OUTSIDE, to insure against leaks from cocked nipples
or through concealed breakage caused in shipping and
handling. This precaution is for your protection and
will simplify handling of necessary replacements and
adjustment claims. After making certain that there are
no leaks, drain boiler and remove plugs for boiler trim
and other connections.
