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 re.
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 res.
3. After the heating requirement has been satis ed, 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 o to purge remaining ue gases.
READ THESE INSTRUCTIONS CAREFULLY AND COMPLETELY BEFORE PROCEEDING WITH THE INSTALLATION.

INSTALLATION SAFETY INSTRUCTIONS
CAUTION: This device must be installed by a quali ed installer in accordance with the manufacturer's installation
instructions. Appliances should have a minimum of 75% combustion e ciency or have a maximum measured ue
gas temperature of 550°F (Stainless steel units maximum temperature rating 650°F US/575°F CA) at the inlet of
the power venter.
1. The power venting system must be installed by a quali ed installer. "Quali ed 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 in the space later in
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 Fuel Gas
Code ANSI 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. Single wall vent pipe (refer to Diagram B) 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 Type Vent Pipe for oil appliances. Refer to national or local codes for guidelines.
5. Disconnect power supply before making wiring connections to prevent electrical shock and
equipment damage.
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- red 30
millivolt power systems MUST be equipped with a spillage switch.
page 2
8. Air ow adjustment MUST be made to ensure appliance e ciency. 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 ANSI Z223.1, Section 8.6.
9. On oil- red and gas- red heating appliances not equipped with a draft hood, a barometric draft control
MUST be installed to regulate proper air ow and uctuations in the system’s air ow during operation.
Fluctuations may come from wind loads on the outlet of the power venter, house de-pressurization during
windy days, and the di erent 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- red 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 ring 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- red draft induced systems require an SWG-4HD or larger. Category III gas- red draft induced systems
require an SWG-5 or larger.
PROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET
1. Calculate the total equivalent feet for each type of tting used in the venting system from Table 2.
2. Calculate the total amount of feet for the straight lengths of vent pipe.
3. Add the equivalent feet for the tting with the total amount of feet of straight lengths. This will
approximate the total equivalent feet of the vent system.

SUDDEN REDUCER OR INCREASER
FOR 3 *RATIOS (d/D)
*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 tting, use the smaller pipe diameter for the
equivalent length gure. 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)

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 packaging and inspect unit for damage. If the packaging has been crushed or
mutilated, check unit very carefully for damage. Rotate blower wheel to ensure 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 ANSI 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. When venting oil red equipment with a Field
Control's CAS-2 series Airboot® kit, the intake air hood can be mounted within 12 inches of the power venter
exhaust.
d. The vent termination of a direct vent appliance with an input of 50,000 BTUs 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 BTUs
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 nished grade.
3. After determining the location of the venting system termination point (See Diagram A), cut a square hole
through the wall at least 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, 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)
