Determining Product Location Before locating the ELITE check for convenient locations to: - Domestic water supply piping - Heating system piping -Venting - Gas or oil supply piping - Electrical service Ensure the area chosen for the installation of the ELITE is free of any combustible materials, gasoline and other flammable liquids. WARNING Failure to remove or maintain the area free of combustible materials, gasoline and other flammable liquids or vapors can result in severe personal injury, death or substantial property damage. 5 Ensure the ELITE and its controls are protected from dripping or spraying water during normal operation or service. The ELITE should be installed in a location so that any water leaking from the tank or piping connections or relief valves will not cause damage to the area surrounding the unit or any lower floors in the structure. -When such a location is unavoidable a suitable drain pan with adequate drainage should be placed under the unit. The drain pan must not restrict the flow of combustion air to the unit. Boiler Replacement If the ELITE is replacing an existing boiler / hot water heater system, the following items should be checked and corrected prior to installation: • Primary and domestic piping leaks and corrosion. • Improper location and sizing of the expansion tank on the primary heating loop. • Improper sizing of the thermal expansion tank (if used) on the domestic supply line. •Vent condition and sizing. Recommended Clearances The ELITE is approved for zero clearance to combustibles, excluding the vent hood and vent piping. Vent hood and vent piping - 6 inches from combustible materials when using type “L” double wall vent. Vent Piping - 18 inches from combustible materials when using single wall vent. Primary and domestic hot water piping - 1 inch from combustible material. Pre-Installation Items BEST PRACTICES To provide serviceability to the unit it is recommended that the following clearances be maintained: Top and vent hood area - 36 inches. Front and burner area - 24 inches. Rear and primary piping areas - 12 inches. WARNING When installing the ELITE in a confined space, sufficient air must be provided for proper combustion and venting and to allow under normal operating condition, proper air flow around the product to maintain ambient temperatures within safe limits to comply with the National Fuel Gas Code NFPA 54 - latest edition. Flooring and Foundation The ELITE is approved for installation on combustible floors, but never on carpeting. WARNING Do not install the ELITE on carpeting even with a metal or wood foundation base. Fire can result causing severe personal injury, death or substantial property damage. Installer should provide a solid brick or concrete foundation pad, at least 2 inches above the floor level if: -There is a potential for the floor to become flooded. The height of the...
