 of the coils to main returns of the same 

 size. Just how many feet of 4-inch 

 pipe will be needed will depend uJ5on 

 the location of the boiler and the ar- 

 rangement of the piping, and the 

 amount might vary anywhere from fifty 

 to 100 feet. Not far from 500 feet of 

 2%-inch and 1,700 feet of 2-inch pipe 

 will be needed for the two houses. In 

 the hotbeds use a 2-inch pipe to make 

 a complete circuit, with the flow pipe 

 on one side and the return on the other.

 duplicate orders is the proof. This Valve will main* 

 tain a steady pressure on the low side, no matter 

 how the Initial pressure fluctuates. By carrying 40 or 50 

 pounds pressure on the boiler and setting the valve to 

 carry 5 or 10 pounds on the line, you always have a 

 reserve to fall bacli on in rase of a sudden drop in tem-
