operation of the Katahdin gas insert. It is important
that the correct gas pressure be established at the time
of the installation. For more details, see the Gas
Pressure section of this manual on page 14.

Gas Supply Connection

The gas supply line connection is made to the valve on
the left side of the unit facing the front. The gas supply
line should be a minimum of 3/8" in diameter, or the
appropriate size to provide sufficient gas pressure to
the valve regardless of the input setting.
See fig. 11 and 12.
For your convience the GI 450 DV Katahdin is
shipped with a short piece of 3/8" iron and a 24" length
of flexible gas line. Jotul recommends the use of the
flexible gas line for ease of installation and service.
However, for those areas where flexible gas lines are
not permitted use of the 3/8" iron is recommended. See
fig. 12.
The use of Flexible Gas Appliance Connectors is
acceptable in many areas in the U.S., however, Canadian
methods vary depending on local code.
ALL INSTALLATIONS MUST COMPLY WITH LOCAL
CODE OR IN THE ABSENCE OF LOCAL CODE, MUST
COMPLY WITH THE MOST RECENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR
CAN-B149.
All codes require: a gas shut-off valve (gas cock)
.union, to be installed in the supply line, and in the same
room as the appliance. This allows for the disconnection
of the insert for servicing and maintenance. See fig. 12.
T-handle gas cocks are required in Massachusetts
in compliance with code 248CMR.
