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 NFPA54.
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
10.5 in. w.c.
14 in. w.c.
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).
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 qualified 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 fitter.)
Note:
A listed (and Commonwealth of Massachusetts
approved) 1/2 in. (13 mm) T-handle manual shut-off
valve and flexible 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.
Incoming gas line should be piped to the 1/2 inch con-
nection on the manual shutoff valve.
WARNING
Fire Risk
Explosion Risk
Gas build-up during line purge may ignite.
Purge should be performed by qualified
technician.
Ensure adequate ventilation.
Ensure there are no ignition sources such
as sparks or open flames.
A small amount of air will be in the gas supply lines.
When first lighting appliance it will take a short time
for air to purge from lines. Subsequent lighting of the
unit will not require such purging.
Never allow the
ON/OFF valve to remain in the open position with-
out pressing and continuing to hold igniter button
FIRST.

WARNING
Fire Risk
Explosion Risk
Verify inlet pressures.
High pressure may cause overfire
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.
