If draft hood spillage occurs, check for blocked flue connectors, vent pipes, and

 

 

Continued

 

 

 

 

chimneys. If you find blockage, remove. Test again for spillage. If spillage still

 

 

 

 

 

 

 

 

occurs or there was no blockage, you need more fresh, outside air in the house. You

 

 

 

 

must provide additional fresh-air ventilation. Follow the steps below at once.

 

 

 

 

A. Open a window near the appliance(s) at least two inches. Test again for

 

 

 

 

 

 

spillage. If spillage does not stop, open window more and retest. If spillage

 

 

 

 

 

 

stops, keep window open while running appliance(s). Supply fresh, outside

 

 

 

 

 

 

air by a permanent method as soon as possible. If spillage still occurs, leave

 

 

 

 

 

 

window open and go to next step.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

B. If you have a fireplace, open a window or door near it at least two inches.

 

 

 

 

 

 

Test again for spillage. If spillage does not stop, open window or door more

 

 

 

 

 

 

and retest. If spillage stops, keep window or door open while using fire-

 

 

 

 

 

 

place. Supply fresh, outside air by a permanent method as soon as possible.

 

 

 

 

 

 

If spillage still occurs, leave window or door open and go to next step.

 

 

 

 

C. If you have kitchen and bathroom exhaust fans, turn them off. Test again for

 

 

 

 

 

 

spillage. If spillage stops, do not use exhaust fans. Turn off circuit breakers for

 

 

 

 

 

 

fans if possible. Permanently supply fresh, outside air as soon as possible.

 

 

 

 

Providing Permanent Fresh-Air Ventilation

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If draft hood spillage occurs, you must permanently supply fresh, outside air to the

 

 

 

 

inside of your house. Provide extra fresh air by using ventilation grills or ducts.

 

 

 

 

Connect these items directly to the outdoors or spaces open to the outdoors. These

 

 

 

 

spaces include attics and crawl spaces. If you install this heater in an area with

 

 

 

 

other gas appliances, you must total the BTU/Hr input rating of all appliances.

 

 

 

 

Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1. It lists fresh-air

 

 

 

 

requirements for fuel-burning appliances.

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.
