(Outdoor Mounted Power Venters for Oil & Gas) SWG Power Venter Gas and oil heating appliances generate heat through the combustion of fuel. The heat is transferred through the heat exchanger and distributed to the conditioned space. The products of combustion, however, must be vented safely out of the structure. In a conventional chimney, venting is achieved by the natural lifting action of the hot combustion gas.
(Outdoor Mounted Power (Sizing The&Venter) Gas) Venters for Oil SWG Power Venter Size the SWG venter based on the input firing rate of the appliance. If the power venter is being used to vent multiple appliances, add the input firing rates for each appliance and use that total to size the venter. Knowing the total input BTU/hr. for gas, or GPH for oil, the venter can be sized from Table 1. Select the venter rated closest to the total input BTU or GPH for installation.
SWG Power Venter (Planning the Vent System) Location of the termination of the venting system should comply with the National Fuel Gas Code, ANSI Z223.1, manufacturer’s recommendations and/or applicable local codes. See Diagram for typical terminal locations. A. The exit termination of a mechanical draft system must not be less than 7’ above grade when located adjacent to a public walkway.* B.
SWG Power Venter (Clearance to Combustibles) If mounting the venting system near combustible materials, refer to Diagram A for allowable installation clearances. Clearances are based on an installation using single wall galvanized steel vent pipe. If manufactured double wall vent pipe is required or used for the installation, clearance should be based on the vent pipe’s rated clearance. Always check local code requirements for code restrictions.

PV (Indoor Mounted Power Venters for Oil & Gas) Power Venters 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. Accessories SWH Vent Hoods Designed for standard vent pipe and Class B type double-wall (BVent) connection. Provides proper clearance between flue gas stream and wall combustibles. Available in 3" through 8" sizes.

Vent Hoods Aluminum Construction All Field Vent Hoods are made of heavy gauge aluminum and can be used with natural gas, LP gas or oil-fired equipment. There are five diameters ranging from 3” to 8”. The concentric pipe, angled outlet deflectors, and spaced plate design allow for better heat dissipation. This type of construction minimizes the effects of heat on the outside wall. The angled hood design reduces the effects of wind on the venting system. The inner and outer pipe are a continuous structure.
Vent Caps The Star-Kap® is the only vent cap that is not required to be two feet higher than any structure within ten feet when used on detached or lean-to buildings that house heating equipment outside of the living space. The unique design of the aluminized Star-Kap Vent Cap prevents downdrafts and assists the vent in drawing off and exhausting waste gases regardless of wind direction. The Star-Kap can be used to vent gas or oil-fired boilers, furnaces, water heaters and more.
Thermal Safety Switches Our thermal safety switches efficiently detect flue gas spillage due to a blocked flue, continuous down drafting or inadequate draft condition. With the safety switch wired in series with the burner circuit, the switch Models will de-energize the system’s burner or burner control once it senses the spillage of hot flue gases. Available for gas-fired and oil-fired applications. Typical Applications • FTS-4 & FTS-6 FTS Designed for use on large gas furnaces and boilers.
Thermal Safety Switches When to use a Thermal Safety Switch How Thermal Safety Switches Work The Thermal Safety Switch detects the increased heat generated by the flue gas spillage and deactivates the furnace or boiler. It will not allow the burner to restart until the switch has been manually reset. Model Field Part Contact No. Material Load-Rating On Barometric Draft Controls and draft hoods to detect flue gas spillage and deactivate oil and gas burners.
Eliminator ® Foundation Vent Fan Eliminate Moisture In Crawl Spaces Reduce Fungus, Dry Rot and Termite Potential The Eliminator® Foundation Vent Fan is a motorized fan designed for circulating outside air through the crawl space of a structure to reduce moisture problems. Moisture causes dry rot and fungus growth and increases the potential for termite infestation. With the Eliminator, air changes are increased dramatically for better moisture removal and control.
Power Venter Service Guide I. VISUALLY INSPECT THE GENERAL SYSTEM OPERATION: 1. The thermostat (wall thermostat, or aquastat) calls for heat, starting venter motor. 2. After the venter motor has come up to speed, the pressure switch closes. This closes the circuit to the burner and allows the burner to operate. This occurs in approximately 1 to 2 seconds. 3. After the heating requirement is satisfied, the thermostat circuit opens and deactivates the burner and power venter circuit. 4.
Power Venter Service Guide III. SYSTEM SETUP AND TESTING: (Continued) 6. Once proper draft is achieved, measure CO2 and smoke level. If necessary, adjust the intake airflow at the burner to obtain the highest possible CO2 reading with a zero smoke reading. As the intake airflow is increased or decreased, the draft may change. Repeat steps 3 through 6 to re-adjust the draft control and choke plate before attempting any other adjustments. 7.
