Thermo Products OH6FA072DV4R Side Wall Venting Application Order Information, A. Venting, Burner

All installations and services must be performed by qualified service personnel.

A. VENTING:

NOTE: On the OH6FA072D*** it is possible to rotate the flue elbow (which is factory installed for vertical discharge) 90° counterclockwise from the vertical position to adapt to various venting systems.

cCAUTION MUST BE TAKEN NOT TO EXCEED 90° ROTATION (OF THE FLUE ELBOW) COUNTERCLOCKWISE OR RIGHT FROM THE VERTICAL POSITION.

ROTATION OF FRONT FLUE ELBOW

When an installation requires that the flue exit out the left hand side casing on a front flue unit, remove screw securing the 90 deg. elbow and rotate it 90° counterclockwise. Then, remove knock-out in side casing and extend vent through the opening.

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.

NOTE: ROTATION OF FLUE PIPE IS ONLY ALLOWED FOR LEFT HAND SIDE VENTING APPLICATIONS.

The OH6FA072D*** may be vented through a standard correctly sized chimney.

The OH6FA072D*** 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.
