!
WARNING
IT IS IMPORTANT TO SELECT AND USE ONLY PELLETS THAT ARE DRY AND FREE OF DIRT OR ANY
IMPURITIES SUCH AS HIGH SALT CONTENT. DIRTY FUEL WILL ADVERSELY AFFECT THE OPERA-
TION AND PERFORMANCE OF THE APPLIANCE AND WILL VOID THE WARRANTY. THE PELLET
FUEL INSTITUTE (P.F.I.) HAS ESTABLISHED STANDARDS FOR WOOD PELLET MANUFACTURERS.
WE RECOMMEND THE USE OF PELLETS THAT MEET OR EXCEED THESE STANDARDS. ASK YOUR

HIGH LIMIT SWITCH: Your appliance is equipped with a high limit switch. In the event that the temperature of
the appliance approaches an unsafe operating temperature, this switch will shut down the pellet feed, which
will eventually shut down the unit. If this happens, it is important to find out why the unit overheated. Contact
your local dealer.
LOW LIMIT SWITCH: This switch will automatically shut down the appliance if the fire goes out or fails to light
within 15 minutes.
HOPPER DOOR INTERLOCK: Your appliance is equipped with a micro switch in the hopper assembly that
shuts-off the auger when the hopper door is opened. Closing the door switches the auger back on, allowing
pellets to feed again.
VACUUM SWITCH: This switch will sense lack of air flow through the appliance and shut down the pellet feed.
This lack of flow could be caused by a blocked vent.
POWER FAILURE: In the event of a power failure, the appliance will shut down. Once power is restored, the
appliance will re-start, unless the convection air temperature has gone above the high limit switch setting. If
this happens, contact your local dealer.

3.0 INSTALLATION PLANNING
Check with local building officials for any permits required for installation of this pellet appliance and notify your
insurance company before proceeding with installation.
Before installing we recommend placing the appliance outside and load 5 pounds of pellets inside the hopper.
Plug the appliance in and let it run on HIGH until the pellets run out. This will cure the paint and burn off most
of the oils on the steel, thereby minimizing any smell inside the home. 68.1
READ ENTIRE MANUAL BEFORE YOU INSTALL OR USE THIS APPLIANCE. FAILURE TO FOLLOW THE
INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY OR EVEN DEATH.
USE ONLY WOLF STEEL APPROVED OPTIONAL ACCESSORIES AND REPLACEMENT PARTS WITH
THIS APPLIANCE. USING NON-LISTED ACCESSORIES AND REPLACEMENT PARTS (BLOWERS,
DOORS, LOUVRES, TRIMS, GAS COMPONENTS, VENT COMPONENTS, ETC.) COULD RESULT IN A
SAFETY HAZARD AND WILL VOID THE LIMITED LIFETIME WARRANTY.

With K values, the lower value is a better insulator. With R values, the highest number is better.
K-Value Example:
A wood stove may call for thermal protection which has a K factor of 1 or less. A product
such as Micore 300 Board from USG has a K-Value of approximately .43 per inch.
Therefore, a 1/2” thickness of this board would have a K-Value of .86, which meets the
requirement of our example stove.
R-Value Example:
A stove or fireplace may call for thermal protection with an R-Value of 1.5. This same
board above is rated as having an R-Value of 2.33 for a 1” thickness. Therefore, 3/4” of
the Micore 300 Board would meet the specifications for this stove.

29.4A
Installation into a manufactured home or mobile home should be installed in
accordance with the Manufactured Home Construction and Safety Standard,
Title 24 CFR, Part 3280, in the United States or the Mobile Home Standard,
CAN/CSA Z240 MH Series, in Canada.
The appliance must be grounded to the steel chassis of the mobile home
(Some states do not require this; check with your local building department).
!
WARNING
DO NOT INSTALL IN A SLEEPING ROOM.
THE STRUCTURAL INTEGRITY OF THE MANUFACTURED HOME FLOOR, WALL, AND CEILING ROOF
MUST BE MAINTAINED.
3.5 OUTSIDE AIR
Available from yourAuthorized Dealer (114KT)
Outside air must not be drawn from an enclosed space (garage, unventilated crawl space).
NOTE: Wolf Steel Ltd. strongly suggests using outside air for all residential installations, especially for
those that are energy efficient, air-tight homes.
Outside air supply must not be over 15' long.
Outside air vents must be made with 1 3/4" diameter or larger metal or aluminum duct with a metal screen at-
tached to the end to keep out rodents (P.V.C. or other materials may not be used).
The outside air inlet must not be above or within 12" of the chimney termination, must have a rain cap or down-
turned elbow to prevent the water from entering and be located so that it will not become plugged by snow or
other material.
Outside air is required for all combustible built-in enclosure installations.

4.0 VENTING
4.1 TYPE OF VENT
4.2 INSTALLING THE PELLET VENT
4.3 VENTING THE PELLET APPLIANCE
Must be an approved 3" or 4" diameter Type "L" or "PL" vent, vented to the outside or connect the vent to a
factory built type "A" chimney using an adaptor; and/or stainless steel chimney liner for masonry appliance in-
stallations. Use 4" diameter vent if vent or liner height is over 15' or if installation is over 4,000' above sea level.
Use an approved wall thimble when passing the vent through walls and a ceiling support / firestop spacer when
passing the vent through ceilings (maintain a 3" clearance to any combustibles).
7.5C
The vent must have a support bracket every 5’ when on
the exterior wall. To achieve optimum performance, keep
vent runs as short as possible, especially on horizontal
installations.
MAXIMUM VENTING: Maximum venting height is 33’.
Maximum horizontal without vertical rise is 5’ straight
off the back of the appliance. Use no more than 180° of
elbows (two 90° elbows, or two 45° elbows and one 90°
elbow, etc), excluding the tee and the termination.
VENT INSTALLATION: Termination must exhaust above
the air inlet elevation, and parallel or above the exhaust
output of the pellet appliance. It is recommended that at
least 3’ of vertical pipe be installed to create some natural
draft. This is to help prevent the possibility of smoke or
odour entering the home during the appliance shut down
or in the event of a power outage. Horizontal sections
must have a 1/4” rise every 12” of travel if longer than 3’.
The pellet vent connections must be sealed with HI-Temp
RTV Silicone and screwed together with at least 3 3/8”
long stainless steel screws. Seal each vent section by
injecting a liberal amount of 500°F (260°C) RTV silicone
sealant into the gap. We recommend sealing the outside
of the vent connections to permit easier access when
servicing.

4.4 PELLET VENT TERMINATION
The vent termination must have an approved cap (to prevent water from entering) or a 45° downturn.
If the termination is located on a windy side of the house, a shield is recommended to prevent soot from build-
ing up on the side of the house.
Horizontal terminations must protrude 12" from the wall, vertical terminations require a minimum 24" above the
highest point that it penetrates through the roof.
Depending on pellet quality, vent configuration and air settings, black soot may occur on the terminal wall.
