During heating cooling cycle open valves 

3. 

C and D, close 

valves A and B.

Maintain a minimum clearance of one (1") inch to 

A. 

hot water pipes. In air handling units where they 

may be exposed to refrigerated air circulation, the 

boiler piping system MUST be supplied with flow 

control valves or other automatic means to prevent 

gravity circulation of the boiler water during the 

cooling cycle.

hot water boilers installed above radiation level must 

4. 

be provided with a low water device either as part of 

the boiler or at the time of boiler installation.
When a  boiler is connected to a heating system that 

5. 

utilizes multiple zoned circulators, each circulator must 

be supplied with a flow control valve to prevent gravity 

circulation.

* Reduced pressure back flow preventer must be 

present under provisions required by the Environmental 
Protection Agency, (EPA).
Bypass piping is an option which gives the ability to 

6. 

adjust the supply boiler water temperature to fit the 

system or condition of the installation. Although, this 

method of piping is not typically required for baseboard 
heating systems.

This method is used to protect systems using 

A. 

radiant panels and the material they are encased 

in from high temperature supply water from the 

boiler. See figure 6 above.

CONNECTING SUPPLy AND RETURN PIPING

This method is used to protect boilers from 

B. 

condensate forming due to low temperature return 

water. Generally noticed in large converted gravity 

systems or other large water volume systems. See 

Figure #7.
This method is used to protect boilers from 

C. 

condensate forming as well as protecting the 

heating system from high water temperature. See 
Figure #8.

Note: 

7. 

When using bypass piping, adjust valves A and 

B until desired system temperature is obtained.
Bypass loop piping must be the same size piping for the 

8. 

supply and return.
Typical installation using circulators is shown in

9.

Typical installation using zone valves is shown in

Figure #10.
See 

11. 

Figure #11 for typical piping for domestic hot 

water heater.
