• Flame height and appearance will vary depending
upon venng conguraon and the type of fuel used.
• Provide a means for visually checking the vent con-
necon to the appliance aer the replace is in-
stalled.
• A minimum of 1” (25mm) clearance on all sides of the
vercal vent pipe must be maintained. Ac insulaon
shields may be insulated using unfaced insulaon
products listed as noncombusble per ASTM E 136.
• A minimum of 1” (25mm) clearance on the top, sides,
and boom of the horizontal vent pipe must be main-
tained. Wall thimble products that comply with the
required clearances to combusbles must be installed
for all horizontal vent runs that pass through interior
or exterior walls. These wall thimble products may be
insulated using unfaced insulaon products listed as
noncombusble per ASTM E 136.
• The provided vent heat shield is required to be in-
stalled in all venng scenarios. See Figure 7.1, 7.2, and

7.3 Vent Restricon
• Burner ame appearance and characteriscs are aect-
ed by altude, fuel quality, venng conguraon, and
other factors. To achieve desirable ame appearance,
the vent exhaust may be restricted by the restrictor
plate (included in components packet).
• The restrictor plate is shipped with all inner rings intact,
and when installed, provides the most vent restricon.
There are (2) inner rings that can be knocked out. As
you knock out and remove an inner ring you have less
vent restricon where removing both inner rings you
will have the least amount of vent restricon.
• Follow FIGURE 7.4 for restrictor plate installaon before
aaching venng or through the bae if venng is al-
ready aached. For vent restricon plate recommenda-
ons and adjustments, see secon 12.3.3, Vent Re-
stricon (aer installaon).
