Otherwise, if air noises occur during summer months the space heating system would have to be operated to purge air at the main purger. 2. For a space heating system that utilizes ZONE CIRCULATORS AND A BOILER BYPASS, refer to Figure 4. The Alliance™ connection labeled "BOILER SUPPLY" should be piped to the boiler supply piping as close to the boiler as possible and especially before the bypass piping. Mount the circulator as close as possible to the water heater making sure the flow arrow points toward the water heater. The use of a shut-off valve is recommended for future service convenience. The use of an air purger and vent is recommended to eliminate air in the system during warmer periods when the space heating system is not operating. Otherwise, if air noises occur during summer months the space heating system would have to be operated to purge air at the main purger. Figure 3: Water Boiler Piping with Zone Valves and a Boiler Bypass Figure 4: Water Boiler Piping with Zone Circulators and a Boiler Bypass 11 3. For a space heating system that utilizes ZONE VALVES WITHOUT A BOILER BYPASS, refer to Figure 5. The Alliance™ connection labeled "BOILER SUPPLY" should be piped to the boiler supply piping after the air purger and before the space heating circulator. Mount the water heater circulator as close as possible to the water heater making sure the flow arrow points toward the water heater. The use of a shut-off valve is recommended for future service convenience.

For a space heating system that utilizes ZONE CIRCULATORS WITHOUT A BOILER BYPASS, refer to Figure 6. The Alliance™ connection labeled "BOILER SUPPLY" should be piped to the boiler supply piping after the air purger and before the space heating takeoffs. Mount the water heater circulator as close as possible to the water heater making sure the flow arrow points toward the water heater. The use of a shut-off valve is recommended for future service convenience. H. Connect steam boiler piping (See Figures 7 thru 10). valve is recommended for future service 1. Burnham V-7 Series steam boiler (Refer to Figure 7). 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. b. The Alliance™ connection labeled "BOILER RETURN" should be piped to tapping "R" (lower left hand ." tapping in front of boiler). The use of unions, a shut-off valve, and a drain 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. Figure 7 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 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. 12 Figure 8 3. Typical steam boiler with connections available below the water line (Refer to Figure 9). a. The Alliance™ connection labeled "BOILER RETURN" should be piped to a tapping in the boiler that is below the lowest permissible water level. 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 heatin...
