I. Pre-InstallationWARNINGIf you do not follow these instructions exactly,a fire or explosion may result causingproperty damage or personal injury.DANGERDo not install water heater where gasolineor other flammable vapors or liquids, orsources of hydrocarbons (i.e. bleaches,cleaners, chemicals, sprays, paint removers,fabric softeners, etc.) are used orstored.NOTICEDue to the low water content of the waterheater, mis-sizing of the water heater withregard to the heating system load will resultin excessive water heater cycling and acceleratedcomponent failure. Thermal SolutionsDOES NOT warrant failures causedby mis-sized water heater applications.DO NOT oversize the water heater to thesystem. Modular water heater installationsgreatly reduce the likelihood of water heateroversizing.A. Installation must conform to the requirements of theauthority having jurisdiction. In the absence of suchrequirements, installation must conform to the NationalFuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/CGA B149 Installation Codes. Where required theinstallation must conform to the standard for controlsand safety devices for automatically fired water heaters,ANSI/ASME CSD-1.B. Appliance is design certified for installation on combustibleflooring. Do not install water heater on carpeting.C. Provide clearance between water heater jacket andcombustible material in accordance with local fireordinance. Refer to Figure 1 for minimum listed clearancefrom combustible material. Recommended serviceclearance is 24 inches from left side, right side andfront. Recommended service clearance is 36” at rear ofunit. Service clearances may be reduced to minimumclearances to combustible materials.D. Install on level floor. Floor must be able to supportweight of water heater, water and all additional systemcomponents.6E. Protect gas ignition system components from water(dripping, spraying, rain, etc.) during water heater operationand service (circulator replacement, condensatetrap, control replacement, etc.).F. Provide combustion and ventilation air in accordancewith sections 5.3 of the National Fuel Gas code, ANSIZ223.1/NFPA 54, or sections 7.2, 7.3, or 7.4 of CAN/CSA B149.1, Natural Gas and Propane Installationcode, or applicable provisions of the local buildingcodes.WARNINGAdequate combustion and ventilation airmust be provided to assure proper combustion.The following guideline is based on the National Fuel GasCode, NFPA 54/ANSI Z223.1.1. Determine volume of space (water heater room).Rooms communicating directly with space (throughopenings not furnished with doors) are consideredpart of space.Volume [ft³] = Length [ft] x Width [ft] x Height [ft]2. Determine Total Input of all appliances in space.Round result to nearest 1,000 Btu per hour (Btuh).3. Determine type of space. Divide Volume by TotalInput.a. If result is greater than or equal to 50 ft³ per1,000 Btuh, space is considered an unconfinedspace.b. If result is less than 50 ft³ per 1,000 Btuh, spaceis considered a confined space.4. Determine building type. A building of unusuallytight construction has the following characteristics:a. Walls and ceiling exposed to outside atmospherehave a continuous water vapor retarder with arating of 1 perm or less with openings gasketedand sealed, and;b. Weather-stripping has been added on openablewindows and doors, and;c. Caulking or sealants applied in joints aroundwindow and door frames, between sill plates andfloors, between wall-ceiling joints, between wallpanels, at plumbing and electrical penetrations,and at other openings.
