INSTALLING HEATER

VENTING HEATER (continued)

Proper Size Vent

To safely vent heater, the vent connector pipe must be the same diameter as the draft hood outlet on the rear of the heater. Pipe that is too small can cause flue gas to spill from the heater. Fasten vent connector to the draft hood outlet with a sheet metal screw.

Vent Types

Prefabricated or Masonry All-Fuel Chimney - This is a masonry chimney or a residential-type prefabricated chimney. Only use prefabricated chimneys listed by Underwriters Laboratories (UL), Inc.

Type-B Vent - These vents are made of noncombustible, corrosion resistant material. They are certified by a nationally recognized testing agency. Type-B vents are double-walled pipe. Clearances to combustible construction must be in accordance with the listing of the particular type-B vent. Type-B vents are currently listed as B-1, B-1 1/2, and B-2.

The illustrations below show both vent types. The illustration shows typical construction of each type of venting system. Minimum clearances and lengths are added to the illustrations.

Terminate at least 5' above draft hood. If vent extends over 5' above roof, support with guy wires or braces.

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.
