Through wall direct vent clearance to deck.

Recommended Posts

Look inside the fireplace for the rating plate. If you cannot find a rating plate noting the mfr., model and serial number then treat it as an unlisted appliance which must be removed. Otherwise, defer to a qualified hearth pro. The stated clearances vary by unit to unit and not just mfr. to mfr. so you can NEVER assume or try to apply general measurements. One may be shorter and another may be longer--you have to read the listed installation instructions-period.

I can tell you that functionally, if direct vent terminations don't have sufficient free circulation of air, they often operate sporadically. I've investigated many units that met the listed instructions for clearances but due to local effect of air currents and eddies, the thing just didn't run right or suffered outages, sooting, etc.
