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.

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.

*Reducer or increaser ratio (d/D) small diameter divided 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. (See Figure 1)  
Figure 1  
Example: System Pipe Size = 4"  
Step 1 Two 4" 90° elbows @ 7 feet each = 14 ft.  
Step 2 Ten 2 foot lengths of 4" pipe = 20 ft.  
Step 3 Total equivalent feet = 14 ft. + 20 ft. = 34 ft.  
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 box and inspect unit for damage. If the carton 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.  
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.  
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. The bottom of the vent terminal shall be located at least 12" above finished grade.

Diagram A  
3. After determining the location of the venting system termination point (see  
Diagram A), cut a square hole through the wall 1" larger than the outer pipe  
diameter of the power venter. Mount the power venter through the wall, keeping  
the outer pipe centered in the hole. (See Figure 3) Fasten the power venter to the  
outside wall with appropriate fasteners. Seal the edges of the power venter base  
plate to the wall with a high temperature silicone sealant. DO NOT enclose the  
spaced plates on the power venter body. This will result in reduced cooling of the  
power venter body. Wood or vinyl siding should be cut so that the unit mounts  
directly on the wall board to provide a stable support. If the siding is greater than  
1/2" thick use a spacer plate or board behind the power venter mounting plate.  
(See Figure 2)  
NOTE: If mounting the power venter though a combustible wall material and the flue  
gas temperature is above 400°F at the power venter inlet, line the square hole with a  
piece of corrosion resistant sheet metal or non-combustible material. The liner piece  
should be the same width as the wall section. (See Figure 3) The power venter has a  
maximum flue gas temperature of 550°F at the venter inlet. For installation in wall  
thicknesses over 8 inches, use an SWG Series Though Wall Extension Kit, Model  
PEK.  
Figure 2  
2. Remove the end pipe cover screws on the sides of the outside pipe and remove  
end pipe cover. Then mount the backing plate over the outer pipe and route the  
flexible conduit and pressure switch tube (if applicable) through the holes provided  
in the backing plate. Fasten the backing plate to the inside wall with appropriate  
fasteners. (See Figure 4) Re-install end pipe cover and screws.

Diagram B  
CONNECTING POWER VENTER TO APPLIANCE  
Venting system should be installed and supported in accordance with the National Flue Gas Code A.N.S.I.Z223.1, or in  
accordance with any local codes. A vent pipe connector shall be supported for the design and weight of the material  
employed, to maintain clearances, prevent physical damage and separation of joints. A vent pipe increaser or reducer may  
be required for connecting the power venter to the vent system. If needed, place the reducer close to the power venter.  
Smaller vent pipe sizes than a chimney-vented system may be used for the vent system.  
If mounting venting system near combustible materials, refer to Diagram B for allowable installation clearances.  
Clearances are based on an installation using single wall galvanized steel vent pipe. For metal thickness of galvanized  
steel pipe connectors, refer to NFPA 211 or NFPA 54 Standards for guidelines. If manufactured double wall vent pipe is  
required or used for the installation, clearance should be based on the vent pipes rated clearance. Always check local  
code requirements for code restrictions.  
Route the vent pipe from the appliance to the power venter using a minimum number of elbows as possible. The horizontal  
section of the vent pipe should have a slight upward slope from the appliance to the power venter. For clearances to  
combustible materials, multiple appliance venting and other installation requirements, refer to the National Fuel Gas Code  
A.N.S.I.Z223.1, and/or any applicable local codes or appliance manufacturer's installation instructions.

Use a PEK series extension kit or follow installation method below for a double pipe system. To  
install an outer pipe extension to the SWG power venter, the end pipe cover on the power venter  
must be removed. Then, cut a 1-inch square notch into the vent pipe extension before attaching  
the power venter. (See Figure 5) This allows clearance for the adjustment damper. Install the  
needed pipe extensions and terminate the outer pipe extension with the end pipe cover (see  
Diagram B). The table above shows minimum allowable clearances when using single or double  
pipe systems. When the outer pipe is extended over the inner pipe, use the double pipe  
guidelines when determining clearances. Figure 6 shows how the airflow pattern through an  
SWG reduces the required clearances to combustibles. NOTE: Vent pipe joints should be  
secured with at least (3) three sheet metal screws.

