VICTORY II VHS Models

VENTING SYSTEM REGULAR INSPECTION

A.Inspect the system regularly for condensation, corrosion and/or physical damage. A qualified professional should ser- vice the boiler annually and include such an inspection at that time. The homeowner should look over the system monthly for damage, 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 condition should be corrected by a qualified professional.

C.All Victory II boilers are equipped with a built-in condensation 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. 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 assembly, straightened out to clear the obstruction, reformed, filled with water and reinstalled as before.

GAS PIPING

A.Local installation codes apply. The pipe joint compound used on threads must be resistant to the action of liquefied petro- leum 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 VHS-150 is to be installed. Distance from gas meter to the boilers 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 on this page (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, insuf- ficient heat and other installation difficulties. For more informa- tion and also if other appliances are to be attached to the piping system, 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 disconnected from the gas supply piping system during any pressure testing of that sys- tem 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 during any

pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG.

D.All gas piping used should be inspected thoroughly for clean- liness before makeup. A sediment trap must be provided, as illustrated on page 2.

E.The minimum and maximum gas supply pressure (at the inlet of gas valve) are shown on the boiler rating plate for the type of gas used. Gas supply pressure should never be less than minimum or more than maximum pressure when the boiler or any other appliance is turned on or off.

ELECTRICAL WIRING

DANGER: Before wiring, always turn off electric power supply, otherwise, shock or death can result.

1.Power Supply

Aseparately fused circuit is recommended. Use a standard 15 Amp. fuse or breaker and 14 gage conductors in BX cable or conduit.

Provide disconnect means and overload protection as required. See boiler wiring diagram (Figure 11a) and ladder diagram (Figure 11b).

Boiler must be electrically grounded in accordance with the requirements of the authority having jurisdiction, or, in the absence of such requirements, with the National Electrical Code, ANSI/NFPA 70-latest edition.

2.Power Connection

A.Remove electrical junction box cover.

B.Hot connection lead is black. Neutral connection lead is white.

C.Connect ground wire to ground screw inside the junction box.

D.Replace junction box cover.

3.Thermostat Connections

Thermostat wire connections must be to T and TV screw ter- minals of Aquastat. See wiring diagram, Figure 11a.

4.Multi Zoning

For pump zoning system, see Figures 12 and 13, for zone valve system, see Figure 14. DO NOT use boiler transformer to power external accessories like zone valve and relays, overload and/or burned-out transformer and boiler malfunc- tion can result.
