Instructions for the installer3.17 - INSTALLATION OF THE EXHAUSTAND AIR INTAKE SYSTEMNOTICEConsult local and state codes pertaining to specialbuildingcode and fire department requirements. Adhereto nationalcode requirements.12’’ (305 mm)minimumEXHAUST12’’ (305 mm)minimumNOTICEObserve the listed maximum lengths of vent systemwhich are boiler model dependent.The maximumpermissible lenghts are listed at page 26- 2912’’ (305 mm)minimumINTAKE12’’ (305 mm)minimum12’’ (305 mm)minimumMinimum clearance of 4 ft (1.22m) horizontally from, and in nocase above or below, unless a 4 ft (1.22 m) horizontal distanceis maintained, from electric meters, gas meters, regulatorsand relief equipment.The minimum distance from adjacent public walkways, adjacentbuildings, openable windows and building openings shallnot be less than those values specified in the National FuelGas Code, ANSI Z223.1 / NFPA 54 and / or the Natural Gasand Propane <strong>Installation</strong> Code, CAN/CSA B149.1Do not extend exposed vent pipe outside the building beyondrecommended distance. Condensate could freeze and blockvent pipe.Vent should terminate at least 3 ft (915 mm) away from adjacentwalls, inside corners and 5 ft (1525 mm) below roof overhang(see figure).it is not recommended to terminate vent above any door orwindow, condensate can freeze causing ice formations.Do not use chimney as a raceway if another boiler or fireplace is vented into or through chimney.NOTICETerminals should be positioned as to avoid productsof combustion entering openings into buildingsor other vents.NOTICETerminals should be positioned as to avoid productsof combustion entering openings into buildingsor other vents.NOTICEMaintain 12” of clearance above the highest anticipatedsnow level or grade or, whichever is greater.Please refer to your local codes for the snowlevel in your area.NOTICEThe whole route of the vent system must be installedupwards, never downwards,completely nor partly.NOTICEThe terminal should be located where dispersalof combustion products is not impeded and withdue regard for the damage or discolouration thatmight occur to building products in the vicinity(see above figure).In certain weather conditions condensation mayalso accumulate on the outside of the air inletpipe. Such conditions must be considered andwhere necessary insulation of the inlet pipe maybe required.In cold and/or humid weather water vapor maycondense on leaving the vent terminal. The effectof such ‘water condensation’ must be considered.The terminal must be located in a place not likelyto cause a nuisance.26
Instructions for the installerThe flue system must be installed inaccordance with the local and nationalStandards.Use only original LATTNER flue outlet systems, which areprovided from the follow manufacturer:TABLE FLUE OUTLET SYSTEM3.18 - ROOM AIR SYSTEMFOR INSTALLATION USING INDOORCOMBUSTION AIRBoiler designed to be connected to an open flue which willterminate vertically through the roof. The combustion air iswithdrawn directly from the room where the boiler is installed.ItemDecriptionVentingpipe3.28 ftManufacturerSTABILEMaterialStainlessSteelCode LATTNER00362448WARNING: for this type of connection the room must complywith the same installation regulations valid for openchimney boilers.The chimney must comply to the current regulations.Ventingpipe1.62 ftSTABILEStainlessSteel00362449Elbow 90°STABILEStainlessSteel00362450Elbow 45°STABILEStainlessSteel00362451HorizontalFlue terminalVerticalFlueTerminalGROPPALLISTABILEAlluminiumStainlessSteel0036149300362452When using indoor air, LATTNER strongly recommends theuse of an indoor air filter.This boiler requires adequate combustion air for ventilationand dilution of flue gases.Failure to provide adequate combustion air can result in unitfailure, fire, explosion, serious bodily injury or death.Use the following methods to ensure adequate combustionair is available for correct and safe operation of this boiler.Damages caused by installation errors and for nonobservanceof the instructions given by the manufacturerwill invalidate all the supplier’s contractual or extracontractual responsibilities.If the boiler has to be replaced ALWAYS replace the flueoutlet system.The boiler has been tested and approved with the terminalsdistributed by <strong>Lattner</strong> that comply the requirements of ANSIZ21.13 / CSA 4.9 for the following flue configurations.Important: Combustion air must be free of corrosive chemicals.Do not provide combustion air from corrosive environments.Appliance failure due to corrosive air is not covered bywarranty.Combustion air must be free of acid forming chemical such assulfur, fluorine and chlorine. These chemicals have been foundto cause rapid damage and decay and can become toxic whenused as combustion air in gas appliances. Such chemicalscan be found in, but not limited to bleach, ammonia, cat litter,aerosol sprays, cleaning solvents, varnish, paint and air fresheners.Do not store these products or similar products in thevicinity of this boiler.Flue outlet systems must be purchasedfrom the dealer of products LATTNER.27
