Single Pipe Vent (Not Sealed Combustion) - RBI Infinite Energy2 IW199 Installation And Operation Instructions Manual

11 - INSTALLATION - CATEGORY IV: Vent and combustion air
11.9 - Single pipe
vent (not sealed
combustion)
For appliances for connection to gas
vents or chimneys, vent installations
shall be in accordance with "Venting of
Equipment," of the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, or "Venting
Systems and Air Supply for Appliances,"
of the Natural Gas and Propane
Installation Code, CAN/CSA B149.1, or
applicable provisions of the local building
codes.
WARNING!!!
When utilizing
the single pipe vent method,
provisions for combustion
and ventilation air must be
in accordance with Air for
Combustion and Ventilation, of
the latest edition of the National
Fuel Gas Code, ANSI Z223.1,
in Canada, the latest edition of
CGA Standard B149 Installation
Code for Gas Burning Appliances
and Equipment, or applicable
provisions of the local building
codes (see Section 5.1).
Failure to follow this warning
could result in excessive levels of
carbon monoxide, wich can cause
sever personal injury or death!
Commercial applications utilizing this
appliance may be installed with a
single pipe carrying the flue products
to the outside while using combustion
air from the equipment room. In this
case the following conditions and
considerations must be followed.
NOTICE! There will be a noticeable
increase in the noise level during
normal operation from the inlet air
opening.
NOTICE! Vent system and terminations
must comply with the venting
instructions set forth in Sections
11.6, 11.7 and 11.8.
WARNING!!!
Use only
the materials, vent systems, and
terminations listed in Figures
11-7 and 11-8. DO NOT mix vent
systems of different types or
manufacturers, unless listed in this
manual. Failure to comply could
result in severe personal injury,
death, or substantial property
damage.
WARNING!!!
Fire danger
due to flammable materials or
liquids. Do not store flammable
materials and liquids in the
immediate vicinity of the
appliance.
WARNING!!!
Appliance
must be clear and free from
combustible materials, gasoline
and other flammable vapors and
liquids, and corrosive liquids and
vapors. Never use chlorine and
hydrocarbon containing chemicals
(such as spray chemicals, solution
and cleaning agents, paints,
glues etc.) in the vicinity of the
appliance. Do not store and use
these chemicals in the appliance
room. Avoid excessive dust
formation and build-up. Failure
to comply could result in fire,
severe personal injury, death, or
substantial property damage.
WARNING!!!
Where exhaust
fans, clothes dryers, and kitchen
ventilation systems interfere
with the operation of appliances,
makeup air shall be provided.
Failure to follow this warning could
result in excessive levels of carbon
monoxide, which can cause severe
personal injury or death!
NOTICE! For installation in Canada, vent
pipe system must be certified to ULC-S636
(see Figure 11-7).
NOTICE! All vent pipes connections
must be secured following manufacturer
instruction, properly supported, and the
exhaust must be pitched a minimum of a
1/4 inch per foot back to the appliance (to
allow drainage of condensate).
69
NOTICE! The venting pipe shall be
installed with a means for condensate
disposal in order to prevent its
accumulation.
11.9.1 - Determine location
Locate the vent termination using the
following guidelines:
1.- The total length of piping for vent
must not exceed the limits given in the
Section 11.3;
2.- You must consider the surroundings
when terminating the vent:
a. Position the vent termination where
vapors will not damage nearby
shrubs, plants or air conditioning
equipment or be objectionable;
b. The flue products will form a
noticeable plume as they condense
in cold air. Avoid areas where
the plume could obstruct window
views;
c. Prevailing winds could cause
freezing of condensate and water/
ice buildup where flue products
impinge on building surfaces or
plants;
d. Avoid possibility of accidental
contact of flue products with people
or animals;
e. Do not locate the terminations
where wind eddies could affect
performance or cause recirculation,
such as inside building corners,
near adjacent buildings or surfaces,
window wells, stairwells, alcoves,
courtyards, or other recessed
areas;
f. Do not terminate above any door or
window. Condensate can freeze,
causing ice formations;
g. Locate or guard vent to prevent
condensate damage to exterior
finishes.
3.- The vent piping must terminate in an
elbow pointed outward as shown in
Figures 11-15 or 11-16 or in a roof as
shown in Figure 11-22;
