Final answer:

The fuse plug in an HRT boiler is located in the rear head, but without specific standards or manufacturer's instructions, the exact distance above the top row of tubes cannot be definitively stated.

Step-by-step explanation:

In the context of an HRT boiler (horizontal return tubular boiler), the fuse plug is an essential safety device. It is designed to melt and relieve pressure in the case of a low-water condition, which could otherwise lead to a boiler explosion.

While configurations can vary, a common placement for the fuse plug is in the rear head. For specific boilers, standards or manufacturer's instructions will stipulate the exact positioning. However, without specific reference to a standard or a particular boiler design, it is not possible to definitively state the correct distance above the top row of tubes. Therefore, I can't provide a confident answer to the choice of distances given in your question, namely 2 inches, 1/2 inch, or 1 inch.
