Thermo Products OD6FX072DV5R, OD6FA072DV5R, OD6RX072DV5R B. Venting, Rotation Of Front Flue Elbow

The vent connector pipe between the furnace and chimney shall be of equal diameter as the flue outlet of the furnace. The vent connector pipe must be made of 24 gauge (or thicker) corrosion-resistant steel. The vent connector pipe should be as short as possible and installed so that it has a continuous rise from the furnace to the chimney. The horizontal length of a connector to a natural draft chimney or vent serving a single appliance shall not be more than 75 percent of the height of the vertical portion of the chimney or vent above the connector. Elbows should be minimized and the pipe should be joined with metal screws and supported by straps. All horizontal runs of vent connector pipe should be pitched upward a minimum of ¼ inch per foot of run. A thimble should be used to connect the vent connector pipe to the chimney so the pipe may be readily removed in case of inspection or replacement. See Fig. 6 on preceding page.

B. VENTING:

NOTE: On the OD6 it is possible to rotate the flue elbow (which is factory installed for vertical discharge) 90° clockwise or counter clockwise from the vertical position to adapt to various venting systems.

cCAUTION MUST BE TAKEN NOT TO EXCEED 90° ROTATION (OF THE FLUE ELBOW) .

ROTATION OF FRONT FLUE ELBOW:

When an installation requires that the flue exit out the left or right side casing on a front flue unit, remove screw securing the 90 deg. elbow and rotate it 90°. Then, remove knock-out in side casing and extend vent through the opening. The elbow may also be removed and the unit can be vented through the front center panel after removing the knock-out.

A trim collar may be ordered from Thermo Products to hide the gap around the flue pipe. This trim collar, however, is not required for operation. Trim collar/gasket part numbers(s) 14121 / 330073.

The OD6 may be vented through a standard correctly sized chimney.

The OD6 may also be horizontally vented through a side wall. Thermo Products has available the Field model FDVS-45/FVOP-415 side wall vent kit for such applications. When installing the FDVS-45/FVOP- 415 side wall vent kit, outside combustion air must also be applied to the burner. The following table identifies application order information.

Table 2: Side wall vent kits

The Field vent kit is set up with 4 inch diameter vent pipe with concentric through-the-wall vent termination/inlet air vent hood. The combustion air inlet pipe diameter is also 4 inch diameter. For Riello, the combustion air inlet pipe will be reduced to 3 inch diameter with the Riello side wall vent kit. For Beckett, the combustion air inlet pipe will be reduced to 3” diameter with the Beckett side wall vent kit.

The side wall vent may be installed either through the lower knock-out on the right and left side casing of the unit or vertically out the top opening of the vestibule.
