Unites States see NFPA 31, for recommended servicing procedure. Clean flue pipes on a
regular basis. Check flue and combustion air pipes for any leak.
CHANGING NOZZLE
It is recommended that the nozzle be replaced once a year. If a new nozzle of a different size
is installed, change the blower speed according to section BURNER INSTALLATION
AND

• IMPORTANT SEE WARNING PAGE 7
CONDENSATE NEUTRALIZER
The media bag contained within the condensate treatment tank should be replaced once per
year or for every 600 USG (2300L) of oil used in the furnace or if the PH level at the outlet of
the treatment tank falls below 5.0 (whichever comes first). A replacement media bag can be
acquired from your local dealer.
The condensate from the furnace is slightly acidic with a pH of about 4; a neutral fluid would
have a pH of 7. If the condensate is not conditioned, damage could result in waste water
handling system which would result in expensive repairs.

During the first hours of operation. The appliance self-cleans its interior. The result
being that for the first 20 hours of activity, the condensate liquid will be brownish and
thereafter stabilize and become of normal ‘’water’’ color.

season or as required. Use new approved disposable filters of the same size and type. Dirty,
clogged or wrong sized filters will impair the furnace performance and may cause the furnace
