a. For satisfactory supply of hot water, the V-7
steam boiler must be equipped with a special
tapped rear heater coil cover plate contained in
both of the following kits:
Part No.
6032702 Includes tapped cover plate, mounting
hardware, water temperature limit with well,
and installations instructions.
6032703 As above, except less limit and well.

(lower left hand ¾" tapping in front of boiler).
The use of unions, a shut-off valve, and a drain
Figure 7
valve is recommended for future service
convenience. The use of a flow control or check
valve is required to prevent back flow through
the water heater during operation of the space
heating system.
c. The Alliance™ connection labeled "BOILER
SUPPLY" should be piped to the 1" NPT
tapping in the boiler's aforementioned tapped
cover plate. The circulator should be floor
mounted with full size 1" piping from the boiler
and no flow restrictions in this piping. Be sure
the flow arrow on the circulator points toward
the water heater. The use of a union, shut-off
valves, and a drain valve is recommended for
future service convenience. The use of an in-
line "Y" style strainer is required to prevent
accumulation of sludge in the water heater's
coil.
2. Burnham Independence
®
Series steam boiler (Refer
to Figure 8).
a. The Alliance™ connection labeled "BOILER
RETURN" should be piped to tapping "M" on
the left side of the Independence boiler. The use
of unions, a shut-off valve, and a drain valve is
recommended for future service convenience.
The use of a flow control or check valve is
required to prevent back flow through the water
heater during operation of the space heating
system.
b. The Alliance™ connection labeled "BOILER
SUPPLY" should be piped to tapping "N" on the
right side of the Independence boiler. The water
heater circulator should be floor mounted with
full size 1¼" piping from the boiler and no flow
restrictions in this piping. Be sure the flow
arrow on the circulator points toward the water
heater. The use of a union, shut-off valves, and
a drain valve is recommended for future service
convenience. The use of an in-line "Y" style
strainer is required to prevent accumulation of
sludge in the water heater's coil.
