4.Thread the air terminal connector / vent pipe assembly down through the roof. The air terminal must be located vertically and plumb. Attach the air terminal connector to the roof support, ensuring that the top of the air terminal is 16” above the highest point that it penetrates the roof. Figure 27. DO NOT CLAMP THE FLEXIBLE VENT PIPE.

6. Aligning the seams of the terminal and air terminal connector, place the terminal over the air terminal
connector making sure the vent pipe goes into the hole in the terminal. Secure with the three screws provided. Figure 27.
7.Apply a heavy bead of weatherproof caulking 2" above the flashing. Note: Maintain a minimum 2” space between the air inlet base and the storm collar. Install the storm collar around the air terminal and slide down to the caulking. Tighten to ensure that a

FIREPLACE VENT CONNECTION
1.Install the 4" flexible vent pipe to the fireplace. Secure with 3 screws and flat washers. Seal the joint and screw holes using the high temperature sealant
2.Install the 7" flexible vent pipe to the fireplace. Attach and seal the joints using the high temperature sealant

1. Move the fireplace into position. Measure the vent length required between terminal and fireplace taking into account the additional length needed for the finished wall surface and any 1¼" overlaps between vent-
ing components. |

3. Holding the air terminal (lettering in an upright, readable position), insert into | SEALANT |
both vent pipes with a twisting motion to ensure that both the terminal sleeves engage |

into the vent pipes and the sealant. Secure the terminal to the exterior wall and make weather tight by sealing with caulking (not supplied).
The air terminal mounting plate may be recessed into the exterior wall or siding by 1½", the depth of the return flange.
