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 SS1 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 17 . 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

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.

TROUBLESHOOTING ELECTRICAL PROBLEMS

The following guide is intended to be used if a problem occurs during the use of the SS1 side wall vent system. It may be
necessary to measure voltage during troubleshooting. Extreme caution must be exercised to prevent injury. If you are
unable to determine the defective part with the use of this guide, call your Tjernlund distributor or Tjernlund Products direct
at 1-800-255-4208 for further assistance.

LED STATUS & FAULT INDICATORS

LED INDICATOR LIGHTS
LED #1 (Amber) Appliance call for heat.
LED #2 (Green) Safety circuit through P1 & P2 (SS1 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 SS1 motor 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)

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”, page 17.
