• If the water heater has been out of use for a long period of time, make sure that you fill the
condensate trap with water. This is to prevent dangerous exhaust gases from entering the building.
Failure to fill the condensate trap could result in severe personal injury or death.
* Do not use the condensate water, discharged from the drain pipe, for drinking purposes.
Filling the Condensate Trap with Water (Indoor Installation)
1) Fill the condensate container by pouring
approx. 10 oz.(280ml) of water into the
exhaust accessory on the top of the
appliance as illustrated below. Or, if the
vent pipe has already been installed:
2) After installing the drain pipe, make sure
that the area around the appliance is well
ventilated; open a window or a door if
necessary. Then, operate the unit and verify
that condensate is coming out of the drain
pipe. (During normal use of the water
heater, condensate will begin to discharge
from the drain pipe within 15 minutes of
use. However, depending on the season
and/or installation site conditions, it may
take longer.)
*Note: This procedure must be done on
each unit installed on the system.
