Burner test results
The indicated values for manifold and
air gate settings are the result of
production line testing under ideal
conditions.
Final burner adjustment to suit local
field conditions is necessary for safe
operation.
Observe the stated minimum and
maximum supply gas pressures.
Exposing the burner gas train to supply
pressures other than the stated values
can cause unsafe conditions.
Viessmann strongly recommends the
installation of an approved type CO
detector in the vicinity of any gas
burning equipment. Observe national
and/or local code requirements. If in
doubt consult your local LP company.
Verification of results
The burner adjustment values indicated
serve as a starting point only.
Combustion results must be field
verified using properly calibrated
Bacharach or equivalent instruments.
Each burner is certified for one input
only. Do
not
overfire or underfire
burner.
