I would go with 1 1/2. It's a little overkill, but 1 1/4 would be cutting it pretty close.
A 1 1/4 inch line will supply 280,000 BTUs at 200 feet, that is as far as my chart goes. A 1 1/2 inch line will supply 480,000 BTUs at 200 feet.

I would agree if the pressure is 7-9" WC or 1/4 to 1/2 lb of pressure 11/2" pipe would be suffcient ... unless you decide to use a corigated style ...then you need to cionsult with the manufactuers recommendations because due to the uneven surface inside the pipe ... sometimes you jump up one size.

Consider stepping up to a 2lb gas system. Especially if you are connecting your gas line near your meter as you can get away with a T and a "whole house 2lb-1/2lb regulator" The money you save on gas line should more than cover the cost of puting in a regulator or 2. My gas utility upgraded their end for free, I just had to take care of things after the meter.

2lb gas I dont think any utility co is giving you for a residential home. Size the gas line properly and you'll have no issues... 2lb gas should be welded joints and not recommended for a residence.

Are you sure about that? Maybe things are different in your neck of the woods but around here 2lb gas is standard in new homes and for retrofits where people want to add more gas appliances without installing new gas lines.
It's very common and there is no requirement for welded fittings, etc. Utility company upgraded me to 2lb gas no questions asked and for free.

Yep, 2LB of NG off my meter at my house. Ran 1/2" poly about 150ft to my garage to run my water heater.
I decided to put a meter at my garage and my local utility company gave me the option of having them set it at 6"h2o or 2psi. 2 PSI is standard here now for all new construction and new service.
My house was renovated in 2002 and it has a 2PSI service.
