GENERAL INFORMATION
GAS
Proper gas size is imperative, as this unit may be able
to get sufficient gas but other appliances on the same
gas line will not. This could cause issues throughout
the home.
CONDENSATION
Remove the cap to prevent an A022 error code. Con-
nect a ½” drain hose at the condensation drain (Green
connection in following illustration.) The yellow con-
nection in the illustration is used to drain condensation
from a neutralizer. (Most users will not need this con-
nection.)
