RESTRICTOR INSTALLATION
The restrictor plate included in the fireplace components packet can
be installed as either a large or small restrictor, depending on your
specific venting configuration.
There are several factors which can affect proper draft of the vent
system and the burner operation of a fireplace. Installing a restrictor
may be necessary to resolve the problem, even though it may not be
required under ‘normal conditions’.
IMPORTANT: DO NOT INSTALL IF THE VENTING
CONFIGURATION IS AT THE MINIMUM REQUIREMENTS!
The restrictor included is sized as the ‘large’ restrictor, Figure 6A.
To reduce the size to the small restrictor, simply bend the section
without the tabs off at the perforation and discard, Figure 6B.

INSTALLATION OF THE #700 SERIES HORIZONTAL DIRECT VENT TERMINATION KIT(S).
NOTE: #700 Series vent kits must be supported every 3 ft. to maintain proper rise. The flex pipe is permanently attached to
the exterior wall plate. Do not attach the #745 or #718 termination kit to the fireplace (or extension kit) until it has passed
through the wall. The termination plates should all be installed on the exterior of the outside wall.
1. If your chimney termination is 8' or less from the
stove top and doesn’t require an extension kit,
proceed to step #7.
2. If your chimney termination will require one or more
extension kits (part #746), proceed with the
following steps. Each #746 extension kit contains
enough 4" & 7" flexible aluminum pipe to extend the
chimney an additional 6'.
3. Gently stretch the 4" & 7" flexible aluminum pipes on
the termination kit (#745 or #718) and on each
extension kit, if used, the length required so when all
thesections areconnectedtogether, the ventsystem
length for your venting configuration is attained.
4. Using your extension kit pieces, place a bead of
sealant outside the 4" flex pipe collar (C) - the end
without the lip- and slide it inside the 4" pipe on top
of the fireplace (D). Secure with 3 evenly spaced
screws.
NOTE: This connection is very difficult to
remove without damaging the collars
once installed.
5. Place a bead of sealant outside the 7" flex pipe collar
(E) - the end without the lip - and slide it inside the
7" pipe on top of the fireplace (F). Secure with 3
evenly placed screws.
6. If additional extension kits are used, repeat steps #4
and #5, placing the 4" & 7" pipes onto the previous
extension kit.
Referring to Figure 9:

outer edge of the termination kit box (A), and, from
the outside, place the exterior wall assembly through
the 9 ½ " square hole. Place screws through the
four holes (B) securing it in place.
NOTE: Attachment brackets are included with the
termination kit. These optional brackets should be
screwed, or nailed (screws not provided) onto the top
and bottom of the 9 ½ " square hole, on the exterior of
the house. The termination plates then fit between these
brackets, and using the screws provided, screw the
brackets to the termination kit box (A). Attach the vinyl
siding protector.
7a. OPTIONAL: Place insulation between the 7" pipe
and the wall studs.
7b. The flexible termination kit includes an interior
firestop assembly shown on Figure 2B, page #3,
which is installed on the inside wall (over wall
materials), around the flexible pipe. Slide the
firestop over the flex pipe with the spacer legs
toward the wall.
OPTIONAL: Apply a liberal bead of sealant
around the outside / wall side edge and place
over the 9 1/2” square opening.
7c. Secure each corner with a drywall screw.
8. Gently pull the 4" & 7" flexible aluminum down to the
top of the extension kit, or the top of the fireplace if
no extension kits were used.
9. Place a bead of sealant outside the 4" flex pipe collar

BE CHECKED FOR LEAKS!
NOTE: The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of ½ psi.
NOTE: The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during any
pressure testing of the gas line at test pressures equal to or less than 1/2 psig (3.5 kPa).
Pressure check taps for the manifold (outgoing) and inlet (incoming) pressures are located in front of the gas valve. The right
pressure tap is the manifold pressure and the left pressure tap is the incoming pressure. FOLLOW INSTRUCTIONS ON PAGE
#24 OF THIS MANUAL.

EXTERNALLY ADJUSTABLE VENTURI. FIGURES 12A - 12C.
An externally adjustable venturi has been incorporated into the millivolt board assembly for this fireplace. Follow the instructions
below for proper operation and settings.
CAUTION: THE SURFACES OF THIS FIREPLACE ARE HOT WHILE THE BURNER IS IN OPERATION. ALLOW THE FIREPLACE TO
COOL PRIOR TO ADJUSTING THE VENTURI OR USE EXTREME CAUTION AND WEAR THE APPROPRIATE
PROTECTION TO AVOID SERIOUS BURNS.
Referring to the millivolt board above, locate the adjustable venturi lever attached to
the bottom of the millivolt board.
1. The venturi has been factory set for a typical minimum venting configuration
using Natural Gas.
Natural Gas: Lever is positioned in the left notched out section of the bracket
as shown in Figure 12A. This is approximately 1/4" opened.
LP Gas: Lever is positioned in the right notched out section of the
bracket as shown in Figure 12B. This is approximately 5/8" opened.
Figure 12A
The lever may be adjusted in small increments by pulling the lever down slightly
and sliding it in either direction, placing the slots in the lever(under the millivolt
board) into the smaller notches on either side of the factory-set positions.
ADJUSTMENTS:
Placing the lever to the right will close the venturi air collar allowing less air
to be mixed with the gas in the burner tube.
Placing the lever to the left opens the venturi collar allowing more air to be
mixed with the gas in the burner tube. Figure 12B
NOTE: Eachfireplace installation isdifferent- i.e.: Ventingconfiguration, chimney systemused, etc. Adjustthe venturi
opening as necessary to achieve proper burn and appearance.
CAUTION: Do not close the shutter too far! This will cause the fireplace to burn ‘dirty’ which will result in soot
accumulation inside the glass, the firebox and possibly the logs.
