Manual Shut-Off Valve:
This installer-supplied valve must be installed in
the gas service line before the appliance in the gas
stream and in a location where it can be reached
quickly in the event of an emergency.
In Massachusetts: A “T” handle type manual valve
must be installed in the gas supply line to the
appliance.
IMPORTANT: Any conversion required must be
performed by your dealer or a qualified licensed
plumber or gas service company. Please provide
the service person with this manual before work
begins.
Pressure Regulator:
UÊ ÊÊ i>Ûއ`ÕÌÞ]ÊVœ““iÀVˆ>ÊÌÞ«iÊVœœŽˆ˜}Ê
equipment must have a pressure regulator on
the incoming service line for safe and efficient
operation, since service pressure may fluctuate
with local demand. External regulators are
not required on this oven since a regulator is
built into each unit at the factory. Under no
condition bypass this built-in regulator.

manometer, natural gas requires 5.0” W.C.P.
and LP gas requires 10.0” W.C.P. Incoming line
pressure upstream from the regulator must be
1” W.C.P. higher than the manifold pressure
in order to check the regulator. The regulator
used on these ovens can withstand a maximum
input pressure of 1/2” PSI (14.0” W.C.P.). If
the line pressure is in excess of 1/2” PSI (14.0”
W.C.P.), a step down regulator will be required.

gas supply piping system during any pressure
testing of that system.
Flexible Connections:
If the unit is to be installed with flexible couplings
and/or quick-disconnect fittings, the installer must
use a heavy-duty AGA design-certified flexible
connector of at least 1/2” (1.3 cm) ID NPT (with
suitable strain reliefs) in compliance with ANSI
Z21.41and Z21.69.
Rigid Connections:
Incoming gas is brought from an intake pipe (not
supplied) to the lower right center of the unit
to the pressure regulator. The only connection
necessary is from the service supply, through the
shut-off valve (not supplied) to this intake pipe (not
supplied) to the regulator.
In Canada: CAN 1-6, 10-88 metal connectors
for gas appliances and CAN 1-6.9 M79 quick
disconnect devices for use with gas fuel.
In Massachusetts: This appliance must be installed
with a 36” (3-foot) long flexible gas connector.
WARNING
DO NOT use the handle or oven door to lift
the oven. Remove door before installation to
ensure that it is not used to lift the unit.
WARNING
NEVER use this appliance as a space heater to
heat or warm the room. Doing so may result in
carbon monoxide poisoning and overheating of
the oven.
CAUTION
Before placing the oven into operation, always
check for gas leaks with a soapy water solution
or other acceptable method.
DO NOT USE AN
OPEN FLAME TO CHECK FOR LEAKS.
CAUTION
DO NOT use the handle or oven door to lift
the oven. DO NOT lift or carry the door by the
handle.
Removing the door must be done by your
dealer, a qualified licensed plumber, or certified
gas installer.
