The lower vent opening can also be used as an access door to the gas valve & other components, if it meets the above size requirements. Lower vent opening/(s) can be installed at the sides of the enclosure (one on the left & one on the right), back or front. It is recommended to place one opening on all sides of longer units, to allow for better distribution across all fans of air taken in from the bottom.
