GENERAL SYSTEM INFORMATION
Designed for operation with natural gas, LP gas and #2 fuel oil appliances.
1.The thermostat (wall thermostat or aquastat) calls for heat and energizes a relay which activates the power venter. 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 fire.
2.For millivolt controlled water heaters using the CK-20 Series Control Kit, the gas valve pressure switch activates the power venter at the same time as the burner fires.
3.After the heating requirement has been satisfied, the thermostat circuit will open and de-activate the burner and power venter circuit.
4.For venting systems equipped with a post purge device, the power venter operates for a period of time after the burner has shut off to purge remaining flue gases.
DO NOT DESTROY
THESE INSTRUCTIONS MUST REMAIN WITH EQUIPMENT

INSTALLATION SAFETY INSTRUCTIONS
CAUTION: This device must be installed by a qualified installer in accordance with the manufacturer's installation instructions. Appliances should have a minimum of 70% combustion efficiency or have a maximum measured flue gas temperature of 650°F US/575°F CAN) at the inlet of the power venter.
1.The power venting system must be installed by a qualified installer. "Qualified Installer" shall mean an individual who has been properly trained or a licensed installer. The installer must write or imprint his name, phone number and date of installation on the installation tag. The tag should be attached to the power venting system control kit box or power venter unit. Recording burner and venting system initial operational information is strongly recommended as a guide for service or burner tune-up. Enter this on the back page of this manual.
2.Safety inspection of a venting system should be performed before and after installing a power venting system on an existing or new appliance. Procedures to follow are those recommended by the National Flue Gas Code A.N.S.I.Z223.1, or refer to the General Installation Inspection section of this manual.
3.Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls.
4.Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage.
5.Single wall vent pipe may be used to join an appliance to the venting system, but if proper clearances cannot be maintained from combustible materials, Class B Vent Pipe should be used for gas appliances and Class L Vent Pipe for oil appliances. Refer to national and local codes for guidelines. It is the responsibility of the installer to verify that the vent pipe system is installed in accordance with all applicable national and local codes.
6.This equipment is designed to overcome minor negative pressure conditions. To ensure extreme negative pressure does not exist, follow the General Installation Inspection section of this manual.
7.Heating appliances equipped with draft hoods, such as boilers or furnaces, LP gas appliances and Natural gas appliances SHOULD have a secondary spillage switch installed. On appliances without draft hoods, it is recommended that a secondary safety switch such as a WMO-1, GSK, FTS, or TSP-1 be used. Gas-fired 30 millivolt power systems MUST be equipped with a spillage switch.
8.Air flow adjustment MUST be made to ensure appliance efficiency. This should be done at the appliance exhaust outlet with a velocity meter, draft gauge or by "match test procedure". A match test is in accordance with National Fuel Gas Code A.N.S.I.Z223.1, Section 8.6.
9.On oil-fired and gas-fired heating appliances not equipped with a draft hood, a barometric draft control MUST be installed to regulate proper air flow and fluctuations in the system's air flow during operation. Fluctuations may come from wind loads on the outlet of the power venter, house de-pressurization during windy days and the different house ventilation requirements between summer and winter operation. For gas appliances, use a Field Controls Type MG-1 Barometric Draft Control. For oil appliances use a Field Controls Type M or RC Barometric Draft Control. Gas-fired draft induced systems should have a single-acting barometric draft control installed.

*Rating at 100 psi. Sizing based on appliance maximum input rate not actual firing rate. **Do not exceed maximum BTU/HR input rating or maximum oil GPH input. For multiple venting system applications, add the input for each appliance. Category I gas-fired draft induced systems require an SWGII-4HD or larger. Category III gas-fired draft induced systems require an SWGII-5 or larger.

PROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET
1.Calculate the total equivalent feet for each type of fitting used in the venting system from the chart below.
2.Calculate the total amount of feet for the straight lengths of vent pipe.
3.Add the equivalent feet for the fitting with the total amount of feet of straight lengths. This will approximate the total equivalent feet of the vent system.

INSTALLATION
CAUTION: Failure to install, maintain and/or operate the power venting system in accordance with manufacturer's instructions will result in conditions which may produce bodily injury and/or property damage.
1.Remove power venter from packaging and inspect unit for damage. If the packaging has been crushed or mutilated, check unit very carefully for damage. Rotate blower wheel to insure that the motor and blower wheel rotate freely. DO NOT install if any damage is apparent. Refer to unit sizing chart to check proper venting sizing.
2.Location of the termination of the venting system should be installed in accordance with the National Fuel Gas Code A.N.S.I.Z223.1, manufacturer's recommendations and/or local codes which are applicable. See requirements below or refer to installation location, Diagram A, for typical locations.
a.The exit termination of mechanical draft systems shall not be less than 7' above grade when located adjacent to public walkways, although IT IS RECOMMENDED THAT THE SWG-10, SWG-12, AND SWG-14 BE MOUNTED
NOT LESS THAN 10' ABOVE GRADE WHEN LOCATED ADJACENT TO PUBLIC WALKWAYS.
b.A venting system shall terminate at least 3' above any forced air inlet located within 10'.
c.The venting system of other than a direct vent appliance shall terminate at least 4' below, 4' horizontally from or 1' above any door, window or gravity air inlet into the building.
d.The vent termination of a direct vent appliance with an input of 50,000 BTU's per hour or less, shall be located at least 9" from any opening through which vented gases could enter the building. With an input over 50,000 BTU's per hour, a 12" termination clearance shall be required. THE SWG-10, SWG-12, AND SWG-14 MUST BE
PROVIDED WITH A 12" MINIMUM CLEARANCE ABOVE ANY OPENING THROUGH WHICH VENTED GASES COULD ENTER THE BUILDING.
e.The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped structure.
f.The vent termination should not be mounted directly above, or within 3' horizontally from an oil tank vent or gas meter.
g.ANSI Z223.2 requires that: "The bottom of the vent terminal shall be located at least 12" above finished grade", although IT IS RECOMMENDED THAT THE SWG-10, SWG-12, AND SWG-14 BE MOUNTED AT LEAST 48"
ABOVE FINISHED GRADE.
