Installation

INSTALLATION USING A BLOCK-OFF PLATE FOR USA ONLY - INSERT:

If this unit is to be installed into a masonry fireplace or a zero-clearance fireplace with a direct connection you must install a non-combustible seal-off device such as a block-off plate or damper adapter. By installing a block-off plate you seal the chimney, ensuring that no smoke enters the home and sealing the chimney to encourage draft. To construct a block-off plate follow the below steps.

1.Determine where the block-off plate will be installed; above the top of the firebox (it must be high enough to easily install the connection pipe) but below the damper area. Look for a location that

is level and in an area where the plate can be mounted easily.

The measurement that will be needed are as followed (refer to Figure 36 and 37):

A - The width at the front of the firebox at the height where the block-off plate will be installed.

B - The width at the back of the firebox at the height where the block-off plate will be installed.

C - Then depth of the block-off needed (the distance between A and B).

D - The distance of the center of the flue to the front of the fireplace opening. Refer to Step 3.

NOTE: In general masonry fireplaces have square fireboxes while zero-clearance (metal) fireplaces have domed firebox tops. Therefore zero-clearance block-off plates may be more difficult to install. Insulation may be used around the edges to simplify sealing the plate.

2.Create a cardboard template of the dimensions with 2” (51 cm) wide flanges on each side. These flanges will be used to mount the block-off plate to the inside of the firebox. Bend the flanges downwards on the template and place it inside the fireplace. Continue on if the template fits correctly in its planned location. If the template does not fit, make a new template with the required corrections until it does fit correctly.

3.With the template in place, mark the location for the center of the flue pipe when the unit is in place. If installing a 1200 the distance will be approximately 81⁄4” or 9 15/16” back from the fireplace opening. If installing a 1700 the distance will be approximately 123⁄4” or 14 7/16” back from the fireplace opening. Remove the template and cut a 61⁄4” diameter hole centered on this mark.

4.Using the template make the block-off plate of 24 gauge or thicker steel. Drill two (2) holes in each flange for mounting the plate.

1700, 1200 specifications

The Enviro 1200 and 1700 are innovative solutions in the world of air treatment and environmental control. Designed to cater to industrial and commercial needs, these models are pivotal in enhancing air quality and promoting energy efficiency.

One of the main features of the Enviro 1200 is its advanced filtration system. It utilizes a multi-stage filtration process that includes pre-filters, HEPA filters, and activated carbon filters. This combination ensures the capture of particulate matter, volatile organic compounds (VOCs), and other airborne contaminants, providing cleaner and healthier air. The Enviro 1700, while similar in filtration capabilities, boasts a larger capacity, making it suitable for bigger spaces or industrial applications.

Both models incorporate smart sensor technologies that monitor air quality in real-time. These sensors provide data on pollutant levels, allowing for dynamic adjustments to the filtration strength. This not only optimizes performance but also reduces energy consumption, making the Enviro series both eco-friendly and cost-effective. The adaptive response of these systems ensures that users always breathe cleaner air without unnecessary energy expenditure.

Another defining characteristic of the Enviro 1200 and 1700 is their user-friendly interface. These units are designed with digital controls, allowing for easy programming and monitoring. Users can set specific operating schedules and track air quality trends over time. Additionally, both models come equipped with WiFi connectivity, enabling remote control via a smartphone app. This feature allows users to adjust settings or receive alerts about air quality levels from anywhere.

In terms of durability, both the Enviro 1200 and 1700 are constructed with high-quality materials that ensure long-lasting performance. They are designed to operate quietly, reducing the noise levels often associated with air treatment systems. This makes them suitable for a range of environments, from offices and homes to industrial settings.

In summary, the Enviro 1200 and 1700 stand out in the air treatment market due to their state-of-the-art filtration, smart technology integration, and user-centric design. These features, combined with their robust build quality, make them a reliable choice for anyone looking to improve air quality while maintaining energy efficiency.
