Install exhaustline as short as possible to minimize back pressure. When the gases being sampled are at an elevatedtemperature, the detector and sample lines should be maintained above the "dewpoint" of the vapors beingsampled to avoid condensation. Install the detector assembly and sample lines as close as possible to theheated source. If contact with the heat source is not possible, the sample line and reaction chamber should beheated-traced with steam or electrical heaters as desired.2-7WARNING AND ALARM CIRCUIT MODIFICATIONSAs manufactured, each control module is provided with a RESET pushbutton23-96177/1/762-37
