DESCRIPTION

The SS2 is a mechanical vent system designed and listed for use with natural draft oil or gas heating equipment. It is factory assembled and wired.
The SS2 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 SS2 will continue to operate in post-purge mode to purge the heater and
vent of residual flue gases. A factory post-purge time is set at 2 minutes and is adjustable up 16 minutes, see “Pre / Post-purge Settings” on page 5.
The SS2 features a safety system consisting of the integral UC1 Universal Control, a Fan Proving Switch and a High Limit temperature control. These
devices monitor the SS2’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) fall within the inputs listed below. The BTU/hr. capacity range is based on a maximum of
50 equivalent feet (15 meters). To determine equivalent feet, add the total length of straight vent pipe plus 10 feet (3 meters) for each 90 degree elbow
and 5 feet (1.5 meters) for each 45 degree elbow. Vent runs of over 15 linear feet (4.5 meters) require the use of an approved, insulated vent connector
to prevent problems related to condensation.

The SS2 Vent System may only be used on Flame Retention Head Oil Burners for oil installations.

5. The SS2 shall not be installed where flue gas temperatures exceed 650oF (343oC) at its inlet. Flue gas temperature verification:

A) On oil fuel, verify flue gas temperature at appliance inlet is at or above 250oF (121oC) after 5 minutes of operation during setup. See “Oil Draft
Adjustment Procedure” on page 16, step 9.

AND

B) After 15 minutes of operation, measure flue gas temperature to verify it is not more than 650oF (343oC) at SS2 inlet.

6. Vent runs of over 15 linear feet (4.5 meters) 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 SS2. 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.

If oil nozzle is changed or other equipment is added perform “Draft Adjustment Procedure” on pages 15, 16 again.

CAUTIONS

The SS2 must be installed by a qualified installer (an individual properly licensed and/or trained) in accordance with all local codes or, in their
absence, in accordance with the appropriate National Fire Protection Association #31, #54, #211 and the National Electrical Code. In the absence
of local codes in Canada, installations must comply with CSA Std 139 (The National Building Code of Canada) and CSA Std 22.1 (The Canadian
Electrical Code).

Failure to install, maintain and/or operate the SS2 in accordance with manufacturer's instructions may result in conditions
which can produce bodily injury and property damage.

1. The installer must verify that the BTU/hr. input of the appliance does not exceed the recommended input of the SS2. See
“Application Table” on page 1 of these instructions for maximum input capacities.

2. Disconnect power supply from the SS2 and heating equipment when making wiring connections and servicing the SS2.
Failure to do so may result in personal injury and/or equipment damage. LED #5 (RED) should be off with power removed.

3. Plan the vent layout so that the code required clearances are maintained from plumbing, wiring and combustible materials.

4. Flue gas temperatures must not exceed 650oF (343oC) at SS2 inlet. Ambient temperature must not exceed 104oF (40oC).

5. Oil fuel flue gas temperature at vent system inlet must be at least 250oF (121oC) during appliance steady state.

6. Make certain power source is adequate for the SS2 requirements. Do not add the SS2 to a circuit when the total electrical load is unknown.

7. "Safety Inspection of a Previously Used Appliance", below must be completed when replacing a conventional chimney venting system
or when SS2 is installed on used heating equipment.

SAFETY INSPECTION OF A PREVIOUSLY USED APPLIANCE

(Perform prior to SS2 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. This 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. This procedure should be performed prior to any attempt at modifications of the appliance or installation of the SS2.
b. If it is determined there is a condition which could result in an unsafe operation, the appliance should be shut off and the owner

advised of the unsafe condition.

The following steps should be followed in making the safety inspection:

1. Visually inspect the venting system and determine there is no blockage or restriction, leakage, corrosion or other deficiencies
which could cause an unsafe condition.

2a. Oil Installations: Inspect burner and primary control for proper operation.
2b. Gas Installations: Conduct a gas leakage test of the appliance piping and control system downstream of the shutoff valve

3. Applicable only to furnaces: Inspect heat exchanger for cracks, openings or excessive corrosion. Check both the limit control and fan control
for proper operation.

