CONDENSATE DRAIN
This furnace is designed to remove both sensible and latent
heat from the combustion products. As a result water vapor
is condensed in the secondary heat exchanger. This
condensate must be drained either to the outdoors or, where
local code permits, to a sewage system.
In areas where floor level drains are not available a
condensate pump may be employed. This condensate
pump must be constructed of corrosion resistant materials.
It must also have an auxiliary switch that will shut down the
furnace in the event of a pump failure or drain tube
blockage.
IO-231
DO NOT run the condensate drain to an outdoor drain or to
an unheated area where the possibility of freezing may
occur.
Note: Some locals require the condensate to be
neutralized. Check local codes.
