LCD INSTALLATION AND OPERATION INSTRUCTIONS Page 3RATINGS & CAPACITIESBefore undertaking the installation of the LCD Seriesboiler/water heater check the rating plate to ensurethat the unit has been sized properly for the job. The“Net I=B=R Ratings” specify the equivalent amountof direct cast iron radiation that the unit can supplyunder normal conditions. Also ensure that the unit hasbeen set up for the type of gas available at theinstallation site. Other important considerations arethe availability of an adequate electrical supply, fresh airfor combustion and a suitable chimney or vent system.BOILER/WATER HEATER LOCATION1. This boiler/water heater is suitable for indoor andoutdoor installations. Locate the boiler/water heaterin an area that provides good access to the unit.Servicing may require the removal of jacket panels.Allow the minimum clearances between adjacentconstruction and the boiler/water heater as listed inTable 1.NOTE: Service clearances are not mandatory, butare recommended to ensure ease of service shouldit be required.Table 1Clearance to ServiceCombustibles Clearancein mm in mmTop 6 153 20 508Back 6 153 24 610Left Side 6 153 24 610Right Side 6 153 24 610Front 6 153 30 762Flue 6 1532. An optimum site will be level, central to the pipingsystem, close to a chimney or outside wall and haveadequate fresh air for combustion. Ensure that theboiler/water heater is level from front to back andfrom side to side. Use metal shims to level theboiler/water heater. Electrical and electroniccomponents must also be protected from exposureto water during operation and maintenance. DONOT install this boiler/water heater in a location thatwould subject any of the gas ignition componentsto direct contact with water or excessive moistureduring operation or servicing.3. Ensure that the fl oor is structurally sound and willsupport the weight of the boiler/water heater.NOTE: The LCD may be installed directly oncombustible flooring, but never on carpeting.4. Locate the boiler/water heater in an area that willprevent water damage to adjacent construction shoulda leak occur or during routine maintenance. If such alocation doesn’t exist, a suitable drain pan that’sadequately drained must be installed under the unit.5. DO NOT place this boiler/water heater in a locationthat would restrict the introduction of combustion airinto the unit or subject the air inlet to a negativepressure, see “GENERAL VENTING GUIDELINES”.WARNING: Never store combustible materials,gasoline or any product containing flammablevapors or liquids in the vicinity of the boiler/water heater. Failure to comply with this warningcan result in an explosion or fire causingextensive property damage, severe personalinjury or death!6. NEVER place this boiler/water heater in a locationthat would subject it to temperatures at or nearfreezing. See the “Freeze Protection Section” onpage 14.CAUTION: Units installed outdoors MUST beprotected from ice and snow accumulation or theunit will be damaged voiding the warranty!COMBUSTION AIR & VENTILATIONWARNING: This boiler/water heater must besupplied with combustion air in accordance withSection 5.3, Air for Combustion & Ventilation, ofthe latest revision of the National Fuel Gas Code,ANSI Z223.1/NFPA 54 and all applicable localbuilding codes. Canadian installations mustcomply with CSA B149.1 or .2 Installation Codefor Gas Burning Appliances and Equipment, orapplicable provisions of the local building codes.Failure to provide adequate combustion air forthis boiler/water heater can result in excessivelevels of carbon monoxide which can result insevere personal injury or death!To operate properly and safely this boiler/waterheater requires a continuous supply of air forcombustion. NEVER store objects on or aroundthe boiler/water heater!CAUTION: Combustion air contaminated withfluorocarbons or other halogenated compoundssuch as cleaning solvents and refrigerants willresult in the formation of acids in the combustionchamber. These acids will cause premature failureof the boiler/water heater voiding the warranty!CAUTION: If the boiler/water heater is operated whilethe building is under construction it MUST beprotected from wood, concrete, sheet rock and othertypes of dust. Failure to properly protect the unitfrom construction dust will damage the unit voidingthe warranty!
