General Venting Information - American Standard UY060R9V3W Series Installer's Manual

THIS FURNACE MUST BE VENTED TO THE OUTDOORS.
THESE FURNACES ARE INDUCED DRAFT VENTED
AND MUST NOT BE CONNECTED TO ANY VENT
SERVING ANOTHER APPLIANCE. PLEASE NOTE THAT
THESE FURNACES USE POSITIVE-PRESSURE VENT
SYSTEMS.
Proper venting is essential to obtain maximum efficiency
from a condensing furnace. Proper installation of the vent
system is necessary to assure drainage of the condensate and
prevent deterioration of the vent system.
American Gas Association has certified the design of con-
densing furnaces for a minimum of 0" clearance from com-
bustible materials with a single wall plastic vent pipe.
The recommended system is assembled from 2", 2-1/2", or
3" plastic pipe and fittings (See Table 7, page 15). Where
the system is routed to the outdoors through an existing
masonry chimney containing flue products from another
gas appliance, or where required by local codes, then
3" venting of Type 29-4C stainless steel must be used in
place of PVC material.
These furnaces have been classified as CATEGORY IV
furnaces in accordance with ANSI Z21.47 "latest edition"
standards. Category IV furnaces operate with positive vent
pressure and with a vent gas temperature less than 140° F.
above the dewpoint. These conditions require special venting
systems, which must be gas tight and water tight.
NOTE:
When an existing furnace is removed from a venting
system serving other gas appliances, the venting system is
likely to be too large to properly vent the remaining
attached appliances.
The following steps shall be followed with each appliance
remaining connected to the common venting system placed
in operation, while the other appliances remaining connected
to the common venting system are not in operation.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion or other deficiencies which
could cause an unsafe condition.
3. Insofar as is practical, close all building doors and
windows and all doors between the space in which the
appliances remaining connected to the common venting
system are located and other spaces of the building. Turn
on clothes dryers and any appliances not connected to
the common venting system. Turn on any exhaust fans,
such as range hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate a summer
exhaust fan, close fireplace dampers.
4. Follow the lighting instructions. Place the appliance
being inspected in operation. Adjust thermostat so
appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after
5 minutes of main burner operation. Use the flame of a
match or candle, or smoke from a cigarette, cigar, or pipe.
6. After it has been determined that each appliance remain-
ing connected to the common venting system properly
vents when tested as outlined above, return door, win-
dows, exhaust fans, fireplace dampers and any other
gas-burning appliance to their previous conditions of use.

GENERAL VENTING INFORMATION

If improper venting is observed during any of the above tests,
the remaining common venting system must be corrected.
Correction could require rerouting or resizing the remaining
vent system.
HORIZONTAL INSTALLATION
(UPFLOW / HORIZONTAL OR DOWNFLOW / HORIZONTAL)
NOTE:
When the factory supplied 2X3" offset reducing coupling is
used for 3" vent pipe installation, make sure the marking
"TOP" is located on the top side of the pipe. The straight
side of the coupling must be on bottom for proper drainage
of condensate.
The following warning complies with State of California law, Proposition 65.
Hazardous Gases!
Exposure to fuel substances or by-products of incomplete
fuel combustion is believed by the state of California to
cause cancer, birth defects, or other reproductive harm.
Carbon monoxide, fire or smoke can cause serious bodily
injury, death, and/or property damage.
A variety of potential sources of carbon monoxide can be
found in a building or dwelling such as gas-fired clothes
dryers, gas cooking stoves, water heaters, furnaces and
fireplaces. The U.S. Consumer Product Safety Commission
recommends that users of gas-burning appliances install
carbon monoxide detectors as well as fire and smoke detec-
tors per the manufacturer's installation instructions to help
alert dwelling occupants of the presence of fire, smoke or
unsafe levels of carbon monoxide. These devices should be
listed by Underwriters Laboratories, Inc. Standards for
Single and Multiple Station Carbon Monoxide Alarms,
UL 2034 or CSA International Standard, Residential
Carbon Monoxide Alarming Devices, CSA 6.19
NOTE:
The manufacturer of your furnace does not test any
detectors and makes no representations regarding any
brand or type of detector.
