Anleitung Zusammenfassung
• Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. -WHAT TO DO IF YOU SMELL GAS – • Do not try to light any appliance. • Do not touch any electrical appliance. • Do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. • Follow the gas supplier’s instructions. • If you cannot reach your gas supplier, call the fire department. • A qualified installer, service agency or the gas supplier must perform installation and service. • All installations must be made in accordance with all state and local codes, which may differ from instructions in this manual. • The installer should inform and demonstrate to the user the correct operation and maintenance of the appliance. • The installer shall also inform the user of hazards of flammable liquids and vapors and shall remove such liquids and vapors from the vicinity of the burner. • The installation adjustment data trap, or label supplied, shall be filled in and affixed to the burner or the covered appliance. These instructions should be affixed to the burner or adjacent to the heating appliance NYC MEA # 382-03-E Massachusetts Plumbing Board G1-0903-40:09/03/2004 Manufactured by Heat Wise, Inc. 1528 Rocky Point Road, Middle Island, NY 11953 rev 2004-2 Chart 1: Natural Gas and LP Burner Length Firing Rate Primary Secondary Total Total Gas Model of Flame Tube Electric Input Electric Input Watts Amps Conn.

BURNER DESCRIPTION The SU-2A Gas Burner is a fully automatic, flame retention burner and is suitable for combustion of natural gas or LP. Changing orifices alters the firing rate. The combustion air can be adjusted for proper O2 or CO2 by the dial located on top of the burner housing, which allows the air to flow more or flow less within the burner. Two electrodes act as a sparker and a flame rod (See Fig. 1). Flame rectification by this flame rod monitors the continued presence of the burner flame. With three trials for ignition consistency (with Fenwal control), trouble free, safe operation is achieved. Warning: Should overheating occur, 1) shut off the manual gas shut off valve to control the appliance; 2) DO NOT shut off the control switch to the pump or blower This power gas burner is designed to convert oil and/or coal fired boilers and furnaces to a gas-burning appliance. The conversion must conform to local codes. In the absence of such codes, the American National Standard for the Installations of gas conversion burners, ANSI Z21.17-1984, Z21.8A-1990 and the National Fuel Gas Code ANSI 223.1-1992 or current standards should be applied. Fig. 1 Electrode and Flame Sensor Dimensions CONVERTING OIL TO GAS Before attempting the gas conversion, check to insure the heating system is properly sized for the total heating demand and the entire system is in good operating condition, including the fire chamber and flue passages. It is important to allow adequate clearance around the appliance for servicing and proper operation of the burner. CONVERTING COAL TO GAS When converting a coal appliance to gas, the coal firing chamber or the ash pit chamber may be used as a gas firing chamber, provided the flame does not impinge on the walls of the appliance (see Chart 2). It is important to allow adequate clearance around the appliance for servicing and proper operation of the burner.

The intakes must terminate facing down in order to avoid obstruction from rain, snow, leaves, etc. Openings must have one square inch of free area per 10,000 BTU input rate (see Example 1). Follow the heat exchanger manufacturer's recommendations for installing louvers, etc. Example 1: 150,000 BTU/hr firing rate 1in 2 (150 000 BTU / hr ) * = 15 , () in 2 10 000 BTU / , hr CHIMNEY REQUIREMENTS The chimney should extend at least 3’ above a flat roof or the highest roof ridge (see Fig. 2) and be free in a radius of 30’ of objects such as tree limbs, other buildings, etc, which may cause a down draft. The chimney should be lined as required by the local Gas Company or local codes. Some utilities require new chimney liners for ...
