DESCRIPTION
The SS2G is a mechanical vent system designed and listed for use with natural draft gas heating equipment. It is factory assem-
bled 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 aHigh 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, insu-
lated vent connector to prevent problems related to condensation.

*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 proce-
dures 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.

Typical short vent pipe installation
ELECTRICAL WIRING
All wiring from the SS2G to the appliance must be appropriate Class 1 wiring as follows: installed in rigid metal conduit, intermediate
metal conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable, or be otherwise suitably
protected from physical damage. Note: We recommend the use of flexible conduit for connections to the SS2G to allow for slide
out servicing feature of venter assembly.
The electrical contact ratings for the diaphragm Fan Proving Switch and High Limit are as follows:
FAN PROVING SWITCH HIGH LIMIT
3 Amps (full load) at 24 VAC 10 Amps (full load) at 24 VAC
36 Amps (locked rotor) at 24 VAC 60 Amps (locked rotor) at 24 VAC
The Fan Proving Switch and High Limit are not suitable for loads which exceed the above limits.
1. The installer must ensure that all electrical connections between the appliance and Power Venter are tight and that all wires are
positioned and secured so they cannot come in contact with high temperature locations. Use adequate conduit supports where
necessary.
2. The installer must ensure that the internal appliance transformer is rated no lower than 40VA.
DIAGRAM I
INLET PIPE INSTALLATION
1. Remove 4” round inlet pipe from box.
2. Align the 4 slots of the inlet pipe to the 3 pins and
proving switch sensing tube, push pipe up until it
bottoms out in the SS2G inlet.
3. Turn the inlet collar clockwise to lock in place,
(See Diagram I). IMPORTANT: After vent pipe
is installed verify inlet pipe is locked tightly in place.
INSTALLATION OF VENT PIPE
The SS2G inlet is designed to accept 4” single wall or type “B” vent pipe. It will also accept 4” flexible vent connectors. The vent
pipe used must be in compliance with local codes and the listing of the vent pipe/connector manufacturer.
Always use a vent pipe/connector of the same diameter as the appliance flue outlet. Use a tapered reducer near the SS2G inlet
pipe if the appliance flue outlet is larger than 4”.
Determine vent pipe layout which will allow for the least amount of elbows to the appliance. Calculate the equivalent vent pipe
length from the appliance to the SS2G Vent System by adding the straight vent pipe length and the equivalent elbow lengths.
Each 90 degree elbow is equal to 10 feet of straight vent pipe, each 45 degree elbow is equal to 5 feet of straight pipe. The equiv-
alent vent pipe length must not exceed 50 feet from the appliance to the SS2G Vent System. Vent runs of over 15 linear feet
require the use of an approved, insulated vent connector to prevent problems related to condensation. It is not necessary to main-
tain a 1/4" rise per foot of horizontal when Side Wall Venting.
NOTE: Installing a vent pipe “jog” on vertical vent pipe layouts allows for easier dismantling when servicing is necessary,
(See Diagram J).

3. The installer must ensure that the heat anticipator in the comfort thermostat is adjusted according to the thermostat
manufacturer’s recommendation.
4. All wiring must be in compliance with local codes or in their absence, with the latest Edition of the National Electric Code (NFPA #70).
5. Disconnect 115V power before attempting to wire the Power Venter to the appliance. Power may be disconnected by means of
the appliance circuit breaker/fuse.
NOTES:
While it is impossible to include every possible wiring scenario, the following diagrams represent the most common. If wiring the
SS2G to an appliance not equipped with the controls shown on the following diagrams, determine which terminals of the gas
valve are considered “HOT” and “COMMON” and follow the steps on page 9.
When wiring Power Venter to the gas valve wire all thermostats, zones, circulators and limits as would normally be done if venting
into a chimney.NAT
T PROCEDURES
WIRING SS2G WITH SINGLE ZONE THERMOSTAT
SEQUENCE OF OPERATION WITH SINGLE ZONE THERMOSTAT:
Adjust the furnace thermostat to call for heat. The Power Venter should start. After a slight delay, the furnace burner should fire.
The delay is caused by the Power Venter fan proving switch. The delay will be no more than 4 seconds. If you are unable to
detect a slight delay, contact Tjernlund Products, Inc. at 1-800-255-4208 for assistance. When the fan proving switch closes, the
furnace combustion relay is energized. Normal combustion sequence for the furnace begins: induced draft furnace blower starts,
its proving switch makes energizing ignition control and/or gas valve. DO NOT OPERATE THE FURNACE WITHOUT THE FAN
PROVING SWITCH WIRED INTO THE 24V FURNACE CIRCUIT!
NOTE: When Power Venter is interlocked with a thermostat wire all zones, circulators and limits as would normally be done if
venting into a chimney.
If you are unable to wire the SS2G as outlined in these instructions, call Tjernlund’s Customer Service Department toll free at
1-800-255-4208 for assistance.

WIRING SS2G WITH THERMOSTAT
SS2G WIRED TO 24V GAS VALVE
SS2 SEQUENCE OF OPERATION WIRED TO GAS VALVE:
As the thermostat/aquastat senses a need for heat, the internal switch of the thermostat/aquastat will close. The Switch closure
completes the 24V electrical circuit to the internal controls of the appliance. Before the 24V signal reaches the appliance gas
valve, it is interrupted by the Power Venter Relay/Timer and Fan Proving Switch. When the Power Venter Relay/Timer receives
the 24V signal, the contact side closes completing the 115V circuit to the Power Venter motor. The air movement generated by
the Power Venter closes the Fan Proving Switch and completes the circuit to the appliance gas valve. The appliance gas valve
will only receive power when the appliance thermostat/aquastat is calling for heat and the Power Venter is operating. When the
appliance thermostat/aquastat is satisfied, 24V will be discontinued to the Relay/Timer and the Power Venter will continue to oper-
ate for a nonadjustable post purge period of approximately 45 seconds.
