CAUTION
Flue condensate removal
(For Models LX-50 - LX-300 only).
Install a drip tee within the first 3' (1 m)
of flue venting for flue condensate
removal. Failure to follow these
instructions could reduce the service
and efficiency of the secondary heat
exchanger.
If flue vent is less than 10' (3 m) long
and a sidewall exit, then no drip tee
needed.
