1.Remove vent system components from box and inspect for damage. If the carton has been crushed or mutilated, check components very carefully for damage. DO NOT install if any damage is apparent.

2. Remove the combustion air tee assembly from the vent termination. Set the tee aside for later use.

3.Refer to the appliance manufacturer’s specifications for vent termination location.

The location of the vent termination must be installed with the manufacturer's recommendations, and/or local codes that are applicable. In the USA according to the latest version of the National Fire Protection Association NFPA-31, National Fuel Gas Code ANSI Z223.1. Where requirements for venting standards differ the most stringent standard shall apply. In Canada according to the latest version of CSA B140 and the CSA B139 Installation Code. Refer to the following requirements or See Diagram A for typical locations.

a.The exit termination of mechanical draft systems shall not be less than 7' above grade when located adjacent to public walkways.

b.A venting system shall terminate at least 3' above any forced air inlet located within 10'.

c.The venting system of other than a direct vent appliance shall terminate at least 4' below, 4' horizontally from, or 1' above any door, window or gravity air inlet into the building.

d.The vent termination of a direct vent appliance with an input of 50,000 BTU's per hour or less, shall be located at least 9" from any opening through which vented gases could enter the building. With input over 50,000 BTU's per hour, a

12" termination clearance shall be required.

e. The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped structure.

f. The vent termination should not be mounted directly above, or within 3' horizontally from an oil tank vent or gas meter.

g.The bottom of the vent terminal shall be located at least 12" above finished grade or expected snow line, which ever is greater.

4.After determining the location of the venting system termination (See Diagram A), cut a hole in the wall sized according to “L” dimension in

Table 1. (See Figure 1)

5. Seal the back side of the base plate around the outer pipe of the vent termination with a bead of high temperature silicone sealant. (See

Figure 2) Mount the vent termination through the wall, keeping the outer

pipe centered in the hole. (See Figure 1) Fasten the vent termination to the outside wall with appropriate fasteners. Seal the edges of the vent termination base plate to the wall with a high-temperature silicone sealant.

6.Mount the backing plate over the outer pipe. Fasten the backing plate to the inside wall with appropriate fasteners. (See Figure 2)

DO NOT BLOCK the intake or exhaust openings, or the intake access panel on the vent termination body. Wood or vinyl siding should be cut so that the unit mounts directly on the wallboard to provide a stable support. If the siding is greater than 1/2" thick use a spacer plate or board behind the vent termination mounting plate. (See Figure 2)

FDVS specifications

The Field Controls FDVS (Field Digital Ventilation System) is a sophisticated solution designed to enhance indoor air quality while promoting energy efficiency in residential and commercial spaces. This innovative system utilizes advanced technologies to control ventilation effectively and ensure optimal air circulation.

One of the main features of the FDVS is its smart control interface, which allows users to program and monitor the system remotely via a mobile application or web portal. This connectivity enables real-time adjustments and diagnostics, providing users with the ability to optimize their ventilation settings based on current air quality conditions and occupancy levels.

The FDVS employs a range of sensors to monitor indoor air quality parameters, including temperature, humidity, and levels of airborne pollutants. This data-driven approach allows the system to dynamically adjust airflow to maintain a healthy indoor environment, mitigating the effects of indoor air pollution, allergens, and excessive humidity. By intelligently regulating ventilation, the FDVS not only improves comfort but also reduces energy consumption and operating costs.

Another significant characteristic of the FDVS is its variable speed fans, which enable precise control over airflow. This feature allows the system to operate quietly and efficiently, providing sufficient ventilation without causing draughts or disruptive noise. Users can customize the fan speed according to their specific needs, ensuring an optimal balance between air quality and energy use.

Field Controls has also incorporated advanced filtration options into the FDVS, including HEPA filters and activated carbon filters. This two-stage filtration system not only captures larger particles such as dust and pollen but also adsorbs odors and volatile organic compounds (VOCs), further enhancing the air quality in indoor spaces.

The FDVS is designed with a focus on user-friendly operation and maintenance. The system includes easy-to-access filter compartments for straightforward replacement, and the intuitive interface provides reminders for regular maintenance checks. Additionally, the compact design of the FDVS makes it suitable for installation in various environments, including tight spaces where conventional ventilation systems might not fit.

In summary, the Field Controls FDVS is an advanced digital ventilation solution that combines smart technology with effective air quality monitoring and advanced filtration. Its main features, such as remote control capabilities, variable speed fans, and comprehensive sensing technologies, position it as a leading choice for anyone looking to optimize their indoor air quality while promoting energy efficiency.
