GENERAL WIRING INSTRUCTIONS

CAUTION: Disconnect electrical power before wiring power venter!

Connect line voltage (110/120 VAC) through junction box access hole labeled "120 VAC Only". Connect low voltage control wiring through junction box access hole labeled "24 VAC Control Wiring Only". VENTER MUST BE GROUNDED! Check ground circuit to make certain that venter has been properly grounded. The wiring must be protected by an over current protection circuit such as a fuse or circuit breaker rated at 15 amperes. Prevent wiring contact with any heat source.

IMPORTANT: The PVU-300 is shipped with the yellow mode wire connected to the 120VAC terminal. This is correct for 120VAC control (typical oil-fired). For 24VAC control (typical gas fired) the yellow mode wire must be disconnected from the 120VAC terminal and reconnected to the 24VAC terminal (see wiring diagrams).

NOTE: Wire the venter in accordance with the National Electrical Code and applicable local codes. Refer to Diagrams C and D for proper wiring specifications for a 24VAC Gas or 120VAC Oil fired appliance.
