Product Overview | Magna-Flame ™ Burner
FEATURES
IGNITION AND FLAME SUPERVISION
— Gas-only burner — Broad stability range
Magna-Flame burners should be pilot ignited . Pilot ignition must occur at 1"w.c. main air pressure or less. Appropriate 4014 gas-boosted pilots are to be used with this burner (sold separately), and are shown on the dimension table. Pilot operation must be interrupted to prevent overheating of the mounting. Self-checking UV scanners (sold separately) are recommended for flame supervision. See Bulletin 8832 for selection of UV adapters. It is possible for a UV scanner mounted on this burner to sight flame(s) of other burners in the same firing chamber. Consult North American for configuration guidance on multiple burner applications. INSTALLATION The burner does not include a tile. The tunnel shape shown on the dimension drawing (page 3) must be built into the combustion chamber wall. See Supplement DF-M1 for installation recommendations.
— Chambers up to 2200°F — Excellent for low Btu fuels
4795 Magna-Flame™ Gas Burners are used on a wide variety of industrial heating applications. Flame lengths vary from 9 to 35 feet. Operation is quiet, and the flame is stable over a wide range of air/gas ratios: from more than 50% rich to 1000% excess air. Burners can be used in cold, sealed-in chambers running on stoichiometric ratio or lean. CONSTRUCTION Body is fabricated of heavy duty welded steel featuring a round mounting flange, a refractory ring and alloy air distribution disc in the front. Connections for pilot and flame detector are available in a variety of locations which are specified during ordering. See Dimensions, page 3. CONTROL Use either mass flow control or cross-connected regulator systems. Gas pressure requirement at the burner is approximately 0.6 times the air pressure.
REPLACEMENT AND SPARE PARTS
NOTE: In June, 2009, the 4795 burner was redesigned to change from a square mounting flange to round and replace the threaded gas connection with a flanged gas tee. When replacing burners, or ordering parts, please inform your sales professional of the complete part number, sales order and/or manufactured date. This information is stamped on a tag located on the burner back plate .

Because of a positive pressure in the burner, it is difficult to light with a torch unless the air is turned very low and a strong pressure torch is used. Maximum recommended pressure.
