its individual manual shut off valve during any pressure testing at the gas
supply piping system at test pressures equal to or less than 1/2” psig
(3.45KPA).

INSTALLATION INSTRUCTIONS
Models CW41, CW61, CW100, C131, CW51
The installation must conform with local codes, or in the absence of local
codes, with the National Fuel Code, ANSI Z223.1/NPA 54, Or the National
Gas and Propane Installation Code, CSA B149.1 - Latest Edition.
(All Models)
The appliance should be connected ONLY to the type of gas for which it is
equipped. All equipment is adjusted at the factory. Check type of gas on the
serial plated in the compartment below the oven door.
1. Place oven in desired location and level, using adjustable legs.
Then properly tighten lock nuts. Refer to “Set up” Instructions on page 4.
NOTE: On all threaded connections the pipe joint compound must be
approved for using on Natural and Propane gases.
3. Canopies are set over ovens for ventilation purposes. A strong exhaust
fan may create a vacuum in the room and may interfere with the burner
performance, check with the fan “OFF”.
and ventilation air are not obstructed. Provisions for an adequate air
supply must also be provided. Do not obstruct the front of the unit just
below the oven door, as air for combustion enters here.
Minimum clearance for combustible and noncombustible construction.
6” from sides
6” from rear
No additional clearance from the side and back is required for service, as
the units are serviceable from the front.
4. Legs have been packed inside the oven. Legs screw into the pads under
the unit base with bolts provided.
INSTALLATION INSTRUCTIONS, cont.
5. Install pressure regulator supplied with ovens. An adequate gas supply
is imperative, so that a manifold pressure of 4” WC for natural gas and 10”
WC for Propane units can be manifold pressure of 4” WC for Natural gas
and 10” WC for Propane units can be maintained with all units operating.

7. To light pilot; open front access door, depress red button on the pilot
safety valve and light pilot burner. Maintain pressure on red button for 30
to 45 seconds, then release. If pilot goes out, repeat above procedure.
for the unit to operate.
9. Necessary adjustments have been made at the factory; however, units
should be checked at the place of installation to allow for local conditions.
10. Turn burner valve “ON” set thermostat to desired temperature, make
sure burner ignites before leaving the room.
12. During normal operation; if the pilot goes out, wait 5 minutes before
attempting to relight the oven. This allows any accumulated gas to
dissipate.
13. To shut oven down, turn thermostat and oven burner valve to the “OFF”
position. Disconnect gas supply after pilot has gone out. Repeat steps 6
and 10 to relight.

CW SERIES LIGHTING AND SHUT DOWN INSTRUCTIONS
Before turning gas supply on, make sure all control valves are in the “OFF”
position.
WARNING
All adjusting and service should be performed by a person
knowledgeable in making such adjustments. If in doubt, call
Peerless, a Peerless representative, or the local service company to
perform maintenance and repairs.
LIGHTING AND SHUT DOWN PROCEDURES
1. Open access door, depress red button on safety valve and light pilot.
2. Hold button in for 30 to 45 seconds, then release. If pilot goes out wait
5 minutes and repeat procedure.
NOTE: The lighting procedure is also inside lower access panel.
4. For daily shut down turn burner valve to the “OFF” position. For complete
shut down turn burner valve “OFF” and extinguish pilots.
NOTE: Keep area surrounding oven free and clear of combustibles. All
ventilation air are not obstructed. Provisions for an adequate air supply must
also be provided. Do not obstruct the front of the unit just below the oven
door, as air for combustion enters here.
NOTE:
oven will smoke considerably. It is nothing but the oil coating on the steel
parts. Allow good ventilation during this period.
For other important information concerning the operation of your oven, refer
to the Robertshaw bulletins in this booklet. (By-Pass, Calibration, etc.)
NOTE: Calibration is not covered by warranty.
