To change filter with a front load type drop chute, follow the instructions for an upflow furnace. To change filters using the V-rack, remove the furnace front door and remove the filters through the blower opening (or in the event access slots are provided in the plenum, pull the filters directly out through these slots). Clean filters by vacuuming, tap water rinsing, hosing or dipping in an ordinary detergent solution. After cleaning, replace completely dry filter, mesh side down on the filter rack on the top of the furnace. Replace front door. Turn on power to furnace. 12 All installations and services must be performed by qualified service personnel. Figure 4. FILTER REPLACEMENT See Table 1 for minimum heating filter areas required for the different types of filters available should the filter used require replacement. If the unit is equipped with cooling, contact your installer or a qualified service person to determine the minimum filter area required for the different filter types and your cooling system. 13 All installations and services must be performed by qualified service personnel.

Turn off power to furnace. 2. Vent pipe, air intake pipe, and condensate system (CDB1/CHB1, CDX1/CHX1): Visually check the vent and intake pipe as well as condensate lines both inside and outside the furnace to make sure that vent intake joints and the condensate system are sealed. There should be no sign of water leakage at any vent intake or condensate joints or anywhere inside the furnace. Make sure that horizontal runs of vent pipe slope upward towards the outside. The inlet pipe should slope slightly downward to prevent condensate build up. Any signs of damage, leakage, deterioration, or possible blockage should be immediately reported to your dealer or the local gas company.
