Adams Condensing Oil-Fired Furnace - Manual (Page 18)

When the furnace is used in connection with
a cooling unit, the furnace should be
installed in parallel with or on the upstream
side of the cooling unit to avoid
condensation in the heating element. With
a parallel flow arrangement, the dampers or
other means used to control the flow of air
must be adequate to prevent chilled air from
entering the furnace and, if manually
operated, must be equipped with means to
prevent operation of either unit unless the
damper is in the full heat or coot position.
FILTERS - READ THIS SECTION BEFORE
INSTALLING THE RETURN AIR
DUCTWORK
A FILTER MUST BE USED WITH THIS
FURNACE. Discuss filter maintenance with
the building owner. Filters are shipped with
this furnace. Filters must comply with UL900
or CAN/ULCS111 standards.
If the furnace is installed without filters, the
warranty will be voided.
Inspect Fitter Frequently!
Replace 3 times each heating season.
XI. START-UP PROCEDURE &
ADJUSTMENT
Please read the procedures outlined below
and familiarize yourself with the appliance
sequence of operation before conducting
any tests or starting the appliance.
Note; A separate start-up form is attached
to the instailation instructions and must be
completed and returned to the
manufacturer for warranty registration
within 30 days of installation.
Check that furnace is instaiied level. This is
important since the secondary heat
exchanger is pitched at 3 degrees for proper
condensate drainage. Check with a
carpenters ievel and shim accordingly.
Verify that the fuel supply lines are leak-
free. Inspect ait connections for air leaks.
Fuel system integrity is often assumed, but
cannot be overlooked. Test the fuel system
for integrity. Even a small leak can cause a
multitude of burner issues. Never use
compression fittings.
Verify pump pressure with appropriate test
instrument. (140 PSI) for Adams
INTERburner Mark 10 or Beckett NX.
Check pump seal by shutting off pump and
noting the pressure drop. The pump
pressure should drop approximately 20%
and hold indefinitely.
Prime oil filter supplied with the appliance
before bleeding air from system. Purge the
oil pump of air in the system as soon as the
burner motor starts rotating by or>ening
bleeder valve on pump and catch oil in
suitable container.
Check post-purge timing on primary safety
controi by examining dip-switch
configuration on the primary control. This
controi is factory set at 8 minutes post purge
time.
Locate fan control in blower compartment.
Check blower-on time delay. Set delay for
30 seconds.
Verify blower-off delay setting at 390-600
seconds. This is required for proper heat
removal from the heat exchanger once the
thermostat is satisfied.
Do not remove blower deck support bracket
located in the blower compartment. This
bracket may be confused for a shipping
bracket and must not be removed. This
bracket is installed in up-flow and counter­
flow models only. !t is a sheet metal
support bracket in the blower compartment.
Prime condensate drain trap with water.
Operate the burner for (3) minutes on, (3)
minutes off twice. Operate the burner for
approximately 30-40 minutes to cure the
internal ceramic fiber combustion
chamber. Be aware of moderate
odor/smoke upon initial firing and gradually
diminishing to nomnal over the break-in
period. Note the air handler should be
operating at all times during the break-in
period and final tuning.
You are now ready for the final fine-tuning.
The burner air settings are approximate
and needs to be adjusted to the vent system
in the fteld for most efficient operation.
