a half feet of glass in the ends and one 

 side. 



For 60 to 70 degrees in the new house, 

 run three 214-inch flow pipes to the 

 east end. Place one of them four feet 

 below the ridge and one on each of 

 the plates. Extend the middle flow 

 into the salesroom -as ia 2-inch pipe and 

 take off a 2-inch flow from the end of 

 the flow pipe carried on the soyth plate, 

 and run it into the old house through 

 the salesroom. For returns use ten? 2- 

 inch pipes in the new house and eight 

 in the old house. In. the new hou^e 

 locate three returns on each wall and 

 connect four with the center flow pipe. 



There shoVild be two radiators, each 

 containing sixty square feet of radia- 

 tion, in the salesroom, and a l^Ainch 

 pipe should be extended into the 

 kitchen to supply the radiation needed 

 there; from there a 1-inch pipe should 

 be run into the bathroom. For use with 

 a Wilks heater, I would advise install- 

 ing some form of circulator.

 would such a boiler take care of in this 

 climate, in southeastern Missouri?

_^ boiler of the size mentioned is 

 rated at about sixty, hvreie-power and it 

 would handle about 5,000 square feet 

 of radiation. The amount of glass that 

 could be heated by the boiler would 

 depend upon the temperature to be