Figure 7  
CLASS B AND CLASS L DOUBLE WALL VENT PIPE INSTALLATION  
(Follow vent pipe manufacturer's listed or recommended clearances from combustible material)  
1. Using a hand crimper or a like device, crimp the inner pipe of the SWG power venter approximately 1" long. (See  
Figure 7)  
2. Attach the vent pipe over the crimped end of the SWG power venter inner pipe.  
3. Secure the vent pipe to the SWG power venter inner pipe with at least (3) three #8 sheet metal screws. Pre-drilling the  
holes through both pipes will allow easier fastening.  
WIRING  
NOTE: Refer to appropriate control kit for proper installation instructions.  
Wire the power venter motor and controls in accordance with the National Electric Code and applicable local codes. UNIT  
MUST BE GROUNDED. Check ground circuit to make certain that the unit has been properly grounded. The wiring should  
be protected by an over-current circuit device rated at 15 amperes. CAUTION MUST be taken to ensure that the wiring  
does not come in contact with any heat source. All line voltage and safety control circuits, between the power venter and  
the appliance, MUST be wired in accordance with the National Electrical Code for Class 1 wiring or equivalent.  
AIR FLOW ADJUSTMENTS  
In order to obtain proper system draft, the power venter has an airflow adjustment damper built in.  
When used in a system with a barometric draft control, this damper should be used to make coarse  
draft adjustments while the barometric should be used for finer adjustments. Loosen the locking  
screw on the air flow adjustment damper on the outer pipe of the power venter. (See Figure 8) Adjust  
the damper to the full open position. Follow appliance manufacturer's procedures for starting the  
heating appliance. Then adjust the thermostat to call for "Heat". After the system has operated for  
several minutes to stabilize flue gas temperatures, check for negative draft or up-draft at the heating  
appliance outlet or air flow into the draft hood. Use a draft gauge, velocity meter or match test  
procedure. Adjust the adjustment damper closed to obtain the minimum air flow required to maintain  
draft. Then increase air flow slightly (10% over minimum air flow rate) to ensure proper venting. For  
oil-fired or gas-fired power burners, adjust draft to proper over-fired draft.  
Figure 8  
If proper draft has been established, tighten the adjustment locking screw. For gas-fired systems, shut off thermostat and  
check for residual heat spilling from draft hood. If this occurs, a post purge timer may be required. If so, use a Field  
Controls PPC-5 Electronic Post Purge or a Control Kit which includes one. Before installing, refer to the General  
Installation Inspection to check for negative pressure problems in the building. If sufficient combustion air for the burner is  
not provided, a flow reversal during the off cycle could occur within the venting system. This may cause combustion  
problems as well as condensation that could block the air pressure sensing tube. It may also contribute to premature  
motor failure. Combustion, and/or make-up air, should be supplied from outside the structure and the air inlet should be on  
the same wall as the power venter discharge. For example, tightly constructed homes and homes retro-fitted from electric  
heated systems are more likely to experience combustion and/or make-up air problems. For further information consult  
"The Field Report-Effects of insufficient combustion air on draft and heating systems". Refer to the appropriate control kit  
installation instructions for pressure switch adjustment procedure and system checkout procedures before operating  
continuously. NOTE: After proper venting has been established, it is recommended that a combustion test on gas and oil  
units, a check for CO levels on gas units, and a smoke test on oil systems be performed to ensure maximum burner  
efficiency. Oil burner air adjustments should be set at a zero to a trace smoke at the highest or recommended CO2%  
setting set by heating equipment manufacturer.

