VENTING & AIR INLET PIPING
D. EXHAUST VENT/AIR INTAKE PIPE SIZING
1. PureFire boiler model PFW-199 and PF-210 are to be
installed using 3” Schedule 40 or 80 PVC or CPVC
piping using the provided vent adapter. PureFire boiler
model PFW-399 is to be installed using Schedule 40 or
80 PVC or CPVC using the vent adapter provided.
2. Polypropylene vent systems may be installed using
optional InnoFlue
®
or PolyPro
®
vent adapters. Table
3.2 shows the appropriate PB Heat stock codes.
Contact your PB Heat Representative for more
information on this option.
3. Combined systems using separate polypropylene
exhaust & air inlet pipes which transition to concentric
can also be installed. Contact your Centrotherm or
DuraVent representative for more information.
4. The total combined length of exhaust vent and air
intake piping is 200 equivalent feet (60 m).
a. The equivalent length of elbows, tees and other
fittings are listed in Table 3.3.
b. The equivalent length can be calculated as follows.
This is well below the 200 feet maximum
equivalent length. If the total is above 200
equivalent feet, alternate boiler locations or
exhaust penetration location should be considered.
