Dayton Installation, Operation, Maintenance and Parts Manual

Models 1RVT7 and 1RVT8

!WARNING

Improper or insufficient ventilation may result in

explosion, fire, health problems, carbon monoxide poisoning or

death. Vent enclosed spaces and buildings according to national, state, provincial and local codes.

This infra-red heater must be vented in accordance with national, state, provincial and local codes and the guidelines throughout this manual. Refer to the latest edition of the ANSI Z223.1 (NFPA 54) Standard.

It is required that the upper levels of the space to be heated are properly ventilated to supply combustion air to the heaters and to sufficiently dilute the products of combustion. It is also important to keep the flue discharge area clear of gas piping and electrical wiring (see Figure 2.10).

Provisions must also be made to provide sufficient fresh air intake area and exhaust air outlet area. Natural or mechanical means shall be provided to supply and exhaust at least 4.0 CFM per 1000 BTU/H of gas input. Exhaust openings for the removal of flue products must be above the level of the heater(s).

displacement is required. A balanced system is essential to avoid negative building pressure which causes excessive infiltration, unfavorable drafts and affects combustion efficiency.

Air displacement may be accomplished by either gravity or mechanical means. Mechanical exhausters are preferred and typically mounted at high points on the roof over where stagnant air accumulates inside. For

a flat roof, considerations of prevailing winds, high and low pressure areas, and distribution of air movement must be taken into consideration when locating exhausters.

Best air distribution is accomplished by using a number of small exhausters versus one large exhauster. Provide a minimum of one square inch of inlet area per 1000 BTU/H for combustion air supply. Inlet opening in the building should be well distributed, located high on the wall and should direct incoming air upward to dilute products of combustion while preventing drafts at lower levels. Inlets are typically 1 to 3 sq. ft.

In certain applications, local codes may require that mechanical exhaust systems be interlocked with the heaters to enable both to function simultaneously or allow control of exhausters with a ceiling mounted humidistat.

1RVT7, 1RVT8 specifications

Dayton 1RVT8 and 1RVT7 are innovative products designed for various applications while setting new standards in performance and efficiency. These models are primarily designed for HVAC and ventilation systems, providing reliable and cost-effective solutions for both commercial and residential settings.

One of the distinguishing features of Dayton 1RVT8 and 1RVT7 is their energy efficiency. Both models are engineered to minimize energy consumption while delivering optimal airflow. This is achieved through advanced motor technology, which utilizes high-efficiency motors that not only reduce operational costs but also comply with stringent energy regulations. The units operate at low wattages, making them an environmentally friendly choice.

The design of these units emphasizes durability and reliability. Built with high-quality materials, they are constructed to withstand challenging conditions, ensuring a long service life. The robust design minimizes maintenance needs, allowing users to enjoy uninterrupted operation. This reliability is further enhanced by the inclusion of thermal protection, which safeguards the motors from overheating, thus prolonging their lifespan.

Dayton 1RVT8 and 1RVT7 also feature an array of user-friendly controls and settings. The intuitive control panel allows for easy adjustments, offering multiple speed options to cater to specific airflow requirements. This versatility ensures that users can optimize performance depending on their unique needs. Additionally, the units are compatible with various smart home systems, enabling automated control and integration into broader building management systems.

In terms of noise level, both models operate quietly, ensuring minimal disruption in their surroundings. This characteristic is particularly beneficial in environments where noise pollution needs to be reduced, such as offices, healthcare facilities, or residential spaces.

Another key characteristic of Dayton 1RVT8 and 1RVT7 is their compact design. The units are designed to fit in tight spaces, making them suitable for installation in areas where traditional equipment would be impractical. This space-saving feature is a significant advantage for many users looking to optimize their floor plans without sacrificing performance.

Overall, Dayton 1RVT8 and 1RVT7 represent a powerful combination of efficiency, durability, and versatility. They are well-suited for a variety of applications, making them a top choice for users seeking reliable, high-performance ventilation solutions. Whether for heating, cooling, or air circulation, these models deliver on the promise of quality and functionality.
