To determine the approximate reduction in output from the tank use the following formula: For example, what would the first hour rating be if a model AL53A were installed with a boiler having a DOE heating capacity of 120,000 BTU/h? Increasing the boiler DOE heating capacity above the values listed in Table 3 will not increase the rating of the water heater. 3. Circulator Sizing - Refer to Table 3 for the minimum flow rate through the water heater coil and the corresponding pressure drop through

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 point

5. When the call for heat is satisfied, the damper relay coil is de-energized - closing contacts which energize the damper motor. This causes the damper to close. When the damper blade reaches the fully closed position, the damper motor is de-energized. POWER FAILURE - The damper blade will stop in the position it was in when power failed. (Combustion can never take place unless the damper blade is in the fully open position). G. Sequence of Operation and Wiring. Refer to Table 10 for the approp

Normally open contacts open, stopping boiler operation. Domestic hot water priority only: normally closed contacts close, returning boiler control to space heating. D. b. Adjusting to a higher temperature may not immediately affect water temperature. If a heat- up cycle begins, go to step 3. If a heat-up cycle does not begin, draw sufficient water or allow the water heater to sit until a heat-up cycle is initiated. Repeat step 3. To Shut-off Water Heater C.
