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
service 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, corro-
sion or damage, the boiler should be shut down immediate-
ly and the condition should be corrected by a qualified pro-
fessional.
C. All Victory VSPH 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. Periodic
inspection should be made of this assembly for deteriora-
tion 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 lique-
fied petroleum 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 manu-
al 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 (W/m)
(BTU/cu. ft.).
3. Divide boiler rated input by heating value to find gas
flow in piping (m3/hr.) (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 9144 mm (360 in.). Heating
value of natural gas is 10 557 W/m3(1020 BTU/cu. ft.) Select
proper pipe size.
Gas flow = 43 965 W/hr. = 4.16 m3/hr.
10 557 W/m3
(Gas flow = 150,000 BTU/hour = 147 cu. ft. per hour)
1020 BTU/cu. ft.
At 9.1 m (30 ft.) length of pipe, match required capacity from
table on this page (choose higher capacity, in this case 4.3
m3/hr. [152 cu. ft. per hour].) Required pipe size is 3/4".
Improper gas pipe sizing will result in pilot flame outages,
insufficient heat and other installation difficulties. For more
information and also if other appliances are to be attached to
the piping system, see Appendix C of National Fuel Gas
Code ANSI Z2231 latest edition or CSA B 149.1 latest edition
for natural gas and propane.
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 3.5 kPa (1/2 PSIG). This boiler must be isolated
from the gas supply piping system by closing its individ-
ual manual shutoff valve during any pressure testing of
the gas supply piping system at test pressures equal to or
less than 3.5 kPa (1/2 PSIG).
D. All gas piping used should be inspected thoroughly for
cleanliness before makeup. A sediment trap must be pro-
vided, 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 gauge 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 Canadian Electrical
Code, CSA-C22-1, Part 1-latest edition.
