2. GENERAL INSTALLATION INSTRUCTIONS:
Ensure gas supply and gas type, as shown on unit data plate agree. (Data plate is located on the right side
panel of unit).
Unit installation must conform with the National Fuel Gas Code, ANSI Z223.1-1996, the National Gas
Installation Code, CAN/CGA-B149.1, or the Propane Installation Code, CAN/CGA-B149.2 as applicable
and in accordance with local codes.
Screw legs intothe permanently fastened nuts on the four corners of the unit and tightenby hand. Level the
unit by turning the adjustment screw at the bottom of each leg. Do not slide unit with legs mounted, lift if
necessary to move unit.
Pipe gas supply to unit.
Pipe threading compound must be resistant to the action of liquefied petroleum gases.
These units are suitable for installation on combustible andnoncombustible surfaces.
Warning: DO NOT use an open flame to check for leaks. Check all gas piping for leaks
!
with a soap and water solution before operatingunit.
Lighting instructions are located on the rear panel. Access to the pilot valves are gained through openings
in the front panel. Access to the pilot burner isgained by removing thetop grate.
Lighting Pilot Burner:
1.Turn all burners to the “OFF” position.
2.Turn on the main gas supply to the unit.
3.Light the pilot and adjust the pilot regulatingvalve to give astable pilot flame.
4.If the pilot is out, turn all control knobs to the “OFF’ position. Wait 5 minutes before attempting to
light the pilot.
5.To adjust the pilot flame, turn adjusting screw on the pilot valve to increase or decrease the size of
the pilot flame. Adjust until the pilot flame is approximately½” (1 2mm) to3/4” (19mm) tall.
Burner Ignition
Since the burner is lit from a constantly burning pilot, turn the control knob to “HI” to put the unit into
operation; then adjust to any desired position between“LO” and “HI”.
Main Burner Air Supply:
For efficient burner operation, a proper balance of gas volume and primary air supply must be
maintained which will result in complete combustion. Insufficient air supply results in a yellow
streaming flame. Primary air supply is controlled by an airshutter on the burner.
Loosen the screws on the front of the venturi, and adjust the air shutter to eliminate the yellow on
the burner flame. Lock the airshutter in place bytightening the screws.
All burners are lit from constantly burning pilots, turning the control valve as desired is all that is
required to put the unit in service.
Do not permit fans to blow directly on the unit. Wherever possible, avoid open windows next to the
unit’s sides or back. Avoid wall type fans which create aircross-currents within the room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the
amount of air removed by any ventilating system. Otherwise, a subnormal atmosphere will occur,
adversely affecting operation andcausing undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or
area in which the unit is installed, and will leave the unit independent of changingdraft conditions.
All valves must be checked and lubricated periodically.Consult the authorized service
representative in your area.
1.Thoroughly clean back, sides, top and front ofunit.
2.Clean grates daily.

Weekly:
1.Clean unit thoroughly. Clean stainless steel or chromed surfaces with a damp cloth and polish with
a soft, dry cloth. A detergent may be used for cleaning. To remove discolorations, use a nonabrasive cleaner.
2.To clean the drip pan: Remove the drip pan by grabbing the handle and pulling it out of the opening
in the front panel. To replace thepan, reverse this procedure.
3.Burner air shutter openings must be kept clean.
4.Main burner ports must be kept clean. To clean burners, boil them in a strong solution of lye water
for 15 to 20 minutes. Then either brush with a wire brush or clean gas ports with a sharp-pointed
metal instrument to insureopen ports.
For conversion from natural gas to propane (L.P.).
This conversion should be done before connecting theunit to the gassupply.
1.Remove the knobs and front panel.
2.Remove the main burners.
3.Remove the orifice fittings from the valves.
4.Replace the orifice fittings with the size recommendedfor propane (L.P.).
5.Replace the main burners.
6.Before installing the regulator, remove the cap. With the brass portion of the cap up, you can read
(NAT) on the plastic insert. Snap the insert out of the cap, flip it over and snap back in place. You can
now read (L.P.). Or change the regulator to a L.P. Regulator.
7.Replace the front panel and knobs.
8.Continue with the installation.
Note:
Manifold pressure should be checked after the unit is connected to the gas supply. It should be 10
inches (25.4 cm) water column for (L.P.). If not, you can adjust the regulator by turning the white,
plastic insert in the regulator stem: Clockwise increases pressure and counter-clockwise
decreases pressure.
Manifold pressure should be 6 inches (15.2cm) watercolumn for Natural gas. Leak test all joints.
If you should have any questions or problems, contact your nearest APW Wyott Service
Representative.
