Thermo Products OL6RA072D48(B/R) Rotation Of Front Flue Elbow, C. Draft Regulators

NOTE: On the OL6 it is possible to rotate the flue elbow (which is factory installed for vertical discharge) 90° counter clockwise from the vertical position to adapt to various venting systems.

Notice: Blocked Vent Switch Installation

The blocked vent switch kit must be installed to comply with CAN STD B140.4 where applicable. For installation instructions see AOPS2687 kit.

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 side casing, remove screw securing the 90 deg. elbow and rotate it 90°. 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 for OL6.

The OL6 may be vented through a standard correctly sized chimney.

The OL6 may also be horizontally vented through a sidewall. Thermo Products has available the Field model FDVS-45/FOVP-415 side wall vent kit for such applications. When installing the sidewall vent kit, outside combustion air must also be applied to the burner. The following table identifies application order information.

Table 2: Sidewall vent kits

The Field vent kit is set up with 4 inch diameter vent pipe for OL6 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 sidewall vent kit. For Beckett, the combustion air inlet pipe will be reduced to 3” diameter with the Beckett sidewall vent kit.

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

The combustion air inlet can be installed through either the lower left side casing knockout or the lower right side casing knockout.

C. DRAFT REGULATORS:

Note: Do not use with Direct Vent application.

A draft regulator is supplied with the furnace and should be installed according to the regulator manufacturers recommendations. With the burner operating, use a draft gauge to adjust the regulator to the proper setting. (refer to the instructions enclosed with draft regulator to adjust to the proper setting). When the burner air supply and draft are properly adjusted, the over fire draft should be a negative (-).01"
