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.
PAGE 4
PROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET 1. Calculate the total equivalent feet for each type of fitting used in the venting system from the following chart. 2. Calculate the total amount of feet for the straight lengths of vent pipe. 3. Add the equivalent feet for the fittings with the total amount of feet of straight lengths.

Diagram A 8. Air flow adjustment MUST be made to ensure appliance efficiency. This should be done at the appliance exhaust outlet with a velocity meter, draft gauge or by the "match test procedure". The match test is in accordance with National Fuel Gas Code A.N.S.I.Z223.1, Section 8.6. 9. On heating appliances not equipped with a draft hood, a barometric draft control MUST be installed to regulate proper air flow and fluctuations in the system's air flow during operation.

SIDE WALL VENT HOOD INSTALLATION 1. Use the inside wall plate as a template to mark the hole location. Cut a hole 1 inch larger than the marked hole to facilitate easy installation (See Figure 4) 2. Center vent hood through the hole from outside. Fasten the vent hood to the outside wall with the appropriate type of mounting screws. 3. Fasten the wall end plate to the inside wall with the appropriate type of mounting screws.

GENERAL WIRING INSTRUCTIONS CAUTION: Disconnect electrical power before wiring power venter! Connect line voltage (110/120 VAC) through junction box access hole labelled "120 VAC Only". Connect low voltage control wiring through junction box access hole labelled "24 VAC Control Wiring Only". VENTER MUST BE GROUNDED! Check ground circuit to make certain that venter has been properly grounded.
PAGE 8
AIR FLOW ADJUSTMENTS 1. To properly adjust the venter air flow, loosen the inlet ring screws and open the choke plate approximately 1/2 to 3/4 open. (See Figure 10) Start the heating appliance following the manufacturer specified procedure, and set the thermostat to call for heat. 2. After the system has operated for several minutes to stabilize the exhaust gas temperature, check for air flow at the draft hood or the heating appliance outlet using a velocity meter, draft meter, or match test procedure. 3.

TROUBLESHOOTING TIPS 1. Burner does not fire when thermostat calls for heat. a. Make sure draft tube is securely fastened to the air pressure switch, and is not blocked. b. Check for continuity across pressure switch terminals when venter is operating. c. Check wiring connections between air pressure switch and appliance. 2. Venter does not activate when thermostat calls for heat. a. Check to see if relay closes when thermostat calls for heat. b. Check wiring connections. c.

PV SERIES POWER VENTER: VERTICAL VENTING OPTION Diagram C illustrates correct and incorrect installation of PV series venter in vertical vent configuration (except PVE1200). 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.
