Direct vent gas fireplace

[allseason]

What is the correct height above grade at the exterior for the vent on a direct vent gas fireplace, am I correct at 12"?

[Mike Lamb]

Correct.

NFPA 12.9.3 The vent terminal of a direct-vent appliance with an input of

10,000 Btu/hr (3 kW) or less shall be located at least 6 in. (150 mm)

from any air opening into a building, and such an appliance with an

input over 10,000 Btu/hr (3 kW) but not over 50,000 Btu/hr (14.7

kW) shall be installed with a 9 in. (230 mm) vent termination clearance,

and an appliance with an input over 50,000 Btu/hr (14.7 kW)

shall be at least a 12 in. (300 mm) vent termination clearance. The

bottom of the vent terminal and the air intake shall be located at

least 12 in. (300 mm) above finished grade. [ROP 54/Z223.1-2]
