Product Overview | 4422 Fire•All™
HINGED BURNER BODY (4422HR OR 4422HL)
OPTIONAL CONSTRUCTIONS
Burner connections are provided for mounting pilot or direct spark igniter, and flame detector. Burners are shipped with pipe plugs in the openings. Burner flame may be seen through the rear observation port. (Observation port is not to be used for mounting of flame detector.) Burner air pressure can be measured at the tap location provided. For additional construction information refer to Dimensions & Parts List 4422-2. LIGHTING AND FLAME SUPERVISION A 4011-12 pilot set is recommended for individual burner igni- tion. When multiple burners share a single pilot pre-mix header, a 4021-12 pilot tip per burner with an appropriately sized air/ gas mixer is recommended. A manual torch can be used in some applications. The burner can be direct spark ignited with either the 4055 Direct Spark Igniter (4055-D for 4422-2 through -6-B and 4055-B for 4422-7 and -8 sizes) or the 4051-D Air Assisted Igniter. The 4051 Air Assisted Igniter is recommended because it ignites the burners over a wider operating range. If using direct spark ignition of main flame, use standard 6000 volt transformer. Half-wave ignition transformers can be used only with the 4055. A flame rod or ultraviolet (UV) detector can be installed in one of three holes in the body, using an adapter listed in Bulletin 8832. UV scanners allow igniting with up to 14 osi main air. If flame rods are used, 4422-2 through -6 Burners must be ignited at 1 osi or more main air. Do not apply flame rods to -7 and -8 size burners. When using flame supervision, an interrupted pilot is required--do not use constant or intermittent pilots. Startup and Adjustment: Refer to Bulletin GB-M1 for startup and adjustment of a nozzle-mix burner with ratio regulator air/fuel ratio contro l. EQUIPMENT OPTIONS The 4422 Fire•All™ is offered in many physical arrangements to accommodate installation and operating requirements. DOUBLE PILOT AND FLAME SUPERVISORY CONNECTION (4422D)
There is a hinge between the cast mounting plate and burner body. The hinge provides easy access to the burner tunnel for cleaning deposits that may result from the process (incineration is an example). During operation, a latch firmly holds the burner body against the mounting plate. The burner is available with the hinge on either the right or left side. Pilot and flame detector connections are located opposite the hinge.
To specify hinge location: When looking at the rear of the burner with the air pipe entering from above (12 o'clock position) "HL" specifies the hinge on the left side (shown in draw- ing) while "HR" specifies the hinge on the right side. For dimension informa- tion refer to Dimensions & Parts List 4422-6.
4422HL
BURNER ONLY (4422- -BO)
The burner can be ordered without the tile and mounting plate. This is useful where a mounting plate and tile already exist or for special construction furnaces. Refer to Dimensions & Parts List 4422- 2. FLANGELESS MOUNTING (4422- -FM)
Used in furnace construction where there is no steel shell, only refractory. Identical to standard burners except no mounting flange. For dimension information refer to Dimensions & Parts List 4422-4. Only available with the standard burner or double boss option.
This special burner body has two sets of connections for mount- ing pilot or spark igniter and flame detector.This permits a variety of piping arrangements or redundant pilots and flame detectors. It is available only in -2 through-6-B burner sizes and is other- wise identical to a standard burner. For dimension information refer to Dimensions & Parts List 4422-5.
