Instructions / Assembly

2. SPLIT LOOP Provides more even
heat distribution and the option of
separate zone control. The house is
“divided” into two (or more) sec-
tions, each with its own circuit.
Each circuit draws water of the
same temperature from a central
trunk line. Balancing valves should
be installed in each circuit at return
end just before entering circulator.
3. ONE PIPE WITH DIVERTER TEES
Permits individual room shut-off or
thermostatic control. Each base-
board unit is connected to the main
by a supply and return branch con-
nection (usually with a shut-off
valve at the diverter tee). This offers
a sophisticated system of room
temperature control, particularly in
conjunction with Slant/Fin’s fully
modulating damper.
air elimination...
Provision must be made for venting air from system, to prevent
noise or blockage of circulation by air pockets. Either install a
manual air vent at every drop, or install an automatic air eliminator
device at the boiler and a vent at highest point of the system for
extra safety. A vent at every drop is an advantage in case the sys-
tem is later drained and refilled without purging.
