TO USE- 



ELASTIC FIRE BRICK 



In All Your 

 Boiler Work 



Any Handy Man Can Install It. 



Use it for patching when you cannot afford to* cut a boiler out. 

 ELASTIC FIRE BRICK can be used for all fire brick purposes. 



Hocrbcr Bros., Geo. Wittbold Co., Miller Bros., C. Hansennann, John Reading and Broadbeek the Florist 

 are using Elastic Lining. These are only a few of the thousands we are selling.

satisfactory results reported entirely 

 to a deficiency in the amount of radia- 

 tion, but rather to the attempt to supply 

 thirty 1%-inch return pipes with two 

 3-inch flows. It is not claimed that the 

 actual radiation is too great, but the 

 water in the returns will only have to 

 circulate one-fourth as fast as in the 

 flows. The result will be that, while a 

 fairly good circulation may be secured 

 in some of the returns, generally the 

 higher ones, or those that run more 

 direct, there may be little or no circu- 

 lation in some of the others. This is 

 particularly likely to occur when some 

 or all of .the returns are below the top 

 of the boiler, as appears to be the case 

 in this instance. 



"We are not informed regarding the 

 location of the pipes, but infer that the 

 flows are overhead and that a majority 

 of the returns are on the side walls. 

 Using the present piping, we should 

 suggest that one 3-inch flow pipe be 

 placed upon the side wall plates and 

 that each of these supply a coil of eight 

 1%-inch pipes on the side walls. We 

 would also run three 2%-inch flow pipes, 

 placing one under the ridge and the 

 others about halfway between the 

 ridge and the plates, and, with each 

 of these, supply five 1%-inch returns. 

 If the house has solid beds throughout, 

 we should arrange these coils either in 

 the walks or on purlin posts. To favor 

 the circulation, run the flow pipes at 

 a slight downward slope, and, if possi- 

 ble, carry the returns higher than the 

 top of the boiler. 



Our choice of piping for such a house 

 would be five 2 1^ -inch flow pipes and 

 twenty-five 2-inch returns. 



If "the 22.x.35-foot house has fhrce 

 feet of glass in each of the walls, we 

 should use five 2^4 -inch flows and either 

 fifteen 1%-inch or twelve 2-inch re- 

 turns, or three flows and fifteen 2-inch 

 returns. 



In figuring the amount of radiation 

 for a greenhouse, one should not only 

 know the amount of exposed glass, but 

 the minimum temperatures, both inside 

 and outside. Allowance should also be 

 made for the character of the construc- 

 tion of the house and the exposure to 

 the previiiling cold winds. Where the 

 mercury does not drop more than 10 de- 

 grees below zero, it is customary to use 

 one square foot of hot water radiation 

 to three of glass for 60 degrees, and to 

 four square feet of glass if n tempera- 

 ture of about 50 degrees will suffice. 

 For 20 degrees below zero, add twelve 

 to fifteen per cent to the above radia- 

 tion. 



It is important that the number and 

 size of the flow and return pipes be 

 carefully adjusted to the various con- 

 ditions. Thus, we should limit 1^-

as the Chinaman would say, into the heart of the boiler room, the fur- 

 uace. If you find loose and broken bricks and crumbling mortar in the 

 lining, there is the cause of heat loss and incomplete combustion.

will make any furnace absolutely air-tight and gas-tight. No joints where 

 clinkers may stick, no mortar to fall out, no chance for heat loss that eats into 

 your coal -pile. 



Plibrico is a high-grade refractory which comes in plastic form, 

 easily installed. No skilled labor is needed. Ideal for baffle walls, 

 side walls, front-door arches, and combustion chamber arches.
