aiR shutteR
The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in Figure
4.
The air shutter allows the amount of air coming into the replace to be adjusted in order to accommodate
dierent climates and venting arrangements. Start the pilot and then the burner. Make sure the pilot ame
is burning normally and none of the burner ports are plugged. Let the replace burn for roughly fteen (15)
minutes and then examine the ames, compare the ames to Figure 73.
Figure 4: Gas Valve In Place on Unit
The ideal ame will be blue at the base and light
orange above. The ames should be of medium height.
If the ames look like this, no venturi adjustment is
needed. If the ames are fairly short and mostly blue,
the replace is getting too much air. Therefore, the
air shutter should be closed slightly until the correct
ames are achieved. Flames that are very orange,
with tall, dark, stringy tips, are not getting enough
air. Open the venturi until the ames clean up. If the
venturi is opened, or closed all the way, and the correct
ames cannot be attained, turn o the gas and contact
the dealer.
Warning: Incorrect venturi adjustment may lead
to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the
venturi adjustment.

During a cold start up, condensation will sometimes form on the glass. This is a normal condition with all
replaces. However, this condensation can allow dust and lint to cling to the glass surface. Initial paint curing
of the appliance can leave a slight lm behind the glass, a temporary problem. The glass will need cleaning
about two weeks after installation. Use a mild glass cleaner and a soft cloth; abrasive cleaners will
damage the glass and plated surfaces. Depending on the amount of use, the glass should require
cleaning no more than two or three times a season. Do not clean the glass when it is hot.

PLanning youR instaLLation
When planning your installation, it will be necessary to select the proper length of vent pipe for your
particular requirements. It is important to note when passing through a wall, the maximum allowable wall
thickness is 10 inches (25.4 cm), 1½ inches (3.8 cm) clearance to combustibles must be maintained. Select
the amount of vertical rise desired for “vertical-to-horizontal” type installations. To determine the length of
vent pipe required for vertical installations, measure the distance from the appliance ue outlet to the ceiling,
the ceiling thickness, the vertical rise through the attic or second story, and allow for sucient vent height
above the roof line. For two story applications, a re stop is required at each oor level. If an oset is needed
in the attic, additional pipe and elbows will be required. To connect the venting system to the appliance ue
outlet, a twist-lock adapter is built into the appliance at the factory. Refer to section “Vent Congurations” on
page 25 for venting parameters.
PRePaRation FoR instaLLation
• Remove the packaging from the appliance, and check to make sure there is no damage. If damage is
found, please report it to both the carrier and your dealer as soon as possible.
• Before beginning, carefully check the glass door and the log set
• Locate a position where the ue system of the stove can be properly installed without damaging the
integrity of the building; e.g. cutting a wall or ceiling joist.
• Check stove and ue system clearance requirements.
• Locate the stove where it can be accessed by a gas supply line.
• Locate the stove in a large and open room that is centrally located in the house. This will optimize heat
circulation and comfort.
• As the stove can be equipped with a convection fan, ensure that an electrical outlet is within 6 ft (1.8 m)
of the stove.
• The ow of combustion and ventilation air must not be obstructed.

The ENVIRO CUBE has been designed with a built in restrictor plate. The restrictor is designed to enhance
ame appearance when installing this unit with vertical chimneys as well as installations with longer horizontal
vent applications. It does this by controlling the amount of air moving through the vent pipe.
Figure 34 shows the vent restrictor position required, relative to the length of vent pipe. Longer vertical vent
lengths necessitate greater restriction; position 1 (Figure 36) is open and position 5 (Figure 37) is maximum
restriction. To avoid injury, it is best to make this adjustment when the replace is cool or use welder’s gloves
or oven mitts.
To access vent restrictor remove the valve cover plate from the right rear corner of the unit by undoing the
four fastening screws. Refer to Figure 35.
Loosen the ¼” hex head screw and adjust to the correct setting.
Slide the hex head screw to the next setting and re-tighten the screw to secure in place.
The numbers in this chart represent the actual vent restrictor settings. Although the numbers do not appear

1. Set the appliance in the desired location. Check to determine if wall studs or roof rafters are in the way
when the venting system is attached. If this is the case, you may want to adjust the location of the
appliance.
2. Direct vent pipe and ttings are designed with special twist-lock connections. Assemble the desired
combination of black pipe and elbows to the appliance adapter with pipe seams oriented towards the wall
or oor, as much out of view as possible.
Note: Horizontal runs of vent pipe must be supported every 36” (915mm). Wall straps are available for this
purpose, also when running horizontal pipe minimum clearances to combustibles must be maintained; 2”
(51mm) at top, 1½” (38mm) at sides, 1½” (38mm) at bottom.
3. With the pipe attached to the stove in the correct location, mark the wall for a 10” (25.4cm) x 10” (25.4
cm) square hole (refer to Figure 38). The center of the square hole should match the center line of the
horizontal pipe. Cut and frame the 10” (25.4cm) x 10” (25.4cm) hole in the exterior wall where the vent
will be terminated. Refer to Figure 32 and Table 3 for allowable locations. If the wall being penetrated is
constructed of non-combustible material i.e. masonry or concrete, a 7” (17.8cm) hole is acceptable.
4. Position the horizontal vent termination in the center of the 10” (25.4cm) x 10” (25.4cm) hole, and

(b) For buildings with vinyl siding, a vinyl siding stando, should be installed between the vent cap and the
exterior wall (see Figure 40). Attach the vinyl siding stando to the horizontal termination. The vinyl siding
stando prevents excessive heat from possibly melting the vinyl siding material. Note that the horizontal vent
termination bolts onto the at portion of the vinyl siding stando (shaded area in Figure 40), so that an air
space will exist between the wall and the vent termination.
(c) The horizontal run of vent pipe must be level and should have a ¼ inch rise for every one foot of
run towards the termination. Never allow the vent to run downward. This could cause high temperature
and may present the possibility of a re.
(d) The location of the horizontal vent termination on the exterior wall must not be easily blocked or
obstructed. Refer to section “Vent Congurations” on page 25.

