VENTING & AIR INLET PIPING
A. GENERAL
1. Install the P
ure
F
ire
®
boiler venting system in
accordance with these instructions and with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, CAN/CGA
B149, and/or applicable provisions of local building
codes.
2. The P
ure
F
ire
®
boiler is approved for positive
pressure exhaust venting using either indoor air or
air piped from outside. It is ETL Listed as a Category
IV (Positive Pressure, Condensing Exhaust Vent)
Appliance.
B. APPROVED MATERIALS
1. Table 3.1 lists approved materials for vent pipe (and
adhesives where applicable). Use only these materials
for exhaust vent piping.
2. PVC Pipe and fittings are not to be used for exhaust
venting in confined spaces such as closet or alcove
installations or vent pipe that passes through attics.
3. Table 3.2 lists appropriate materials for air inlet
piping. Air inlet piping is to be sealed suitably to
prevent introduction of dirt, chemicals or other
contaminants to the inlet air stream.
4. Use of cellular core PVC (ASTM F891), cellular core
CPVC, or Radel
®
(polyphenolsulfone) in venting
systems shall be prohibited. Covering non-metallic
vent pipe and fittings with thermal insulation shall be
prohibited.
* PVC pipe/fittings are not to be used for venting within
confined spaces.
Notice: Installations in Canada require compliance with
ULC S636 - Standard for Type BH Gas Venting Systems.
C. EXHAUST VENT/AIR INTAKE PIPE
LOCATION
1. Install vent piping before installing water, fuel,
or condensate piping. Working from largest to
smallest diameter reduces the complexity of piping
interferences.
2. Vent and air intake piping is to be installed so that
there is sufficient access for routine inspection as
required in Section 11, of this manual.
3. The vent piping for this boiler is approved for zero
clearance to combustible construction. However, a
fire stop must be used where the vent pipe penetrates
walls or ceilings.
3. VENTING & AIR INLET PIPING
The venting system for this product is to be installed
in strict accordance with these venting instructions.
Failure to install the vent system properly may result in
severe personal injury, death or major property damage.
WARNING
This vent system operates under positive pressure.
Vent connectors serving appliances vented by
natural draft shall not be connected into any portion
of this venting system. Failure to comply may result
in serious injury, death or major property damage.
WARNING
Only the materials listed below are approved for use
with the
P
ure
F
ire ® boiler. Use only these components
in accordance with these instructions. Failure to
use the correct material may result in serious injury,
death, or major property damage.
WARNING
This appliance uses a positive pressure venting
system. All joins must be sealed completely to
prevent leakage of flue products into occupied
spaces. Failure to do this may result in severe
personal injury, death or major property damage.
WARNING
Use of cellular core pipe for any exhaust vent
component is prohibited. Use of cellular core pipe
may result in severe personal injury, death, or major
property damage.
