Allowable vent/air pipe materials &
lengths
e concentric termination kit must be purchased sepa-
rately.
Use only the vent materials and kits listed in
Figure21,page17. Provide pipe adapters if
specied.
1. Locate the termination such that the total air piping and
vent piping from the boiler to the termination will not
exceed the maximum length given in Figure20,page16.
2. is termination requires a 45-degree elbow that is not
supplied with the termination kit. e maximum vent/
air pipe lengths include allowance for this elbow.
For polypropylene applications, comply with
any additional requirements in the vent sys-
tem manufacturer’s instructions. (Do Not use
3”PVC transition pieces at the boiler vent and
air connections)and at the termination if using
a 3”PVC concentric vent kit. Install a locking
collar at every joint.
For AL29-4C vent pipe applications, comply
with any additional requirements in the vent
system manufacturer’s instructions. Provide
a AL29-4C starter piece from the AL29-4C
manufacturer to the transition at the boiler
vent connection. Air pipe must be PVC or
CPVC. Provide a 3”PVC transition at the
boiler air connection if using 2” air pipe.
Provide transition pieces to PVC at the vent
and air pipe termination connections.
Determine termination location
Locate the concentric vent/air termination using the fol-
lowing guidelines:
1. e concentric vent/air assembly must terminate as
shown in Figure34,page28.
2. e termination must comply with the clearances and
limitations shown in Figure22,page19.
3. Locate the termination so it is not likely to be damaged
by foreign objects, such as stones or balls, or subject to
buildup of leaves or sediment.
Multiple vent/air terminations
1. When terminating multiple boilers, install the con-
centric vent/air termination assemblies as described in
this manual.
All vent outlets must terminate at the same
height to avoid possibility of severe personal
injury, death or substantial property damage.
2. Place roof penetrations to obtain minimum clear-
ance of 12inches between the edges of adjacent
vent pipes of other boilers for U. S. installations (see
Figure33,page28).
3. e air inlet of a FreeStyle® boiler is part of a direct
vent connection. It is not classied as a forced air in-
take with regard to spacing from adjacent boiler vents.
13 DIRECT VENT — Vertical concentric
Step 1 Read and follow all instructions in this manual. DO NOT
proceed with vent/air installation until you have read
page 15 through page 20.
See notices
at le.
Step 2 Install the boiler in a location that allows proper routing of all
vent and air piping to the selected sidewall location.
Step 3 Make sure the selected vertical termination location complies
with Figure22,page19. (Multiple boiler concentric terminations
must also comply with Figure33,page28.)
Step 4 Use only the vent materials listed in Figure21,page17. Provide
pipe adapters where required.
Step 5 Vent piping and air piping lengths must not exceed the values
shown in Figure20,page16.
Step 6 e concentric termination must be assembled and installed
before piping from the boiler to the termination.
Step 7 Prepare the vertical penetration(s) — assemble the concentric
termination kit and secure the penetration components as
instructed in this section. Provide the supports indicated and
mount the termination assembly. See “Prepare roof penetrations”
on page28 and “Mount concentric termination” on page 28.
See notices at le.
Step 8 Install vent and air piping between the boiler and the concentric
vent/air termination. Slope horizontal piping downward toward
the boiler at least 1/4 inch per foot. See page32 for general
guidelines.
Step 9 Install pipe supports every 5 feet on both the horizontal and
vertical runs.
See notices at le.
Step 10 Install a hanger support within 6inches of any upturn in the
piping.
See notices at le.
USE SWEEP ELBOWS FOR ALL VENT AND
AIR PIPING — DO NOT use short radius elbows
for vent or air piping. Boiler performance could be
aected.
