[. . . ] Measure and cut an appropriate length of tubing to reach from the fitting marked "warning" to the burner of the water heater. Conduct a gas leakage test of the aluminum tubing as outlined in the 1988 (or latest) edition of NFPA 54, ANSI Z223. 1, part 4. All vent system leaks must be sealed prior to installation of a power venter. A vent system incorporating a Tjernlund VH1 Series vent hood should not exceed 575 F. Termination of a sidewall vent system with a device other than the Tjernlund VH1 Series vent hood could affect system performance and result in a possible safety hazard. Plan the vent system layout to avoid the possibility of accidental contact with wiring or plumbing inside of walls. Installation must be done by one experienced and familiar with venting of combustion appliances. o 5 VENT HOOD INSTALLATION 1. Verify that proposed Vent Hood location will conform to "Vent Hood Termination Clearances" on page 5. POWER VENTER INSTALLATION CODE REQUIREMENTS Power Venter installation must be in accordance with the following requirements of the National Fuel Gas Code: (ANSI Z223. 1) · All portions of the vent system under positive pressure during operation (on the outlet side of the Power Venter) shall be designed and installed so as to prevent leakage of flue or vent gases into a building. · All appliances must enter the vent system on the inlet side of the Power Venter. · Provision shall be made to interlock the appliance(s) to prevent the flow of gas to the main burners when the draft system is not performing so as to satisfy the operating requirements of the equipment for safe performance. The Power Venter operates on 110/115 VAC, therefore a grounded outlet must be within reach of the six foot power cord supplied with Power Venter. The flexible power cord supplied with the unit may only be used where local codes permit. If local codes do not permit the use of flexible power cord, follow steps below. Remove the electrical box cover, flexible cord and strain relief from the enclosure. Install suitable conduit fitting in enclosure and splice field wiring into existing wiring using code authorized method (wire nuts, etc. ). Replace electrical box cover. 7 TYPICAL INSTALLATION ACTUATING AND SAFETY CONTROL CIRCUIT CONNECTIONS 1. Push the black lead from the 6' 18/2 cable onto the common terminal of the gas pressure switch. Push the remaining black lead from the 6' 18/2 cable onto one of the terminals on the solenoid valve. Push the yellow lead from the 25' control cable onto the remaining terminal on the solenoid valve. Push the red lead from the 25' control cable onto the piggyback terminal joined with common on the gas pressure switch. Push the blue lead from the 25' control cable onto the normally open terminal on the gas pressure switch. [. . . ] All receipts should include the date code of the Power Venter to ensure that the defective component corresponds with the complete unit. If unable to determine faulty component, contact your Tjernlund distributor or Tjernlund Products Technical Customer Service Department at 1-800-255-4208 for troubleshooting assistance. 2. ) After the faulty component is determined, return it to your Tjernlund distributor for replacement. If Power Venter date code is older than 18 months you will need to provide a copy of the original installation receipt to your distributor. [. . . ]
