Fluing Requirements for internal Models (cont)
Draining the Condensate
A flue condensate trap is fitted to the water heater so that acidic flue gas condensate does
not enter into the water heater flue-ways which may cause premature failure of the water
heater.
A drain line must be connected to the spigot on the condensate trap. The drain line is to
incorporate a trap and filled with water prior to the operation of the water heater. The drain
line from the trap to the point of discharge should be as short as possible, have a
continuously downward fall all the way from the water heater to the discharge outlet and
have no tap, valves or other restrictions in the pipe work. The drain line must be extended
to a discharge point where the condensate will not cause injury, damage or nuisance.
