GENERAL INFORMATION
GAS
Proper gas size is imperative, as this unit may be able to
get sufcient gas but other appliances on the same gas
line may not. Alternatively, other appliances may cause
insufcient gas to the unit if the gas line is undersized.
Refer to U&C Manual for gas supply requirements.
CONDENSATION
Remove the cap to prevent an A029 error code. Connect
a ½” ID drain hose at the condensation drain (Shown in
yellow in following illustration.)
