Using reducer on the 1" Hot/Cold water connection on indirect hot water heater.

hello.

If a indirect hot water tank comes with both TOP and SIDE domestic water connection with TOP being 1" and Side being 3/4".  The house domestic pipe size to and from the existing hot water tank is a 3/4", 

Due to this new tank's layout, using the top connection is a bit easier for piping with a corrugated stainless steel pipe - I want to know is it a problem to just use a Brass 1" to 3/4" reducer on the top the heater directly?  

The heater in question is this one.

  1. Use the Hot and Cold 1" outlet, with a reducer to 3/4". Add mixing valve on top and connect to existing 3/4" pipe.
  2. Cap off the Side 3/4" HOT water pipe opening.
  3. Add a drain valve to the side 3/4" COLD water pipe opening.

Does this make sense to you?

thanks,
