SECTION D: WATER PIPING - GENERAL
The boiler should be located so that any water leaks will not cause damage to the adjacent area or structures.
All units should be plumbed in accordance with the appropriate diagram from Section E, F or G or per a suitable engineered piping arrangement.
CAUTION:
This boiler requires forced water circulation when the burner is operating. See Table
RELIEFVALVE PIPING
WARNING:
Pressure relief valve discharge piping must be piped near the floor close to a floor drain to eliminate the potential of severe burns. Do not pipe to any area where freezing could occur. Refer to local codes.
HYDROSTATIC TEST
Unlike many other types of boilers, Raypak boilers do not require hydrostatic testing prior to being placed in operation. The heat exchanger has already been
Leaks must be repaired at once to prevent damage to the boiler. NEVER use
1.Connect fill water supply. Fill boiler with water (be sure bleed valve is open). When water flows from bleed valve, shut off water. Close bleed valve. Carefully fill the rest of the system, being sure to eliminate any entrapped air by using high point vents. Close feed valve. TEST AT standard operating pressure for at least 24 hours.
2.Make sure constant gauge pressure has been maintained throughout test.
3.Check for leaks. Repair if found.
LOW TEMPERATURE SYSTEM
Boiler requires minimum inlet temperature of 105°F. Consult sections E, F or G for piping details. (For Pool temperature requirements, See Section G).
TEMPERATURE & PRESSURE GAUGE
The temperature and pressure gauge is
