DESCRIPTION
The SS2G is a mechanical vent system designed and listed for use with natural draft gas heating equipment. It is factory assembled and wired. The SS2G automatically vents the flue gases from heating equipment to the outdoors. By recirculating indoor air
with a cooling fan, surrounding combustible materials remain at safe temperatures. After each burner cycle the SS2G will continue
to operate for a nonadjustable timed period of approximately 45 seconds to purge the heater and vent of residual flue gases. The
SS2G features a safety system consisting of a Fan Proving Switch and a High Limit temperature control. These devices monitor
the SS2G’s performance and will interrupt the main burner if a venting malfunction is detected.
APPLICATION TABLE
Verify that the total BTU/hr. input of the heating appliance(s) falls within the inputs listed below. The BTU/hr. capacity range is
based on a maximum of 50 equivalent feet. To determine equivalent feet, add the total length of straight vent pipe plus 10 feet for
each 90 degree elbow and 5 feet for each 45 degree elbow. Vent runs of over 15 linear feet require the use of an approved, insulated vent connector to prevent problems related to condensation.
The SS2G Vent System may only be used on Natural or LP gas fired appliances.

GENERAL INFORMATION
Each SS2G is electrically factory line tested before shipment.
After opening carton, inspect thoroughly for hidden damage. Impeller should rotate freely. If any damage is found notify freight
carrier and your distributor immediately and file a concealed damage claim.
INSTALLATION RESTRICTIONS
1. The SS2G may not be installed on condensing appliances.
2. The SS2G may only be installed on appliances equipped with a draft hood, draft diverter or barometric draft control.
3. The SS2G shall not be installed where flue gas temperatures exceed 650oF at its inlet. Flue gas temperature verification:
A) After 15 minutes of operation, measure flue gas temperature to verify it is not more than 650oF at SS2G inlet.
4. The electrical load controlled through the Fan Proving Switch must not exceed its nameplate ratings.
5. Vent runs of over 15 linear feet require the use of an approved, insulated vent connector to prevent problems related to condensation.
Improper installation, adjustment, alterations, service or maintenance can cause injury, property damage or death. Refer to this
manual. For assistance or additional information consult a qualified installer, service agency or the equipment supplier.
Do not exceed the recommended input range of the SS2G. Under no circumstances shall the minimum draft adjustment be used
for the larger input range of this product. Improper adjustment may result in the dispersion of flue products (carbon monoxide)
into the building interior causing carbon monoxide poisoning or death.
CAUTIONS
The Power Venter must be installed by a qualified installer in accordance with these instructions and all local codes or in their
absence in accordance with the latest edition of The National Fuel Gas Code (NFPA #54), the latest edition of the National
Electrical Code (NFPA#70) and the Occupational Safety and Health Act (OSHA) when applicable. Improper installation can create
a hazardous condition such as an explosion, fire, electrical shock or carbon monoxide poisoning resulting in property damage, personal injury or death.
2
Disconnect the power supply when making wiring connections or when working around the fan wheel and motor. Failure to do so
3
can result in electrical shock, personal injury, death or property damage.
1. “Qualified Installer” shall mean an individual properly trained and licensed.
2. Plan the vent system so that Code required distances are maintained from plumbing and wiring.
3. Make certain the power supply is adequate for the fan motor requirements. Do not add the Power Venter to a circuit where the
total load is unknown.
4. The installer must verify that the BTU/hr. input of the appliance does not exceed the recommended input of the SS2G. See
Application Table on page 1 of these instructions for sizing information.
5. Flue gas temperatures must not exceed 650 degrees F at the Power Venter inlet. Ambient temperatures must not exceed 104
degrees F. Temperatures above this range can cause a fire resulting in property damage, personal injury or death.
6. “Safety inspection of a previously used gas appliance” as outlined below must be performed before installation of the SS2G as
outlined in ANSI Z223.1/NFPA #54, Appendix H.
7. The electrical load controlled through the Fan Proving Switch must not exceed the electrical ratings marked on the Fan Prover.
Improper installation, adjustment, alterations, service or maintenance can cause injury or property damage. Refer to this
manual. For assistance or additional information consult a qualified installer, service agency or the gas supplier.
*SAFETY INSPECTION OF A PREVIOUSLY USED GAS APPLIANCE
(Perform prior to SS2G installation)
The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in safe condition
for continuing use.
The following procedure is based on central furnace and boiler installations and it should be recognized that generalized procedures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to determine
safe operation of the equipment.
a. Perform this procedure prior to any attempt at modifications of the appliance or installation of the SS2G.
b. If it is determined there is a condition which could result in unsafe operation, shut off the appliance and advise the owner of the
unsafe condition.
Follow the steps below in making the safety inspection:
1. Conduct a gas leakage test of the appliance piping and control system downstream of the shutoff valve in the supply line to the
appliance.
2. Visually inspect the venting system and determine there is no blockage or restriction, leakage, corrosion and other deficiencies
which could cause an unsafe condition.
3. Shut off all gas to the appliance(s).
4. Inspect burners and crossovers for blockage and corrosion.
5. Applicable only to furnaces: Inspect heat exchanger for cracks, openings or excessive corrosion. Check both the limit control
and fan control for proper operation.
6. Applicable only to boilers: Inspect for evidence of water or combustion product leaks. Determine that the water pumps are in
operating condition. Test low water cutoffs, automatic feed controls, pressure and temperature limit controls and relief valves in
accordance with the manufacturer's recommendations to determine that they are in operating order.
