4. Operational Check:

cCAUTION: Before troubleshooting, familiarize yourself with the start up and check out procedures

NOTICE: After reassembling the appliance, check for fuel oil leakage from the supply piping.

a.Check proper operation of the ignition system and for proper combustion.

b.Observe the main burner flame. If the flame appears strange or abnormal in character, look for a component or components that were not reassembled correctly. If the components have been reassembled correctly, check for a blocked vent, malfunctioning combustion air blower or fuel pump, and partially blocked burner nozzle.

D. ELECTRICAL SYSTEM:

cWARNING: When servicing controls, label all wires prior to disconnecting. Correctly reconnect any wires removed during servicing. Wiring errors can cause improper and dangerous operation. Dangerous operation can result in injury or damage.

1.Check all wiring for loose connections and any signs of damage, or unusual wear. Replace any damaged or frayed wiring and tighten any loose connections.

2.Use a voltmeter, or a multimeter, to check for adequate voltage at the field connections when the appliance operating.

3.Use an ammeter, or a multimeter, to check the current draws of the blower motor and burner assembly, to assure they are not exceeding rating label current specifications for each component. Also, refer to Table 10 in the electrical wiring section of this manual for electrical specifications on these components.

4.Check for correct operation and proper settings (if manually adjustable) of all controls.

E. SUPPLY/RETURN AIR BLOWER:

Check in the blower compartment for dust, dirt, debris, and for the presence of insects. Remove any foreign material. Clean the blower wheel, housing, and compartment of dust and lint with a vacuum.

The blower motor has sealed bearings that are permanently lubricated. The blower motor bearings do

not require oil or any type of additional lubrication.

F. SUPPLY/RETURN AIR FILTER:

A permanent-type air filter is provided in the return section of this unit. This filter should be inspected regularly. When the filter is dirty, it should be cleaned or replaced to assure proper heating/cooling system operation. Follow the cleaning, removal and replacement procedure below.

Filter maintenance procedure:

Shut off the electrical power to the unit. The filter rack is located above the blower refer to Figure 26 on the next page. Remove the front door of the furnace. Remove the (2) screws retaining the right blower access door to the housing. Remove the access door. Slide the air filter out of the filter rack. Clean the filter by either vacuuming, rinsing with tap water, hosing, or dipping in an ordinary detergent solution. After cleaning and drying the filter, replace the completely dry filter in the rack. If the filter has a supporting mesh, the mesh side of the filter must be placed towards the furnace. Replace the right blower access door and the front door before turning the electrical power back on to the furnace.
