MULTIPLE BOILERS 

 

This boiler series now includes a method for automatically staging any 
number of parallel-plumbed boilers.  Order plug-in relay EB-C-STG5. 

 

The thermostat is connected only to the first boiler, when all stages are 
on for more than 5 minutes, this new plug-in relay module turns on the 
next boiler (R and W), and a second EB-C-STG5 could be used to turn 
on the third, etc. 

 
 
 
BOILER/PLUMBING KIT PLACEMENT 

 

This model series is wall hung and the vessel must be vertical, drawing BX505. 

 

The plumbing kit items are located adjacent to the boiler housing itself as shown on drawing BX501 or 
BX505. 

 

For future servicing, the unit itself must be installed 20” or more above the floor, the elements are 
screwed in from the bottom. 
 

INFORMATION/WATER FLOW CALCULATIONS

 

 
Water flow, GPM, can easily be calculated if the temperature rise across the electric boiler can be 
measured. 
 
The formula below can only be used when the temperature rise is stable and the boiler is not hi-limiting.  
In other words, verify constant current draw and stable outlet temperatures for at least 15 minutes. 
 
 

GPM = Volts x Amps x 3.4 

 

 

        500 x Temp. rise 

 

INSTALLATION REQUIREMENTS

 

 
1.

 

All installation work must be performed by trained, qualified contractors or technicians.  Electro 
Industries, Inc., sponsors installation and service schools to assist the installer.
