Important Pre-installation Information
Check to be sure the fi replace meets venting and
construction requirements for the installation
of the Real-Fyre
®
gas log set (see FIREPLACE
REQUIREMENTS section, below).
This burner may only be connected to natural
gas.
Be sure the gas log set is properly sized for the
fi replace. Improper sizing may negatively impact the
proper drafting of the fi replace. Additionally, too large
a log set will adversely affect the burn and hamper the
proper operation of the control system. Fig. 5-1 illustrates
the critical dimensions of the fi rebox.
This gas log set must be installed by an NFI
Certifi ed or other qualifi ed professional installer.
The installation, including provisions for combustion
and ventilation air, must conform with local codes, or, in
the absence of local codes, with the latest edition of the
National Fuel Gas Code, ANSI Z223-1, and NFPA54.
Keep the appliance area clear and free from combustible
materials, gasoline, and other fl ammable vapors and
liquids.
The Real-Fyre
®
gas log is to be installed only in a fully
vented, fi replace with an open damper. The chimney
must be free of any obstructions. The fi replace must be
designed and approved to burn wood. The fi replace fl ue
must be at least 8" at its smallest dimension.
The fi replace must have a gas supply line that has been
installed by a qualifi ed technician in accordance with all
local codes. The gas supply line must be ½" minimum
interior diameter. If the gas line to the fi replace is longer
than 5', a larger diameter line may be necessary.
Be sure to clean the fi replace fl oor of any ashes or other
foreign materials. It is recommended that the fi replace
and chimney be inspected by a chimney sweep or other
qualifi ed person before you install the Real-Fyre
®
gas
log set.
Required Gas Pressure: The minimum inlet gas
supply pressure for the purpose of input adjustment is
Fireplace Requirements
5" of water column (w.c.) for natural gas. The maximum
inlet gas supply pressure is 10.5" w.c. for natural gas.
Testing the Gas Supply System: The gas log set and its
individual shut-off valve must be disconnected from the
gas supply piping system while performing any tests of the
piping system at pressures in excess of ½ psig. The gas
log set must be isolated from the gas supply piping system
by closing its individual manual shut-off valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig. This is accomplished
by closing the gas supply line valve required by NFPA 54.
A fi replace screen must be in place when the appliance
is in operation and, unless other provisions are provided,
the screen shall have an opening(s) for introduction of
combustion air. When glass fi replace doors are used,
operate the gas log set with the doors open.
Note: It is recommended that complete fi rebox dimensions
be obtained to ensure proper sizing.
Important: To comply with building code acceptances, and for safe operation and proper performance of this
log set, use ONLY Peterson Real-Fyre
®
parts and accessories. Use of other controls, parts, and
accessories which are not designed for use with Real-Fyre
®
gas log sets is prohibited and will
void all warranties, certifi cations, listings, and building code approvals, and may cause property
damage, personal injury, or loss of life.
