Slant/Fin Line 30 - Manual (Page 6)

plan your piping...
Here are examples of three basic piping systems, shown with and without options
for zoning.
1. SERIES LOOP
Series loop--single zone
(The simplest, most economical
system to install.) The Slant/Fin
baseboard damper provides indi-
vidual room control. A single cir-
cuit runs from the boiler to the first
run of baseboard, continues from
there to the next room and so on.
The last baseboard unit in the
series is connected to the return
at the boiler. It keeps pipe, fittings,
controls and labor costs to a mini-
mum. Use separate loop for each
zone.
Series loop--multiple zones
Each zone is a “Series loop” with
any number of Slant/Fin base-
board units and controlled by its
own room thermostat.
In the zone valve arrangement,
each zone has an electrically
operated zone valve and there is
a single pump for the whole
system.
In the zone pump arrangement,
each zone is provided with a
pump, a flow control valve and a
relay.
Series loop--multi-zone with
individual pumps
