BJWA Gas Thermostat
The BJWA control is a combination of gas cock and by-pass
type thermostat. It is available with both
by-pass and pilot adjustments. With the BJWA, the gas is
turned on, and the temperature setting is made, with a single
turn of the dial.
The BJWA can be adapted to have a multiple orientation and
number of outlets. It can be mounted above or below the
manifold via a flanged nipple.
Adjustments are on the front for by-pass and temperature
calibration.
The BJWA is typically used on US Range Ovens and griddle
and on Garland griddles.
• Ambient temperature 32°F (0°C) to 350°F (177°C)
• Maximum inlet pressure 0.5 PSI
• Capacity (Natural Gas): To 70,000 BTU/Hr
By-Pass Feature
The BJW has a by-pass feature which when the appliance
reaches the temperature at which the dial is set, the control
cuts down the flow of gas to the amount required to keep
the appliance at that temperature. However, the control
must by pass enough gas to keep the entire burner lighted.
To maintain this minimum flame, the by-pass must be set
carefully and accurately. Instructions on setting the by-pass
feature on the BJWA are as follows:
1. Light the burner, then turn the dial to “FULL ON”.
2. After 5 minutes, turn the dial clockwise to a point slightly
beyond the first mark on the dial.
3. Remove the dial and bezel.
4. With a screwdriver, turn the by-pass adjuster – counter-
clockwise to increase the flame, clockwise to decrease it,
until there is a minimum blue stable blue flame over the
entire ported area of the burner.
5. Replace the bezel and dial, turning the dial clockwise,
until it locks in the “OFF” position.
D. Insure that the temperature bulb is secured in the
capillary guard holder as shown:
3. Check for leaks
4. Perform an operational check of the new control using
your pyrometer as a crosscheck. Temperature recovery
should be most responsive when initial temperature
setting is set to 400 ° F. Temperature swings of ± 30 ° F at
this temperature should be no longer than thirty minutes
when heating a cool unit.
NOTE: For complete Sit Control installation instructions refer
to Garland Service for an installation DVD.
