4Gas Information
A. Fuel
Before making gas connections ensure appliance being
installed is compatible with the available gas type.
B. Gas Pressure
Proper input pressures are required for optimum appli-
ance performance. Gas line sizing requirements need to
be made following NFPA51.
WARNING
Fire Risk
Explosion Risk
Verify inlet pressures.
• High pressure may cause overre condition.
• Low pressure may cause explosion.
• Verify minimum pressures when other
household gas appliances are operating.
Install regulator upstream of valve if line pressure is
greater than 1/2 psig.
Pressure requirements for appliance are shown in table
below. Minimum pressures must be met when other house-
hold gas appliances are operating.
Pressure Natural Gas Propane
Minimum Inlet Pressure 7 in. w.c. 11 in. w.c.
Maximum Inlet Pressure 14 in. w.c. 14 in. w.c.
C. Gas Connection
Note: Have the gas supply line installed in accordance
with local building codes, if any. If not, follow ANSI 223.1.
Installation should be done by a qualied installer ap-
proved and/or licensed as required by the locality. (In
the Commonwealth of Massachusetts installation must
be performed by a licensed plumber or gas tter.)
Note: A listed (and Commonwealth of Massachusetts
approved) 1/2 in. (13 mm) T-handle manual shut-off
valve and exible gas connector are connected to the
1/2 in. (13 mm) control valve inlet.
• If substituting for these components, please consult
local codes for compliance.
The appliance and its individual shutoff valve must be dis-
connected from the gas supply piping system during any
pressures in excess of 1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
WARNING
WARNING
• Incoming gas line should be piped to the 1/2 inch con-
nection on the manual shutoff valve.
Fire Risk
Explosion Risk
• Gas build-up during line purge may ignite.
• Purge should be performed by qualied
technician.
• Ensure adequate ventilation.
• Ensure there are no ignition sources such
as sparks or open ames.
• A small amount of air will be in the gas supply lines.
When rst lighting appliance it will take a short time
for air to purge from lines. Subsequent lighting of the
log set will not require such purging. Never allow the
ON/OFF valve to remain in the open position with-
out placing a burning match on top of the burner
FIRST.
CHECK FOR GAS LEAKS
Fire Risk
Explosion Risk
Asphyxiation Risk
• Check all ttings and connections.
• Do not use open ame.
• After the gas line installation is complete,
all connections must be tightened and
checked for leaks with a commercially
available, non-corrosive leak check so-
lution. Be sure to rinse off all leak check
solution following testing.
Fittings and connections may have loosened during
shipping and handling.
