12 A. V ent System Design There are three basic ways to vent this boiler: • Horizontal (“Side W all”) Concentric V enting - V ent system exits the building through an outside wall. Concentric venting consists of a “pipe within a pipe”. Flue gas exits the building through the inner pipe and combustion air is drawn into the boiler through t[...]

39 Method 2: Direct Connection to Heating System (Generally NOT Recommended) The FCM can be connected directly to the heating system as is done with conventional boilers (Figure 9.8). If this is done, the fl ow rate through the boiler will equal the fl ow rate through the system. The fl ow rate through the system must therefore always remain wit[...]

40 C: Standard Piping Installation Requirements Observe the following guidelines when making the actual installation of the boiler piping: 1) The relief valve is packaged loose with the boiler and must be installed in the location shown in Figure 2.1. The relief valve is set to open at 30 psi. If the valve is replaced, the replacement must have a r[...]

41 2) Circulator (Required) - Usually at least two circulators will be required to properly install a FCM Series boiler . See the previous section for information on sizing the circulators. 3) Expansion T ank (Required) - If this boiler is replacing an existing boiler with no other changes in the system, the old expansion tank can generally be reus[...]

51 1 1) Perform a combustion test. Boilers equipped with a concentric vent system have a fl ue gas sample tap located in the boiler vent collar (under the screw cap). For other vent systems, the sample probe may be inserted into the terminal. If this is not possible, remove the fl ue temperature sensor and insert the analyzer probe in the sensor [...]

52 W ARNING Each FCM series boiler is tested at the factory and adjustments to the air- fuel mixture are normally not necessary . Consult a U.S. Boiler representative before attempting to make any such adjustments. Improper gas valve or mixture adjustments could result in property damage, personal injury , or loss of life. 12) T est any external li[...]

53 XII Operation 1) The FCM boiler uses a microprocessor based control, known as a “MCBA”, to manage all boiler functions including fl ame supervision and modulation. T wo set point or “target” boiler supply temperatures are stored in the MCBA ’ s memory; one for space heating and one for domestic water production. If an outdoor temperat[...]
