POWER VENTER SIZING In order to choose the correct size power venter for a particular installation, the total input firing rate and total equivalent length of vent pipe to be used must be known. Refer to Table 2 to determine the maximum allowable equivalent feet of pipe for each model used with the pipe diameters shown. When venting multiple appliances, add the input of each appliance to determine the total input. Always choose a power venter that is capable of handling more than the system requires.

Diagram A INSTALLATION SAFETY INSTRUCTIONS CAUTION: This device must be installed by a qualified installer in accordance with the manufacturer's installation instructions. Appliances should have a minimum of 75% combustion efficiency or have a maximum measured flue gas temperature of 550°F at the inlet of the venter. 1. The power venting system must be installed by a qualified installer. "Qualified Installer" shall mean an individual who has been properly trained or a licensed installer.

MULTIPLE APPLIANCE SYSTEMS When using one PVO power venter to common vent more than one appliance, a Control Kit is required for each additional appliance. 1. Connect the negative pressure port of each air pressure fan proving switch on all Control Kits being used to the provided tee mounted on the PVO. (See Figure 4) 2. Remove the cap from the branch of the tee and use the ferrule and compression nut provided in the small envelope with the PVO to attach the connecting tube. 3.

PRESSURE SWITCH ADJUSTMENT 1. With the venter air flow set and the appliance operating at the best operating efficiency, adjust the pressure switch by rotating the adjustment screw clockwise until the burner shuts off. 2. Rotate the adjustment screw counterclockwise until the burner fires. 3. Rotate the adjustment screw an additional 1 ⁄4 turn counterclockwise to ensure proper switch setting. (See Figure 6) Figure 6 POST PURGE TIMER ADJUSTMENT To adjust the post purge time, refer to Figures 7 & 8.

GENERAL INSTALLATION INSPECTION Follow recommended procedures for safety inspection of a heating appliance in accordance with the National Fuel Gas Code ANSI Z223.1. The following procedure will help in evaluation of the venting system. It is intended as a guide to aid in determining that the appliance is properly installed and is in a safe condition for continuous use. This is a generalized procedure which cannot anticipate all situations.

PV SERIES POWER VENTER: VERTICAL VENTING OPTION Diagram D illustrates correct and incorrect installation of PV series venter in vertical vent configuration (except PVE-1200). The correct installation maintains the required vertical position of the pressure switch; the incorrect installation does not. The following conditions must also be observed: • Natural gas, LP gas or #2 fuel oil appliance rated at 75% or greater non-condensing type of appliance.
