Midco J83-DS User Manual

The Incinomite Model J83-DS incinerator gas burner features direct main flame spark ignition and solid state electronic flame
verification. It is adaptable to either primary or secondary chamber installations.

In the United States, installation must conform with local

codes or, in the absence of local codes, with National
Fuel Gas Code, ANSI Z223.1-latest edition available
from American National Standard Institute. Further ref­erence should be made to the recommendation of your
fuel supplier.

NOTE: Any additions, changes, or conversions required in

order for the gas utilization equipment to satisfactorily
meet the application needs must be made by a MIDCO
distributor (or other qualified agency) using factory
specified and approved parts.

In Canada, installation must conform with local codes or,

in the absence of local codes, with Installation Codes

for Gas Burning Appliances and Equipment, CGA
Standard CAN/CGA 1-B149.1 or 2. Further reference

should be made to the recommendation of your fuel sup
plier.

CODE COMPLIANCE IS THE SOLE RESPONSIBILITY
OF THE INSTALLER.

INSTALLER: Inform and demonstrate to the user the
correct operation and maintenance of this gas utiliza­tion equipment. Inform the userof the hazards of stor­ing flammable liquids and vapors in the vicinity of this
gas utilization equipment and remove such hazards.
Affix this manual adjacent to the incinerator burner.

WARNING: If the information in

these instructions is not followed
exactly, a fire or explosion may result,
causing property damage, personal
injury or death.

Do not store or use gasoline or other
flammable vapors and liquids in the
vicinity of this or any other appliance.

Installation and service must be per­formed by a qualified installer, serv­ice agency or the gas supplier.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electrical
switch; do not use any phone in
your building.

• Immediately call your gas
supplier from a neighbor's
phone. Follow the gas suppliers'
instructions.

• If you cannot reach your gas
supplier, call the fire department.

USER: Retain this manual for future reference. If other than routine service or maintenance
as described in this manual is required, contact a qualified service agency. DO NOT
ATTEMPT REPAIRS. An inadvertent service error could result in a dangerous condition.

SAFETY INFORMATION TERMS: The following terms are used to identify hazards, safety precautions or special

notations and have standard meanings throughout this manual. When you see the safety alert symbol and one of the
safety information terms as shown below, be aware of the hazard potential.

DANGER: Identifies the most serious hazards which will result in severe personal injury or death.

Specifications

II Indoor Ventilation

No. 1 Waste: Primarily dry material such as paper, rags and wood. Burner normally required only
for light-off.
No. 2 Waste: Consisting of approximately equal portions, by weight of No. 1 and No. 3 waste; 70
lbs. per 100 MBH.

No. 3 Waste: Wet material such as garbage; 25lbs. per 100 MBH.
No. 4 Waste: Organic materials such as small carcasses and waste from hospital operating rooms

or pathological laboratories; 13 lbs. per 100 MBH.
NOTE: The burner input required for the secondary chamber must be determined from the heat
required to maintain the discharge temperature of the flue products as specified by the EPA for the
type of waste involved and the location of the incinerator.

_________________________________

Make sure that the incinerator room has sufficient ventilation to provide the necessary combustion
air for the burner fuel, the waste material and any other appliance that would draw its air from the
same enclosed area.

WARNING: Under no condition should the access to outside air be so restricted that the
maximum possible use of combustion air is inhibited. Pay particular attention to exhaust
fans that could draw air from the area and create a negative pressure in the room.

_________________________________

Install the INCINOMITE burner(s) in location(s) specified by the incinerator manufacturer. It should
be positioned approximately level with the top of the highest normal load and fire with or across the
draft flow.

 If the incinerator is designed only for No. 4 waste, the level can be lowered to bring the flame to

fire directly on the smaller loads characteristic of this type of operation. The opening through which
the burner fires should be of a diameter only large enough to accommodate the Blast Tube (4 ¼"
diameter x 3" minimum long.) Do not allow the Blast Tube to protrude into the incineration cham­ber. If necessary, build an extension outside of the incinerator wall to increase wall depth.

 To change the Mounting Flange to its alternate position, horizontal or 10° down firing, remove

the four (4) screws that attach it to the burner, rotate the flange 180° and reinstall the screws.

 Before mounting the burner, check that the Blast Tube and Blower Housing are clear of foreign

material and that the Main Gas Port and Nozzle Support is clean and undamaged.

 If the incinerator is located outdoors, the burner and all of its components, except the Main

Manual Shut-Off Valve, must be protected from weather. The Midco

®

Accessory Weatherhood will

provide such protection.

CAUTION: If the incinerator is of the down draft design, make sure that a direct draft
vent opening of approximately 10 square inches has been put through the top of the drop
section(s) to provide for the venting of any gas leakage. See Figure 1.

_________________________________

The size and type of material used for the vent connector and chimney must conform to the rec­ommendations of the incinerator manufacturer, as well as local and national codes. This is espe­cially true where high flue gas temperatures are encountered.

 When natural draft is used and the chimney height is over 25 feet, a barometric damper of the

same size as the vent connector should be installed. If the chimney is high enough to make it dif­ficult for the barometric to maintain a maximum incineration chamber over-fire draft, 0 to minus

0.5" W.C., a fixed damper should be installed in the vent connector between the barometric and
chimney to restrict the chimney draft to a point within the controlling capacity of the barometric.
After final setting, the damper should be permanently fastened into position per ANSI Z223.1-lat­est edition "National Fuel Gas Code", or latest edition available from American National
Standards Institute to prevent tampering.

_________________________________

The supply piping to the burner should branch off from the main line as close to the source as
possible (NATURAL gas meter or
PROPANE tank regulator). When
branching off from an existing gas
line, do not tap o ff the bottom of a
horizontal section. Use new black
pipe and malleable fittings free
from cutting and threading burrs or
defects.

 Use pipe joint compound resist-

ant to liquid petroleum gases
when using either NATURAL or
PROPANE gas. Piping must com­ply with the local and national
codes. If the burner piping must be
rearranged because of space limi­tations, be sure to carry out the
general configuration shown in
Figure 2.

 A suitable Main Gas Pressure Regulator should be installed as shown in Figures 1 or 2

Choose a regulator(s) to adjust the available gas pressure to the pressure shown in SPECI­FICATIONS, page 2.

CAUTION: The regulated gas pressures must not exceed 14"W.C. or Main
Automatic Gas Valve and Ignitor Regulator will be damaged. If excessive gas pressure
is prevalent, the regulator must be a tight shut-off type to prevent high pressures from
developing during stand-by.
