Initial Installation

QUALIFIED INSTALLERS ONLY

FREESTANDING DRAFTHOOD ADAPTOR:

This Drafthood Adaptor is a complete assembly and is ready to fit onto your Westport in a vertical vent application only. With the Drafthood Adaptor correctly installed and wired to the gas control valve. Your Direct Vent Fireplace can be vented like a B-Vent Fireplace.

INSTALLATION:

WARNING: This Freestanding Drafthood Adaptor must be fitted by a qualified service technician.

Step 1

Remove the Drafthood Adaptor from the packaging. Ensure the unit and wire harness are undamaged. If there is damage contact your dealer, distributor, or courier company before starting this installation.

Step 2

Install the adaptor so the wires exit to the rear of the fireplace. Slide the Drafthood Adaptor over the outlet pipe of the fireplace until the bottom of the adaptor collar stops on the top of the outlet. The Drafthood Adaptor must be safely secured to the vent flanges with either self-tapping screws and/or high temperature sealant.

WARNING: During the fitting of the Drafthood Adaptor, ensure that the wires are not pinched between the adaptor and the collar and/or flue outlet. Ensure that the opening of the Drafthood Adaptor is not blocked or obstructed.

Step 3

Being careful not to run any wiring tight across metal edges; connect them to the valve and “ON/OFF” switch (refer to Figure 39).

Step 4

Adjust the restrictor plate to position 2.5 of 5. See the vent restrictor settings in the instruction manual.

Step 5

Adjust the embers on the burner so they don’t cover the burner ports.
