In selecting the location, the aesthetic and functional use of the appliance are primary concerns.
However, vent system routing to the outside atmosphere and access to the fuel supply are also important. Consideration should be given to traffi c ways, furniture, draperies, etc., due to high surface
temperatures (see illustrations). The location should also be free of electrical, plumbing or other
heating / air conditioning ducting.
These direct vent appliances are uniquely suited for installations requiring a utility shelf positioned
directly above the fi replace. Utility shelves like these are commonly used for locating television sets
and decorative plants. Be aware that this is a heat producing appliance. Objects placed above
the unit are exposed to elevated temperatures.
If a shelf is to be installed above appliance, see Shelf Height Minimum Clearances (Figure 8 on
Page 9).
The appliance should be mounted on a fully supported base extending the full width and depth of the
appliance. The appliance may be located on or near conventional construction materials. However, if
installed on combustible materials, such as carpeting, vinyl tile, etc., a metal or wood barrier covering
the entire bottom surface of the appliance must be used.

Proper Sizing of Gas Line
level, a solid continuous platform must be
constructed. Headers may be in direct contact
with the appliance top spacers but must not be
supported by them or notched to fi t around them.
All construction above the appliance must be
self supporting, DO NOT USE THE APPLIANCE
FOR STRUCTURAL SUPPORT.
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 B149 - latest edition
(Canada). Never use galvanized or plastic pipe.
Refer to Table 8 for proper sizing of the gas
Side Nailing Flanges
The fi replace should be secured to the framing at the side(s) of the appliance using the
factory-provided nailing fl anges. Install the 8
nailing fl anges as shown in Figure 11 using the
existing screws. Position the fi replace within
the framing. When required, the tabs may be
bent 90 degrees by hand or with the assistance
of a hammer. Use wood screws to secure the

supply 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 qualifi ed individual such as a plumber
or gas fi tter 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 unqualifi ed should attempt sizing
or installing gas piping.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
• All appliances are factory-equipped with a
fl exible gas line connector and 1/2 inch shutoff
valve (see Figure 47 on Page 27).
• See Massachusetts Requirements on Page
3 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 27).
• 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 (see Figure 47). Appliances using
Propane should have a sediment trap at the
base of the tank.
• Check with local building offi cial 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 insuffi cient 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.
