VENT TERMINATION CLEARANCES
These instructions should be used as a guideline and do not supersede local codes in any way.
Install venting according to local codes, these instructions, and the current (USA) National Fuel
Gas Code ANSI-Z223.1 / NFPA 54, or (Canada) CAN/CGA-B149.1 standards.
Horizontal Vent Termination Clearances
The horizontal vent termination must have a minimum of 3" (77 mm) clearance to any overhead
combustible projection of 2-1/2" (64 mm) or less (see
Figure 3
)
.
For projections exceeding 2-1/2"
(64 mm), see
Figure 3
. For additional vent location restrictions refer to
Figure 4 on Page 9
.
LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important.
Due to high temperatures, the appliance
should be located out of traffic and away from
furniture and draperies (Figure 2).
En raison des températures élevées,
l’appareil devrait être installé dans un
endroit où il y a peu de circulation et loin
du mobilier et des tentures (Figure 2).
The location should also be free of electrical,
plumbing or other heating/air conditioning
ducting.
Be aware that this is a heat producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
Do not insulate the space between the appli-
ance and the area above it
.
The appliance must be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be lo-
cated on or near conventional construction
materials. However, if installed on combustible
materials, such as carpeting, vinyl tile, or other
combustible material other than wood flooring,
the appliance shall be installed on a metal or
wood panel extending the full width and depth
of the appliance.
