INTRODUCTION This manual is intended to provide recommended instructions for the installation, operation and maintenance of the GROTH Model 77E-AF in-line flame arrester. Any standard procedures and practices developed for a specific plant or process should supersede this manual. Although this manual cannot cover all possible contingencies, following these guidelines will provide safe and reliable flame arrester service. - Page 5 INTEGRATED TEMPERATURE SENSORS Flame arresters rated for short-time burning, which are installed in a scenario with a continuous flow of flammable gas which could lead to a possible extended burning condition, must be fitted with one or more integrated temperature sensors which take into account the intended orientation of the flame arrester. Each such temperature sensor must trigger an emergency function to shut off the flow of gas through the arrester, within half of the rated burn time.

The bases must also withstand the deflagration pressures while conveying the burning vapors and flame front to the element. Depending on the design of the system in which it is used, the arrester bases can include optional ports for thermocouples or pressure monitoring devices. WARNING! Any damage to the flame arrester element, can compromise the ability of the flame arrester to stop a flame front within the arrester performance design specifications. - Page 8 Figure 2: Flame Arrester Assembly - Exploded View CAUTION In a horizontal line, the flame bank assembly should be supported before removing the studs. Use structures and equipment suitable for supporting the component’s weight. 6. Verify that the element openings are not obstructed by viewing a light source through the element passages.
