elbows, one 1/2" cap, one 1-1/2" to 1/2" bushing, one 

 1-1/2" x 1/2" tee, one 1-1/2" to 1/2" coupling reducer, 

 one 1-1/2" x 3" nipple. 

 Instructions: 



1) Cut and thread all pipe to dimension indicated on plan. 



2) Drill 1/8" holes at 3" intervals on opposite sides of 1/2" 

 pipe. 



3) Assemble 1/2" steam pipe in following order: Screw 12" 

 pipe into valve on steam line, elbow onto 12" pipe, 3" 

 nipple into elbow, 1-1/2" x 1/2" bushing onto nipple, 33" 

 pipe into opposite side of bushing, screw cap on end of 

 pipe. 



4) Assemble water jacket as follows: Screw tee on 1-1/2" 

 bushing, connect 6" nipple into tee, screw valve onto 

 nipple, connect valve to water main. Screw 1-1/2" pipe 

 into tee, on opposite end screw 1-1/2" x 1/2" reducing 

 coupling, connect 3" nipple, elbow, another 3" nipple 

 and valve to control flow of warm water. 



Note: The temperature and flow of water can be con- 

 trolled by regulating the flow of steam and cold water. Where 

 a boiler is used in connection with dairy room, this is a good 

 way to heat the water for the cows.
