Boiler Startup and Combustion Analysis
Before placing the boiler into service the combustion must be prop-
erly adjusted. Setting the combustion requires a combustion ana-
lyzer in working order that has been calibrated. A digital manometer
should also be available for testing incoming gas pressure. Once
the boiler has had the combustion set, a test report should be gen-
erated and left with the boiler as proof of correct startup and for ref-
erence for future maintenance. An explanation of complete
combustion analysis and start up procedures can be found in the
installation and maintenance manual supplied with the boiler.

Slant/Fin VSL II Quick Start Guide
The combustion analysis must be done by a qualified technician.
Ensure there is a sufficient way to emit the heat generated by the boiler
to allow for combustion testing, this can be accomplished by creating a
call for heat in all the zones or if using an indirect tank by running the
DHW at a faucet.
1. Enter the installers menu.
2. Scroll to parameter 2010 and set to High. Boiler will run for 20
minutes on High Fire.
3. Wait for the boiler to stabilize this may take a few minutes.
4. Insert the combustion analyzers probe into the test port
on the exhaust vent.
5. Wait till the readings stabilize and then check there range against
the table below.
6. If the combustion must be adjusted use a 2.5mm Allen wrench to
turn screw E on the gas valve. Turning the screw clockwise will
reduce the CO2 reading, while turning the adjustment screw
counter clockwise will increase the C02 level. Turn the screw in
quarter turn increments waiting for the readings to stabilize
between each turn.
7. Once the reading on high fire matches the desired level change
parameter 2010 to Low. Boiler will run for 20 minutes on Low Fire.
8. Ensure that the reading at low fire match the range in the table
given below, if they fall outside the given range contact technical
support.
9. Set parameter 2010 to Off, close and seal the combustion probe
port. The commissioning of the boiler is now complete.
