The solenoid valve is installed in the gas supply piping to the water heater's thermostat/valve. To save installation time, do not pipe gas to water heater before installing the gas solenoid valve. OPTIONAL PILOT SAVER KIT AVAILABLE The optional Pilot Saver Kit (P/N: 950-2061) allows for Solenoid Valve to be installed in 1/2" burner gas line from water heater gas valve to burner, eliminating pilot outages caused by power interruptions. Rev. [. . . ] Power Venter should be installed as close to the termination of the vent system as possible to prevent flue gas leakage. Power Venter must be installed with the motor shaft horizontal to prevent motor bearing wear. If installing the VP-2, 3" vent pipe may be used from the water heater to the Power Venter. If the flue outlet is larger than 3", install a tapered reducer directly after the draft hood of the water heater. If installing the VP-3, 4" vent pipe may be used from the water heater to the Power Venter. If the flue outlet is larger than 4", install a tapered reducer directly after the draft hood of the water heater. NOTE: All reducers and vent pipe are to be supplied by the installer and are available from your local heating wholesaler. The equivalent vent pipe length of elbows and straight pipe must be calculated. The total equivalent length must not exceed 75 feet with no more than 25 equivalent feet in elbows. TAPERED REDUCER 6" CLEARANCE FROM VENTER HOUSING 6 MOUNTING POWER VENTER 1. To facilitate installation and reduce vibration, we have included 2 mounting brackets, 2 rubber isolators and 2 rubber grommets. One of the brackets may be used temporarily as a "third hand" to support the Power Venter while positioning it for permanent installation. NOTE: The Power Venter may be mounted in any position as long as the shaft of the motor remains horizontal. VP-2 MOUNTING VP-3 MOUNTING 2. Sections of vent pipe are permitted between Power Vent and Vent Hood but all connections after the Power Venter will be under a positive pressure during operation. These connections must be sealed with high temperature silicone sealant or aluminum vent pipe tape supplied by installer. Using the holes as a guide, attach vent pipe to inlet collar using sheet metal screws. Install properly sized vent pipe sections from Power Venter inlet to appliance outlet avoiding elbows wherever possible and using only tapered transitions. Support vent pipe in accordance with vent manufacturer's instructions. ELECTRICAL Route the 25' control cable supplied with the Power Venter back to the water heater controls along the ceiling joists, taking care not to come closer than 6" to the vent pipe or any other potentially hot surface. In most cases, the gas supply line may be used as a routing path from the ceiling to the water heater controls, the supplied nylon straps may be used to secure the cable. NOTE: If the distance between the Power Venter and the heater controls is greater than the length of the cable, splice a section of 3 conductor PVC sheathed, 105 degree C thermostat cable to the supplied cable. An NEC approved accessible junction box must be used to contain the splice. Splices shall be made mechanically secure and insulated with tape or fixture type splicing connectors may be employed. Strain relief hardware contained within the NEC approved junction box shall be utilized. [. . . ] Credit or replacement will only be issued to a Tjernlund distributor after the defective part has been returned prepaid to Tjernlund.
