System draining
The drain cock ring nut is located under the
safety valve inside the boiler.
To drain the system, turn the ring nut (ref. 3
- fig. 27) counter-clockwise to open the
cock. Do not use any tools; use hands only.
To drain only the water in the boiler, first
close the shut-off valves between the sys-
tem and boiler before turning the ring nut.
