For all Glazing — new work, 

 tightening leaky roofs and re- 

 pairing broken glass. 



EYERTITE 



GLAZING CEMENT 



Applied easily, quickly and eco- 

 nomically with the new "Oh Boy" 

 automatic glazing gun. 



EVERTITE GLAZING CEMENT remains elastic at all times— forming a 

 waterproof and airtight joint over the sashbar. It will stand the extreme 

 expansion and contraction that a greenhouse is subject to and will not check or 

 crack— nor will it harden. It lasts from five to ten years.

TO USE— 



ELASTIC FIRE BRICK 



Any Handy Man Can Install It. 



In AH Your 

 Boiler Work 



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

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



Hoerbcr Bros., Geo. Wittbold Co., Miller Bros., C. Haosermann, John Reading and Broadbeck the Florist 

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

for connectinji with the boiler, about 

 150 feet of :.'-incli, nnd (iOO to G.'jd feet 

 of 1%-inch, or 7J0 to 800 feet of 1%- 

 inch pipe, will be required. 



In case a single main flow pipe con- 

 iiect.s the radiation with tlie boiler, it 

 should be 3-inch, and the main return 

 pipe sliould be of the same size, unless 

 a 2-ineh return is used to connect each 

 of the coils with the boiler. 



GETTING REQUIRED CAPACITY. 



I wish to build a brick stack for :i 

 Metropolitan water heater, number 

 r>24. The heater has a 24y2x27i/.-in(h 

 tire pot, and a 10-inch smoke pipe, rated 

 .it 1,600 square feet. What should be the 

 diameter and height of such a chim- 

 ney? Will this size of boiler heat two 

 greenhouses to 50 degrees in zero 

 weather? The houses are 20.x75 feet 

 each, one on each side of the boiler 

 shed. My plan is to run a 3-incli pi]ic 

 through the shed for the flow and re- 

 turn to each greenhouse and to take off 

 :2-inch jiipes to carry through the green- 

 houses. The return 3-inch main will be 

 about six inches above the top of the 

 boiler. R. I.— Pa. 



Unless the fire surface is moto than 

 usually efficient, a heater with a lO-incli 

 smoke pipe and a grate 24%x27^i; 

 inches would not rate so high as 1,600 

 square feet. In fact, it would not be 

 much above 1,L'00 square feet and, if 

 soft coal is used, the actual amount of 

 radiating surface would be limited to 

 about 950 square feet. 



The size and height of the smoke- 

 stack will depend, to a considerable ex- 

 tent, upon the arrangement of the. fire 

 tubes, but considering the size of tlie 

 smoke pipe and the area of the grate, 

 a chimney twelve inches squ;»re insiile

 smoke pipe enters, would sufTice for 

 O.IO square feet of radiation, unless 

 there are taller buildings in the vicin- 

 ity. If niufh more than O.'iH square 

 feet of radiation is to be supplied, the 

 diameter or height of the chimney 

 should be increased accordingly.
