	NATURAL DRAFT CHIMNEY	AND TYPE “B” VENTING

V-90, V-120, V-150 and V-180 boilers may be vented into a chimney (see “Chimney and type “B” venting” paragraph on page 4) or into a type “B” vent, ONLY when converted to the 5" dia. Slant/Fin flue collar supplied unassembled with these boilers and ONLY as described here, other places in this booklet and in figures 6a and 6b.

Standard vent connector materials (i.e. galvanized or stain- less steel vent pipe). Condensate drain and liquid tight seal is required. See figures 6a, 6b and “Chimney and type “B” venting” on page 4.

V-33, V-60, V-90, V-120, V-150 and V-180 may be vented horizontally and vertically ONLY when boilers are equipped with the Slant/Fin factory installed 3" dia. flue collar and adapter is used ONLY as described here, other places in this booklet and figures 7, 8 and 9.

ONLY 3" dia. single wall Saf-T #AL 29-4C▲stainless steel manufactured by Heat-Fab, Inc. may be used. Condensate drain and liquid and pressure tight sealing is required. See figures 7, 8, and 9.

The condensate drain should be installed as close to the boiler as possible. The drain fitting size is 3/8" or 1/2"depending on the type of drain assembly. Clear plastic tubing (3/8" I.D. or 1/2” I.D.) sized to fit the fitting must be connected to the drain fitting. The clear tubing should be formed into approximately a 4-5 inch diameter loop to form a trap. The loop should be tied with cord or a cable tie where the loop crosses over itself. See figures 6,7,8 and 9. This loop should then be filled with water to form a liquid filled trap. DO NOT OPERATE THE BOILER WITHOUT INSTALLING THIS TRAP AND FILLING WITH WATER. Periodic inspection should be made of this assembly for deterioration of the tubing and to insure that the trap is not plugged. If it is plugged or appears to have excessive sediment in it, it should be removed from the drain assem- bly, straightened out to clear the obstruction, reformed, filled with water and reinstalled as before. The drain should extend to a floor drain or to a plastic container which will require emptying periodically.

D. WHEN VENTING HORIZONTALLY, COMMON VENTING

WITH OTHER APPLIANCES IS NOT ALLOWED.

VERTICAL PRESSURE VENTING

Vertical pressure venting (not natural draft chimney and type “B” venting) is allowed with the 3" flue collar and adapter and #AL 29-4C▲stainless steel vent system previously shown in “Hori- zontal Pressure Venting” paragraph No.1. This arrangement is shown in Figure 9.

Note, that when using a 3" diameter vent for vertical pressure venting, a chimney may be used as a chase for a vertical vent (support is required in conjunction with firestop as per vent manufacturers’ instruction). The 3" vent system MUST extend the total length of the chimney but not longer than the equivalent length limitations indicated on page 5 under “HORIZONTAL PRESSURE VENTING” paragraph 2A. Other appliances can NOT be vented into the same chimney.

As noted previously, all Victory boilers MUST be installed with a condensate drain trap. Vent system must be sealed liquid and pressure tight.

The instructions indicated in “HORIZONTAL PRESSURE VENT- ING” on pages 5 and 6 must also be followed for the above described Vertical Pressure Venting except, use figure 9 includ- REGULARing the clearancesINSPECTIONshown in figure 9 in place of figures 7 and 8.

A.Inspect the system regularly for condensation, corrosion and/or physical damage. A qualified professional should service

the boiler annually and include such an inspection at that time. The homeowner should look over the system monthly for dam- age, water stains, any signs of rust, other corrosion or separation of the flue (vent) tubing and fittings.

B.Should an inspection turn up signs of condensation, corrosion

or damage, the boiler should be shut down immediately and the GASconditionPIPINGshould be corrected by a qualified professional.

A.Local installation codes apply. The pipe joint compound used on threads must be resistant to the action of liquefied petrole- um gases.

B.The gas supply line to the boiler should be run directly from the meter for natural gas or from the fuel tank for L.P. propane gas. See page 2 for location of union and manual main shut- off valve that may be specified locally.

Selecting pipe size for natural gas:

1.Measure or estimate the length of piping from the meter to the installation site.

2.Consult gas supplier for heating value of gas (BTU/cu. ft.).

3.Divide boiler rated input by heating value to find gas flow in piping (cu. ft. per hour).

4.Use table below to select proper pipe size.

Example: Boiler model V-150 is to be installed. Distance from gas meter to the boiler is 30 ft. Heating value of natural gas is 1020 BTU/cu. ft. Select proper pipe size.

Gas flow =	150,000 BTU/hour =	147 cu. ft. per hour
	1020 BTU/cu. ft.

At 30 ft. length of pipe, match required capacity from table below (choose higher capacity, in this case is 152 cu. ft. per hour). Required pipe size is 3/4".

Improper gas pipe sizing will result in pilot flame outages, insuffi- cient heat and other installation difficulties. For more information and also if other appliances are to be attached to the piping sys- tem, see Appendix C of National Fuel Gas Code ANSI Z223.1- latest edition.

C. The boiler and its gas connection must be leak tested before placing the boiler in operation. Use liquid soap

solution for all gas leak testing. DO NOT use open flame. This boiler and its individual shutoff valve must be discon- nected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSIG.

This boiler must be isolated from the gas supply piping system by closing its individual manual shutoff valve dur- ing any pressure testing of the gas supply piping system
