7W415-0810 / 06.11.096.1If the appliance is equipped with plated parts, you must clean fingerprints or other marks from the platedsurfaces before operating the appliance for the first time. Use a glass cleaner or vinegar and towel to clean.If not cleaned properly before operating for the first time, the marks can cause permanent blemishes on theplating. After the plating is cured, the fingerprints and oils will not affect the finish and little maintenance isrequired, just wipe clean as needed. Prolonged high temperature burning with the door ajar may cause apermanent rain bowing effect on the lower edge of a gold plated door (applies to wood product only).NOTE: The protective wrap on plated parts is best removed when the assembly is at roomtemperature but this can be improved if the assembly is warmed, using a hair dryer or similar heatsource.1.4 GENERAL INFORMATION4.2As long as the required clearance to combustibles ismaintained, the most desirable and beneficial location for aNapoleon® appliance is in the center of a building, therebyallowing the most efficient use of the heat created. Thelocation of windows, doors and the traffic flow in the roomwhere the appliance is to be located should be considered.If possible, you should choose a location where the vent willpass through the house without cutting a floor or roof joist.When the appliance is installed directly on carpeting, vinyl tile or other combustible material other than woodflooring, the appliance shall be installed on a metal or wood panel extending the full width and depth.We suggest that our gashearth products be installedand serviced by professionalswho are certified in the U.S.by the National ApplianceInstitute® (NFI) as NFI GasSpecialistswww.nficertified.orgFOR YOUR SATISFACTION, THIS APPLIANCE HAS BEEN TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY!MAXIMUM INPUT: Is 30,000 BTU/hr for natural gas and propane. When the appliance is installed at elevationsabove 2,000ft, and in the absence of specific recommendations from the local authority having jurisdiction, thecertified high altitude input rating shall be reduced at the rate of 4% for each additional 1,000 ft.MINIMUM INLET: Gas supply pressure is 4.5 inches water column for natural gas and 11 inches water columnfor propane.MAXIMUM INLET: Gas pressure is 7 inches water column for natural gas and 13 inches water column for pro-pane. Manifold pressure under flow conditions is 3.5 inches water column for natural gas and 10 inches watercolumn for propane.No external electricity (110 volts or 24 volts) is required for the gas system operation. Expansion / contrac-tion noises during heating up and cooling down cycles are normal and are to be expected. This appliance isequipped with a pilot light safety system referred to as an oxygen depletion sensor and is designed to turn offthe appliance if not enough fresh air is available.1.5 CARE OF PLATED PARTS2.0 INSTALLATIONThe GVF40 is rated at 30,000 BTUs per hour for natural gas and 28,500 BTUs for propane and therefore re-quires a minimum unconfined space of 1,500 and 1,425 cubic feet respectively.17.1This appliance shall not be installed in a confined space or unusually tight construction unless provisions areprovided for adequate combustion and ventilation air.The National Fuel Gas Code, ANSI Z223.1 defines a confined space as a space whose volume is less than 50cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in thatspace and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour(4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicatingdirectly with the space in which the appliances are installed, through openings not furnished with doors areconsidered a part of the unconfined space.2.1 COMBUSTION AND VENTILATION AIR PROVISIONS
