Vent Piping Guidelines

NOTE: 

Allied has approved the use of DuraVent

®

 and 

Centrotherm manufactured vent pipe and terminations as 

an option to PVC. When using the PolyPro

®

 by DuraVent 

or InnoFlue

®

  by  Centrotherm  venting  system  the  vent 

pipe requirements stated in the unit installation instruction 

– minimum & maximum vent lengths, termination 

clearances, etc. – apply and must be followed. Follow 

the instructions provided with PoyPro by DuraVent and 

InnoFlue  by  Centrotherm  venting  system  for  assembly 

or if requirements are more restrictive. The PolyPro by 

Duravent  and  InnoFlue  by  Centrotherm  venting  system 

must also follow the uninsulated and unconditioned space 

criteria listed in Table 13.

The A95DF1E / 95G1DFE can be installed as either a 

Non-Direct Vent or a Direct Vent gas central furnace.

NOTE: 

In Direct Vent installations, combustion air is taken 

from outdoors and flue gases are discharged outdoors. In 

Non-Direct Vent installations, combustion air is taken from 

indoors or ventilated attic or crawlspace and flue gases are 

discharged outdoors.

Intake and exhaust pipe sizing -- Size pipe according to 

Table 10 and Table 11 through Table 12. Count all elbows 

in side and outside the home. Table 10 lists the minimum 

vent pipe lengths permitted. Table 11 through Table 12 lists 

the maximum pipe lengths permitted.

Regardless of the diameter of pipe used, the standard roof 

and wall terminations described in section Exhaust Piping 

Terminations  should  be  used.  Exhaust  vent  termination 

pipe is sized to optimize the velocity of the exhaust gas as 

it exits the termination. Refer to Table 14.

In  some  applications  which  permit  the  use  of  several 

different sizes of vent pipe, a combination vent pipe may 

be used. Contact Allied Technical Services Department for 

assistance in sizing vent pipe in these applications.

NOTE: 

It  is  acceptable  to  use  any  pipe  size  which  fits 

within the guidelines allowed in Table 11 or Table 12.

NOTE: 

All horizontal runs of exhaust pipe must slope back 

toward unit. A minimum of 1/4” (6mm) drop for each 12” 

(305mm) of horizontal run is mandatory for drainage.

NOTE: 

Exhaust pipe MUST be glued to furnace exhaust 

fittings.

NOTE: 

Exhaust piping should be checked carefully to 

make sure there are no sags or low spots.

Capacity

Min. Vent Length*

045, 070, 090, 110

15 ft or 5 ft plus 2 elbows or 

10 ft plus 1 elbow

*Any approved termination may be added to the minimum 

length listed.

Table 10. Minimum Vent Pipe Lengths

Do not use screens or perforated metal in exhaust or 

intake terminations. Doing so will cause freeze-ups and 

may block the terminations.
