Amana VR8205 installation instructions Furnace mounted Filter Rack Counterflow

Page 28

The furnace-mounted filter rack includes a rack mounted on the top of the furnace. Two filters fit into the rack and rest against the sides of the return air plenum, forming a “V” above the furnace.

The filters should be inspected frequently and cleaned or replaced when necessary. In some installations, the filters can be inspected after disconnecting the electrical power and removing the optional access door in the return air plenum. If this access panel is not present, proceed as follows:

1.Disconnect the electrical power.

2.Remove the non-louvered door from the furnace.

3.Remove the left filter by reaching to the left side of the blower, pushing the filter up slightly to remove it from the filter rack, and pulling it down to the left of the blower and out the blower door. Repeat with the right filter.

4a. Dirty throwaway filters must be replaced with the same filter type and size.

4b. Dirty, permanent metal filters must be cleaned as follows:

Wash, rinse, and dry the permanent filters. Both sides should then be sprayed with a filter adhesive as is recommended on the adhesive container. Many hard- ware stores stock spray adhesives for use with perma- nent filters.

If badly torn or uncleanable, these filters must be replaced by equal size permanent, high velocity filters. Throwaway filters must not be used as replacement for permanent filters. Under normal use, permanent filters should last for several years.

5.To reinstall the filters, first MAKE CERTAIN THE AIRFLOW DIRECTION ARROW POINTS TOWARDS THE FURNACE. Then insert the filters from the left side of the blower. Starting with the right filter, push the filter into the plenum so that the bottom of the filter rests in the filter rack and the upper edge rests against the side of the plenum. Repeat with the left filter (Figure 44).

6.Replace the blower door, then reconnect the electrical power.

BLOWER MOTOR

The air circulating blower motor bearings are permanently lubricated. No further lubrication is required.

INDUCED DRAFT BLOWER MOTOR

The induced draft blower motor is permanently lubricated. No further lubrication is required.

FLAME SENSOR (INTEGRATED IGNITION CONTROL) (QUALIFIED SERVICER ONLY)

The fuel or combustion air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator, causing a drop in the flame sensing signal. To remove this coating, a qualified servicer should carefully clean the flame sensor with emery cloth or steel wool. After cleaning, the microamp signal should be in the range listed in Specification Sheet.

IGNITOR (QUALIFIED SERVICER ONLY)

If the ignitor and the surrounding air are at about 70°F and the ignitor wires are not connected to any other electrical components, the resistance of the ignitor should not ex- ceed 200 ohms. If it does, the ignitor should be replaced.

FLUE PASSAGES (QUALIFIED SERVICER ONLY)

At the start of each heating season, inspect and if nec- essary, clean the furnace flue passages.

CLEANING FLUE PASSAGES (QUALIFIED SERVICER ONLY)

1.Shut off electric power and gas supply to the furnace.

2.Remove burner assembly by disconnecting the gas line and removing the manifold brackets from the partition panel.

3.Remove the flue from the induced draft blower and the collector box from the partition panel.

4.The primary heat exchanger tubes can be cleaned using a round wire brush attached to a length of high grade stainless steel cable, such as drain cleanout cable. Attach a variable speed reversible drill to the other end of the spring cable. Slowly rotate the cable with the drill and insert it into one of the primary heat exchanger tubes. While reversing the drill, work the cable in and out several times to obtain sufficient cleaning. Use a large cable for the large tube, and then repeat the operation with a small cable for the smaller tube. Repeat for each tube.

5.When all heat exchanger tubes have been cleaned, replace the parts in the reverse order in which they were removed.

6.To reduce the chances of repeated fouling of the heat exchanger, perform the steps listed in Section X, Start- up, Adjustments, and Checks.
