22 ! W ARNING: Ensure that the combustion air vent and the exhaust vent are confi gured as shown in Figure 19 and 20. Improper vent termination can cause recir- culation of the fl ue gases. This may result in furnace vibration. In severe cases, the furnace will cyc le due to the intermittent contact between the fl ame and the fl ame sensor .

26 V ent and combustion air piping ma y be installed in an e xisting chimney which is not in use pro- vided that: a. Both the e xhaust vent and air intak e r un the length of the chimney . b . The top of the chimne y is sealed and weatherproofed. c. The ter mination clearances shown in Figure 23 are maintained.
27 Concentric V ent T er mination Concentric vent termination kits are approv ed f or use with these fur naces. The kit par t numbers are 904176 (3 inch) and 904177 (2 inch). For proper installation of the concentric vent termina- tion, f ollow the installation instructions provided with that kit.
28 NO TE: Industr y research studies indicate that when condensate is routed to an activ e drain, household detergents, etc., b uffer its acidity . If the drain is not activ ely used or if codes require, obtain a neutraliz er kit (usually contains lime- stone).

32 T o check the heat anticipator setting either : 1. Add the current draw of the system compo- nents; or 2. Measure the current fl ow on the thermostat R-W circuit after the circulating blo wer motor has star ted. Set the heat anticipator according to the ther- mostat manuf acturer’ s instr uctions f or heat anticipator settings.
33 6. Adjustments to the fi r ing rate can be made by adjusting the gas manif old pressure. See the High Altitude Application section f or additional information of fi r ing rate at ele vations abov e 2000 ft. The manif old pressure must be set to the ap- propriate value f or your installation.
