Do not burn coal on the wood grate. An 

optional coal grate kit 

is available for the Oval (#1500) and the SweetHeart (#4500) 

to burn coal. An installation and operating manual is packed 

with every Oval and Sweetheart Coal Kit. Extra copies may 

be obtained from your dealer or by contacting AGA Marvel. 

Below is a brief description of the coal kit installation

To install the optional coal grates, remove the lift handle, the 

key plate and lids. Lift the wood grate out through the top of 

the firebox and replace it with the coal grate. Remove small 

front brick in firebox by unscrewing bolt & nut that holds brick 

in place. (Please note that older models require front fire brick 

to be installed with the groove facing away from the firebox 

and towards the front of the stove). Replace with large brick 

in coal kit. Gently tap the coal grate down until it fits snugly 

into the steel track. Replace the key plate, lift handle and lids. 

Then proceed with firedoor damper installation.

To install the optional coal grate package, remove the wood 

grate through the ash pan door and replace with the coal 

grate. Remove the key plate over the firebox and slide the coal 

liners #1470 in the front and #1475 in the back of the firebox. 

Replace the key plate, lift handle and lids. Then proceed with 

firedoor damper installation.

(Coal burning only, see illustration on next column)

The firedoor damper comes with each coal kit and must be 

installed. Remove the nickel firedoor frame from the firedoor. 

Loosen the three screws that hold the cover plate over the 

damper holes. Replace the cover plate with the coal damper, 

lettered side out. Tighten screws just enough to hold the damper 

plate on but also allow it to slide freely back and forth. Lock 

screws in position with a nut on each screw thread.

A chimney 6” (15.25 cm) in diameter is imperative for the 

Coal Burning process. On chimney larger than 6” (15.25 

cm) in diameter will cause poor ignition of the coal due to 

inadequate draft. 
It is possible to burn coal with a large diameter chimney, but 

banking a new bed of coals will require a greater mix of wood 

to create and maintain an adequate draft.
The minimum draft required to maintain an oven temperature 

of 350 ºF (175⁰C) is around .04” (1.016 mm) on a water 

column. For drafts under .04” (1.016 mm) on a water column, 

closing the oven draft damper more than half way, will cause 

back puffing. 
During the recharge phase of a new bank, a draft of .08” (2.03 

mm) should be maintained for at least 10-15 minutes or until 

a substantial bed of red embers is built up.
We recommend burning anthracite coal, which is relatively 

clean to handle, burns evenly with a low flame, has a low 

sulphur content and produces relatively little smoke. 
Use a “chess nut” or “nut” size of coal, which is 1 3/16 to 1 

5/8 in (3 cm to 4.13 cm) diameter. However, other coal, such 

as bituminous, can be burned, but is inferior to anthracite.
