given for method #1, with the difference being that there is no ash dump door allowing
outside air into the unit. Instead, the unit will pull combustion air from within the
fireplace cavity and may possibly pick up debris and fly ash, therefore requiring more
frequent cleaning and maintenance of the air flow system. Seal the unit accordingly.
FIREPLACE INSPECTION
1- Examine the masonry fireplace and chimney to determine that it is free from cracks,
loose mortar, creosote deposits or other blockages and other signs of deterioration.
Correct any situations that warrant repair before proceeding with the installation.
2- Verify that there is a hearth extension, extending at least 18 inches in front of the
fireplace opening, and at least 8 inches to the sides of the fireplace opening. A fireplace
that has more that 6 sq ft. should have a hearth that extends 20 inches in front of the
opening and at least 12 inches to either sides of the opening.
3- If your fireplace has wooden trim above it, or a wooden mantle, it must be located so
there are at least 12 inches between the top of the Grain Comfort and any part of the trim
of the mantle, including supports.
FIREPLACE PREPARATION
1- Locate furniture and other materials a minimum of 36 inches from the front of the
fireplace to allow access and cover the hearth and adjacent areas with a drop cloth to
protect from soiling or marring the surface.
2- Thoroughly clean the fireplace and chimney of ashes and soot.
3- Remove the existing fireplace damper plate.
MINIMUM FIREPLACE CLEARANCES
Required Fireplace Dimensions: The minimum dimensions required are:
Height 24 inches
Width 26-38 inches
Depth 18 inches
SEALING THE GRAIN COMFORT STOVE
1- Place a fire resistant flexible insulation strip (1” wide 1/2" thick, backed with adhesive)
on the back of the panel, across the top and down both sides. Insulation is required to
give a positive seal.
2- Center the Grain Comfort relative to the fireplace opening
