GRILL BURNER CLEANING:
Clean the exterior of the burner with a stainless steel wire brush. Clear
stubborn scale with a metal scraper. Clear any clogged ports with a
straightened paper clip. Never use a wooden toothpick as it may break
off and clog the port. Shake out any debris through the air shutter open-
ing (Fig. 55). Use a flashlight to inspect the burner inlet to ensure it is not
blocked. If obstructions can be seen, use a metal wire coat hanger that has
been straightened (See Fig. 56).
INJECTOR CLEANING:
Injectors should be checked for signs of blockage twice every year. As
injector removal requires a special tool, this must be done by a qualified
gas fitter only. Removal of injectors by an unqualified person may create a
hazardous situation.
TO REPLACE THE GRILL BURNERS AFTER CLEANING
1. With the burner held at a 45 degree angle front to back, lower each grill burner back into place, ensuring that the
burner inlet is centred on the injector inside the valve hole in the front (Fig. 57), and that the burner slides into
the collector box on the side, as shown in Fig. 58.
2. With the burner inlet and side properly in place, locate the tabs at the rear of the burner into the matching slots
on the support bracket. Check that the burner is level and does
not rock.
3. Refit the clamps and fixing screws to secure the burner in place.
4. Light all the burners and check for proper flame characteristics.
If adjustments are necessary, refer to the ‘Burner adjustment’
page in the ‘Installation’ section.
5. Once you have verified that the burners function correctly,
replace the grease shields, radiant trays, and grill grates.
