eight (8) feet above grade directly in line with the exhaust vent

terminal for the horizontally vented gas fueled heating appliance 

or equipment. The sign shall read, in print size no less than one-

half (1/2) inch in size,

The state or local gas inspector of the side wall horizontally 

vented gas fueled equipment shall not approve the installation 

unless, upon inspection, the inspector observes carbon monoxide 

detectors and signage installed in accordance with the provisions 

of 248 CMR 5.08(2)(a) 1 through 4.

The following equipment is exempt from 248 CMR 5.08(2)(a)1
