*In EDV3530 corner installations, the unit
has been moved 1-3/8 in. (35 mm) into the
room in order to achieve a minimum of
5 in. (127 mm) in the F dimension.
*These dimensions occur when one 45
degree elbow is connected directly to the
Note-
Venting requirements for rear vent applications in corner installations - the horizontal vent length "a" to "b," must not exceed 28 inches (711 mm)

Step 2. ROUTING GAS LINE

Route a 1/2" (13 mm) gas line to the left side
of the appliance as shown in Figure 15. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. All appliances
are factory-equipped with a flexible gas line
connector and 1/2 inch shutoff valve. (See
Step 6 on Page 25).
Also see Figure 13.
Figure 15 - Route Gas Line
Proper Sizing of Gas Line
Properly size and route the gas supply line
from the supply regulator to the area where the
appliance is to be installed per requirements
outlined in the National Fuel Gas Code, NFPA
54 - latest edition (USA) or CAN/CSA-B149.1
- latest edition (Canada).

Never use galvanized or plastic pipe. Refer
to Table 6 for proper sizing of the gas sup-
ply line, if black iron pipe is being used. Gas
lines must be routed, constructed and made
of materials that are in strict accordance with
local codes and regulations. We recommend
that a qualified individual such as a plumber or
gas fitter be hired to correctly size and route
the gas supply line to the appliance. Installing
a gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualified should attempt sizing
or installing gas piping.

Notes:
• All appliances are factory-equipped with
a flexible gas line connector and 1/2 inch
shutoff valve (see Figure 50 on Page 25).
• See Massachusetts Requirements on Page
4 for additional requirements for installations
in the state of Massachusetts in the USA.
• The gas supply line should Not be connected
to the appliance until Step 6 (Page 25).
• A pipe joint compound rated for gas should be
used on the threaded joints. Ensure propane
resistant compounds are used in propane
applications. Be very careful that the pipe
compound does not get inside the pipe.
• It is recommended to install a sediment
trap in the supply line as close as possible
to the appliance. Appliances using Propane
should have a sediment trap at the base of
the tank.
• Check with local building official for local
code requirements (i.e. are below grade
penetrations of the gas line allowed?, etc).
IMPORTANT: If propane is used, be aware that
if tank size is too small (i.e. under 100-lbs, if
this is the only gas appliance in the dwelling.
Ref. NPFA 58), there may be loss of pressure,
resulting in insufficient fuel delivery (which
can result in sooting, severe delayed ignition
or other malfunctions). Any damage resulting
from an improper installation, such as this, is
not covered under the limited warranty.
