Vertical Vent Installation
Important Notes
1. All vertically terminated vent installations use 6-5/8”x 4”
Security™ Secure Vent™ pipe*.
2. If the vent passes through a ceiling or floor, a firestop
- Simpson #963 or Security™ #SV4BF - is required.
3. If the vent passes through the roof, a roof flashing - Simp-
son #943 or 943S or Security™ #SV4FA or SV4FB - and
storm collar - Simpson #953 or Security™ #SV4FC - are
required.
4. A 1-inch clearance from the vent pipe to combustible
materials must be maintained.
5. A maximum of either two 45º elbows or two 90º elbows
may be used. See Page 16 for allowable offsets.
6. The maximum system height is 30 feet (9.1M) and the
minimum is 10 feet (3M).
Flue Restrictors
This stove requires a balanced flue to ensure proper com-
bustion. As such, flue restrictors may need to be installed
depending on the vent configuration of your stove. The
drawings on the next page show all the allowable pipe con-
figurations for the Epic™ gas stove. To properly install the
flue restrictors, find your pipe configuration in the drawings
on the next page and note which restrictor setting is recom-
mended. The flue restrictors are shipped in the firebox of
your stove. Install the flue restrictors using the four allen
head screws according to the diagram below. Install the
flue restrictor screws in their original holes in the top of
the firebox. Restrictor positions are based on tests run in
a laboratory.
