6. Perform a smoke test and make any adjustments to the burner air shutter, SS1C draft control on the vent hood or the
barometric draft control to arrive at a trace of smoke (between 0 and 1) at a minimum over fire draft of -.02” W.C..
7. Perform a CO 2 test at the same location as the smoke test. Reduce the CO 2 1% to 2% by opening the burner air shutter.
Recheck over fire draft and increase venter draft or adjust barometric damper closed (more draft) if necessary to maintain a
minimum of -.02” W.C..
Do not allow heating system to run at less than a -.02” W.C. over fire draft or at a CO 2 level that is less than a 1% reduction from
the value measured at a trace of smoke and a -.02” W.C. over fire draft. If these parameters are unobtainable, contact Tjernlund at
1-800-255-4208 for Technical Assistance.
8. Remove the call for heat from the heating system. NOTE: The SS1C will run in post-purge mode which is factory set at 2
minutes and adjustable up to 16 minutes. Allow the system to cool down to ambient room temperature.
9. Restart the heating system.
10. At 5 minutes into the restart, read and record the inlet temperature _______C. If this temperature is above 121
0 C (250 0 F),
continue to step 11. If this temperature is below 121 0 C (250 0 F), use an approved insulated pipe / vent connector. Verify that
the over fire draft and CO 2 have not changed, If they have, redo the adjustment steps. With insulated pipe / vent connector,
redo the 5 minute temperature test and record the new value here _______C. If insulated pipe / vent connector did not
increase the inlet temperature above 121
0 C (250 0 F) within 5 minutes of the heating system call for heat, call 800-255-4208
for technical support.
11. Lock down the burner primary air adjustment, the barometric adjustment knob and the SS1C draft adjustment with four lock
nuts on adjustment cone brackets, (See Diagram P). Verify over fire draft and CO 2 readings have not changed from earlier values.
DRAF
COMBUSTION AIR
Adequate combustion air is vital for proper combustion and for safe venting. Likewise, for proper SS1C performance, adequate
combustion air must be available to the appliance. Many installers assume adequate combustion air is present, especially in older
homes. In some cases this is a false assumption, because many older homes have been made "tight" due to weatherization. Size
the combustion air opening(s) into the appliance room as outlined in local or national codes. When installing a SS1C, it is not nec-
essary to supply any more combustion air than normally required when conventional venting. Common symptoms of inadequate
combustion air include: Fan Proving Switch short cycling, odor present at the end of burner cycle, outside air enters the structure
through the SS1C Vent System on SS1C/Appliance off cycle.
FINAL SYSTEM OPERATION CHECK-OUT
1. Adjust thermostat or appliance controls to call for heat.
2. Verify that the SS1C operates first, prior to burner ignition.
Allow heating equipment and SS1C to operate continuously while performing steps 3-5.
3. Close all doors and windows of the building. If heating equipment is installed in utility room or closet, close the entrance door to
this room. Close fireplace dampers.
4. Turn on all appliances in the structure that exhaust indoor air during their operation, e.g. turn on clothes dryer and exhaust fans
such as range hoods, bathroom exhaust and whole house fans.
5. Allow SS1C and equipment to operate for at least 15 minutes. Tripping of the burner circuit by the Fan Prover Switch or High
Limit during the 15 minute operation indicates an unsafe operating condition. Turn fuel supply off to appliance and DO NOT
OPERATE UNTIL UNSAFE VENTING CONDITION IS INVESTIGATED BY QUALIFIED SERVICE PERSONNEL.
6. Turn thermostat or equipment controls to the "off" position. Verify that the venter operates for the post-purge time period set
after the burner stops firing. See “Pre / Post-Purge Settings” on page 5.
7. Return all windows, doors and exhaust fans to their original conditions of use.
TROUBLESHOOTING OIL ODORS
Many problems can be eliminated quite easily by having the equipment properly set up by a professional oil-heat service contrac-
tor. The sophistication of today's heating equipment and instrumentation needed for efficient operation requires proper training.
There is no substitute for the work of a qualified oil-heat service professional. All trouble shooting recommendations that follow
assume the equipment is installed and maintained by a qualified service person.
Post-purge: A post-purge is always necessary on oil installations. The factory default post-purge time period is 2 minutes. Just
as a chimney continues to draft after the burner has shut-down, the SS1C will continue to run to clear the vent system of residual
gases. The duration of the post-purge cycle is adjustable from 0 to 16 minutes. We recommend a minimum of 2 minutes post-
purge on oil.
Draft Adjustment: The SideShot Draft Adjustment, located outdoors on the Vent Hood, has two functions: A) It allows the installer
to fine-tune the amount of draft that the SideShot must develop to vent the specific appliance, and B) It prevents air infiltration
caused by strong winds and gusts. Air infiltration back through the vent system will bring with it the odors from the flue gas residue
on the inside of the vent pipe. When the Draft Adjustment is at an inward setting (lower number) the Vent Hood will deflect a
greater volume of wind than at a higher setting.
