Annual Maintenance
After a period of nonuse or to keep your grill in top operating condition, you should perform the following maintenance procedures to keep the grill ready for instant use and for your safety.
•Do not obstruct the flow of combustion and ventila- tion air.
•Clean inside the grill head. Remove the burner/ venturi assembly and cover the valve orifices with a piece of aluminum foil to keep out dirt. Brush inside bottom and sides with a stiff wire brush to remove
•Test the Ignitor for a good spark. (See Rotary Spark Ignitor System in the General Maintenance section.)
•The stainless steel burner may be brushed lightly with a stiff laundry brush. Any clogged flame holes may be opened using a thin wire. Use the supplied venturi cleaning brush or a bottle brush, pipe cleaner to clean out the venturis. (See Flashback in General Maintenance.)
•Clean the Control Panel, Side Shelf Supports, Lid Handle Spacers, Lower Cart Frame, Posts with a mild detergent soap and warm water solution. For the Optimum Console use a mild detergent soap and water, Windex or a quality stainless steel cleaner such as MHP’s Stainless Steel Cleaner (Part #SSC) to clean the column and grill lid facing.
Do Not Use cleaning agents such as bleach, powdered cleansers, steel wool pads or caustic solutions like oven cleaners because they will damage the surfaces.
•Porcelain cooking grids should be cleaned by first
•Occasional white oxidation on the exterior of your grill head and lid may be washed off with mild soap and warm water.
•Severe weathering of the grill head and lid can be remedied by lightly sanding or rubbing with steel wool. Then it can be recoated with a high quality heat resistant paint similar to MHP’s
•Inspect the hose and gas fittings. Remember to leak check every time you disconnect and recon- nect a gas fitting.
•Keep the ventilation openings of the LP cylinder enclosure free and clear from debris.
Warning: Check the hose before each use of the grill for nicks, cracking, abrasions or cuts. If the hose is found to be damaged in any way, do not use the grill. Replace using only MHP authorized replacement hose.
General Maintenance
Flashback
In some areas of the country, spiders and other in- sects build nests, lay eggs and spin webs in the grill’s venturi tube or valve orifice. This obstructs the full flow of gas to the burner. Some gas backs up resulting in a “Flashback” - a fire in the venturi behind the control panel which could cause serious bodily injury or dam- age to your grill.
To remove spider webs and/or other obstructions, you must clean out the venturis. This should be done routinely if the grill has sat idle for extended peri- ods. Also, if you live in an area where spiders are plentiful, you should clean the venturis often, es- pecially in the fall when there is an increase in egg sack production.
To clean, be sure the grill is cold. Open lid and re- move the cooking grids, the briquettes and the bri- quette grate.
1.Remove the burner clip holding the burner in place. (See Fig. 42)
2.Lift burner and venturi assembly out. With sup- plied cleaning brush, a pipe cleaner or a flexible wire, clean out the venturi tube.
3.Remove hex head orifice with a 3/8" wrench. Clean Orifice hole and inner part of the valve with a toothpick. Be careful not to enlarge the orifice hole.
4.Check orifice receptacle in valve body.
When finished cleaning reassemble the complete unit.
