46245701 Field Controls 46245701 PVG-100 4" 24V Power Venter For Gas Systems (Pressure switch and post purge controls are included)

Field Controls 46245701 PVG-100 4" 24V Power Venter For Gas Systems (Pressure switch and post purge controls are included)

What's Included 1- PVG-100 Power Venter with pre-wired integral 24 VAC Relay/Timer, factory set Draft Proving Switch, and direct access Terminal Blocks. 1- Installation Instruction Sheet Optional System Components NOT INCLUDED Side Wall Vent Hood (See SWH-4) Spill Switches (See GSK-3 or GSK-4) Barometric Draft Control (See 4" MG1) Included is one ETL LISTED power venter to be used for side wall venting of a single 24 VAC controlled furnace, boiler, or water heater which burns natural or LP gas. The PVG may also be used to vent a single 24 VAC controlled gas fired furnace or boiler and a 30 millivolt residential gas fired water heater. The indoor mounted PVG and PVO Power Venters provide an economical power venting system for gas and oil appliances. All controls are built into these units. A Vent Hood is required to terminate the vent system.

How PV Series Venters Work 1. Thermostat or aquastat calls for heat and starts the Power Venter. 2. The Pressure Switch senses sufficient air flow and allows burner(s) to start. 3. The Power Venter draws combustion air through the system and forces gases outside through an external Vent Hood. 4. Draft Hood or Barometric Draft Control between the appliance(s) and the Power Venter maintains consistent air flow.< 5. After the thermostat is satisfied, the burner shuts down and the Post Purge Control clears the venting system of combustion gases. 6. The Power Venter shuts down. Can Be Used To Replace Tjernlund HSUL-J, HST-J, HSJ PVG's include a post purge control HSUL's do not

PROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET 1.Calculate 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.

*Reducer or increaser ratio (d/D) small diameter divided by the larger diameter.
Example: 4" to 8" reducer, the reducer ratio is d/D = 4⁄8 = 1⁄2. To estimate the equivalent foot length for the fitting, use the smaller pipe diameter for the equivalent length figure. Example: 4" to 8" reducer; the reducer ratio is 1⁄2 and the smaller pipe diameter is 4". So, from the chart, the equivalent feet would be 7 feet.
Example: System Pipe Size = 4" Step 1 2 – 90° Elbows (4") = 14 Ft. Step 2 10 - 2 Ft. Lengths of 4" Pipe = 20 Ft. Step 3 Total Equivalent Feet = 14 Ft. + 20 Ft. = 34 Ft.
