Design and Application Details
OVENPAK®-II Burners are nozzle-mixing gasburners for many industrial direct-fired applicationswhere clean combustion and high turndown arerequired. They are simple and versatile for use on avariety of heating applications.
The Model “400” OVENPAK®-II Burner (shown atright) includes a face-mounted motor, blower withnon-sparking paddle wheel-type impeller, pilot, sparkignitor, stainless steel discharge sleeve, mixing cone,self-contained internal air and gas proportioningvalves, and provision for your flame safeguardsensor.
The blower housing can be rotated and mounted inthree alternate locations in 90° increments around theburner air inlet center line. Control motor and low firestart switches may be mounted on either the right orleft hand side of burner body.
Principle of operation (illustrated below)The OVENPAK®-II Burner is designed for industrial
air heating applications. It is available in two basicversions: 1) packaged with integral combustion airblower, or 2) for use with an external blower. Bothversions include a gas and air valve, internally linkedtogether to control the gas-air ratio over the fulloperating range. The gas flows through the nozzle,then along the inside of the burner cone wherecombustion air is progressively and tangentially mixedwith the gas. This produces a very wide turndownrange and a highly stable flame under a variety ofoperating conditions.
Model 415 OVENPAK®-II Gas Burner with optionalcombustion air filter, high and low fire position switch set,spark ignitor, provision for customer’s UV scanner and withconnecting base and linkage for electrical control motor

Design and Application Details
Model “EB” (external blower) OVENPAK®-IIBurners (shown in photos), like all OVENPAK® Burnerassemblies, are designed to deliver heat through apatented mixing cone and stainless steel sleeve.
Flanged burner body design on all OVENPAK®
Burner assemblies simplifies mounting and installa-tion on your application. Burner can be installed inany position that does not conflict with your controlmotor or flame detector requirements.
Minimal torque requirements permit use of mostelectric or air operators in conjunction with theoptional (Maxon supplied) connecting base andlinkage assemblies.
View into metallic cone of Model EB-3 OVENPAK®-IIBurner, arranged for external blower source, withconnecting base and linkage assembly to adapt customer'sautomatic control motor, and optional low fire start switcharrangement. Inlet air piping uses flexible connector set.
Model EB-3 OVENPAK®-II Burner with large viewing port,spark ignitor, standard pilot gas adjustable orifice, optionallow fire start switch arrangement, and connecting base andlinkage for mounting customer’s control motor
Standard Model “400” OVENPAK®-II Burnerincludes a combustion air blower with face-mountedmotor.
Maximum capacity of Model “400” OVENPAK®-IIBurner is affected by the static pressure within thecombustion chamber. Data shown assumes firing inthe open, or into an airstream with enough oxygen tocomplete the combustion process. If burner is firedinto an oxygen-starved chamber or airstream, capaci-ties may be reduced as much as 25-30%. Do notattempt to operate beyond the duct static pressurerange shown. For higher back pressure applications,select from Model “EB” OVENPAK®-II Burner options.
All gas pressures are differential pressures andare measured at the gas pressure test connection onthe backplate of each OVENPAK®-II Burner. Differen-tial pressures shown are approximate.

Accessory Options
Air filter assemblies and silencers
Air filter assemblies help to trap airborne particu-late matter. They are offered with washable replace-able filter elements or with permanent metallic ele-ments. Filters mount onto OVENPAK®-II Burner'sblower housing and surround the combustion air inlet.
Filter silencers help reduce noise levels. Theyphysically become a part of the OVENPAK®-IIBurner's filter housing and enclose the combustion airinlet (as shown in photograph at right). They must befurnished in conjunction with a filter element assemblydescribed above.
Sound levels from actualtests conducted at full-rated60 Hz capacity are shown intable at right. Measurementsare the average maximum athigh fire for standard burner(natural gas, 8" dischargesleeve).
When accessories and/or options are added, usethe following guidelines to calculate sound levels.
Filter (permanent) add 2 dB (3dB)
Silencer (with permanent filter) subtract 2 db (1 dB)
12" discharge sleeve add 2 dB
50 Hz motor – 83% capacity subtract 2 dB
Propane gas add 4 dB
Combine the adds and subtracts for net changewhen calculating sound levels with more than one ofthese options/accessories. (Example: A burner withsilencer and operating on propane would be 2 dBlouder.)
Silencer includes filter element as standard.NOTE: Background may affect on-site
measurements.

Auxiliary SwitchesLow Fire (or Set Position) Switch Assembly
includes one cam-actuated switch (2 SPST circuits)which can be set to open a circuit when burner leavesminimum (or set) position. It meets NEMA #4/IP665standards for weatherproof, outdoors, non-hazardouslocations.
High and Low Fire Position Switch Assemblyincludes 2 cam-actuated switches (each with 2 SPSTcircuits). One switch may be field-set to activate athigh fire position, while the other is set to activate atlow fire position.
Discharge Sleeves are available in 3 versions:
– Standard sleeve is 8" long, made of #310 SS, andis suitable for downstream temperatures up to1000°F (538°C).
– For higher velocities, specify 12" long sleevemade of #310 SS for downstream temperatures upto 1000°F (538°C).
– For higher downstream temperatures between1000°F (538°C) and 1500°F (816°C), specify 8"long, #RA 330 SS sleeve.
Oven Wall Adapter Plate provides a meansof mounting an OVENPAK®-II Burner in place of anolder style Model “400” OVENPAK® Burner.

Suggested Maintenance/Inspection Procedures
Discharge sleeve and cone alignmentThe mixing cone is self-centering within the burner
housing and discharge sleeve to provide a smallannular opening for the flow of some coolingcombustion air along the discharge sleeve wall. WeSUGGEST periodic inspection from the dischargeside of the burner to assure that this clearance ismaintained.
Blockage of the annular opening will lessenburner service life.
Filters should be inspected regularly andcleaned, using a vacuum to remove loose/dryaccumulations, then washing and/or degreasing asappropriate for the filter type used.
