Water & Steam Control Tapings

NOTE: The boiler jacket must be installed before connecting the heating system piping and controls.

All heating system piping must be installed by a qualified technician in accordance with the latest revision of the ANSI/ASME Boiler and Pressure Vessel Code, Section IV, and ANSI/ASME CSD-1, Standard for Controls and Safety Devices for Automatically Fired Boilers. All applicable local codes and ordinances must also be

followed. A minimum clearance of 1" must be maintained between heating system pipes and all combustible construction.

CAUTION: Improper piping of this boiler can cause flooding and extensive property damage!

Ensure that the boiler is level from front to back and from side to side. Use metal shims to level the boiler. NEVER use wood, plastic or other combustible materials as shims.

If a boiler is installed above any radiation elements it must be fitted with a low water cutoff device.

WATER BOILER PIPING CONNECTIONS

The supply and return connections should be sized to suit the system, see Figure 94 & Table 4. Do not pipe the supply from the bottom port or the return to the top port, the boiler will not work properly.
