is greater than is needed, it is impor- 

 tant that the heating pipes be of good 

 size and thus assist in obtaining a 

 rapid circulation. "When a large num- 

 ber of small pipes are used as returns, 

 the water often circulates only in the 

 upper pipes in the coils, or in those in 

 which the circulation is favored. This 

 may reduce the circulation one-half or 

 more and will greatly increase the tend- 

 ency of the water to "boil over." 



Provided there is no glass in the 

 walls, and a temperature of 55 degrees 

 is desired, we would use not less than 

 one 214-inch flow under the ridge and 

 eight li^-inch returns under the 

 benches, and the tendency toward iioil- 

 ing over will be lessened if one 2^ -inch 

 flow pipe is run upon each plate and 

 connected with three 2-inch returns 

 under each side bench. Even though 

 only one 214-inch flow is used, we would 

 prefer to use seven 2-inch returns 

 rather than eight l^^-inch. Except for 

 the danger of boiling over, two 2-inch 

 flows might be used in the house instead 

 of two 214-iDch, as suggested above. 



For 300 square feet of radiation, not 

 more than 400 square inches of grate 

 surface are needed. In cast the boiler 

 has a rocking grate, we would suggest 

 disconnecting two of the sections, one 

 on each side, by taking out the bolts 

 which fasten them to the rocking bars. 

 Fire brick may be used to cover these 

 grate sections and lessen the size of 

 the firebox. Unless the size of the grate 

 is reduced, little will be gained by tak- 

 ing off one or more of the sections. If 

 careful attention is given to the firing 

 we would not consider it necessarj'. 



The flow pipes should run downhill, 

 with the highest point over the boiler,
