The sign shall read, in print size no less than one-half (1/2) in. in size,

“GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS”.

•Detailed instructions for the installation of the venting system design or the venting system components; and

•A complete parts list for the venting system design or venting system.

Gas Equipment Venting System NOT Provided

•The referenced “special venting system” instructions shall be included with the appliance or equipment installation instructions; and

•The “special venting systems” shall be Product Approved by the Board, and the instructions for that system shall include a parts list and detailed installation instructions.
