Venting & Grates

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.

THE MOST IMPORTANT THING TO REMEMBER ABOUT CHIMNEYS IS THEIR NEED FOR MAINTENANCE AND CLEANING. IF A CHIMNEY IS NOT CLEANED ON A FREQUENT BASIS, IT WILL AFFECT DRAFT, AS WELL AS BE A CONTRIBUTING FACTOR TO A POTENTIAL CHIMNEY FIRE.

3.3what to do if you have a problem. If you have a chimney fire:

1. Be sure everyone is out of the house.

2. Call the fire department.

3.Close the draft control on the ash door and make sure both doors on the stove are closed and latched.

4.Do not put water on the fire, this will cause un- necessary damage to the stove and flue.

5.Have the chimney inspected and repaired prior to building another fire.

Smoke puffs out of stove;

A)Check previous suggestions for insufficient draft.

B)Check draft control for proper operation.

C)Chimney may be too low. Increase height.

D)Add more fresh air to the room. Your home may be so tight that there is not enough oxygen getting to the fire.

E)Remember, open the draft control and crack the door open slightly before reloading or checking the fire.

F)Check the ashes. The ash pan and firebox may be overloaded with ashes.

G)Check the chimney cleanout door to ensure it closes properly.

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.
