Dimensions and Speci¿ cations
BASE-RAY TAPPINGS- Tapped 3/4" top and bot-
tom of end sections. A 3/4" x 1/8" vent bushing is
furnished with each Base-Ray Assembly. Only one air
vent location need be used.
Copper tubing is not recommended for steam applications due to high heat loss through the tubing and
thermal expansion noise.
Maximum recommended length for steam applications is 10
lineal feet.
Base-Ray® Assembly Chart
BASE-RAY Assemblies up to and including 6 lineal ft. are
shipped in one piece.
Longer Assemblies are shipped in two or more pieces or subassemblies, none of which exceeds 6 lineal ft.

BASE-RAY® HYDRONICS
Types of Systems
Hydronic Heating Systems are classi¿ ed according to the pip-
ing arrangement and heating medium employed. BASE-RAY
is very versatile in that it may be used in almost all types of
systems as noted below:
1. Series Loop Forced Circulation Hot Water
2. One-Pipe Forced Circulation Hot Water
3. Two-Pipe Reverse Return Gravity or Forced Circulation
Hot Water
4. Two-Pipe Steam or Vapor.
It is not recommended that BASE-RAY be used in a One-Pipe
Steam System.
System Description
1. Series Loop is a forced circulation hot water heating system
with the BASE-RAY Assemblies connected so that all the
water À owing through a circuit passes through each series-
connected Assembly in the circuit. Thus, the Assemblies
serve as portions of the main.
2. One-Pipe is a forced circulation hot water heating system
utilizing one continuous main from boiler supply to boiler
return. BASE-RAY Assemblies are connected to this pipe
or main by two smaller pipes known as branches. When
connecting these branches to the main, one of the standard
tees is replaced by a special tee frequently called a one-pipe
¿ tting. These one-pipe ¿ ttings cause a portion of the water
À owing through the main to pass through the BASE-RAY
Assemblies and back to the main again.
3. Two-Pipe Reverse Return is a gravity or forced circulation
hot water heating system utilizing one main to carry heated
water from the boiler to the BASE-RAY Assemblies and a
second main to carry the cooled water from the Assemblies
back to the boiler. The Assemblies are connected to the
return main in the reverse order from that in which they are
connected to the supply main. Very few designers use this
type of system for residential applications, since there is
no difference between the heating qualities of this system
and the other two hot water systems.
4. Two-Pipe Steam or Vapor Systems are steam systems in
which each BASE-RAY Assembly is provided with two
piping connections, and where steam and condensate À ow
in separate mains and branches. The Vapor system differs
from the low pressure system only in the type of air valve
used.
