VICTORY VSPH Models

CAUSE

8.Defective pressure switch. POWER and PRES SWITCH LED’s flashing

9.Defective high limit control

10.Defective inducer motor

11.Defective gas valve

12.Defective boiler control module

B. NOT ENOUGH HEAT

CAUSE

1.Thermostat setting is too low

2.Boiler water maintained at too low temperature.

3.Circulator not running.

4.Boiler water level too low.

5.Restriction or obstruction in air intake or venting system.

C. BURNER WILL NOT SHUT OFF

CAUSE

1.Defective Aquastat (high limit control)

2.Aquastat sensor is not properly inside Aquastat well.

REMEDY

8.Check pressure switch. Replace defective pressure switch.

9.Set high limit setting above boiler water temperature, LIMIT LED should turn on. If not, turn off power to the boiler, remove wires to high limit and check continuity across high limit contacts. If contacts are open, replace high limit.

10.With thermostat calling for heat and high limit setting above boiler water temperature, remove blower motor plug from boiler control (P4 connector). Check for 120 V between ter- minally 3 and 5 of P4 on control (See Figure 13a and 13b). If voltmeter indicates 120V, replace inducer assembly.

11.a. Check all above causes.

b.check the gas supply pressure (at the inlet of gas valve) as shown on the boiler rating plate for the type of gas used.

c.With thermostat calling for heat and high limit setting above water temperature, check the voltage across terminal PV & PV/MV, if 24 VAC presents, replace the gas valve

12.Check all above causes. If all red indicator lights are off while there is call for heat replace control module.

REMEDY

1.Set thermostat at higher setting

2.Set Aquastat at higher setting.

3.With thermostat calling for heat, check for power to circula- tor. If power is O.K but circulator is not running, replace cir- culator.

4.Carefully snap open relief valve handle to determine if boil- er is full of water, if not full of water, check for system leaks and check water pressure regulator. Repair any system leaks. Adjust or replace water pressure reducing valve.

5.Inspect flue and air intake piping. Inspect termination.

REMEDY

1.Turn off power to the boiler. Remove red and blue wire from Aquastat terminals. Restore power. Check boiler operation, if burners stop firing, replace Aquastat.

2.Insert the sensor into the well.

VSPH-180, VSPH-60 specifications

Slant/Fin is a renowned name in the heating industry, renowned for its innovation, quality, and efficiency. Among its popular offerings are the VSPH-180 and VSPH-60, two highly efficient gas-fired residential boilers designed to provide reliable heating for homes.

The VSPH-180 is a high-efficiency residential boiler that delivers exceptional heating performance while being mindful of energy consumption. It operates at an impressive AFUE (Annual Fuel Utilization Efficiency) rating of up to 95%, meaning it uses 95% of the fuel burned for heating, resulting in lower energy bills and reduced environmental impact. The VSPH-180 features a durable stainless steel heat exchanger that not only contributes to its efficiency but also prolongs the boiler's lifespan.

On the other hand, the VSPH-60 is a slightly smaller but equally efficient model that is perfect for apartments or smaller homes. It also boasts a remarkable AFUE rating of up to 95%, ensuring cost-effective heating solutions. The compact design of the VSPH-60 allows for easy installation in various locations, making it a versatile choice for homeowners seeking space-saving options without compromising on performance.

One of the standout technologies in both models is the modulating gas valve, which adjusts the burner’s output to match the heating demand. This feature enhances energy efficiency by preventing the boiler from working harder than necessary, ensuring consistent temperatures and reducing wear on the unit. Furthermore, both models are equipped with a built-in electronic ignition system, eliminating the need for a pilot light and adding convenience for homeowners.

The VSPH series is designed with maintenance ease in mind. It features a user-friendly control panel that provides easy access to critical information, allowing for straightforward diagnostics and service. Regular maintenance can be performed with minimal disruption, enabling owners to keep their systems running optimally throughout the heating season.

In conclusion, the Slant/Fin VSPH-180 and VSPH-60 represent excellence in residential heating technology. With high AFUE ratings, durable construction, and advanced features, both boilers provide efficient and reliable heating solutions, ensuring comfort and energy savings for homeowners.
