[. . . ] DIAGRAM B DIAGRAM C DIAGRAM D DIAGRAM E 6 IN-FORCER MOUNTING INSTALLER NOTE 1. For easier wiring and servicing maintain 18" clearance from the rear and control sides and 12" from the top of the IN-FORCER. For easier electrical interlock plan for sufficient duct so that the IN-FORCER can be suspended adjacent to the heating equipment that it serves. Do not directly discharge onto water piping or objects that may be affected by temperature extremes. In areas with low temperature extremes it is advisable to insulate ducts or use insulated duct. Do not exceed equivalent duct lengths listed in IN-FORCER Selection Table on Page 3. MODELS PAI-3 & PAI-4 (DIAGRAM F) Verify that overhead support has sufficient strength to hold weight of IN-FORCER. Bend mounting support flanges to the angle best suited to the specific installation. Use perforated strap (installer supplied) and the provided 1/4"-20 x 3/4" hex head bolts and kep nuts to secure strap to the holes in the mounting flanges, (See Diagram F). MODELS PAI-5, PAI-6, PAI-7 (DIAGRAM G) Verify that overhead support has sufficient strength to hold weight of IN-FORCER. The eyebolts may be secured to either the top or bottom of the IN-FORCER casing. Attaching the eyebolts to the bottom allows the IN-FORCER inlet to be positioned to the opposite side, giving the option of a right hand or left-hand inlet pipe connection. On bottom of cabinet install 1/4"-20 x 3/4" hex head bolts, washers and nuts, (See Diagram G). DIAGRAM F DIAGRAM G 2. Connect crimped end of intake duct to the IN-FORCER inlet collar with sheet metal screws. Tape connection to inlet collar and all joints of intake duct to prevent the entry of indoor air. DIAGRAM H 3. The discharge should terminate no closer than 3 feet from a barometric draft control or intake grille of an appliance. If this is not possible terminate on sides or opposite side of appliance intake. Never terminate within 3 feet from the front or intake side of appliance. Discharge duct should also terminate a minimum of 18 inches above floor or other obstructions if perpendicular to them, (See Diag. These clearances are necessary to prevent pilot outages and ensure proper draft control operation. 7 ELECTRICAL All wiring from the IN-FORCER to the appliance must be appropriate Class 1 wiring as follows: installed in rigid metal conduit, intermediate conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable or be otherwise suitably protected from physical damage. The IN-FORCER has a high temperature limit switch to deactivate the system in the event of a mechanical room fire. It also has a fan proving switch to prove operation prior to burner ignition.
