VERTICAL THROUGH-THE-ROOF
APPLICATION/INSTALLATION
For all vertical through-the-roof installations, the supplied
flue restrictors must be installed. Install the flue restrictor
according to the settings shown in the Vertical Through-the-
Roof Installation Flue Restrictor Chart in order to balance
the airflow in and out of the unit and to maintain proper
flame height.
This gas stove 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.
Figure 38
•
Up to two 45° elbows may be used within the horizontal
run. For each 45° elbow used on the horizontal 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' (2.5 m) vertical rise is required.
(Figure 38)
•
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.
Figure 38
•
SLP-HVS supports offsets. This application will require
that you first determine the roof pitch and use the ap
-
propriate starter kit. (Refer to Venting Components
list.)
•
The maximum angular variation allowed in the system
is 270°.

For the minimum height of the vent above the highest
point of penetration through the roof refer to
