However, this reduces the benefits of the ComfortNet system as the enhancements will only apply to the furnace. IMPORTANT NOTE TO THE OWNER REGARDING PRODUCT WARRANTY The modulating furnace operation is based off of negative pressure created by the draft inducer. The furnace control board receives commands from the room thermostat. The furnace control board then controls the RPM of the (3 phase) inducer by varying the frequency and voltage to the inducer. This is known as variable frequency drive (VFD).

LEVELING Leveling ensures proper condensate drainage from the heat exchanger and induced draft blower. For proper flue pipe drainage, the furnace must be level lengthwise from end to end. The furnace should also be level from back to front or have a slight tilt with the access doors downhill (approximately 3/4 inches) from the back panel. The slight tilt allows the heat exchanger condensate, generated in the recuperator coil, to flow forward to the recuperator coil front cover.

This joint can be rotated on the fitting to establish maximum clearance between refrigerant lines, metering devices, and condensate drain lines, etc. This joint is the equivalent of one 90 deg. elbow when considering elbow count. All installations in Canada must conform to the requirements of CAN/CSA B149.1 code.
ALTERNATE FURNACE CONNECTIONS FLANGE If the standard locations are undesirable for a specific installation, alternate side panel locations are available for both combustion air inlet and vent/flue pipe connections on counterflow-horizontal models. On upflow-horizontal models, only an alternate vent location is provided. 3.75" CUT HERE NOTE: Standard and alternate locations can be combined (i.e.

WIRING HARNESS WARNING The wiring harness is an integral part of this furnace. Wires are color coded for identification purposes. Refer to the wiring diagram for wire routings. If any of the original wire as supplied with the furnace must be replaced, it must be replaced with wiring material having a temperature rating of at least 105° C. Any replacement wiring must be a copper conductor.

used for supply and return connections to reduce noise transmission. To prevent the blower from interfering with combustion air or draft when a central return is used, a connecting duct must be installed between the unit and the utility room wall. Never use a room, closet, or alcove as a return air chamber. CHECKING DUCT STATIC Refer to your furnace rating plate for the maximum ESP (external duct static) rating. Total external static refers to everything external to the furnace cabinet.
With a parallel flow arrangement, the dampers or other means used to control the flow of air must be adequate to prevent chilled air from entering the furnace and, if manually operated, must be equipped with means to prevent operation of either unit unless the damper is in the full heat or cool position. Input Airflow UPFLOW COOLING AIRFLOW REQUIREMENT (CFM) When the furnace is installed without a cooling coil, it is recommended that a removable access panel be provided in the supply air plenum.

may require specific quantity of air, consult installation instructions of those devices for requirements. 3. Knowing the furnace model, locate the high stage cooling air flow table. Look up the cooling air flow determined in step 2 and find the required cooling speed and adjustment setting. Example: A *MVM960603BX furnace installed with a 2.5 ton air conditioning system. The air flow needed is 1000 CFM. Looking at the cooling speed chart for *MVM960603BX, find the air flow closest to 1000 CFM.
In general lower heating speeds will: reduce electrical consumption, lower operating sound levels of the blower, and increase the outlet air temperature delivered to the home. The speeds available allow the blower performance to be optimized for the particular needs of the installation. AIRFLOW CONSIDERATIONS Airflow demands are managed differently in a communicating system than they are in a non-communicating wired system.
FOSSIL FUEL APPLICATIONS NOTE: Use of the accessory transformer is recommended if installing a dual fuel/fossil fuel system. Failure to use the transformer in the outdoor unit could result in over loading of the furnace transformer. This furnace can be used in conjunction with a ComfortNet™ compatible heat pump in a fossil fuel application.

The burner flames should be inspected with the burner compartment door installed. Flames should be stable, quiet, soft, and blue (dust may cause orange tips but they must not be yellow). Flames should extend directly outward from the burners without curling, floating, or lifting off.
PRESSURESWITCHES DIAGNOSTIC CHART The pressure switches are normally-open (closed during operation) negative air pressure-activated switches. They monitor the airflow (combustion air and flue products) through the heat exchanger via pressure taps located on the induced draft blower and the coil front cover. These switches guard against insufficient airflow (combustion air and flue products) through the heat exchanger and/or blocked condensate drain conditions.
ANNUALINSPECTION HORIZONTAL UNIT FILTER REMOVAL The furnace should be inspected by a qualified installer, or service agency at least once per year. This check should be performed at the beginning of the heating season. This will ensure that all furnace components are in proper working order and that the heating system functions appropriately. Pay particular attention to the following items. Repair or service as necessary.
