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 where its normal operation, lack of operation or partial failure may result in the backdrafting or improper functioning of vented combustion equipment!!! Your ventilation system should be installed in conformance with the appropriate provincial or state requirements or in the absence of such requirements with the current edition of the National Building Code, and / or ASHRAE’s “ Good Engineering Practices”.

HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per hour. To calculate, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35. Example: SQFT of House 1100 Basement 1100 Total SQFT 2200 Height of ceiling x 8 Cubic volume 17600 / 60 Maximum airflow required (CFM) 293 x 0.35 103 * Always consult your local code for sizing requirements in your area. Alternate Method Room classification Number of rooms CFM (L/s) CFM Required Master bedroom x 20 cfm (10 l/s) = if yes add 20 cfm / 10 l/s Basement yes or no = if no = 0 Bedrooms x 10 cfm (5 l/s) = Living room x 10 cfm (5 l/s) = Others x 10 cfm (5 l/s) = Kitchen x 10 cfm (5 l/s) = Bathroom x 10 cfm (5 l/s) = Laundry room x 10 cfm (5 l/s) = x 10 cfm (5 l/s) = Utility room Total Ventilation Requirements (add last column ) = Introducing the NEW Heat Recovery Ventilators (HRV). As with previous designs, incoming fresh outdoor air is filtered before it is heated by the stale outgoing air through a aluminum heat recovery core. The HRV then distributes the preheated fresh filtered air throughout the home by direct ductwork installed specifically for the HRV or through the ductwork of a forced-air system. FEATURES: • Compact Design • Electrostatic Filters (washable) • Airflow Balancing Using Our Easy "TRUE" Motor Adjustment • External Screw Type Dry Contacts For Push Button Timers, Dehumidistat, Crank Timer & Digital Control. • Easy Core Guide Channels For Removing Core • Better Packaging For More Protection In Shipping OPTIONAL CONTROLS • DMFC-REC – Digital Multi-Function Control • MD-4W – Mechanical Low Voltage Dehumidistat with On/Off Switch • MD-2W – Mechanical Low Voltage Dehumi...
