DESCRIPTION

The SS1 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 SS1 automatically vents the flue gases from heating equipment to the outdoors. By combining outside air with high-tech insulation, surrounding combustible materials and the Vent Hood exterior remain at safe temperatures. After each burner cycle the SS1 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 SS1 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 SS1’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 proper category listed below. All BTU/hr. capacity ranges are 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 should use an approved, insulated vent connector to prevent problems related to sulfur condensation.

2.Disconnect power supply from the SS1 and heating equipment when making wiring connections and servicing the SS1. 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.The SideShot motor shaft must be mounted horizontally to ensure proper operation of the Fan Proving Switch and prevent motor bearing wear.

5.Flue gas temperatures must not exceed 650oF at SideShot inlet. Ambient temperature must not exceed 104oF.

6.Oil fuel, flue gas temperature at vent system inlet must be at least 250oF during appliance steady state.

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

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

*SAFETY INSPECTION OF A PREVIOUSLY USED APPLIANCE

(Perform prior to SideShot 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 SS1.

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

 

 

in the supply line to the appliance.

Inspect burners and cross overs for blockage and corrosion.

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.

*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 SS1 High Limit. If Limit was tripped and SS1 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 newtrippedfaultandwillSS1replacefires,anyi vestigatepreviouscausefault. 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 indicated 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 SS1 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.
