Important Information Concerning Altitude Impact on Heating Input Ratings Heating input, and thus heating output, decreases with altitude. No orifice change is required up to 6, feet elevation and derate occurs naturally due to altitude impact. Natural gas models may require orifice change based on BTU content of gas. See Natural Gas Orifice and Altitude Tables on next page for details. For Propane Gas see the Propane Gas Conversion Table below. Above 6, feet elevation orifice changes are required, and capacity reductions are a function of altitude impact and orifice change. Pressure switch change is required above 6, feet elevation. For Natural Gas see the Orifice and Altitude Tables on next page. For Propane Gas see the Propane Gas Conversion Table below.

Ventilation System Packages Bard Wall-Mounts are designed to provide optional ventilation packages to meet all of your ventilation and indoor air quality requirements. All units are equipped with a barometric fresh air damper as the standard ventilation package. All ventilation packages can be built-in at the factory, or field-installed at a later date. BAROMETRIC FRESH AIR DAMPER - WGBFAD STANDARD The barometric fresh air damper is a standard feature on all models. It is installed on the inside of the service door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The damper opens during blower operation and closes when the blower is off. Adjustable blade stops allow different amounts of outside air to be introduced into the building and can be easily locked closed if required. BAROMETRIC FRESH AIR DAMPER BLANK OFF PLATE - WGBOP OPTIONAL A blank off plate is installed on the inside of the service door. It covers the air inlet openings which restricts any outside air from entering the unit. The blank off plate should be utilized in applications where outside air is not required to be mixed with the conditioned air. MOTORIZED FRESH AIR DAMPER - WGMFAD OPTIONAL The motorized fresh air damper is internally mounted behind the service door and allows outside ventilation air, up to 25% of the total airflow rating of the unit, to be introduced through the air inlet openings and to be mixed with the conditioned air. The two position damper can be fully open or closed. The damper blade is powered open by a 24VAC motor with spring return on power loss. The damper can be controlled by indoor blower operation or can be field connected to be managed based on building occupancy. MOTORIZED FRESH AIR DAMPER NOTE: The above vent systems are intake only without built-in exhaust capability. Building will likely require separate field installed barometric relief or mechanical exhaust elsewhere within the conditioned space. Balancing dampers in the return air grille may be required to achieve specified amount of outdoor air intake. COMMERCIAL ROOM VENTILATOR - WGCRV OPTIONAL The built-in commercial room ventilator is internally mounted behind the service door and allows outside ventilation air, up to 5% of the total airflow rating of the unit, to be introduced through the air inlet openings. It includes a built-in exhaust air damper. The commercial room ventilator (WGCRV) is a simple and innovative approach to improving the indoor air quality by providing fresh air intake and exhaust capability through the WGCRV. The damper can be easily adjusted to control the amount of fresh air supplied into the building. The WGCRV can be controlled by indoor blower operation or field controlled based on room occupancy. Complies with ANSI/ASHRAE Standard 62.1 Ventilation for Acceptable Indoor Air Quality. COMMERCIAL ROOM VENTILATOR Two Models Available: WGCRVS - spring return on power loss or deactivation WGCRVP - power return (will not close on power loss) ECONOMIZER - WGJIFM OPTIONAL The built-in economizer system is internally mounted behind the service door and allows outdoor air to be introduced through the air inlet openings. The amount of outdoor air varies in response to the system controls and settings defined by the end user. It includes a built-in exhaust air damper. The economizer is designed to provide free cooling when outside air conditions are cool and dry enough to satisfy cooling requirements without running the compressor. This in turn provides lower operating costs, while extending the life of the compressor. ECONOMIZER Standard Features: One Piece Construction - Easy to install with no mechanical linkage adjustment required. Exhaust Air Damper - Built in with positive closed position. Provides exhaust air capability to prevent pressurization of tight buildings. Actuator Motor - 24 volt, power open, spring return with built in torque limiting switch. Proportioning Type Control - for maximum free cooling economy and comfort. Moisture Eliminator & Prefilter - permanent, washable aluminum construction. Enthalpy Control - adjustable to monitor outdoor temperature and humidity. Honeywell JADE electronic economizer module with precision settings and diagnostics. Mixed Air Sensor - to monitor outside and return air to automatically modulate damper position. WALL-MOUNT ENERGY RECOVERY VENTILATOR - WGERV OPTIONAL The wall-mount energy recovery ventilator (WGERV) is a highly innovative approach to address indoor air quality ventilation requirements as established by ANSI/ASHRAE Standard 62.1. The WGERV allows up to 45 CFM (depending upon speed setting) of fresh air and exhaust through the unit while maintaining superior indoor comfort and humidity levels. In most cases this can be accomplished without increasing equipment sizing or operating costs. Heat transfer efficiency is up to 74% during summer and % during winter conditions. ENERGY RECOVERY VENTILATOR The WGERV consists of a unique rotary energy recovery cassette that provides effective sensible and latent heat transfer capabilities during summer and winter conditions. Various control schemes are addressed including limiting ventilation during building occupancy only. The WGERV is designed to be internally mounted behind the service door in the WG Gas/Electric units. It can be builtin at the factory or field installed as an option. WGERV can be independently adjusted for intake and exhaust rates. NOTE: See Page 8 for WGERV Performance Data and Page 9 for WGCRV Performance Data Page 7 of 14

Compressor control module has adjustable 3-second to 5-minute delay-on-break timer. On initial power-up, or any time the power is interrupted, the delay-on-make will be 2-minutes plus 1% of the delay-on-break setting. There is no delay-on-make during routine operation of the unit. The module also provides the lockout feature (with 1 retry) for high and/or low-pressure controls, and a 2-minute timed bypass for low-pressure control. HPC. High pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. LPC. Low pressure control is auto reset. Always used with compressor control module (CCM) which is included. See note. LAC. Low ambient control permits cooling operation down to F.
