tank capacity should allow for increase in water volume of the heating
system, including the boiler, radiators or coils, and all piping.

LOW WATER CUTOFF
The boiler is as standard with a probe-type low water cutoff. If boiler is
supplied with a ball/float type low water cutoff, a blowdown valve should be
installed off the lower plugged cross to facilitate routine checking for proper
function of the cutoff control.
2.5
HYDRO TEST
Good practice, as well as, most local codes, dictates that a hydrostatic test, at
a pressure equal to the safety valve setting, of the entire boiler system be
performed prior to boiler start up. All leaks, both boiler and piping, should be
“stopped” at this time.
NOTE: SMALL LEAKS (LESS THAN 2 DROPS PER MINUTE) BETWEEN THE BODIES
OF THE ELEMNT COMPRESSION FITTING AND THE ELEMENT FLANGES
USUALLY STOP DURING THE FIRST FEW DAYS OF BOILER OPERATION.
LARGER LEAKS, HOWEVER MAY NECESSITATE TIGHTENING OF THE
COMPRESSION FITTING BODY. THIS IS ACCOMPLISHED BY FIRST
REMOVING THE ASSOCIATED WIRES/JUMPERS, AND THEN TIGHTENING
THE COMPRESSION BODY
.
CAUTION:
DO NOT TORQUE BRASS COMPRESSION BODY OVER 70 FT LBS
NOTE: ALL PIPING, VALVES, AND FITTINGS MUST MEET THE REQUIREMENTS OF
LOCAL REGULATING CODES. THE RESPONSIBILITY FOR THE INSTALLA-
TION OF THIS BOILER RESTS WITH EITHER THE OWNER OR THE
INSTALLING CONTRACTOR
