Vent Guidelines
•All vent components must be installed in accor- dance with the listing terms and manufacturer’s instructions.
•Vent Height: Measured from the top of the insert to the top of the termination cap.
Minimum: no less than 10'
Maximum: no greater than 35'. See figures 9 and 10.
The minimum vent height above the roof or adjacent walls is specified by building codes. As a general guide, follow the Gas Vent Rule on page 12.
•HORIZONTAL RUNS ARE NOT PERMITTED ANY- WHERE IN THE VENTING SYSTEM.
•Venting liners used on this appliance may not be less than 3” in diameter or greater than 3” in diameter.
•Any unused flue or masonry enclosure can be used as a passageway for venting provided the flue is relined using 3” Listed flexible gas liner.
•The remaining space around the liner in a ma- sonry or
•Flexible liner components may not be exposed in any living space.
•Installation of any components not manufactured or approved by Jøtul or failure to meet all clear- ance requirements will void all warranties and could result in property damage, bodily injury, or serious fire.
•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 BUILD- ING, AND NEVER ATTACHED TO A CHIMNEY SERVING A SOLID FUEL OR GAS BURNING APPLI- ANCE.
•Variable Vent Restriction: See the System Check section on pages
IMPORTANT NOTICE:
THE USE OF AN EXISTING CHIMNEY AS AN AIR INTAKE IS NOT COVERED UN- DER THE ANSI
M99 TEST METHODS AND RESULTING ITS/WHI PRODUCT CERTIFICATION. THE CODE AUTHORITY HAVING JURIS- DICTION MUST BE CONSULTED PRIOR TO PROCEEDING WITH THIS INSTALLA- TION METHOD.
Masonry Fireplace Installation
When installing a GI425 DV Camden gas insert into a masonry fireplace the insert will be vented through dual 3” flexible gas aluminum liners.
This
One liner is attached to the Exhaust Outlet on the back of the unit and will carry the exhaust gases to the outside of the house. This exhaust liner must be directly connected to the unit and run the full length of the chimney. See figure 7.
The other 3” liner will be attached to the Air
Intake Collar on the back of the unit to provide fresh air for combustion. The Intake Collar is labeled for easy identification. The liner must extend a mini- mum of 6’ off the back of the unit and extend through the damper area of the fireplace into the tile liner of the chimney. This liner can also extend the full length of the chimney and connect to the termination cap.
IMPORTANT
If the intake flex does not extend the full length of the chimney, forming a direct connection between the unit and the termination cap, A METAL BLOCK OFF PLATE MUST BE INSTALLED to seal the air intake from room air. Normally this sealing plate will be installed within the existing fireplace damper area. See figure 7. The sealing plate is not necessary if a direct connection is made between the cap and the fireplace.
WARNING! Avoid cross venting the insert. Before installation, label both ends of the exhaust flex pipe to ensure connection to the appropriate collars on the fireplace unit and vent termination cap.
CANADA REQUIREMENT: Both the Intake and the Exhaust liners must extend the full length of the chimney and be securely connected to both the unit and the termina- tion kit.
If the fireplace has been modified to accom- modate installation, use anchors or masonry nails to attach the metal Fireplace Conver- sion Notice Plate supplied with this unit to the back wall of the masonry fireplace firebox where it will be readily seen should the insert be removed.
