This is the grate that will not become clogged. Will not shake fine coal through into the ash pit. Will open wide enough 

 to pull the cinders through without disturbing the fire. Will successfully handle soft coal, which makes a great amount 

 of cinders and ashes. Also hard coal, making a great amount of fine ashes. Use better grates and increase your heating 

 capacity. Regulate your draft and save fuel. Have control of your grates and lessen your responsibility. Give size of 

 furnace and we will send prices with full information.

Pel five feet above, but this is no bet- 

 ter. It appears that the hot water 

 flows almost directly into the barrel 

 and then, when cool enough, takes a 

 gravity run into the mains. From past 

 experience in cold climates, I think 

 ten li^-inch returns and two 2*inch 

 mains should be sufficient to heat a 

 house twice that size. Where is the 

 trouble? Of course, lowering the boiler 

 w^ould help a great deal, but where 

 should the expansion pipe on any hot 

 Water boiler be connected? I have

insure a more uniform tem- 

 perature in the houses by 

 keeping all steam lines free 

 and clear of condensation. 



Sluggish lines sap the real 

 heat value out of the new 

 steam and add dangerously 

 to the general inefficiency 

 of the plant. 



Avoid this condition in 

 your system by installing 

 a "Detroit" Return Trap. 



Bulletin No. 326- WF gives details of construction, operation 

 and application of Detroit Traps. Yours upon request.

 selection of the proper size " Detroit " Trap for your requirements, write us.

 novices, and I am still puzzled as to 

 which is right. H. H. K. 



The boiling over of the expansion 



tank is caused by the circulation being 

 too sluggish to cool the water in the 

 boiler, and perhaps by the boiler being 

 too large for the amount of radiation. 

 If the boiler is rated for more than 250
