Tjernlund SS2 SideShot (Discontinued Version - Pre UC1 Universal Control) 8504063 Rev B 11/99 - Manual (Page 10)

ELECTRICAL WIRING OIL
All wiring from the SS2 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 SS2 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
6.2 Amps (full load) at 120 VAC 10 Amps (full load) at 120 VAC
36 Amps (locked rotor) at 120 VAC 60 Amps (locked rotor) at 120 VAC
The Fan Proving Switch and High Limit are not suitable for loads which exceed the above limits.
SEQUENCE OF OPERATION WITH SS2 INSTALLED ON OIL FIRED APPLIANCES:
Control signal from thermostat, aquastat or primary control is intercepted and routed to terminal “O” on SideShot terminal strip.
When terminal “O” is energized with either 24 VAC or 120 VAC, the SS2 Relay/Timer receives current and SS2 motor and cooling
fan are energized. After draft is established within the SS2, the Fan Proving Switch closes within 5 to 10 seconds energizing ter-
minal “Y”, which completes the circuit allowing burner to fire.
The "O" input terminal on the SideShot can accept either a 24 VAC or 120 VAC control signal. For most furnace applications
it may be easier to interlock with the 24 VAC thermostat circuit. For most boiler applications it may be easiest to interlock with the
120 VAC primary control circuit to the burner motor. For boiler applications with solid state primary controls it is recommended that
the interlock be made between the aquastat and the primary control to avoid the need for a field installed isolation relay. This relay
is necessary to eliminate false triggering of the SideShot by circuit checks that are common with solid state controls. Choose the
interlock method that best fits your application.
