tern? "Would the location of the cir- 

 culation pump make any difference? 



L. C. L.— Pa. 



You give no clear idea of the arrange- 

 ment of the piping in the garage, and 

 hence the best that can be done is to 

 suggest several things which might be 

 investigated. It would appear that the 

 trouble is due to some obstruction of 

 the circulation, either in the main pipe 

 from the boiler, or by the radiators be- 

 ing air-bound. It is hardly probable 

 that the plumber has failed to supply 

 automatic air valves. These, of course, 

 should be near the middle of the last 

 section at the return end of each of the 

 radiators, or at the lower end of each 

 wall coil. 



From the fact that no circulation of 

 steam is reported in any of the radia- 

 tors, it would appear that the obstruc- 

 tion is in the main feed pipe. If there 

 is a flange union anywhere along the 

 line, it is possible that the plumber has 

 failed to cut out the gasket. This 

 would prevent the passage of the steam, 

 and as the steam pressure rises, the 

 water would either be forced out into 

 the returns, or if the check valve oper- 

 ates properly, the boiler would blow off 

 steam. If there are no closed gaskets, 

 look for any obstruction which has by 

 accident been placed in the main. 



While it is always advisable to run 

 all returns with a slight fall, so that they 

 will clear themselves of the drip water 

 by gravity, any slight depression in 

 which water has settled would be 

 cleared by carrying a few pounds, pres- 

 sure on the boiler, so that we cannot as- 

 cribe the failure of the system to work 

 to any such trouble. 



In a gravity system, the lower ends of 

 the return coils should be three or four 

 feet above the top of the boiler, but this 

 is not necessary when either a trap 

 or pump is used. The return pipes 

 should be run to the boiler as direct as 

 possible, but it would hardly be possible 

 to arrange them so as to entirely pre- 

 vent the circulation of the steam. Any 

 pipes intended for heating purposes 

 should, of course, be above the water 

 level in the boiler, but they may drop 

 into the cellar either close to the boiler 

 or at some distance from it. 



Steam pipes naturally become hotter 

 than those in hot water systems, and 

 hence provision- should be made for 

 their expansion. The exact location of 

 the pump is not important, altliougli it is 

 usually near the boiler for convenience.

 opened a retail shop of his own. He has 

 been in the trade for the last three 

 years, in the employ of C. I. Baker, a 

 local florist.
