warning - Nordyne

NOTE: Industry research studies indicate thatwhen condensate is routed to an active drain,household detergents, etc., buffer its acidity. Ifthe drain is not actively used or if codes require,obtain a neutralizer kit (usually contains limestone).Proper drains and connections to thecondensate tubing are required as NORDYNEcannot be held responsible for water leakagewhich occurs due to loose hose connections orimproperly sealed drain line pipes.GAS SUPPLY AND PIPINGThis furnace is equipped for either left or rightside gas entry. Typical gas service hook-upsare shown in Figure 25. When making the gasconnection provide clearance between the gassupply line and the entry hole in the furnacecasing to avoid unwanted noise and/or damageto the furnace.All gas piping must be installed in compliancewith local codes and utility regulations. Somelocal regulations require the installation of amanual main shut-off valve and ground jointunion external to the furnace. The shut-off valveshould be readily accessible for service and/oremergency use. Consult the local utility or gassupplier for additional requirements regardingplacement of the manual main gas shut-off. Inthe absence of local codes the gas line installationmust comply with the latest edition ofthe National Fuel Gas Code (ANSI Z223.1) or(CAN/CGA B149) installation codes.An 1/8” NPT plugged tap must be installed in thegas line to the unit for use when measuring thegas supply pressure. The plug should be readilyaccessible for service use. A drip leg should beinstalled in the vertical pipe run to the unit. Table 5lists gas flow capacities for standard pipe sizes asa function of length in typical applications basedon nominal pressure drop in the line.NOTE: Gas piping must not be run in or throughair ducts, chimneys, gas vents, elevator shafts,etc.Compounds used on threaded joints of gas pipingmust be resistant to the actions of liquefi edpetroleum gases.The main manual gas valve and main power disconnectto the furnace must be properly labeledby the installer in case emergency shutdown isrequired.CAUTION:Do not use matches, lighters, candles,or other sources of open flame to checkfor gas leaks.Leak CheckWARNING:FIRE OR EXPLOSION HAZARDFailure to follow the safety warningsexactly could result in serious injury,death or property damage.Never test for gas leaks with an openflame. Use a commercially availablesoap solution made specifically for thedetection of leaks to check all connections.A fire or explosion may resultcausing property damage, personalinjury or loss of life.After the gas piping to the furnace is complete,all connections must be tested for gas leaks.To check for leaks use only a soap and watersolution or other approved method.IMPORTANT NOTE: When pressure testinggas supply lines at pressures greater than1/2 psig (14 in. water column), the furnacemust be disconnected from the gas supplypiping system to prevent damage to the gascontrol valve. If the test pressure is less thanor equal to 1/2 psig (14 in. water column), thefurnace must be isolated from the gas supplyline by closing the manual shut-off valve.WARNING:This furnace was equipped at thefactory for use with natural gas only.A special kit, supplied by the manufacturer,is required to convert thefurnace to operate on LP/propane gas.Failure to use the proper conversionkit can cause fire, explosion, propertydamage, carbon monoxide poisoning,personal injury, or death.28
