Failure to follow this caution may result in incomplete
combustion, flame disturbance, or flame sense lockout.
When installing combustion air and vent system of short pipe
length, the smallest allowable pipe diameter must be used.

NOTE: A 2--in. (51 mm) diameter pipe must be used within
furnace casing. Make all pipe diameter transitions outside furnace
casing per Fig. 40.
2. Unless noted in Table 11, insert perforated disk assembly
(factory--supplied in loose parts bag) in intake housing
where combustion air pipe will be connected. If half disk set
is required, install only shouldered disk half.

connection to combustion air intake housing as shown in
Fig. 38 for application.
2. Reposition combustion air intake housing plug fitting in
appropriate unused intake housing connection.
3. Install combustion--air pipe grommet (factory--supplied in
