Page 5: Gas Supply Piping And Connections
In furnace modules with bottom mounted horizontal burner, condensate will drain from the open end of the tubes. A condensate collection pan which attaches to the burner assembly is available as an option. Additionally, condensation typically forms on exterior surfaces, such as the furnace vestibule panel (header plate), in contact with the conditioned air. -

Page 14: Safety And Ignition Controls
Operating & Safety Controls Combustion Air Pressure Switch An air pressure switch is provided as part of the control system to verify airflow through induced draft fan (ID fan) by monitoring the difference in pressure between the ID Fan and the atmosphere. If sufficient negative pressure is not present, indicating lack of proper air movement through heat exchanger, the switch opens shutting off gas supply though the ignition control module. - Page 15 Annual Furnace Inspection 1. The duct furnace should be inspected annually by a qualified service agency. The condition of the burners, heat exchanger, draft inducer, vent system, operating controls and wiring should be determined. Check for obvious signs of deterioration, accumulation of dirt and debris and any heat or water related damage. Any damaged or deteriorated parts should be replaced before the unit is put back into service.
