OIL BURNER TECHNOLOGY Omni’s patented burner technology improves the e fficiency of the oil burn process by continuous stabilization of the oil viscosity. Optimum atom ization (spray) is accomplished by precisely pre- heating the oil and air prior to introduction to the combustion chamber. The waste oil enters into the Oil Pre-Heater Block (figur[...]

• Air Pressure Adjuster: (figure1) Adjusts the air pressure going to the pre-heater block. Should be adjusted between 12 PSI and 13PSI as indicated on the Air Pressure Gauge on the burner for thorough burn of the waste oil. Note: In order to insure proper air adjustment, air gauge must read 0 when burner is cycled off or powered down. • Oil Pre[...]

COMBUSTION AIR SUPPLY WARNING Failure to provide an adequate supply of fresh air for combustion will result in hazardous operating conditions. Note If you use a fireplace or a kitchen or bathroom exhaust fan, you should install an outside air intake. These devices will rob the boiler and water heater of combustion air. 1. In unconfined spaces in bu[...]

(b) All Air From Outdoors: The confined space shall be provided with two permanent openings, one within 12 inches of the top and another within 12 inches of the bottom of the enclosure. The openings shall comm unicate directly, or by ducts, with the outdoors or crawl or attic spaces which communicate freely with the outdoors. Direct To Outdoors, Se[...]

NOTE All wall openings directly to outdoors must be screened to prevent entry by birds or small animals. With Horizontal Ducts See Figure 10. Note: Each air duct opening shall have a free area of not less than one square inch per 2,000 Btu per hour of the total input rating of all equipment in the enclosure.* Chimney Outlet Air Duct Inlet Air Duct [...]

3. Breeching • See Table 2 for minimum recommended breeching and chim ney sizes. • Keep run boiler to chimney as short as possible. • Use as few elbows as possible. • Slope upward towards chimney at not less than 1/4” per foot. • Use a sealed-in thimble for the chimney connection. • Connect together all sections and/or fittings with s[...]

SIDE-WALL VENTING---IMPORTANT NOTE Two problems arise when side wall venting any oil appliance; 1. There is sometim es an accelerated rate at which soot builds up on the cad-cell, spinner, etc. 2. There is the potential for severe soot damage to the side of the structure in the event that the boiler operates at a high smoke level. This can happen f[...]

INSTALLING THE BOILER Placing The Boiler (OWB-9 – OWB-25) 1. Move the boiler as close as possible to its final location in the crate. 2. Rem ove the two lag screws holding the rear feet to the skid. 3. Rem ove the front jacket panel. Cut the band holding the front of the boiler to the skid. 4. Move the boiler into the final position. 5. Waste Oil[...]
