CATEGORY II AND III VENTING

1.Vent Material

A)The vent system for horizontal or vertical venting

(Category II and III) must be UL listed single wall 3" diameter AL29-4C▲stainless steel material. The follow- ing manufacturers’ systems are approved for use within a specified minimum and maximum equivalent vent length for each model. Proper adapter must be used as a connector between Victory II boilers flue collar and venting system as shown below:

Manufacturer	Type/System	Adapter Part	Sealant
		No.
Heat-Fab. Inc.	Saf-T Vent	Not Required	RTV 106 or Dow
			Corning 732
Heat-Fab. Inc.	Saf-T Vent	Not Required	Not Required
	EZ Seal
ProTech System,	FasNSeal	FSA-SLB-3	Not Required
Inc.
Flex-L	StaR-34	SRASFA3	GE-1S806
International, Inc.
Z-Flex, Inc.	Z-Vent	O2SVSSLA2	GE, RTV 106

Heat-Fab Part Numbers for various items of vent system are listed in Slant/Fin Part List, Publication No. VHS-10PL.

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 Safe-T vent system by Heat-Fab. Inc.

D)All vent connections must be liquid and pressure tight

E)Flue vent system CANNOT be cut to length. Consult manufacturer’s instructions. For Heat-Fab system, use slip joint connector to adjust pipe lengths dimensions.

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.

Example: Boiler Model VHS-180 is to be installed at sea level with 2 elbows using Heat-Fab vent system. Maximum straight run would be: 40 - 2 x 3 = 34ft. If same boiler is to be installed in Colorado Springs (5,980 ft. altitude), the maxi- mum straight run would be: 20 - 2 x 3 = 14 ft.

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.
