a forced air furnace or air handler, operating at a higher static. After installation, the compatibility of the two pieces of equipment must be confirmed by measuring the airflow’s of the Heat Recovery or Energy Recovery Ventilators by using the balancing procedure found in this manual. It is always important to assess how the operation of any HRV/ERV may interact with vented combustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.). NEVER -install a ventilator in a situation whe

The main supply and return lines to/from the HRV must be 6 inches (150 mm) minimum. Branch lines to the individual rooms may be as small as 4 inches (100 mm), but 5 inch (125 mm) lines are preferred.If the floor is the only option available, then special care should be taken in locating grilles. Areas such as under baseboard heaters will help to temper the air. Also optional inline duct heaters are available for mounting in the supply duct work to add heat if required.In homes with a forced air

The Pitot tube should be connected to a magnehelic gauge or other manometer capable of reading from 0 to 0.25 in. (0-62 Pa) of water, preferably to 3 digits of resolution. The tube coming out of the top of the pitot is connected to the high pressure side of the gauge. The tube coming out of the side of the pitot is connected to the low pressure or reference side of the gauge. Insert the Pitot tube into the duct; pointing the tip into the airflow. For general balancing it is sufficient to move th

Once the humidity level returns to desired condition, the unit will return to the normal mode. 2 wire installation Dehumidistat - MD-4W - The wall mount dehumidistat offers the same features of the dehumidistat I plus additional off/on control for the HRV. Dial illuminates when in override mode. 4 wire installation Air Quality Sensor - AQS - The wall mount Air Quality Sensor (AQS) monitors indoor air quality and activates the override mode when carbon monoxide, formaldehyde, benzene, volatile or

The siding standoff must sit flush against the exterior fascia material. 7. Combustible Exterior Wall Only: Slide the wall firestop over the vent pipe before connecting horizontal run to vent cap (see Figure 12). 8. Carefully move fireplace, with vent assembly attached, toward wall and insert vent pipe into horizontal termination. The pipe overlap should be a minimum of 11/4" (see Figure 13, page 10). 9. Combustible Exterior Wall Only: Slide wall firestop against interior wall surface and attach
