B)When joining the various components of the above listed vent systems, the manufacturers’ instructions should be closely followed to insure proper sealing.
C)Use sealant specified by vent system manufacturer for sealing of pipe and fittings. See Figure 4 for proper application of vent pipe sealing for
D)All vent connections must be liquid and pressure tight
E)Flue vent system CANNOT be cut to length. Consult manufacturer’s instructions. For
F)DO NOT use plastic or galvanized flue pipe.
2. Flue Length Restriction
Maximum and minimum equivalent flue length for different systems are given in the tables on page 6. Equivalent flue length is sum of straight flue lengths and equivalent length of elbows. The vent termination is in addition to the allowed equivalent lengths.

3.Installation
A.Horizontal Venting:
Figures 5 and 6 show typical horizontal venting. For combustible wall passage of vent piping a U.L. listed thimble must be used. See Figures 5 and 6 for wall thimble Part Numbers and more information.
B.Vertical Venting:
Figure 7 shows typical vertical venting. A fire stop is required for each ceiling and floor penetration. An existing chimney (see Figure 8) may be used as a chase for vertical venting. Other appliances CANNOT be vented into the same chimney or vent pipe within the chimney.
For both, horizontal and vertical venting, the following points MUST be followed:
A.All Victory II boilers are equipped with a built-in con- densation drain and trap. The trap loop must be filled with water. DO NOT operate the boiler without filling the trap with water to prevent flue gas discharge into space. The drain should extend to a floor drain or to a container which may require emptying periodically.
B.The horizontal vent pipe must be sloped upward from the boiler at a pitch of at least 1/4" per 1 foot of run, so that the condensate from the vent system runs to the drain trap.
C.The horizontal vent pipes must be supported with pipe straps at intervals no greater than indicated by vent pipe manufacturer’s instructions. The vertical portion vent pipe also must be supported per manufacturer’s instructions.
D.Minimum clearances of vent pipes from combustible constructions must be maintained (see Page 3).
E.Common venting with other appliances or another Vic- tory II boiler is NOT allowed.
F.The vent piping must terminate with a screened elbow or tee. See Figures 5 and 6 for horizontal and 7 and 8 for vertical termination information. A cap termination may be used for vertical venting.
G.See Appendix A for vent system location and conden- sation drain requirements.
H.For roof passage of vent piping a U.L. listed roof flash- ing must be used.
