Notes:

For servicing or cleaning, a 24" front clearance is recommended.
Unit connections (electrical, flue, and drain) may necessitate greater clearances than the minimum clearances listed above.
In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater.
Refer to the appropriate USA and Canadian codes: In the USA: the National Fuel Gas Code NFPA 54 / ANSI Z223.1. In Canada: the Canada National Standard of Canada, CAN/CSA B149.1 and CAN/CSA B142.2.
C = If placed on combustible floor, the floor MUST be wood ONLY.
