This Gas Fireplace has been approved for,
•
Vertical installations up to 40 feet (12m) in height.
Up to a 10 ft. horizontal vent run can be installed
within the vent system using a maximum of two 90
o
elbows. (Fig. 23)
•
Up to two 45
o
elbows may be used within the hori-
zontal run. For each 45
o
elbow used on the horizon-
tal level the maximum horizontal length must be
reduced by 18".
Do Not Back Fill Around Snorkel. Soil
Should Not Be Less Than 4" Below

necessary to extend the vent pipes out as far as the
protruding wall face. (Fig. 22)
