18CARBON MONOXIDE POISONING HAZARDFailure to follow the steps outlined below for eachappliance connected to the venting system being placed intooperation could result in carbon monoxide poisoning ordeath.The following steps shall be followed for each applianceconnected to the venting system being placed intooperation, while all other appliances connected to theventing system are not in operation:1. Seal any unused openings in venting system.2. Inspect the venting system for proper size and horizontalpitch, as required in the National Fuel Gas Code, ANSIZ223.1--2002/NFPA 54--2002 or the CSA B149.1, NaturalGas and Propane Installation Code and these instructions.Determine that there is no blockage or restriction, leakage,corrosion and other deficiencies, which could cause anunsafe condition.3. As far as practical, close all building doors and windowsand all doors between the space in which the appliance(s)connected to the venting system are located and otherspaces of the building.4. Close fireplace dampers.5. Turn on clothes dryers and any appliance not connectedto the venting system. Turn on any exhaust fans, such asrange hoods and bathroom exhausts, so they are operatingat maximum speed. Do not operate a summer exhaust fan.6. Follow the lighting instructions. Place the appliancebeing inspected into operation. Adjust the thermostat soappliance is operating continuously.7. Test for spillage from draft hood equipped appliances atthe draft hood relief opening after 5 minutes of main burneroperation. Use the flame of a match or candle.8. If improper venting is observed during any of the abovetests, the venting system must be corrected in accordancewith the National Fuel Gas Code, ANSIZ223.1--2002/NFPA 54--2002 and/or CSA B149.1, NaturalGas and Propane Installation Code.9. After it has been determined that each applianceconnected to the venting system properly vents when testedas outlined above, return doors, windows, exhaust fans,fireplace dampers and any other gas--fired burningappliance to their previous conditions of use.CAUTION!Step 9 —Combustion Air and Vent Pipe SystemsGENERALVent system or vent connectors of other appliances may need tobe resized. For any other appliances when resizing vent systemsor vent connectors, system or connector must be sized toapproach minimum size as determined using appropriate tablefound in the NFGC or NSCNGPIC.The 58UVB can be vented as either a direct vent furnace or as anoptional ventilated combustion air application. A direct ventsystem shall be installed in accordance with the direct vent(2--pipe) procedures in the following Combustion Air and VentPipe Systems section. For optional ventilated combustion airapplications, refer to the ventilated combustion air optionprocedures in the same section. Common venting prohibited.DIRECT VENT/2--PIPE SYSTEMIn a direct--vent (2--pipe) system, all air for combustion is takendirectly from outdoor atmosphere, and all flue products aredischarged to outdoor atmosphere. Combustion--air and ventpipes must terminate together in the same atmospheric pressurezone, either through the roof or a sidewall (roof terminationpreferred). A factory accessory vent termination kit MUST beused in a direct vent (2--pipe) system. See Table 6. See Fig. 34for required clearances.VENTILATED COMBUSTION AIR OPTIONIn a ventilated combustion air option, the vent terminates anddischarges the flue products directly to the outdoors similar to adirect vent system. See Fig. 35 for required clearances. All airfor combustion is piped directly to the furnace from a space thatis well ventilated with outdoor air (such as an attic or crawl space)and the space is well isolated from the living space or garage.MATERIALSCombustion--air and vent pipe, fittings, primers, and solventsmust conform to American National Standards Institute (ANSI)standards and American Society for Testing and Materials(ASTM) standards. See Table 5 for approved materials for use inthe U.S.A.FIRE AND EXPLOSION HAZARDFailure to follow this warning could result in fire,property damage, personal injury, or death.Solvent cements are combustible. Keep away from heat,sparks, and open flame. Use only in well ventilatedareas. Avoid breathing in vapor or allowing contactwith skin or eyes.! WARNINGIn Canada, construct all combustion--air and vent pipes for thisunit of CSA or ULC listed schedule--40 PVC, PVC--DWV orABS--DWV pipe and pipe cement. SDR pipe is NOT approved inCanada.CARBON MONOXIDE POISONING HAZARDFailure to follow this warning could result in propertydamage, personal injury, or death.All combustion--air and vent pipes must be airtight andwatertight. Pipes must also terminate exactly as shownin Fig. 31 for direct vent (2--pipe) system or Fig. 32 forventilated combusion air option.! WARNINGAn abandoned masonry chimney may be used as a raceway forproperly insulated and supported combustion--air (whenapplicable) and vent pipes. Each furnace must have its own set ofcombustion--air and vent pipes and be terminated individually, asshown in Fig. 31 for Direct Vent (2--Pipe) system or Fig. 32 forventilated combusion air option.A furnace shall not be connected to a chimney flue serving aseparate appliance designed to burn solid fuel.Other gas appliances with their own venting system may also usethe abandoned chimney as a raceway providing it is permitted bylocal code, the current edition of the National Fuel Gas Code andthe vent or liner manufacturer’s installation instructions. Caremust be taken to prevent the exhaust gases from one appliancefrom contaminating the combustion air of other gas appliances.Do not take combustion air from inside the chimney when usingthe Ventilated Combustion Air option.58UVB
