supply. Follow all local codes.

 

 

 

CAUTION

Never connect heater directly to the propane supply. This heater requires an external regulator (not sup- plied). Install the external regulator between the heater and propane supply.

The installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 6. Pointing the vent down protects it from freezing rain or sleet.

CAUTION

Use only new, black iron or steel pipe. Copper tubing may be used in certain areas. Check your local codes. Use pipe that is 1/2" in diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur.

The gas supply line to your heater must be 1/2 inch in diameter or larger. If the supply line branches to serve two or more heaters, the line from the branch back to the external regulator must be doubled or tripled, etc., in size (depending upon the number of heaters). Example for 1/2 inch diameter supply line: If the supply line branches to serve two heaters, the line diameter from the branch back to the external regulator must be at least 1 inch. If three heaters are served, the line diameter from the branch back to the external regulator must be at least 1 1/2 inches.

Note: If gas supply line total length exceeds forty feet, use a larger diameter pipe.

Use pipe that is the next size larger than the heater control valve fitting.

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.
