VENTING
WARNING
This fireplace must be vented to the outside. The venting system must NEVER be attached to a
chimney serving a separate solid fuel burning appliance. Each gas appliance must use a separate vent
system. Do not use common vent systems.
INSTALLATION PLANNING
The S
Ó
LAS THIRTY 8 uses 4x6 Direct-vent pipe.
There are two basic types of direct-vent installation:
•
Horizontal Termination
•
Vertical Termination
It is important to select the proper length of vent pipe for the type of termination you choose, taking into
consideration wall thicknesses.
FOR HORIZONTAL TERMINATION
Select the amount of vertical rise
desired. All horizontal run of venting
must have ¼” rise for every 12” of
horizontal run.
WARNING
Never run the vent pipe level or downward. This may cause
excessive temperatures which could cause a fire.
FOR VERTICAL TERMINATION
Measure the distance from the Horizontal Vent Center Line (see diagram on page 8 ). Add the ceiling
thickness, the vertical rise in an attic or second story, and allow for sufficient vent height above the
roofline.
NOTE:
You may use two 45
⁰
elbows in place of a 90
⁰
elbow. You must follow rise to run ratios when using 45
⁰
elbows. The appliance is approved for use with three 90
⁰
elbows maximum of a combination of 90
⁰
and 45
⁰
elbows up to a maximum of 270
⁰
.
For two-story applications, firestops are required at each floor level. If an offset is needed in the attic,
additional pipe and elbows will be required.
It is very important that the venting system maintain its balance between the combustion air intake and
the flue gas exhaust. Certain limitations apply to vent configurations and must be strictly followed.
INSTALLING A VENT SYSTEM IN AN OUTSIDE CHASE
A chase is a vertical box like structure built to enclose venting that runs along the outside of a building. A
chase is required for such venting.
NOTICE
Treatment of firestops and construction of the
chase may vary from building type to building
type. These instructions are not substitutes for
local building code requirements.
NOTICE
When installing in a chase, you should insulate the chase as you
would the outside walls of your home. This is especially
important in cold climates. Insulation should be considered a
combustible material. Maintain proper clearances to
combustibles.
