Pitco sg14r-js fuel rail
I have 3 fryers on a fuel rail with a 1 1/4″ quick disconnect by dormont. How do I attach it properly to a 3/4″ black iron gas pipe? I used a street elbow but they won’t light. Assuming I need to purge air out but how to do it safely and is this proper sizing and do I need bigger gas line? I can hard pipe them individually?

Anytime you add a piece of Gas equipment to a Kitchen, You have to check the supply to be sized correctly and able to provide adequate fuel at pressure. First, what type of fuel? Next you can access gas flow charts from the Gas code book or your gas supplier will help. The whole building has to be considered, not just the kitchen manifold. You will have to check the manufacture's tags for everything in the building on you gas service for BTU ratings. Add them all together for your total demand to calculate the service and do the same on you line. I can guarantee that if you are on Natural gas, 3/4 line will be undersize for a cooking line.
I had a customer that wanted to open a seafood restaurant and couldn't get a CO. When I got involved and reran his gas lines I also had to have the utility upgrade his meter capacity. Also add fresh air make-up for hot water heater.

Do you mean 1 1/4″ gas service line to 3/4″ gas fitting to 3/8″ disconnect? Because that's the usual set-up and what I have for my 3 – 40lb. fryers on my cooking line in my restaurant.

It all depends on the fryer. Make and BTU's would be nice information on this.

If it's Nat Gas!
Be aware, the SG14R's have been made with many different nozzles and BTU's depending on altitude and user. BK, AW, and PH have all had specials. Also, pressure loss from pipe distance and fittings adds up fast. Especially Quick connects. Prety certain that that fryer has to have a 1 1/4 disconnect for flow. One usually puts a street ell on the fryer manifold so the quick connect hose bends down with a loop and back up to the wall manifold gas cock.
