Carbon Monoxide Poisoning; General Venting Requirements - Carrier 140/E Series Installation, Start--Up, Operating, And Service And Maintenance

CARBON MONOXIDE POISONING HAZARD
Failure
to follow the steps outlined below for each
appliance connected to the venting system being placed into
operation could result in carbon monoxide poisoning or
death. The following steps shall be followed for each
appliance connected to the venting system being placed into
operation, while all other appliances connected to the
venting system are not in operation:
1. Seal any unused openings in venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 and these
instructions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies,
which could cause an unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which
the appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they are operating at maximum speed.
Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. Test for spillage from draft hood equipped
appliances at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a
match or candle.
8. If improper venting is observed during any of the
above tests, the venting system must be corrected in
accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54.
9. After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other
gas-fired burning appliance to their previous
conditions of use.
Vent system or vent connectors may need to be resized. Vent
systems or vent connectors must be sized to approach minimum
size as determined using appropriate table found in the NFGC.
GENERAL VENTING REQUIREMENTS
Follow all safety codes for proper vent sizing and installation
requirements, including local building codes, the National Fuel
Gas Code ANSI Z223.1-2009/NFPA 54-2009 (NFGC), Parts 12
and 13 in the United States, the local building codes, and furnace
and vent manufacturers' instructions.
These furnaces are design-certified as Category I furnaces in
accordance with ANSI Z21.47-2006/CSA 2.3-2006 and operate
with a non-positive vent static pressure to minimize the potential
for vent gas leakage. Category I furnaces operate with a flue loss
not less than 17% to minimize the potential for condensation in
the venting system. These furnaces are approved for common
venting and multi-story venting with other fan assisted or draft
hood equipped appliances in accordance with the NFCG, local
building codes, and furnace and vent manufacturers' instructions.
The following information and warning must be considered in
addition to the requirements defined in the NFGC.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
iniury or death.
Do not bypass the draft safeguard switch, as an unsafe
condition could exist which must be corrected.
1. If a vent (common or dedicated) becomes blocked, the fur-
nace will be shut off by the draft safeguard switch located
on the vent elbow.
2. Two-stage furnaces require Type B vent connectors out-
side the casing in all configurations. Single wall vent con-
nector may be used inside the furnace casing with the
transition to Type B vent outside the furnace casing. Size
the connector so that the FAN-Min vent connector capa-
city is equal to or lower than the low fire rate of the fur-
nace and the FAN-Max vent connector capacity is equal
to or higher than the furnace high fire rate.
3. Do not vent this Category I furnace into a single wall ded-
icated or common vent. The dedicated or common vent is
considered to be the vertical portion of the vent system
that terminates outdoors.
4. Vent connectors serving Category I furnaces shall not be
connected into any portion of a mechanical draft system
operating under positive pressure.
5. Do not vent this appliance with any solid fuel burning ap-
pliance.
6. Category I furnaces must be vented vertically or nearly
vertically unless equipped with a listed mechanical venter.
See the SIDEWALL VENTING section.
7. Do not vent this appliance into an unlined masonry china-
ney. Refer to Chimney Inspection Chart, Fig. 34.
MASONRY CHIMNEY REQUIREMENTS
NOTE: These furnaces are CSA design-certified for use in
exterior tile-lined masonry chimneys with a factory accessory
Chimney Adapter Kit. Refer to the furnace rating plate for correct
kit usage. The Chimney Adapter Kits are for use with ONLY
furnaces having a Chimney Adapter Kit number marked on the
furnace rating plate.
If a clay tile-lined masonry chimney is being used and it is
exposed to the outdoors below the roof line, relining might be
required. Chimneys shall conform to the Standard for Chimneys,
Fireplaces, Vents, and Solid Fuel Burning Appliances
ANSI/NFPA 211-2009 in the United States and must be in good
condition.
U.S.A.-Refer to Sections 13.1.8 and 13.2.20 of the NFPA 54 /
ANSI Z223.1-2009 or the authority having jurisdiction to
determine whether relining is required. If relining is required, use
a properly sized listed metal liner, Type-B vent, or a listed
alternative venting design.
NOTE: See the NFPA 54 / ANSI Z223.1-2009, 13.1.8 and
13.2.20 regarding alternative venting design and the exception,
which cover installations such as the Chimney Adapter Kits
which are listed for use with these furnaces. See Table 18 for
accessory listing.
