeds everything up to that point, and what other NG demands are there in the house ?? Adding the demands of heater may starve your house furnace.

I would rather have black pipe anyday.
I would rather cut sheetrock, get the pipe in the wall...and then transition to csst wherever you end up uptop.

One other thing to check is the service pressure on your house. I know most of the CSST houses around here are on 2 psi. If so, a regulator is required in front of each appliance.

Note that if the house is on 2 psi, it won't matter how you pipe it...you'll still need a regulator.

3/4" CSST pipe running approximately 60'
Other appliances on NG are a fireplace, water heater, furnace and outdoor firepit.

How protected are the areas you plan on running the CSST ??

Does the 60' run connect pretty much right after meter ??

As HoosierBuddy asks . . . VERY IMPORTANT . . what is Gas PRESSURE ??

I ran 3/4" CSST underground (10' from gas meter on side of house to closest wall of detached garage, 20" deep) I ran this thru 1-1/4" PVC (combo between plumbing PVC and electrical PVC due to electrical having wider radius bends available) and 4' up the garage wall, there will be a shutoff at that point, my heater inlet is 1/2", thoughts were to switch to 1/2" black pipe the rest of the way; 6' farther up the wall, 18' horizontal, into a 90, then 3' horizontal to another 90*, then 30" drop into gas valve.
