7.IMPORTANT: Replace all blower doors and compartment cover after servicing the unit. Do not operate the unit without all panels and doors securely in place.

8.Do not allow snow or other debris to accumulate in the vicinity of the appliance.

FURNACE SECTION MAINTENANCE

The unit’s furnace should operate for many years without excessive scale build-up in flue passageways; however, it is recommended that a qualified installer, service agency, or the gas supplier annually inspect the flue passageways, the exhaust system and the burners for continued safe operation, paying particular attention to deterioration from corrosion or other sources.

If during inspection the flue passageways and exhaust system are determined to require cleaning, the following procedures should be followed (by a qualified installer, service

agency, or gas supplier):

1.Turn off the electrical power to the unit and set the thermostat to the lowest temperature.

2.Shut off the gas supply to the unit either at the meter or at manual valve in the supply piping.

!WARNING

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION RESULTING IN FIRE, ELECTRICAL SHOCK, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

3.Remove the furnace controls access panel and the control box cover.

4.Disconnect the gas supply piping from the gas valve.

5.Disconnect the wiring to the induced draft blower motor, gas valve, flame sensor, and flame roll-out control, and ignitor cable. Mark all wires disconnected for proper reconnection.

6.Remove the screws (4) connecting the burner tray to the heat exchanger mounting panel.

7.Remove the burner tray and the manifold assembly from the unit.

8.Remove the screws (5) connecting the induced draft blower to the collector box and screws (18) connecting the collector box to the heat exchanger center panel. Remove the induced draft blower and the collector box from the unit.

9.Remove the screws (3) connecting the divider plate to the heat exchanger center panel.

10.Remove the turbulators from inside the heat exchangers by inserting the blade of a screwdriver under the locking tabs. Pop the tabs out of the expanded grooves of the heat exchanger. Slide the turbulators out of the heat exchangers.

11.Direct a water hose into the outlet of the heat exchanger top. Flush the inside of each heat exchanger tube with water. Blow out each tube with air to remove excessive moisture.

12.Reassemble (steps 1 through 10 in reverse order). Be careful not to strip out the screw holes used to mount the collector box and inducer blower. Replace inducer blower gasket and collector box gasket with factory replacements if damaged.

!WARNING

HOLES IN THE EXHAUST TRANSITION OR HEAT EXCHANGER CAN CAUSE TOXIC FUMES TO ENTER THE HOME. THE EXHAUST TRANSITION OR HEAT EXCHANGER MUST BE REPLACED IF THEY HAVE HOLES OR CRACKS IN THEM. FAILURE TO DO SO CAN CAUSE CARBON MONOXIDE POISONING RESULTING IN PERSONAL INJURY OR DEATH.

The manufacturer recommends that a qualified installer, service agency or the gas suppli- er visually inspect the burner flames for the desired flame appearance at the beginning of the heating season and approximately midway in heating season.

The manufacturer also recommends that a qualified installer, service agency or the gas supplier clean the flame sensor with steel wool at the beginning of the heating season.

A-13 specifications

The Heat Controller A-13 is an innovative and efficient heating solution designed to provide optimal comfort while reducing energy consumption. This advanced unit stands out in the market due to its combination of cutting-edge technologies and user-centric features, making it an ideal choice for both residential and commercial applications.

One of the main features of the A-13 is its high energy efficiency rating. With a SEER (Seasonal Energy Efficiency Ratio) rating of up to 23, the unit not only lowers energy bills but also minimizes the carbon footprint, making it an environmentally friendly option. This efficiency is further enhanced by the use of variable speed inverter technology, which allows the unit to modulate its output based on the specific heating demand. This ensures a more consistent and comfortable indoor environment while avoiding the energy wastage associated with traditional fixed-speed systems.

The A-13 incorporates state-of-the-art smart technology, enabling users to control their heating system remotely. Through a dedicated mobile application, homeowners can adjust settings, monitor energy consumption, and receive maintenance alerts directly from their smartphones. This level of control offers convenience and ensures that the space is always comfortable upon arrival.

In addition to smart capabilities, the A-13 is designed with ultra-quiet operation in mind. Thanks to its advanced compressor and fan technology, the unit operates at sound levels as low as 26 decibels, ensuring a peaceful atmosphere even when the heating system is in operation. This is particularly beneficial for environments where noise can be a distraction, such as bedrooms or offices.

The heat exchanger technology used in the A-13 further contributes to its high performance. The unit features a corrosion-resistant, gold-fin coating that enhances durability and heat transfer efficiency. This not only extends the lifespan of the unit but also helps maintain optimal performance over time.

Safety features are also a priority in the A-13 design. The unit includes multiple safety mechanisms, such as overheating protection and automatic shut-off functions, ensuring safe operation even during extended use.

Overall, the Heat Controller A-13 represents a blend of efficiency, performance, and user-friendly technology, making it a top choice for those seeking reliable and sustainable heating solutions in their spaces. With its combination of smart controls, quiet operation, and robust safety features, the A-13 is indeed a leader in modern heating solutions.
