place. |

The adjustable bolt can be accessed by reaching through the | Figure 23- Decorative Door Trim |
firebox to the back of the unit. See Figure 22. |

The amount to close the restrictor will depend on the vent height. If the vertical height is 20 feet or more, the restrictor can be closed all the way. Anything less will require some setting less than closed. The setting will vary depending on the installation.
Any offsets in a vertical installation will restrict the system and the flue restrictor will not need to be closed as much.
The screws are thread cutters and a power screwdriver is neces- sary to drive the screws into position. See Figure 23.
