Annual Maintenance
After a period of nonuse or to keep your grill in top
operating condition, you should perform the following mainte-
nance procedures to keep the grill ready for instant use and for
your safety.
Do not obstruct the flow of combustion and ventilation air.
Clean inside the grill head. Remove the burner/venturi as-
sembly 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 built-up grease and debris.
Be careful
not to damage the Ignitor or Collector Box.
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 us-
ing 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 column use a mild
detergent soap and water, Windex is also great 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.
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 BF
-1 Paint, available in spray cans from your dealer.
Inspect the hose and gas fittings. Remember to leak check
every time you disconnect and reconnect a gas fitting.
Keep the ventilation openings of the LP cylinder enclosure
free and clear from debris.
General Maintenance
Flashback
In some areas of the country, spiders and other insects 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 damage 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 periods. Also, if you live in an
area where spiders are plentiful, you should clean the ven-
turis often, especially in the fall when there is an increase
in egg sack production.
To clean, be sure the grill is cold. Open lid and remove the
cooking grids, the briquettes and the briquette grate.
1. Remove the burner clip holding the burner in place.
2. Lift burner and venturi assembly out. With supplied clean-
ing 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.
