Fireplace Vent and Patio Cover Framing Clearance?

[Richard W. Washington]

Ok. I'm sure there has to be a clearance requirement for this side wall fireplace vent considering they say 'H.O.T. in big letters across the front.

[Brian E. Kelly]

Is it touching Richard? The manufactures installation instructions would have the clearances. I think the mini mun I have seen is 2".

Call it out.

[Douglas Cossar]

Richard:

These vents are zero clearance, to the best of my knowledge. However I might suggest to the client that they monitor the situation to see if any scorching occurs while the fireplace is operating.


Cheers

[Richard W. Washington]

Just to be on the same side I'm going to take both of your suggestions and tell them it needs a 2" clearance and to monitor the framing for scorching. Thanks.

Fireplace vent, labeled "HOT", is touching patio cover wood framing. Verify manufacturer's installation clearance instructions and maintain as needed to prevent fire hazard.

[Ed Figueroa]

I agree with Larry. I have a zero clearance in my house. It gets so hot when I use the fireplace. Be safe than sorry.

combustibles of 2" at the vent pipe top

must be maintained for the first 12" of venting. The firestop
spacer

W010-0612 supplied with the unit must be used to
maintain this clearance. Thereafter a 1" clearance to
combustibles may be maintained using the firestop spacer

W500-0096

for use with flexible venting or firestop spacer

W500-0136

for use with rigid venting.

For safe and proper operation of the fireplace follow
the venting instruction exactly.
Deviation from the minimum or the maximum vertical
vent length can create difficulty in burner start-up and/
or carboning.
A terminal shall not terminate directly above a sidewalk
or paved driveway which is located betweeen two single
family dwellings and serves both dwellings. Local
codes or regulations may require different clearances.
In order to avoid the possibility of exposed insulation
or vapour barrier coming in contact with the fireplace
body, it is recommended that the walls of the fireplace
enclosure be “finished” (ie: drywall/sheetrock), as you
would finish any other outside wall of a home. This will
ensure that clearance to combustibles is maintained
within the cavity.

Wolf Steel, Simpson Dura-Vent,

Selkirk Direct Temp and

American Metal Amerivent venting systems must not
be combined.

Purge all gas lines with the glass door of the fireplace
open. Assure that a continuous gas flow is at the burner
before closing the door.
Under extreme vent configurations, allow several minutes
(5-15) for the flame to stabilize after ignition.
Six (6") inches is the minimum bend radius allowed for
the 7" diameter flexible liner.
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot
when using

Simpson Dura-Vent or Wolf Steel rigid
vent components and a minimum 1 inch rise per foot
when using Wolf Steel flexible vent components

FOR SPECIFIC VENTING PARAMETERS, REFER TO
PAGES 9-14.

GD33 & BGD33: When venting either a GD33 or a
BGD33, the horizontal run must be kept to a maximum
of 24 inches. A GD33 must be kept to a minimum of 12
inches and a BGD33 must be kept to a minimum of 8
inches. When terminating vertically, the vertical rise is
a minimum 36 inches to a maximum 40 feet from the
centre of the fireplace flue outlet. The maximum horizontal
run, when terminating vertically, is 7 feet.
