9.   ATTENTION TO THE BOILER WHILE NOT IN  

If a boiler is not used during the winter months, and 

it is in a place subject to freezing, it must be fully 

drained to prevent freezing damage.

A. Steam Boilers  Procedure for taking steam 

boilers off line at the end of heating season: Drain 

off boiler water until it runs clear while holding the  

boiler temperature between 180 and 200ºF. Then   

refill to top of gauge glass. 

B.  Water Boilers  Since a water boiler is a closed    

system, no draining/refilling should be necessary.

C.  Note any time raw water is introduced into the 

boiler it must be immediately heated to 180°F to 

drive off dissolved gases. If water treatment is 

used, sufficient water treatment compound should 

be added to condition the make-up water.
