MISCELLANEOUS

CONDENSATETRAPANDDRAINSYSTEM(QUALIFIEDSERVICER ONLY)

Annually inspect the drain tubes, drain trap, and field-supplied drain line for proper condensate drainage. Check drain system for hose connection tightness, blockage, and leaks. Clean or repair as necessary.

FLAMESENSOR(QUALIFIEDSERVICERONLY)

Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator causing a drop in the flame sense signal. If the flame sense signal drops too low the furnace will not sense flame and will lock out. The flame sensor should be carefully cleaned by a qualified servicer using emery cloth or steel wool. Following clean- ing, the flame sense signal should be as indicated in the Specifica- tions Sheet.

FLUEPASSAGES(QUALIFIEDSERVICERONLY)

The heat exchanger flue passageways should be inspected at the beginning of each heating season. If necessary, clean the pas- sageways as outlined below.

1.TurnOFFtheelectricalpowerandgassupplytothe furnace.

2.Disconnect the gas line and remove the burner/ manifold assembly by removing the screws securing the assembly to the partition panel.

3.Disconnect the flue pipe system from the induced draft blower.

4.Remove the induced draft blower, drain and pressure tap hoses from the recuperator coil front cover.

5.Remove the recuperator coil front cover to expose the coil tubes and turbulators.

6.Remove the recuperator coil turbulators individually by slowly pulling each turbulator forward firmly.

7.Clean the recuperator coil tubes using a long handle wire brush, such as a gun cleaning brush.

8.Clean the primary heat exchanger tubes using a 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 cable. Slowly rotate the cable with the drill and insert it into one of the heat exchanger tubes. While reversing the drill, work the cable in and out several times to obtain sufficient cleaning. Repeat for each tube.

9.Clean residue from furnace using a vacuum cleaner.

10.Replace the parts removed in the previous steps in reverse order.

11.Turn on electrical power and gas to furnace. Check for leaks and proper unit operation.

12.Severe heat exchanger fouling is an indication of an operational problem. Perform the checks listed in Startup Procedure and Adjustments to reduce the chances of repeated fouling.

BEFORE LEAVING AN INSTALLATION

•Cycle the furnace with the thermostat at least three times. Verify cooling and fan only operation.

•Review the Owner’s Manual with the homeowner and discuss proper furnace operation and maintenance.

•Leave literature packet near furnace.
