Slant/Fin VSPH-180 Venting and AIR Intake System Regular Inspection, GAS Piping, Power Supply

VICTORY VSPH Models 15

VENTING AND AIR INTAKE 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 corrosions or separation of the vent and air intake piping (if direct-vent).

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 VSPH boilers are equipped with a built-in conden- sation 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 tub- ing 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 petroleum gases.

B.The gas supply line to the boiler should 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 VSPH-150 is to be installed. Distance from gas meter to the boilers is 30ft. 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 pip- ing 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 solu- tion 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 test- ing of that system at test pressures in excess of 1⁄2 PSIG. This boiler must be isolated from the gas supply piping sys- tem 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 cleanliness before makeup. A sediment trap must be provid- ed, 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

A separately fused circuit is recommended. Use 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 13a) boiler con- trol (Figure13b) and ladder diagram (Figure 13c).

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.
