Ensure sidewall venting clearances are observed.
If installing a snorkel a minimum 24" vertical rise is necessary. The maximum horizontal run with the 24" vertical pipe is 36" (915mm). This measurement is taken from the collar of the fireplace to the face of the exterior wall. See vent graph for extended horizontal

If the foundation is recessed, use recess brackets (not supplied) for securing lower portion of the snorkel. Fasten brackets to wall first and then secure to snorkel with self drilling #8 x 1/2 sheet metal screws. It will be necessary to extend the vent pipes out as far as the protruding wall face (Fig. 22).

This Gas Fireplace has been approved for,
a)Vertical installations up to 40 feet (12 metres) in height. Up to a 10 ft. horizontal vent run can be installed within the vent system using a maximum of two 90o elbows. (Fig. 24)
b)Up to two 45o elbows may be used within the horizontal run. For each 45o elbow used on the horizontal level the maximum horizontal length must be reduced by 18 inches.
