a Regulatory citations are listed in brackets.

b Monitor may be installed in the firebox or in the ductwork immediately downstream of the firebox before any substantial heat exchange is encountered.

c “Continuous records” is defined in § 63.111 of this subpart.

d NCS = Notification of Compliance Status described in § 63.152 of this subpart.
