HRV200PLUS INSTALLATION INSTRUCTIONS D. DEFROST OPTIONS The HRV200PLUS performs as a whole house heat recovery ventilator during Fresh Air Fireplace operation and continuous ventilation operation. When the Fresh Air Fireplace is in use, the HRV core temperature is elevated with no chance of frost or ice build-up at any time. However, when the HRV200PLUS is operating in continuous ventilation mode, outdoor temperatures below 25°F can cause frost to form on the core.

HRV200PLUS INSTALLATION INSTRUCTIONS 1. Location F. INSTALLING THE VENTILATOR The HRV200PLUS must be located in a heated space where it will be possible to conveniently service the ventilator. Typically the HRV200PLUS would be located in the mechanical room or an area close to the outside wall where the weather hoods will be mounted. If a basement area is not convenient, a utility or laundry room may be used. Attic installations are not normally recommended due to: a. The complexity of work to install.
HRV200PLUS INSTALLATION INSTRUCTIONS G.
HRV200PLUS INSTALLATION INSTRUCTIONS b. Install Fresh Air Supply Ducting The inner and outer liners of the insulated duct must be clamped to the sleeve of the weatherhood as close to the outside as possible and to the plastic inlet port on the HRV200PLUS. It is very important that the fresh air intake line be given special attention to make sure it is well sealed.
HRV200PLUS INSTALLATION INSTRUCTIONS Note: When using the existing furnace duct work for air distribu- tion, the furnace blower must be set to run continuously or interlocked with the HRV200PLUS. The interlock may be easily achieved using the Furnace Interface Relay terminals on the HRV200PLUS control board. These terminals interface directly with the furnace control board using low voltage wiring. See wiring diagram in Section L. WIRING for details. b.

HRV200PLUS INSTALLATION INSTRUCTIONS WARNING - RISK OF FIRE! Always maintain minimum clearances or greater around the vent system. Do not pack air spaces with insulation or other material. The flow of combustion and ventilation air must not be obstructed. 5. Firestop Spacer/Vent Installation Following code requirements, frame an opening and install a firestop spacer whenever the vent penetrates a ceiling, wall or floor area, as shown in Figure 13.

HRV200PLUS INSTALLATION INSTRUCTIONS J. BALANCING 1. Balancing Collar Instructions WARNING! Risk of carbon monoxide! Negative air pressure may cause back drafting of gas appliances. Proper balancing of the HRV is required. Figure 14 2. Air Flow Balancing Æ Note: When installing the Caliber NXT Plus or 6100 PLUS with the HRV200PLUS, a minimum of 130 CFM must be maintained for fireplace operation.
HRV200PLUS INSTALLATION INSTRUCTIONS 3. Pitot Tube Balancing Procedure (see Figure 16) The following is a method of field balancing an HRV200PLUS using a pitot tube, advantageous in situations when flow stations are not installed in the duct work. The procedure should be performed with the HRV200PLUS on high speed. The first step is to operate all mechanical systems that have an influence on the ventilation system (i.e. the HRV itself and the forced air furnace or air handler if applicable) on high speed.

HRV200PLUS INSTALLATION INSTRUCTIONS M. MAINTENANCE INSTRUCTIONS Proper maintenance is critical to the proper operation of the HRV200PLUS. The following schedule should be followed: 1. Monthly Maintenance - Inspect Exterior Hoods Make sure exhaust and fresh air supply hoods are not blocked or restricted by leaves, grass, or snow. In winter, it is especially important to make sure snow is not blocking the hoods or that frost has not built up on the wire mesh (bird screen).
HRV200PLUS INSTALLATION INSTRUCTIONS 4. Annual Maintenance a. Inspect and Clean Drain (condensate) Lines (if required) Inspect the drain line, drain spout and P-trap for blockage, mold or kinks. Flush with warm soapy water. Replace if worn, bent or if you are unable to clean. b. Inspect and Clean Duct Work (if required) The duct work running to and from the HRV200PLUS may accumulate dirt. Wipe and vacuum the duct once every year. You may wish to contact a heating/ventilation company to do this. c.
HRV200PLUS INSTALLATION INSTRUCTIONS N. LED DIAGNOSTICS The HRV200PLUS comes equipped with a diagnostic LED mounted in the right side of the cabinet just below the power cord. This LED indicates the state of the HRV - both normal operating modes as well as abnormal fault conditions.
