ing or servicing. Correct all leaks at once.

 

 

 

 

WARNING

Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION

Make sure external regulator has been installed be- tween propane supply and heater. See guidelines under Connecting to Gas Supply, page 11.

Pressure Testing Gas Supply Piping System

Test Pressures In Excess of 1/2 PSIG

1.Disconnect heater and its individual manual shutoff valve from gas supply pipe. Pressures in excess of 1/2 PSIG will damage heater regulator.

2.Cap off open end of gas pipe where manual shutoff valve was connected.

3.Pressurize supply piping system by either using compressed air or opening propane supply tank valve.

4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

Test Pressures Equal To or Less Than 1/2 PSIG

1.Close manual shutoff valve (see Figure 8).

2.Pressurize supply piping system by either using compressed air or opening propane supply tank valve.

3.Check all joints from propane supply tank to manual shutoff valve. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Pressure Testing Heater Gas Connections

1.Open manual shutoff valve (see Figure 8).

2.Open propane supply tank valve.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from manual shutoff valve to control valve on heater. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 20 through 22). Check the rest of the internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appliance, page 22).

GVB50P, GVB35P specifications

The Vanguard Heating GVB35P and GVB50P models represent a significant advancement in home heating technology, designed to cater to the needs of residential spaces with varying heating demands. These gas-fired boilers not only ensure optimal warmth but also focus on energy efficiency and user-friendly operation.

One of the main features of the GVB35P and GVB50P is their impressive heating capacity. The GVB35P is suitable for smaller homes or apartments, with a heating output of around 35,000 BTU, while the GVB50P is designed for larger spaces, offering an impressive 50,000 BTU. This versatility allows homeowners to select the most appropriate model for their specific requirements, ensuring efficient heating without unnecessary energy consumption.

Both models incorporate advanced condensing technology, which significantly enhances their efficiency ratings. By capturing and reusing heat that typically escapes through the flue in traditional boilers, the GVB35P and GVB50P achieve high Annual Fuel Utilization Efficiency (AFUE) ratings. This not only reduces the overall energy bill but also contributes to a lower carbon footprint, making these models an environmentally conscious choice.

The construction of the GVB35P and GVB50P features robust, durable materials aimed at maximizing longevity and reliability. The heat exchangers are designed to withstand high temperatures and pressures, ensuring safety and durability. Additionally, these models are equipped with a modulating gas burner, which allows for precise temperature control and minimizes energy wastage during operation.

User convenience is further enhanced by the inclusion of a built-in digital control system. This allows homeowners to easily adjust the heating settings remotely, ensuring homes are warm upon arrival without requiring constant manual input. Moreover, the low maintenance requirements of these models make them appealing to busy homeowners, as regular service intervals are reduced.

In summary, the Vanguard Heating GVB35P and GVB50P models combine advanced technology, high efficiency, and user-friendly features to deliver exceptional heating performance. Their durable construction, energy-saving capabilities, and modern controls make them an excellent choice for homeowners looking to enhance comfort while minimizing environmental impact. Whether for a small apartment or a larger home, these boilers stand out as a reliable heating solution.