4. 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.

LED STATUS & FAULT INDICATORS

LED INDICATOR LIGHTS

LED #1 (Amber) Appliance call for heat.
LED #2 (Green) Safety circuit through P1 & P2 (SS2 Limit & Fan Prover) is verified “Open” upon start-up. Indicates Venter

prover is closed during run cycle. Burner circuit is energized with contact closure from terminal 3 to 4.
LED #3 (Green) Power switched to SS2 motor & Cooling Fan from L to MTR & M.
LED #4 (Red) Status / Fault indicator.
LED #5 (Red) 115 VAC power supplied to board. Also used as a status indicator.

LED STATUS INDICATORS

LED #4 & #5 (Red) Flashing Alternately = Venter in Pre-purge. (Pre-Purge options 0, 5, 20, 35 seconds)
LED #4 & #5 (Red) Flashing in Unison = Venter in Post-Purge. (Post-Purge options 0, 30 seconds or 1, 2, 4, 8, 16 minutes)
LED #4 Flashing Continuously* = Fan Prover opened for more than 10 seconds during burner cycle.

(Venter will run for 10 minutes, attempting to make Fan Prover)

LED FAULT INDICATORS

Fault conditions are indicated by counting the number of times LED #4 (Red) flashes.

V

LED #4 Flashes 2 Times

Fan Prover was in electrically closed position prior to venter operation.

LED #4 Flashes 3 Times* Fan Prover does not close within 60 seconds after call for heat.
LED #4 Flashes 4 Times* Fan Prover did not re-close after 10 minutes of Venter operation.
LED #4 Flashes 5 Times* Fan Prover opened for more than 10 seconds during burner cycle but closed within 10 minutes.

* Investigate causes of Fan Prover not making, i.e; Firing burner at capacities or temperatures exceeding Venter limits, excessive vent pipe runs, high

winds, plugged / kinked Fan Prover sensing tube or a faulty Fan Prover. Reset SS2 High Limit. If Limit was tripped and SS2 fires, investigate cause
of high heat.

IMPORTANT: Fault codes will automatically be displayed after a fault condition occurs. If the call for heat interlock signal or 115
VAC power is removed, the UC1 board will reset and the fault will be stored in memory instead of displayed. Any new fault will
replace any previous fault.

tripped and SS2 fires, investigate cause of high heat.

CHECKING MEMORY FOR LAST FAULT CODE
IMPORTANT: Prior to accessing the fault code memory, note the settings of the dip switches so that they can be returned to their original Pre / Post-

Purge positions. When power is supplied to the UC1 use caution when moving dip switches.
The last fault code can be retrieved at any time by setting all dip switches 1-8 to the up, or “on” position. The last fault code, or lack there of, will be indi-

cated by counting the number of times LED #4 flashes. By moving any of the dip switches back to their original position, the fault code will be cleared.
NOTE: The UC1 board must have its 115 VAC power supply present when any of the (1-8) dip switches are moved back to their original position for the
fault code to clear.

PRE / POST PURGE AND PROVER STATUS CHECK DIP SWITCH SETTINGS

Remove power to SS2 and heating equipment when installing, servicing or changing dip switch settings. Failure to do so may result in
personal injury and/or equipment damage. LED #5 (RED) should not be on if 115 VAC supply power is removed from the control.

Pre-purge

Used for longer vent runs to get draft fully established throughout the vent system prior to burner ignition. Also beneficial for negative pressure prone
environments. IMPORTANT: Nuisance equipment lockouts may occur if our pre-purge is running in conjunction with and is longer than any equipment
timing circuit. Pre-purge settings must be shorter than burner control lockout time unless wired prior to burner control timing circuit (i.e. aquastat / ther­mostat).

Post-purge

A Venter post-purge has been factory set at 2 minutes. Confirm that dip switch #5 is in the up or "on" position. Oil fired equipment requires that the
post-purge be long enough to eliminate post cycle nozzle drip odor. A longer post-purge may be necessary for longer vent runs or high heat retention,
refractory lined combustion chambers. A shorter post-purge may be desired for gas installations.
