B & G Monoflo Fittings make possible the use of a single pipe
to act as both a supply main and a return main. These fittings
connect the risers to the main and assure proper diversion of
water to each terminal unit, whether radiator, convection, baseboard
or fan-coil. They can be installed on the supply or return riser,
or both, depending on the pressure drop through the side branch
circuit and terminal unit.
Only one fitting needed on most installations
In most cases using radiators, convectors, or baseboard, one Red
Ring Monoflo Fitting is needed to provide adequate diversion for
upfeed radiation. Only when high resistance units are used or
when radiation is downfeed are fittings required on both supply
and return risers.
How to use B&G Monoflo Fittings
· Be sure the ring is between the risers or
· Be sure the supply arrow in the supply riser and the
return arrow on the return riser point in the direction of the
flow.
For radiator above the main-normal resistance
For most installations where radiators are above the main, only
one Monoflo Fitting need be used for each radiator.
For radiators above the main- high resistance
Where characteristics of the installation are such that resistance
to circulation is high, two fittings will supply the necessary
diversion capacity.
For radiators below the main
Radiators below the main require the use of both a supply and
return Monoflo Fitting. However, use a single return fitting on
a ¾" main.
