burn out the grate bars, as well as stop the drafts. The glass 

 gauge should be examined frequently to ascertain whether there 

 is plenty of water in the system. A desirable feature is a float 

 valve on the expansion tank which will permit the automatic 

 inflow of water when needed. 



A thermometer connected with the heater to register the 

 temperature of the water is very desirable, but, if one of these 

 instruments is installed, it should be of reliable make, as a good 

 deal of dependence is put upon it. All pipes in the brooder house 

 which are not actually needed for direct radiation of heat should 

 be covered with asbestos to conserve the heat, and all pipes used 

 directly for heating should receive a good coat of paint to prevent 

 rust.
