4.15 Disposal of Condensate
High efficiency gas condensing Water Heaters create
condensation when operating. Condensation has
acidic (pH) of approximately 4-5.
Condensate must be drained in accordance with all
local regulations. Follow your local code with regards
to the disposal of condensation.
One of 4 disposal methods must be followed
1. to floor drain
2. to neutralizer drain (optional kit * )
3. to laundry tub
4. to condensate pump (field supplied)
If a neutralizer is installed, periodic replacement of the
lime stone (or neutralizing agent) will be required. The
rate of depletion of the lime stone varies upon usage
of the Water Heater.
During the first year of operation, please check the
neutralizer every few months for depletion.
Apply only corrosion-resistant materials for the
condensate drain lines such as 1/2˝ PVC, CPVC,
Polypropylene pipe or included plastic hose.
NOTICE
For Category II and IV water heaters, be installed so as
to prevent accumulation of condensate; and
For Category II and IV water heaters, where necessary,
have means provided for drainage of condensate.
AVIS
les chaudières de catégories II et IV doivent être
installées de façon à empêcher l'accumulation de
condensat; et
si nécessaire, les chaudières de catégories II et IV
doivent être pourvues de dispositifs d'évacuation du
condensat.
CAUTION
Condensate is mildly acidic (pH=5), and may harm
some floor drains and/or pipes, particularly those
that are metal. Ensure that the drain, drainpipe,
and anything that will come in contact with the
condensate can withstand the acidity, or neutralize
the condensate before disposal. Damage caused by
failure to install a neutralizer kit or to adequately
treat condensate will not be the manufacturer’s
responsibility.