NOTES:
(a)
If an oset is necessary in the attic to avoid obstructions, it is important to support the vent pipe every 3
feet (91 cm), to avoid excessive stress on the elbows, and possible separation. Wall straps are available
for this purpose (see Figure 45).
(b) When ever possible, use 45° degree elbows instead of 90° degree elbows. The 45° degree elbow oers
less restriction to the ow of ue gases and intake air.
(c)
For multi story installations. A ceiling restop is required at the second oor, and any subsequent oors
(see Figure 46). The opening should be framed to 10” (25.4 cm) x 10” (25.4 cm) inside dimensions, in
the same manner as shown in Figure 42.
(d) Any occupied areas above the rst oor, including closets and storage spaces, which the vertical vent
passes through, must be enclosed. The enclosure may be framed and sheet rocked with standard
building materials. However consult the appliance manufactures installation instructions for the minimum
allowable clearance between the outside of the vent pipe, and the combustible surfaces of the enclosure.
Do not ll any required air spaces with insulation.

GENERAL VENTING INFORMATION:
Canadian Installations
The venting system must be installed in accordance with the current CSA B149.1 installation code and/or
local codes having jurisdiction.
U.S.A. Installations
The venting system must be installed in accordance with the current National Fuel Gas Code, ANSI Z223.1/
NFPA 54, and/or local codes having jurisdiction. It is strongly recommended to install an approved chimney
liner in an existing brick chimney. This will maximize the potential draft of the chimney and lessen the eects
of slow chimney start-up.

VENTING OF A FIREPLACE FITTED WITH THE DRAFTHOOD ADAPTOR:
Note: Please refer to the chimney manufacturer’s installation instructions prior to commencing the installation.
This unit may be vented to an existing masonry chimney, or where no masonry chimney is available, an
approved “B-vent” chimney, or any other approved constructed chimney/vent system (see Figure 52 & 53).
In either case, the replace may be connected to the chimney/vent using a 4” (10 cm) single wall vent
connector.
When an existing masonry chimney is utilized for the venting, we recommend the vent connector be connected
to an approved 4” (10 cm) diameter ue liner running the full height of
the chimney. In many jurisdictions this ue liner may be mandatory.
If 4” (10 cm) single wall vent is used, a minimum of 6” (15 cm) must be
maintained between the vent connector and any combustibles.
If 4” (10 cm) “B-vent” is used a minimum of 1” (25 mm) must be
maintained between the vent connector and any combustibles.
CAUTION: A minimum vent height of 12’ (3.6 m) from the oor is
required to eectively vent this replace.
SPILLAGE TEST:
A spillage test must be performed prior to leaving the installed replace
with the customer. Perform this test in the following manner:
1. Close all windows and doors in the room.
2. Start all exhaust fans in the house and the furnace blower.
3. Light the replace and set to maximum ame adjustment.
Initial Installation
QUALIFIED INSTALLERS ONLY
Figure 61: Draft test place.
4. After a minimum of 10 minutes operation,
test the chimney draft with a smoke
match at the top row of the pattern to
conrm that there is adequate draft or
‘pull’ at the openings around the body
of the Drafthood Adaptor, as shown in
Figure 54.

AUTOMATIC SAFETY SHUT DOWN:
If the spill switch is activated and shuts o the main burner the following procedure should be followed.
• Is the pilot ame still on? If not, the reason for the replace shut down is not the spill switch.
• Turn o the pilot ame and turn o all controls. Let replace to cool down.
• Check for blockages or restrictions in the ue and venting components.
• Restart the replace and check for vent draft as described earlier.
• Operate the replace in a normal manner.
• If the main burner shuts down again after a period of operation, turn o the replace and contact your
service technician.

SPILL SWITCH REPLACEMENT:
Use the following instructions to replace the Safety
Spill Switch.
1. Turn the unit o and allow it to cool.
2. Disconnect the spill switch wires from the IFC
(see Figures 50 & 51).
3. Remove the four mounting screws holding the
spill switch bracket and remove the bracket (see
Figure 55).
4. Remove and replace the spill switch with a 50-
885 Spill Switch Assembly using a T-20 torx type
driver.
5. Follow the reverse of the previous steps.
OPTIONAL FINISHING:
In installations where the ue connector is running from the drafthood into a non-combustible chimney the
following optional nishing technique can be used.
CAUTION: Installations where the ue connector or venting connects to, or passes through,
combustible walls or ceilings, the inner vent components must be ‘B-vent’. It is not allowable
in these applications to use single wall inner vent components.
For decorative purposes a 6” (15 cm) single wall black stove pipe may be installed over the 4” (10 cm) single
wall or ‘B-Vent’.
Note: The use of these components is for aesthetic purposes only and does not eect the fact
that the replace, when tted with the Drafthood Adaptor, is a Natural Vent appliance and
therefore draws air in through the Drafthood Adaptor intake ports.
