11 - INSTALLATION - CATEGORY IV: Vent and combustion air

11.1 - CATEGORY
IV: Positive
pressure
condensing
An appliance that operates with a
positive vent static pressure with a
vent gas temperature that may cause
condensate production in the vent.
11.2 - CATEGORY
IV: 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!
WARNING!!!
All vent pipes
must be mechanically fixed.
Improper venting can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!
WARNING!!!
The
horizontal and vertical 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 fixed
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!
NOTICE! The exhaust pipe must be
pitched a minimum of a 1/4 inch per
foot back to the appliance (to allow
drainage of condensate).
NOTICE! The venting system
shall be installed with a means for
condensate disposal in order to
prevent its accumulation.
NOTICE! Due to the high efficiency of
the appliance 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.
This appliance requires a special vent
system, designed for pressurized
venting.
You must install air piping from
outside to the appliance air intake.
The resultant installation is Direct Vent
(sealed combustion).
The appliance is to be used for
either Direct Vent installation or for
installation using room combustion
air. When room air is considered, see
Section 11.9.
Vent and air must terminate near one
another and may be vented vertically
through the roof or out a side wall,
unless otherwise specified. You may
use any of the vent/air piping methods
from Figure 11-1 to Figure 11-6. Do
not attempt to install this appliance
using any other means.
WARNING!!!
DO NOT mix
components from different
systems. The vent system
could fail, causing leakage of
flue products into the living
space. Use only approved
materials listed on Figures 11-7
and 11-8. Improper materials
or mixing materials can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!

WARNING!!!
Use of
cellular core PVC and CPVC
or Radel for venting system is
not allowed. Use of improper
materials can result in
excessive levels of carbon
monoxide which can result
in severe personal injury or
death!
Be sure to locate the appliance 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 11.3.
