Vertical Through-the-Roof Application
This gas fireplace has been approved for:
•Vertical installations up to 40’ (12 m) in height. Up to a 10’ (3 m) horizontal vent run can be installed within the vent system using a maximum of two 90° elbows. (Fig. 23)
•Up to two 45° elbows may be used within the hori- zontal run. For each 45° elbow used on the horizon- tal plane, the maximum horizontal length must be reduced by 18” (450 mm).
Example: Maximum horizontal length:
No elbows | = | 10’ (3 m) |
1 x 45° elbow | = | 8.5’ (2.6 m) |

2 x 45° elbows = 7’ (2.1 m) |
• A minimum of an 8’ (2.5m) vertical rise is required. |
• Two sets of 45° elbow offsets may be used within the |
vertical sections. From 0 to a maximum of 8’ (2.5 m) |
of vent pipe can be used between elbows. (Fig. 24) |
• 7DVCS supports offsets. (Fig. 25) This application |
will require that you first determine the roof pitch |
and use the appropriate starter kit. (Refer to Venting |
Components List) |
• The maximum angular variation allowed in the sys- |
tem is 270°. (Fig. 24) |

Do not backfill around snorkel.
A clearance of at lest 4” must be main- tained between the snorkel and the soil.
If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fas- ten brackets to wall first, then secure to snorkel with self drilling #8 x 1/2 sheet metal screws. It will be necessary to extend vent pipes out as far as the protruding wall face. (Fig. 22)
