Grate
The grates in the Stratford Sf & Si 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 (Fig.1)
To assemble the grate, fit bars to low sections of the comb first, inserting end market "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.

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 instruction above. (Check
Identification letters on the casting when reordering).
Riddle Lever for Sf only (Fig 2a)
The riddle lever gives effective de-ashing, and also allows the grate to be set in the coal burning or wood burning
position, as indicated on the right hand side of the appliance.
For Si use the operating tool provided. Rotating the end shaft of the comb with the operating tool gives effective
de-ashing, and also allows the grate to be set in the coal or wood burning position, as indicated on the right hand
side of the appliance (Fig 2b).
