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.

REMINDER : The most significant preventer of wind-induced air infiltration is choosing a proper termination location of
the SideShot before installation, see requirements on page 6, under "Vent Hood Termination Clearances."

Verify that the Draft Adjustment is appropriate for the BTU/hr input, as shown on the "Draft Adjustment Chart," page 16. If neces-
sary, change setting by loosening both nuts on each side of the Vent Hood and center both indicators to the desired setting.
Tighten the four nuts to secure new draft adjustment.

Burner Adjustment: Verify that the over-fire draft matches that recommended by the heating equipment manufacturer. Adjust the
combustion efficiency and smoke characteristics to optimum levels of performance.

Combustion Air: Modern construction methods and materials have reduced natural air infiltration rates to extremely low levels.
Even older homes can lack adequate air for combustion, when insulation upgrades and other weatherization methods have been
installed. It is recommended that fuel burning appliances have dedicated sources of outside air for combustion. This may be sim-
ply accomplished by running a properly sized duct from outdoors and terminating it near the burner air intake. Accessory air
intakes are available that connect to the burner motor, using it to pull in the outdoor air. The Tjernlund IN-FORCER

TM

Combustion

Air Intake tempers the raw outdoor air as it is delivered to the burner. Without a source of outdoor air for combustion, a tight
home's negative pressures will draw odors back through the venting system during the appliance off cycle.

Chronic Oil Odor Conditions: Certain features of the specific appliance and installation, e.g. high heat-retention combustion
chamber; low-mass, dry-base; piping system design; oil impurities; air in lines, can all contribute to an increased production of oil
odor and cannot always be anticipated. For extreme cases of oil odor nuisance Tjernlund recommends the practice of post-purg-
ing the burner during the vent system post-purge. A burner post-purge cycle can eliminate any shortcomings of compatibility
between the specific installation and the SideShot. Burner post-purge kits, such as, Tjernlund's P/N 950-2043, are available from
most oil equipment distributors. Burner post-purge kits should be used on installations where the combustion air is being ade-
quately supplied, yet oil odors continue.

IMPORTANT
Any adjustment to the draft setting must be followed by an over-fire draft measurement and necessary adjustments to the
primary air intake on the burner and barometric draft control. See “Draft Adjustment Procedure”, pages 16, 17.
