INSTALLING HEATER

Continued

Installation must include a manual shutoff valve, ground joint union, plugged 1/8" NPT tap and a sediment trap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 7).

Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.

CAUTION

Use pipe joint sealant that is resistant to liquid petro- leum (LP) gas.

Install sediment trap in supply line as shown in Figure 7. Locate sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

IMPORTANT: Use two pipe wrenches when connecting gas piping to gas control valve of heater. This will prevent turning or damaging control valve.

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.
