LIGHTING INSTRUCTIONS
The appliance is equipped with standing pilots; each pilot is located next to each of the burners. Pilots should be
lighted immediately after the gas is turned on by the manual shutoff valve.
1. Turn control knobs to "OFF" position.
2. Light pilot with a lighted taper.
3 The pilot valves are located on the manifold installed
at the front of the unit behind the front panel. For
access to the valves
4. Loosen the set screws securing the knobs in position,
and remove the knobs. Remove the front panel,
which is attached to the frame with 4 sheet metal
screws.
5. Turn the adjustment screws on the front of the pilot
valves. The pilots should be adjusted to blue short
flame (1/4" high) to have good ignition to the burners.
Repeat for remaining pilots.
6. If the pilot(s) is out turn off gas, wait 5 minutes and
repeat steps (1) through (5).
ADJUSTING BURNERS
7. With control valve for the front burner turned to
full "ON" position, close the air shutters to give a
soft blue flame having luminous tips and open to a
point where the yellow tips disappear, then tighten
the locking screws. Repeat this procedure with the
remaining burners.
8. Install the front panel to the front of the frame & reconnect and secure the knobs back into position.
ADJUSTING UNIT FOR USE ON PROPANE GAS
Units are shipped with orifices and pressure regulator for operation with natural gas (6" water column). To convert
unit from natural to propane gas follow these instructions (Note: LP models are factory set for propane gas and do
not require a conversion. These can be converted to natural gas using the natural gas orifices and converting the
regulator to natural gas):
1. Set regulator outlet pressure to 10" water column. A 1/8" pipe plug on the manifold can be removed for
attaching a pressure gauge. Remove the slotted cover from the pressure regulator and invert the plug.
Replace the cover on the regulator and plug on the manifold. Regulator is now set at 10" W.C.
2. Remove natural gas orifices, #46 for all models and install propane orifices, painted black, (#54 for all models)
located in a bag on the outside of the front panel. In order to remove natural gas orifices:
a. Remove grates and burners.
b. Remove orifices from the control valves and fittings on extended gas pipes, replace with the propane orifices.
c. Install burners and grates.
OPERATING PROCEDURE
Each burner will deliver up to 22,000 BTU/HR of heat on all models except 601SPRD (on 601SPRD each burner
is rated 55,000 BTU/HR for natural gas and 45,000 BTU/HR for propane) and is controlled by a manual On/Off
valve. The right control knob controls the front burner and the left control knob controls the rear burner on all models
except 601SPRD. On the 601SPRD, the right control knob controls the inner burner and the left control knob
controls the outer burner. After the pilot is once lit and adjusted, the burners will ignite automatically by turning the
control knob to any position between On and Off.
CLEANING THE EXTERIOR (Stainless Steel Only)
The exterior surface can be kept clean and attractive by regularly wiping it with a clean soft cloth. Any discoloration
can be removed with a non-abrasive cleaner. The burner grates and trough tray can be removed for cleaning.
