Sidewall Termination - Two Pipes; Vent/Air Termination; Determine Location - RBI Infinite Energy2 IW199 Installation And Operation Instructions Manual

11 - INSTALLATION - CATEGORY IV: Vent and combustion air
WARNING!!!
the maximum lengths of the
outside vent piping shown in
Figures 11-15, 11-16 or 11-22.
Excessive length exposed to the
outside could cause freezing
of condensate in the vent pipe,
resulting in potential appliance
shutdown.
4.- Maintain clearances as expected
by "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.
Also maintain the following:
a. Vent must terminate:
• At least 6 feet from adjacent walls;
• No closer than 12 inches below
roof overhang;
• At least 7 feet above any public
walkway;
• At least 3 feet above any forced
air intake within 10 feet;
• No closer than 4 feet below or
horizontally from any door or
window or any other gravity air
inlet.
Item unique to U.S.: vent for this
appliance shall not terminate:
i) over public walkways; or
ii) near soffit vents or crawl
space vents or other areas
where condensate or vapor
could create a nuisance or
hazard or cause property
damage; or
iii) where condensate vaper
could cause damage or
could be detrimental to the
operation of regulators, relief
valves, or other equipment.
b. Do not terminate closer than 4
feet horizontally from any electric
meter, gas meter, regulator, relief
valve, or other equipment. Never
terminate above or below any of
these within 4 feet horizontally.Item
unique to CANADA: vent system
shall terminate at least 6 ft from
electrical and gas meters.
5.- Locate 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.

Do not exceed
pipes
11.10.1 - Vent/air
termination
WARNING!!!
extending through an exterior
wall shall not terminate
adjacent to a wall or below
building extensions such as
eaves, parapets, balconies, or
decks. Failure to comply could
result in severe personal injury,
death, or substantial property
damage.
WARNING!!!
connect any other appliance
to the vent pipe or multiple
appliances to a common vent
pipe. Failure to comply could
result in severe personal injury,
death, or substantial property
damage.
NOTICE! Installation must comply
with local requirements and with the
National Fuel Gas Code, ANSI Z223.1
for U.S. installations or CSA B149.1
for Canadian installations.
11.10.2 - Determine
location
Locate the vent/air terminations using
the following guidelines:
1.- The total length of piping for vent
2.- You must consider the
A gas vent

or air must not exceed the limits
given in the Section 11.3;
surroundings when terminating the
vent and air:
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.
