IMPORTANT: Accessory concentric vent / intake termination kits 1CT0302 and 1CT0303 are available and approved for use with these furnaces. Horizontal sidewall vent terminations kits 1HT0901 & 1HT0902 are also approved for use with these furnaces.

IMPORTANT: Furnace vent pipe connections are sized for 2” (5.1 cm). pipe. Any pipe size change must be made outside the furnace casing in a vertical pipe section to allow proper drainage of condensate. An offset using two 45º (degree) elbows will be required for plenum clearance when the vent is increased to 3” (7.6 cm).

8.Support the combustion air and vent piping such that it is angled a minimum of 1/4” per foot (0.635 cm/m) so that condensate will flow back towards the furnace. Piping should be supported with pipe hangers to prevent sagging.

9.Seal around the openings where the combustion air and / or vent piping pass through the roof or sidewalls.

COMBUSTION AIR / VENT CLEARANCES

IMPORTANT: The vent must be installed with the minimum clearances as shown in Figure 17, and must comply with local codes and require- ments.
