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 play 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
