BE CAREFUL not to do anything to make the hole in the orifice bigger.
Click here for more information on how to access the orifice. CLEAN OUT THE BURNER: The cast-iron burner, especially on grills a couple of years old, can become obstructed by a rusty powder and thin flakes that will not allow the gas and air to mix properly.
Once you have access to the gas valve, remove the regulator hose. Grasp the flat part of the gas valve with one wrench and hold it tightly. Then, loosen the flat lock nut located at the end of the valve next to the air shutter.
Run a broom straw or some other small rod through the orifice to make sure it is clean.If you don't have a shop-vac, have someone help you tip the grill forward until the powder and flakes fall out.Reattach insect screen, air shutter, orifice and gas valve and make sure all connections are snug. Be sure to spray all hose connections with soapy water to check for leaks.Click on the links below to watch short HOW TO VIDEOS on how to perform routine maintenance and service procedures on your Holland Grill to help keep it in tip-top shape.HOW TO adjust the air shutter HOW TO purge the regulator HOW TO change the orifice HOW TO test for gas leaks HOW TO change the propane tank HOW TO adjust the igniter assembly HOW TO clean the burner HOW TO replace the igniter assembly HOW TO clean your grill HOW TO light your grill HOW TO install a Searmate HOW TO manually light your grill The Holland Grill is designed to grill at approximately 400 degrees.But first, you must be able to answer a simple question...

(The grill may get as high as 475 in the very hot summer) If you get a similar reading, then your grill is doing what it should do.To access the orifice you must unscrew the gas valve from the burner.On models with an igniter, you must first remove the four screws holding the control panel on before you can unscrew the gas valve.NOTE: OBSERVE ALL SAFETY PRECAUTIONS WHEN WORKING WITH GAS.REFER TO YOUR OWNER'S MANUAL OR CALL HOLLAND'S CUSTOMER SERVICE LINE. IMPROPER LIGHTING SEQUENCE: Because of the safety valve installed in all LP regulator hoses, the Holland Grill must be turned on and off the same way every time.
