TWO-TEMPERATURE OPERATION OR FEATURE
When using Electro’s zone controller in priority mode, the boiler system
can automatically raise the outlet temperature with zone 1 calling. This
is setup for default of 150° or pulling a jumper peg the high temperature
value is 176°. See appropriate zone controller installation manual for
details.
BOILER/PLUMBING KIT PLACEMENT
This model series is wall hung and the vessel must be vertical, drawing BX501.
The plumbing kit items are located adjacent to the boiler housing itself as shown on drawing BX501 or
BX502.
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
