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.

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.

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 = 10"
Step 1 Two 10" 90° elbows @ 18 feet each = 36 ft.
Step 2 Ten 2 foot lengths of 10" pipe = 20 ft.
Step 3 Total equivalent feet = 36 ft. + 20 ft. = 56 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 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.
Page 4
3. After determining the location of the venting system termination point (see
Diagram A
Diagram A), cut a square hole through the wall at least 1" larger than the outer
pipe diameter of the power venter. (See Note Below) Mount the power venter
through the wall, keeping the outer pipe centered in the hole. (See Figure 2&3)
Provide the motor enclosure end of the venter with a temporary support structure.
Fasten the power venter to the outside wall with appropriate fasteners, sealing 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, a minimum
clearance of 1/2" must be maintained between the venter outer pipe and combustible
materials. (See Figure 3) The power venter has a maximum flue gas temperature of
Figure 2
650°F US/575°F Canada at the venter inlet.
2. Remove the screws attaching the damper adjustment lever to the damper shaft and venter body. (See Figure 4)
Rotate the damper to align the damper shaft with the slots in the inner pipe, and slide the shaft up into the slots. Then
mount the backing plate over the outer pipe and route the flexible conduit and pressure switch tube through the holes
provided in the backing plate. Fasten the backing plate to the inside wall with appropriate fasteners. Reposition the
damper and shaft, and re-install damper adjustment lever and screws. The temporary support structure may now be
removed.

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.
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.
Figure 5 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.
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 6)
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: 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 venter
power feed wiring should be protected by an over-current circuit device rated at 20 amperes. In addition, 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.
MOTOR WIRING CONNECTIONS
All pre-assembled units are factory pre-wired for 230 VAC single phase operation. For motor wiring conversion to
115 VAC operation, refer to the motor manufacturer's wiring connection diagram as found on the motor nameplate, and
see instructions below for heater element conversion instructions. THE MOTOR MUST BE WIRED FOR CLOCKWISE
ROTATION WHEN VIEWING THE MOTOR FROM ITS COOLING FAN END as in figures 10 & 11. (CCW when viewing
shaft end)
MOTOR STARTER CONNECTIONS
Refer to Diagram B for connections to the CK-* control kit, venter power feed, and venter motor leads.
WARNING: Do Not reverse hot and neutral wiring if converting to 115VAC operation. Reversal will result in an
unsafe installation and may result in injury, death, and/or equipment damage.
Verify that the overload relay is set to Auto Reset by verifying that the reset mode selector bar
is pushed all the way into the overload relay, and by pushing on the reset push bar. (See Figure 7)
The push bar should be locked in the retracted position by the reset mode selector bar.
IMPORTANT: See instructions on the following page for Motor Overload Relay heater element
installation.
Figure 7
Page 7
MOTOR OVERLOAD RELAY HEATER ELEMENT
All units are shipped with the appropriate heater element
for 230 VAC operation pre-installed in the overload relay.
Please refer to Table 2 for heater element selection
verification. To convert to 115 VAC operation, remove the
230 VAC operation heater element from the Overload
Relay and replace with the supplied 115 VAC heater
element. (See Figure 8) IMPORTANT: VERIFY THAT
THE PROPER HEATER ELEMENT IS INSTALLED IN
THE OVERLOAD RELAY FOR THE PARTICULAR
INSTALLATION. FAILURE TO DO SO MAY RESULT IN
AN UNSAFE INSTALLATION AND MAY CAUSE
INJURY, DEATH, AND/OR EQUIPMENT DAMAGE!
CK-* CONTROL KIT BURNER CONNECTIONS
Refer to appropriate control kit for proper installation instructions.
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 9) 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.

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 burner 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. Motor bearings on the SWG-10, SWG-12, and
SWG-14 are permanently lubricated; no relubrication is required.
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.
