Installation, Operation, And Service Instructions 19

Placing The Boiler (OWB-9 – OWB-25)

1. Move the boiler as close as possible to its final location in the crate.

2. Remove the two lag screws holding the rear feet to the skid.

3. Remove 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 Piping: USE ONLY 3/8” nominal ID copper tubing with flare fittings only on the

oil suction from the tank to the oil pump and oil pump to burner. DO NOT use ferrule

fittings or teflon tape on any pipe fittings. Keep suction line approximately 6” from

bottom of oil tank to prevent suction of sludge (Figure 11). Use only an inside oil storage

tank. Do Not draw from an outside tank, especially not an underground tank directly to

burner. A separate transfer pump from an outside tank with proper filtration to the inside

supply tank is acceptable.

6. The fuel pump included with burner is to be mounted at tank level or below. PUMP MUST

BE MOUNTED HORIZONTAL AND LOCATED NEXT TO WASTE OIL SUPPLY TANK.

Figure 11.

The over fire draft should be minimum of -0.02 or more. Refer to Table 2 for minimum

breeching sizes. Breeching run should be as short as possible with as few elbows a

practical. Unless marginal draft conditions exist, a brametric draft control must be

installed in the breeching and should be approximately 18 inches from the boiler

breeching connection. Breeching should not project into the chimney beyond the inside

wall of the chimney. Connect the breeching to the chimney with a thimble or slip joint to

facilitate cleaning. See Figure 12.
