CHIMNEY VENT INSTALATION
If an existin chimney is used, these conditions must be met:
1- It must be inspected prior to use by your local buildin inspector.
10

2- A 3” (inch) diameter ri id exhaust pipe must be installed to the top of the chimney or to a
minimum of 10’ (feet).
3- A 6” ri id or flexible pipe must be installed from stove to chimney openin to allow for
fresh air intake.
4- The chimney must have a vent cap.
5- All connections should be sealed to prevent leaka e.
6- This unit can not be connected into a chimney flue or pipe servin another appliance.
FIREPLACE INSTALLATION
If this method is used the unit must be sealed air ti ht a ainst the fireplace openin to
prevent combustion air from bein drawn from within the house.
*Before installing the Grain Comfort Plus, measure to be sure the stove will cover
the openin of the fireplace. If the stove does not cover the openin , installation cannot be done.
*If the Grain Comfort Plus is used as fireplace insert, it must be installed in a fireplace, which
satisfies the requirements of the National Fireplace Protection Association (NFPA 211) in the
United States or the CSA B365 in Canada.
Followin are su ested methods of installin the Grain Comfort Plus into a masonry fireplace.
The method you use depends on what type of fireplace hearth is in your home.
1- If the fireplace hearth is equipped with an ash dump, the door over the ash dump hole
should be removed and the plate or cover on the outside removed. Thorou hly clean the
dump of all ashes and debris. Fabricate a screen of 3/8”, or less, expanded metal or screen
and cover outside hole to prevent rodents, birds, etc. from enterin . Back inside the
home—measure the location of the ash dump openin in relation to the stove bottom.
2- If it is determined that the stove will block the trap door, then the unit must be raised
approximately 1/2 inch to allow fresh combustion air to enter the fireplace area and to be
drawn into the unit. Any suitable non-combustible shim such as 1/2" an le iron may be
used to raise the unit. If the ash dump openin is far enou h to the rear of the hearth so
that it will not be covered by the stove bottom, then it is not necessary to raise the unit off
the hearth.
3- Before insertin the unit, attach a 3-inch diameter elbow to the unit’s 3-inch exhaust
pipe. Increase the pipes diameter to 6 inches by usin a 3 to 6 inch pipe increaser.
Measure and cut a section of 6-inch smooth or steel stovepipe lon enou h to carry the
exhaust above the smoke shelf (damper area) of the chimney. The pipes connections
should be secured with screws to prevent it from comin loose durin installation. Guide
the pipe up the chimney and slide the stove into the fireplace.
4- The method of insertin a unit into a fireplace without an ash dump is simpler but may
require inspection and maintenance on a more frequent basis. Follow the instructions
11

iven for method #1, with the difference bein that there is no ash dump door allowin
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 requirin more
frequent cleanin and maintenance of the air flow system. Seal the unit accordin ly.
FIREPLACE INSPECTION
1- Examine the masonry fireplace and chimney to determine that it is free from cracks,
loose mortar, creosote deposits or other blocka es and other si ns of deterioration.
Correct any situations that warrant repair before proceedin with the installation.
2- Verify that there is a hearth extension, extendin at least 18 inches in front of the
fireplace openin , and at least 8 inches to the sides of the fireplace openin . A fireplace
that has more that 6 sq ft. should have a hearth that extends 20 inches in front of the
openin and at least 12 inches to either sides of the openin .
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, includin 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 soilin or marrin the surface.
2- Thorou hly clean the fireplace and chimney of ashes and soot.
3- Remove the existin fireplace damper plate.
MINIM M FIREPLACE CLEARANCES
Required Fireplace Dimensions: The minimum dimensions required are:
Hei ht 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
ive a positive seal.
2- Center the Grain Comfort relative to the fireplace openin
12

3- Slide the unit into position in the fireplace makin sure the insulation is depressed a ainst
the masonry and sealin all ed es of the Stove.
4- This step is important not only to prevent loss of warm room air but also to restrict Back
Draft.
ALTERNATIVE INSTALLATIONS
1- There are variations to most of the referenced installations mentioned in this manual.
2- Should you have any questions your installer or dealer will most likely know the best
approach for your situation.
3- Also feel free to call Grain Stoves Inc. if you are unsure about the procedures listed.

SPECIAL NOTE
NOTE: Your STOVE WILL NOT FEED FUEL UNTIL the Internal Temperature reaches 120
degrees. This normally takes 10– 15 minutes.
After the Thermal Switch reaches 120 de rees, the Au er will start to feed Fuel at the Rate you
have set the Feed Control. The Circulation Fan will also start (assumin the Fan Control Switch
is turned on) and blow at the speed you have set the Fan Control.
NOTE: If au er is not full of Fuel, it may be necessary to hand feed the fire with a small amount
of fuel until the au er be ins to deliver fuel to the burner. Care should be taken when hand
feedin . Open the door slowly and add a small amount of fuel to the burner and continue the
process of hand feedin until you see the fuel drop into burner. This may be necessary on the
first li htin because the Au er is not “primed”. This action will be necessary if the Hopper runs
dry.
IT IS ADVISABLE TO T RN OFF THE POWER SWITCH WHEN YO
INTEND TO OPEN THE FRONT DOOR. This turns off the Circulation fan
and minimizes ash and smoke escaping. ALWAYS BE
CAREF L WHEN THE FRONT DOOR IS OPEN

DAILY MAINTENANCE – GRAIN – cont
TIP: A quantity of Clinkers can “pile up “in the Firebox area and be cleaned out on a
weekly basis. For best results, we recommend removin the clinker every 12-18 hours. This can
be accomplished while a fire is burnin , but needs to be done quickly (approximately 30
seconds) to restore fuel and air to firebox. Clinkers are a function of burnin Grains.

BI- WEEKLY MAINTENANCE
In some cases the fuel you burn may contain a lot of red-do , in the case of Corn, or fines which
will settle on top of the heat exchan ers and hinder the performance of the stove. This is more
likely when burnin Wood Pellets.
With the stove OFF and completely cooled down and with the aid of the Poker, tap the Heat
Exchan ers to shake loose any buildup. Insert the Poker between the Heat Exchan er Tubes to
loosen any fines that may have collected.
Keepin the Heat Exchan er area clean will assure that the efficiency of the stove will be
maintained.