GENERAL INSTALLATION INSPECTION  
Recommended procedures for safety inspection of an appliance in accordance with the National Fuel Gas Code  
A.N.S.I.Z223.1. The following procedure will help evaluate the venting system. It is intended as a guide to aid in  
determining that the venting system is properly installed and is in a safe condition for continuous use. This procedure  
should be recognized as a generalized procedure which cannot anticipate all situations. Accordingly, in some cases,  
deviation from this procedure may be necessary to determine safe operation of the equipment. If it is determined that a  
condition exists which could result in unsafe operation, the appliance should be shut off and the owner advised of the  
unsafe condition. Corrections must be made before the appliance is put into continuous operation. The following steps  
should be followed in making a safety inspection.  
1. Visually inspect the venting system for proper size and determine that there is no flue gas spillage, blockage,  
restriction, leakage, corrosion or other deficiency which could cause an unsafe operation.  
2. Insofar as practical, close all building doors, fireplace dampers, windows and all doors in area in which the appliance is  
located. Turn on clothes dryers, any exhaust fans, such as range hoods and bathroom exhausters so they operate at  
maximum speed. Do not operate a summer exhaust fan. If, after completing Steps 3 through 7 it is believed sufficient  
combustion air is not available, refer to the National Flue Gas Code A.N.S.I.Z223.1, or any applicable local codes for  
guidance.  
3. Place in operation the appliance being inspected. Follow the lighting instructions and adjust thermostat so appliance  
will operate continuously.  
4. Determine that the pilot or burner is operating properly and that the main burner ignition operates satisfactorily, by  
interrupting and re-establishing the electrical power of the appliance in any convenient manner. Test the pilot or burner  
safety device to determine if it is operating properly by extinguishing the pilot or disconnecting the flame safety circuit  
and pressure switch sensing tube from the pressure switch.  
5. Visually determine that the main burner is burning properly; i.e., no floating, lifting or flashbacks. When performing  
smoke test on oil-fired systems, the burner should operate at a zero to a trace smoke. This can indicate reduced  
available combustion air to burner.  
6. If appliances are equipped with high and low flame control or flame modulation, check for proper main burner  
operation at low flame.  
7. Test for spillage at draft hood or barometric draft control opening and burnr inlet air location after 5 minutes of main  
burner operation. Use a draft gauge, flame of a match or candle, smoke from a cigarette, cigar or pipe. If spillage  
occurs, adequate air is not available. Shut off heating appliance thermostat and check for spillage around the draft  
hood, barometric draft control or burner inlet air location after power venter has stopped operation. If a flow reversal is  
noticed, house de-pressurization is occurring and make up air is required. For oil-fired systems, this may be noticed by  
oil fume smell after post purge cycle.  
8. Turn on all fuel burning appliances within the same room so that they will operate at their maximum input. Then repeat  
Steps 5 through 7.  
9. Return doors, windows, exhaust fans, fireplace dampers and any other fuel-burning appliances to their previous  
condition of use.  
MAINTENANCE  
1. Motor: Inspect the motor once a year - motor should rotate freely. To prolong the life of the motor, it must be  
lubricated with six drops of SWG Superlube, Part # 46226200, annually.  
2. Wheel: Inspect the power venter wheel annually to clear any soot, ash or coating which inhibits either rotation or air  
flow. Remove all foreign materials before operating.  
3. Vent System: Inspect all vent connections annually for looseness, for evidence of corrosion and for flue gas leakage.  
Replace, seal or tighten pipe connections if necessary. Check the power venter choke plate to insure it is secured in  
place. Check the barometric draft control, if installed, to insure the gate swings freely.  
4. System Safety Devices: With the heating system operating, disconnect the pressure sensing tube from the pressure  
switch on the CK Kit. This will stop the burner operation. Re-connecting the tube will relight the burner. For 30 millivolt  
operating systems, disconnect one lead of the spill switch circuit from the thermocouple junction block. This will shut  
off the pilot and the burner. Re-connection will allow relighting the pilot.
