Table 2: Direct Vent Configuration
Components
i. Direct communication with outdoors.
Minimum free area of 1 square inch per
4,000 BTU per hour input of all equipment in
space.
ii. Vertical ducts. Minimum free area of 1
square inch per 4,000 BTU per hour input
of all equipment in space. Duct cross-
sectional area shall be same as opening
free area.
iii. Horizontal ducts. Minimum free area of 1
square inch per 2,000 BTU per hour input
of all equipment in space. Duct cross-
sectional area shall be same as opening
free area.
Alternate method for boiler located within
confined space. Use indoor air if two
permanent openings communicate directly
with additional space(s) of sufficient volume
such that be combined volume of all spaces
meet criteria for unconfined space. Size
each opening for minimum free area of 1
square inch per 1,000 BTU per hour input of
all equipment in spaces, but not less than
100 square inches.
6. Louvers and Grilles of Ventilation Ducts
a. All outside openings should be screened
and louvered. Screens used should not be
smaller than 1/4 inch mesh. Louvers will
prevent the entrance of rain and snow.
b. Free area requirements need to consider the
blocking effect of louvers, grilles, or screens
protecting the openings. If the free area of
the louver or grille is not known, assume
wood louvers have 20-25 percent free area
and metal louvers and grilles have 60-75
percent free area.
c. Louvers and grilles must be fixed in the
open position, or interlocked with the
equipment to open automatically during
equipment operation.
D. DIRECT VENT CONFIGURATIONS requires:
1. Beckett NX Burner
2. Direct Vent Conversion Kit
3. Double Wall Flex Oil Vent Pipe(FOVP).
Horizontal ducts. Minimum free area of 1
square inch per 2,000 BTU per hour input of all
equipment in space. Duct cross-sectional area
shall be same as opening free area.
Alternate method for boiler located within
