Venting - Thermo Products VH8FA119P60B Installation And Operation Manual

B. VENTING:
NOTE: On the VH8F* and VL8F/R* it is possible to rotate the flue elbow (which is factory installed for
vertical discharge) 90° counter clockwise. Only the VH8F flue elbow may also be rotated 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.
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 side casing, remove the 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 to hide the gap around the flue pipe. This trim collar, however, is not
required for operation. Trim collar/gasket part numbers(s) 14132 / 330006.
The VH8F*, VL8F/R* may be vented through a standard correctly sized chimney.
The VH8F* and VL8F/R may also be horizontally vented through a sidewall. A field model
FDVS-67/FOVP-615 side wall vent kit for such applications is available. 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 Sidewall vent kit is set up with a 6 inch diameter vent pipe for the VH8F* and VL8F/R* with concentric
through-the-wall vent termination/inlet air vent hood. For Beckett, the combustion air inlet pipe will be
reduced to 3" diameter with the Beckett sidewall vent kit.
The VH8F* side wall vent may be installed either through the knock-out in the right or left side casing of
the unit or vertically out the top opening of the vestibule. The VL8F/R* side wall vent may only be
installed through the knock-out in the 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.
