For installations where dirt, dust, and other airborne contamination is presenet in the indoor envirmonet, it is recommended to use seperated combustion units (Model UBZ). These models use air from outside the space for combustion. This will help reduce the build up of contaminates on the burner which would affect the combustion process. Refer to the installation manuals for recommended frequency of maintenace and cleaning.
