parts for part numbers. Whenever possible refer to the
original order by number and date.
Control identification and replacement should not be
attempted by unskilled personnel. Only simple,
easily-identified controls and parts may be obtained
locally. All other controls and parts should be identified
by and ordered from Slant/Fin. Relief/Safety valves must
be ASME rated for the pressure and gross output of the
boiler.
For replacement parts, heating contractors should con-
tact their Slant/Fin boiler distributor.
