Vent Requirements; Adding Restriction - Jøtul GF 600 DV II Installation And Operation Instructions Manual

Venting Requirements
There are three types of venting configurations
approved for use with this appliance:
• Vertical Venting (Vertical Termination)
• Hearthmount Co-Linear (Vertical Termination)
• Horizontal Termination (Horizontal Termination)
The Jøtul GF 600 DV II Firelight is approved for
use with the 4/6 direct vent systems listed below.
Use parts of one manufacturer only - DO NOT MIX
VENT COMPONENTS FROM DIFFERENT MANUFAC-
TURERS IN THE SAME SYSTEM.
• Simpson Dura-Vent GS
• Amerivent Corporation
• Security Vent Ltd.
• Selkirk Metalbestos
Installation of any components not manufac-
tured or approved by Jøtul or failure to meet all
clearance requirements will void all warranties and
could result in property damage or bodily injury.
The approved vent configurations described in
this manual are derived from extensive testing
under controlled laboratory conditions. Gas appli-
ance performance can be negatively affected by
variables present in the installation environment,
i.e.: atmospheric pressure, strong prevailing winds,
adjacent structures and trees, snow accumulation,
etc. These conditions should be taken into consider-
ation by the installer and stove owner when plan-
ning the vent system design.
IMPORTANT
• JOINT SEALING REQUIREMENT:
APPLY A 1/8" BEAD OF HIGH-
TEMPERATURE SEALANT OR
MIL-PAC® TO THE MALE
SECTION OF THE INNER
VENT PIPE. THE CEMENT
SHOULD FORM A SEAL
BETWEEN THE INNER
AND OUTER PIPES.
• NEVER MODIFY ANY
VENTING COMPONENT, OR USE ANY
DAMAGED VENTING PRODUCT.
• THE GAS APPLIANCE AND VENT SYSTEM MUST BE
VENTED DIRECTLY TO THE OUTSIDE OF THE
BUILDING AND NEVER ATTACHED TO A CHIMNEY
SERVING A SOLID FUEL OR GAS BURNING APPLI-
ANCE. EACH DIRECT VENT GAS APPLIANCE MUST
HAVE ITS OWN SEPARATE VENT SYSTEM. COM-
MON VENT SYSTEMS ARE PROHIBITED.

• IF VENTING SYSTEM IS DISASSEMBLED FOR ANY
REASON, REINSTALL PER THE MANUFACTURER'S
INSTRUCTIONS PROVIDED FOR THE INITIAL
INSTALLATION.
Vertical Vent Requirements
The GF 600 DV II Firelight features a sliding shutter
that allows exhaust vent restriction adjustment
from outside the firebox. See fig. 5. The shutter is
set in the fully open position (A) at the factory.
The final position of the restriction shutter is
determined by your individual vent configuration as
indicated in fig. 10 on page 11. Further fine tuning
can be made to compensate for draft characteristics
that would otherwise interfere with proper burner
performance such as low heat output, weak flame
picture, or inefficient combustion.
Exhaust Restrictor Adjustment
1. Remove the Top Plate from the stove.
2. Loosen the wingnut on the Restrictor Stem and
push it to the left to align with the hash marks
on the exhaust manifold that correspond with
the appropriate setting, (B, C, or D). See figs 5 and 9.
3. After the burner has been operating for 15
minutes, make any further adjustment in 1/8"
increments until the desired flame picture is
achieved. Operate the burner for 10-15 minutes
between additional adjustments.
4. Tighten the wingnut and replace the Top Plate.
