Housing Installation

.
Insert the inlet and exhaust tube receptors of the housing base into the two holes
previously cut in the duct.
6. Using the four #8 self-tapping sheet metal screws provided in the accessory kit,
locate the four mounting hole locations that are marked inside on the duct
housing plastic (Detector Chamber marked “MTG”). Drill the four self-tapping
screws through the housing plastic and duct sheet metal to secure the duct
housing (no pre-drilling is required). Torque screws 10-12 inch-pounds.
Inlet Tube Installation (See Figures 9 and 10)
7. Install the inlet tube by inserting the rubber plug end of the tube into the
upstream tube receptor located in the rear of the duct housing. The inlet tube
must be installed through the hole in the housing corner next to the smoke
port/air flow test holes. Place the tube retainer (supplied) over the inlet tube so
that the tab on the tube retainer goes into the slot on the inlet tube. Make sure
the tube retainer is in the proper orientation so that the holes in the inlet tube face
upstream into the airflow. The tab on the inlet tube retainer bracket indicates the
inlet hole side of the pipe.
