Venting Requirements
The Jøtul GF 400 DV Sebago gas stove may be installed with a vertical or horizontal termination and must conform to the configuration requirements described below.
This appliance is approved for use with vent systems from the following manufacturers:
•Simpson
•Amerivent Corporation
•Security Vent Ltd.
•Selkirk Metalbestos
Use parts of one manufacturer only - DO NOT MIX VENT COMPONENTS FROM DIFFERENT MANUFACTURERS IN THE SAME SYSTEM.
Installation of any components not manufactured or approved by Jøtul or failure to meet all clearance require- ments will void all warranties and could result in prop- erty damage, bodily injury, or serious fire.
The approved vent configurations described in this manual are derived from extensive testing under con- trolled laboratory conditions. Gas appliance 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 consideration by the installer and stove owner when planning the vent system design.
IMPORTANT
•JOINT SEALING REQUIREMENT: APPLY A 1/8” BEAD OF HIGH-
TEMPERATURE (750°F) SEALANT TO THE MALE SEC- TION 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 DAM- AGED VENTING PRODUCT.

Vent Restriction
The GF 400 DV Sebago is equipped with Restrictor Plates which enable you to regulate the flow of incoming combustion air and exhaust gas. The plates prevent overly strong draft that can cause poor combustion and weak flame picture. Follow the guidelines below, and on the following pages, to determine the correct restrictor plate setting for your particular installation configura- tion.
Intake Air Restrictor
This plate is located at the rear of the firebox behind the burner plate. It is set in a CLOSED position at the factory and should be left there for most vent configurations.
It should be opened only for snorkel terminations and some short run horizontal terminations as specified on the following pages. To adjust the Air Restrictor to the OPEN position, locate and loosen the wing nut under the burner and push it back as far as it will go. See Fig. 6.
Exhaust Restrictor
The Exhaust Restrictor is an adjustable shutter located at the top of the firebox. It is adjusted by moving a pivot pin into one of four positions. It is set in the FULLY OPEN position at the factory. See Fig. 7.
Use the chart in Table 1 to determine the correct position for your installation and follow the instructions below to adjust it if necessary.
Additional restriction may be needed depending the overall vent height. Use Simpson
Adjusting Exhaust Restrictor Plate:
1.Remove the Top Plate.
2.Locate the pivot pin at the left side of the firebox top. Loosen the wing nut on the pivot pin and push the pin to the left to disengage it from the current setting position. Move the pin toward the rear and then right to engage it in the appropriate position indicated on the firebox. See fig. 7.
3.Tighten the lock nut and replace the Top Plate.
