MULTIFUEL GRATE

GRATE

The grates in the Acorn Multifuel units comprise a
series of reciprocating cast iron bars seated on a
pivoted "comb". All bars in the grate are identical,
but every other bar is turned through 180 degrees,
with the ends of the bars marked "H" sitting on the
high sections of the comb, and the ends marked "L"
sitting on the low sections.

ASSEMBLING THE GRATE

To assemble the grate, fit bars to low sections of the
comb first, inserting end marked "H" into rear
channel with groove on underside of bar located on
upstand tab, and then lowering end marked "L"
onto the low section of the comb. The upper bar is
fitted in a similar manner, but with the end marked
"L" inserted in the rear channel, and the end
marked "H" seated on the high section of the comb.

INSTALLATION

GRATE BAR REPLACEMENT

After extended use it may be necessary to
replace some of the grate bars. 
Periodic inspection of the bars is recommended
and the removal of any nails or wire that may be
present after burning wood. All the grate bars in
each appliance are identical and can easily be
lifted out after removal of the fuel retainers.
Remove damaged grate bars and replace with
casting of the same type, fitting as per
instructions above. (Check Identification letters
on the casting when reordering).
