Thermo Products OHFA199DV5R, OHFA199DV5B operation manual Venting

Page 13

B. VENTING:

NOTE: On the OH6 & OH8 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. The OH8 flue elbow can also be rotated 90° clockwise.

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.

CAUTION 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 OH8 only) 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 OH6 and 14132 / 330006 for OH8.

The OH6 & OH8 may be vented through a standard correctly sized chimney.

The OH6 & OH8 may also be horizontally vented through a sidewall. Thermo Products has available the Field model FDVS-45/FOVP-415 and FDVS-67/FOVP-615 side wall vent kits for such applications. When installing the sidewall vent kits, 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 OH6 and 6 inch diameter vent pipe for the OH8 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 the either the lower left side casing knockout or the lower right side casing knockout.
