First and foremost.  BTU put out by the gas meter, and then all the other appliances.  In order to meet "code" the meter must meet the total BTU's demand by all appliances at one time.  The problem with these on demand heaters is they use up close to 199K btu instead of the normal water heater of about 50k btu.  90% of the meters up here are 250K btu.  Take away the 199k for the tankless and that doesn't leave much for the furnace, stove (oven and all 4 top burners), bbq and fireplaces.  In some instances the tankless must be removed as it screws up all the other appliances. 

The gas line will need to be the proper size as well.

Most tankless cannot use the old B-vent through the roof.  They require stainless steel vent lines.  That should be checked as well.

We just had a local meeting and the Master Plumber said these were the big issues.

There is nothing sweeter than the smell of fresh cut grass on a baseball infield, the click of a wooden bat and the taste of a hot dog at a warm sunny daytime double-header.
