139775_R03_GI 535 DV IPI June 2016
7.0 Fireplace Assembly
Before beginning final assembly, push the insert into
the fireplace and adjust the leveling bolts located at
each corner as appropriate to achieve a level and plumb
installation.
Complete the assembly procedures in this order:
1.
Gas Connection and Leak Test
2.
Gas Pressure Test
3.
Fuel Conversion
4.
High Altitude Adjustment
5.
Brick Panel or Reflective Glass Panel Kits
6.
Log Set
7.
Air Shutter Adjustment
NOTE: IN ORDER EASE ACCESS TO COMPONENTS,
COMPLETE PROCEDURES 1-4 ABOVE BEFORE
PLACING THE INSERT WITHIN THE FIREPLACE.
7.1 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. 7.1-7.2.
The GI 535 DV IPI is shipped with a 36" length of
3/8" flexible gas line to ease installation and service.
However, for those areas where flexible gas lines are
not permitted, use of a 3/8" iron nipple and union is
recommended. See fig. 7.1.
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.
An integrated gas cock is built into the fuel supply
line just upstream of the valve. This feature conforms
to building codes requiring a shut-off valve be located
within the same room as the appliance. The gas cock
allows for the disconnection of the insert for servicing
and maintenance. See figs. 7.2.
Secure all joints tightly using appropriate tools
and sealing compounds (for propane units, be sure to
use compounds that are propane resistant). Turn on
gas supply and test for gas leaks using a soapy water
solution or electronic gas sensor. Never use an open
flame to check for leaks. Tighten or reconnect the
leaking joint and retest for any gas leaks.

7.2 Gas Pressure Test
Correct gas pressure is essential for efficient and
safe operation of the gas insert. It is important that
the correct pressure is established at the time of the
installation.
The appliance must be isolated from the gas supply
line by closing its internal manual gas shut-off valve (gas
cock) during any pressure testing of the gas supply piping
system that is equal to or exceeds pressures
of 1/2 psig (3.5kPa).
1. Use the Glass Frame Latch Tool to open and close the
internal gas cock located on the supply line in the
valve compartment. See fig. 7.3.
2. Connect a manometer to the Inlet and Manifold
test connection points located on the face of the
Control Valve. See fig. 7.4. Adjust the pressure to
the appropriate specifications indicated in the chart
below.
INLET or supply pressure (the amount of gas coming to
the valve.) Indicated by the arrow embossed on the
valve.
OUT - for manifold pressure (the amount of gas that is
coming out of the valve to the burner.)
