9 VI Venting There are three basic ways to vent the BWF boiler: • Horizontal (“si de wall”) venting usi ng an approved AL 29-4C stainless steel vent system.
10 Horizontal Vent System Design 1) See Figure 8 f or the general hori zontal exhaust c onfiguration. For t he purposes of thi s manual, a “horiz ontal exhaust system” is one that exits the st ructure through a wall.
11 5) Minim um Vent Pipe Length: 2 ft + (1) 90 degree el bow + terminal 6) Permitted Terminals: • Choice of Tjernlund VH1 series terminal , a 90-degree elbow with rodent screen , or a termination tee with a rodent screen. The Tjur nlund VH1 term inals may not be used on BWF195s and B WF 229s when they a re vented with 3” pipe .
12 12) Locatio n of Horizontal Ve nt Terminal – Obse rve th e following limitations on the terminal location: • Terminal must be at least 4 feet belo w or 4 feet horizontally from any window, door, or gravity air inlet into the building (Fig. 10).
13.
14 Vertical Vent System Design 1) See Figure 13 for the ge neral vertical stai nless steel venting configuration . For the purposes of this manual, a “vertical exhaust system ” is a Category III ve nt syst em that exits the stru cture through a roof.
15 4) Maxim um Vent Pipe Length: • BWF061 to B WF162 – 39.5 ft + ( 2) 90 degree elbows + cap • BWF195, B WF229 (using 4” ve nt pipe): 37 ft + ( 2) 90 degree elbows + cap • BWF195, B WF229 (using 3” ve nt pipe): 24.
16 11) Pipin g supports – Vert ical and horizontal se ctions of pipin g must be properly supported. See the “Ve nt System Assembly ” section of this manual for more information. 12) Location of vent cap– The lowest discharge opening on the cap m ust be at least 2 feet above any object located within 10 feet (Fig.
17 Removing an Existing Boil er From a Common Chimney In some cases, when an exist ing boiler is re moved from a comm on chimney, the com mon venting syst em may be too large for the remaining appliances.
18 Vent System Assembly 1) General Assembly Notes: a) Where the use of “silicone” is called for in the following instru ctions, use only the following sealants: • Flex-L-Inter national Star-3 4 – GE RTV106 or GE IS806 • Z-FLEX SVE Series II I (“Z-Ven t III”) – Silicone not required for joints between pipe sections.
19 4) Assembly of Flex-L-Intl. Star-3 4 Vent System: a) Star-34 Genera l Notes: • Do not cut Star-34 vent com ponents. • Support hori zontal piping sect ions at interval s of 48” or less. • Vertical venting systems must be supported by at least one Star-34 Firestop.
20 5) Assembly of Z-Flex SVE Se ries III: a) SVE Series III General Notes: • Non-expande d ends of SVE Se ries II piping sections m ay be cut using a viation snips or a 24 thread per inch hacksaw. File or sand t he cut end smooth be fore assembling.
21 l) If a termi nation elbow or tee is use d, a locking band or gear clamp must be use d at either side of t he wall penetration to prevent shifting of the v ent system in and out of the wall. m) To join SVE Series III to the VH-1 term inal, cut off the female en d of the pipe that is to be joined to the terminal.
22 6) Assembly o f Heat Fab Saf-T Vent : a) Saf-T Vent General Notes: • In general, Sa f-T Vent pipe s ections may not be c ut. Exceptions to this a re the Saf-T vent slip connector and connections to the boiler vent collar and the VH-1 terminal . In these cases, use a sharp pa ir of aviation snips, an abrasive cut- off, or a plasma cutter.
23 7) Assembly of Protech FasNSeal: a) FasNSeal General Notes: • Do not cut 4” FasNSeal pipe. The m ale end of 3” FasNSeal may be cut. Cut m ust be square to ensure a proper seal. • Orient FasNSe al vent components so that the arrows on the pi ping labels are in t he direction of flue gas flow.
24 m) To join FasNSeal to a 4” VH-1 terminal slip the female end of the FasNSeal pipe over the terminal connection so there is an overlap of at least 1 ¾”. Ti ghten the hose clamp to m ech anically lock the pipe onto the term inal. Apply and sm ooth silicone over the outside of the joint including the hose clamp in the FasNSeal pipe.
25 VII Gas Piping Gas pipi ng to the boiler m ust be sized to deliver a dequate gas for the boi ler to fire at the nameplate input at a li ne press ure between the m inimum and maxim um values shown on the rating plat e. For more informati on on gas line sizi ng, consult the utility or Part 2 of the National Fu el Gas Code .
26 VIII System Piping CAUTION • INSTALL BOILER SO THAT THE GAS IGNITION SYSTEM COMPONE NTS ARE PROTECTED FROM WATER (DRIPPING, S PRAYING, RAIN, ETC) DURI NG APPLIANCE OPERATIO N AND SERVICE (CIRCULAT OR REPLACEMENT, ETC).
27 7) Manual Reset High Limit (Requi red by some codes ) – This contr ol is required by ASME CSD-1 an d some other code s. Install the high limit in the boiler sup ply piping just beyond the boiler with no interv ening valves. Set manual reset high limit as far above the operating limit setting as possible, but not over 240F.
28 2) Gravity and “Large Water Volume” Systems – The piping s how n in Figure 29 will minimize th e am ount of time that the boiler operates with return temperatures below 120 F on thes e systems. A bypa ss is installe d as shown to divert some supply water directly into the return water.
29 6) Air Handl ers – Where the b oiler is connected to ai r handlers thro ugh which refrigerate d air passes, use fl ow control valves in the boiler piping or other auto matic means to prevent gravity circulation during the cooling cycle.

31 IX Wiring WARNING All wiring and grounding must be done in accordance with the authority h aving jurisdicti on or, in the absence of such requirements, with the National Electrical Code (ANSI/NFPA 70).
32 Wiring Variations 1) Multiple Circulator Zones – Figure 33 shows wiring for tw o or more circulator zones using Honeywell R845As. One fewer R845A is use d than the total number of circulator zones.
33.
34 BWF Control System – Sequence of Operation (Refer to Figures 35 and 36 for BWF ladder and connection diagrams) 1) A call for heat from the thermo stat energizes relay coil 1K (the relay on t he R8285), causing c ontacts 1K1 and 1K2 t o make. Contact 1K1 starts the circulator.
