10.3 - Venting and
air piping systems
WARNING!!!
The vent
installation must be in
accordance with part Venting
of Appliances, of the latest
edition of the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or
section, Venting Systems and
Air Supply for Appliances, of
the CAN/CSA B149.1, Natural
Gas and Propane Installation
code or applicable provisions
of the local building codes.
Improper venting can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!
NOTICE! All vent pipes must
be mechanically fi xed, properly
supported, and the exhaust must
be pitched a minimum of a 1/4 inch
per foot back to the boiler (to allow
drainage of condensate).
NOTICE! The vent system shall
be installed so as to prevent the
accumulation of condensate.
NOTICE! Due to the high effi ciency of
the boiler it may discharge what looks
like white smoke especially when the
outside air temperature is cold. This is
a simply water vapor, a purely natural
phenomenon and not a reason for
concern.
WARNING!!!
The exhaust
vent and the air inlet lines,
must be supported to prevent
sagging. To do this, use a
suitable pipe clamp to support
the lines. Pipe clamps shall
support the line every 3 ft (1
m). Pipe clamp shall be fi xed
in correspondance of a wall
stud. Improper supporting can
result in excessive levels of
carbon monoxide which can
result in severe personal injury
or death!
This boiler requires a special vent
system, designed for pressurized
venting.
You must install air piping from
outside to the boiler air intake. The
resultant installation is Direct Vent
(sealed combustion).
The boiler is to be used for either
Direct Vent installation or for
installation using room combustion
air. When room air is considered, see
Section 10-10.
Vent and air must terminate near one
another and may be vented vertically
through the roof or out a side wall,
unless otherwise specifi ed. You may
use any of the vent/air piping methods
from Figure 10-1 to Figure 10-6. Do
not attempt to install this boiler using
any other means.
WARNING!!!
DO NOT mix
components from different
systems. The vent system
could fail, causing leakage of
fl ue products into the living
space. Use only approved
materials listed on Tables 10-1
and 10-2. Improper materials
or mixing materials can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!
Be sure to locate the boiler such that
the vent and air piping can be routed
through the building and properly
terminated.
The vent/air piping lengths, routing
and termination method must all
comply with the methods and limits
given in Section 10.4
10 - INSTALLATION - Vent and combustion air
10.2 - Prevent
combustion air
contamination
Install air inlet piping as described
in this Section 10. You must pipe
combustion air to the boiler air intake.
Do not terminate vent/air in locations
that can allow contamination of
combustion air.
WARNING!!!
Contaminate
combustion air will damage
the boiler, resulting in possible
severe personal injury, death or
substantial property damage.
Ensure that the combustion air
will not contain any of the follow
contaminants.
Products that may contaminated the
air combustion:
- Permanent wave solutions;
- Chlorinated waxes/cleaners;
- Chlorine-based swimming pool
chemicals;
- Calcium chloride used for thawing;
- Sodium chloride used for water
softening;
- Refrigerant leaks;
- Paint or varnish removers;
- Hydrochloric acid/muriatic acid;
- Cements and glues;
- Antistatic fabric softeners used in
clothes dryers;
- Chlorine-type bleaches, detergents,
and cleaning solvents found in
household laundry rooms;
- Adhesives used to fasten building
products and other similar products;
Do not pipe combustion air near
sources of products that may
contaminate the air combustion, like:
-Dry cleaning/laundry areas and
establishments;
- Swimming pools;
- Metal fabrication plants;
- Beauty shops;
- Refrigeration repair shops;
- Photo processing plants;
- Auto body shops;
- Plastic manufacturing plants;
- Furniture refi nishing areas and
establishments;
- Remodeling areas;
- Garages with workshops.
