2. DIMENSIONS AND CLEARANCES TO COMBUSTIBLES
FIREPLACE INSERT: The stove can only be installed in a solid fuel burning fireplace .
Mantle pillar to stove 10”
Stove top to 8” wide mantle 12”
Minimum firebox size W 26” x H 20” x D 20”
(NOTE; standard size shown – optional 33”H x 46”W available)
FREESTANDING:
Side wall to stove 10"
Rear wall to stove 4"
Combustible to stove Top 22"
Floor to stove 0"
Corner clearance 2"
Alcove depth 48"
Maintain sufficient clearances for service and maintenance
FIREPLACE INSERT / WITH ZERO CLEARANCE KIT ( Part # 828- 134 )
After deciding where to locate the fireplace insert you must frame an opening to except the Zero Clearance Box to reduce the clearance to
combustibles. The framing dimensions are as follows; 32 1/4” wide, 29 3/8” high and a depth of 14 3/4”.
The header at the top front of the opening must be a 2x4 on edge or a cut out in the 2x4 to maintain clearances to combustibles to the vent
pipe. A minimum of 1 1/2” clearance must be maintained to the vent pipe.
Before you install the Zero
Clearance Box you must
determine the finished hearth
height.(including tiles, subfloor, etc.)
The bottom of the box must be the
same height as the finished
hearth height.

ZERO CLEARANCE BOX ASSEMBLY;
First take the kit from the box and place the surround panels aside so as not to damage the panels. There will also be a bag of screws, nuts
and bolts in the box. The bottom section of the kit will have two 3 inch square boxes mounted to the bottom. First attach the bottom to the
back with the screws provided, the hole should be located in the
lower right hand corner looking at it from the front. The side can then
be mounted to the bottom panel and the back panel. There are three
(3) vee shaped standoffs with six screw holes in each, and they
should be mounted on both sides as well as the back. There are also
two (2) triangular support brackets that must be fastened to the inside
of the box. There is a right hand and a left hand bracket, they should
be mounted with the flanges pointing upwards.
There are two long “L” shaped framing brackets that are screwed in
from the outside front edge of each side. Each bracket has three
adjustment holes depending on the thickness of the finished wall. The
hole that is furthest forward are for a wall thickness of 1/2” drywall
and the other holes are for other wall thickness up to 7/8” thick. The
Zero Clearance kit must be flush with the finished wall.
The next step is to put the top on the box. It will fit inside of the back
and side panels and is screwed in from the outside. The two short
vee shaped standoffs are screwed on to the top of the zero clearance kit. There are two large “L” type brackets that are to be screwed
down on either side of the hole were the flue pipe exits the box. These two brackets are to locate the clamping bracket that holds the
Simpson Duravent Telescoping pipe and allows the 828 unit to be disconnected and
removed if the unit needs to be repaired.
The next step is to attach the top extension to the Zero Clearance box. This is screwed
to the top front edge. The top framing bracket is in turn screwed to the top extension.
This top framing bracket has the same adjustment settings as the side framing
brackets.
Once the Zero Clearance box has been assembled it can be attached to the wall.
Place the unit into the framed opening and make sure the box is plumb and level.
The gas line then should be run through one of the three holes provided. The electrical
cord and conduit (if a fan is to be installed) should also be run into the box at this time.
The electrical box that is supplied with the fan kit will be mounted on the side, there
are two holes inside the Zero Clearance box for mounting.
The venting is the next step of installation. The pipe support on the top of the Zero
Clearance kit is made to hold the telescoping pipe section. The clamp should be
fastened 2” down from the top of the male end of the pipe.
This will allow the top of the pipe to be held in place while
the bottom section of pipe is attached to the stove.
The wall can now be finished with drywall and mantel if so
desired.
Installing the 828 direct vent insert. The unit can be lifted
up and put on the two support boxes on the bottom of the
box and then pushed back into the box. There are two
holes that must line up from the triangular supports inside
the Zero Clearance box to the holes on the inserts side
panel brackets and attached with the two screws provided.
The vent pipe should then be connected to the top of the
fireplace as well as the gas and electrical connections. The
vented skirt can now be mounted to the bottom of the unit
with the two 10 x 24 hex head screws provided, inserted
into. The surround panel can now be assembled and
bolted to the front of the stove.

3. DECIDING WHERE TO LOCATE YOUR STOVE
FREESTANDING:
• Locate the stove in a large and open room that is
centrally located in the house. This will optimize heat
circulation and comfort.
• The stove should be located out of traffic, away from
furniture and draperies and should have sufficient
access for its safe operation and maintenance.
• The flow of convection air can not be blocked
• The stove can be installed on any combustible flat
surface providing that it is installed on a metal or wood
panel extending the full width and depth of the
appliance.
FIREPLACE INSERT
• The fireplace insert model can only be located in an existing wood burning steel or masonry fireplace. The existing chimney
must be lined using a Simpson Dura Vent sealed co-linear vent system using the Envirogas kit 828-135 (DV insert / co-linear
adapter).
• Check the stove and flue system clearance
requirements. Locate a position where the flue system
of the stove can be properly installed without damaging
the integrity of the building. e.g. cutting through a wall or
ceiling joist.
• Locate the stove where it can be accessed by a gas
supply line.
• Note: If the stove is equipped with the optional
convection fan, the electrical cord is only 8 ft. (2.4 m)
long.
