Maintenance is to be performed at least once a year only by a qualified contractor recognized
by the authority having jurisdiction. Maintenance performed by any other party will void the
warranty.
The following maintenance routines are specific to the Paradigm furnace and must be
performed in conjunction with all other maintenance routines listed in Clauses 14.2 to 14.5 of
the CSA B139, Installation Code for Oil-Burning Equipment.
Burner
Refer to section 5.0 BURNER SPECIFICATION of the Manual.
o Verify that the fuel pump pressure is set to the correct pressure and adjust as required.
o Check for after drip and sharp fuel cutoff and replace automatic cut-off valve if necessary.
o Check and inspect electrodes and porcelain holders and clean or replace if necessary.
o Replace nozzle with a new one of the exact type listed for the output requirements.
o Clean turbulator and nozzle assembly, verify that the turbulator setting matches the
nozzle being used and adjust as required.
Furnace
o Inspect chamber and replace if necessary.
o Clean furnace as described in section 6.0 CLEANING INSTRUCTIONS.
o Replace air filter with the same size and type.
o Replace the condensate conditioner.
o Initiate a call for heat and observe through the sight glass that there is flame.
o After five minutes of burner operation (steady state) measure the smoke density and
adjust the burner air setting as required to obtain a zero to trace reading.
o Measure the CO
2
and adjust the air setting slightly to obtain between 11.5 and 12 %.
o If, while monitoring the CO
2
on start up, you witness changes in the % reading while the
blower ramps up, this may indicate a heat exchanger or gasket leak. Further testing may
be required to verify this.
o Measure the flue gas temperature through the hole in the vent pipe and verify that it is in
the range between 90 to 120°F.
o Disconnect the black wire from the C2 terminal of the low voltage section of the printed
circuit board. Initiate a call for heat and ensure that the limit shuts the burner off.
Reconnect the black wire initiate a call for heat and verify that the burner and furnace
