(63.5mm) nipple (X, as shown in Step a on
previous page). Tighten to 109 ft•lb (148 N•m).
d. Hang a blow down card (W) (enclosed) as
close to the control (A) as possible, or remove
the protective backing and affix the card on
the boiler jacket close to the control.
To prevent burning or scalding, pipe blow-off
discharge from blow-down valve to floor –
allowing enough height for a pail under dis-
charge pipe to collect blow down discharge.
This pipe must be same 3/4” size as blow-
down connection; do not reduce. Do not
thread end of pipe.
