E. Improperly sized flue - Too small of a chimney is incapable
of moving the volume of air necessary. Too large of a flue
could have trouble warming up to create the necessary
upward flow.
F. Chimney offsets - offset chimneys should be avoided if
possible. Not only can the offset affect draft, it is also a
place for debris to collect over time.
G. Too many elbows - The flue connector has more than two
elbows in it. Sometimes, depending on overall chimney
performance, one elbow could be too many.
H. Vent sharing - No more than one heating appliance shall
vent into a single flue.

4. Grates
4.1 GRATE SYSTEM AND CONTROLS.
The Grates are made of heavy-duty cast iron. The function
of the grate system is to support the coal while allowing air
flow through the fire. The grate system also allows removal
of the ashes by shaking them through the grates.
The grates are removable without the use of tools, once
the fire bricks are removed, the grates simply lift out. Lift
the right end higher to disengage from the shaking link. To
re-install the grates, lower them, one at a time, left end first,
be sure the grate hooks into the grate link as you drop it into
place.
Your grates will last forever, as long as you keep your ashes
cleaned out of the stove. When ashes are left pile-up against
the grates, the air-flow is blocked. With no air flow through
the grates, they will begin to sag from the intense heat.
The grates are designed to accommodate three different
sizes of anthracite coal. Pea is defined as being able to fit
through a round screen hole of 9/16” to 7/8”. Nut or Chestnut
is defined as being able to fit through a round screen hole of
7/8” to 1½”. Finally, Stove coal which is 1½” to 2½” in size.
Pea or Nut you’ll find work the best for starting a fire, while
all three sizes burn just as well.
The external shaker handle allows for greater safety from
burns, and the convenience of needing no extra tools.
