B. Flip the back of the latch down to release the glass assembly.
C. Pull the bottom the glass assembly out and lift up off the tabs at the top (A).
D. Set aside where it will not be broken.
Figure 2
C) POSITION THE FIREPLACE. See Figures 3, 4A, 4B, & 4C.
1. Determine the exact position of your fireplace, vent run and vent
termination cap location.
HORIZONTAL TERMINATIONS
IMPORTANT: The vent termination cap location must comply with
the clearances as shown on page #9. A firestop adaptor is included
with this fireplace and must be used in conjunction with the chimney
system firestop / wall thimble to ensure proper clearances are main-
tained when the chimney passes thru the wall.
VERTICAL TERMINATIONS
Refer to instructions included with the chimney system for position-
ing the chimney .
NOTE: Even though the minimum clearance from the top and sides
is 0 ", we recommend that you allow an expansion space of 1/4"
from the top & sides to prevent cracking of face materials due to
expansion of the unit during heating. If expansion room is not left,
the unit will make a loud „banging‟ noise when it heats up or cools
down.
NOTE: When the unit is installed directly on carpeting, tile, or other
combustible materials other than wood flooring, it must be installed
on a metal or wood panel extending the full width and depth of the
unit. The minimum for the support platform under the unit is 20"
deep by 36" wide. If masonry is to be used (optional), prepare the
necessary foundation for the masonry load. When masonry con-
struction is being used, a lintel must be used over the top of the unit
to support the added weight.
NOTE: A hearth is not required. If a hearth is desired, combustible materials
may be used.
CAUTION: COLD AIR TRANSFER AREA. The surrounding outside wall
must be insulated to prevent cold air from entering the room.
Provide for a minimum of 6" of clearance in front of the lower grill. This will
provide adequate space to open and operate the controls behind the lower
grill.
Do not obstruct the upper and lower grill areas to allow proper ventilation air
around the fireplace. Room air enters the convection passageway at the
lower grill, and exits out the upper grill. DO NOT BLOCK THIS PASSAGE.
NOTE: Due to high temperatures, this unit should be located out of
traffic areas and away from furniture and draperies.
SEE-THRU INSTALLATIONS:
Rough opening dimensions differ on the „front and back sides‟. The
opening on one side must be a minimum of 38" wide to allow ade-
quate room to slide the unit into position. See page #8.
NOTE: The control valve assembly may be rotated so that it is accessi-
ble from the opposite side from which it was manufactured. Refer to
page #15.
PAGE 7

HORIZONTAL TERMINATIONS:
1. Determine width & depth of the hearth (optional).
2. Determine the vent run and termination cap location. If possible, place the fireplace in such a manner that the piping will be placed between two studs
so additional framing is not necessary.
NOTE: Allow a minimum of 18" between the unit and inside wall to comply with minimum termination requirements. See pages #8-#11 for
horizontal termination guidelines.
3. Cut a hole for the wall thimble, 11 ½" high x 10 ½" wide. The top of this hole must be a minimum:
#700 Series Flexible Vent System: 46" * above the height of the optional hearth.
Rigid Pipe: 47 1/4" * above the height of the optional hearth.
* IMPORTANT: This measurement is determined by the vertical and horizontal length of the venting application desired. The measurement
is to the TOP of the pipe. Please refer to information below through page #14 of this installation manual for requirements and restrictions.
4. Rough in the wall enclosure.
SEE-THRU INSTALLATIONS:
Rough opening dimensions are: Front face - 36 ½" wide x 32 ½" high Back face - 38" wide x 32 ½" high (above the height of the optional hearth). Depth
is determined by the thickness of face materials being used. IMPORTANT! The fireplace depth is 20". See Figure 3 below.

MINATION 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.
NOTE: The #700 Series vent kits must be supported every 3 ft.
to maintain proper rise.
1. If your chimney termination is 8' or less from the stove stop and
doesn‟t require an extension kit, proceed to step #7.
2. If your chimney termination will required 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 termina-
tion kit (#745 or #718) and on each extension kit, if used, the
length required so when all the sections are connected together,
the vent system 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 fire-
place (F). Secure with 3 evenly spaced screws.
6. If additional extension kits are being used, repeat steps 3 and 4,

IMPORTANT:
REFER TO FIGURE 1B, PAGE #5 FOR PROPER GAS LINE AND ELECTRICAL WIRE INSTALLATION LOCATION.
GAS LINE POSITION: THE GAS LINE MUST BE HORIZONTALLY RUN THRU THE GAS LINE HOLE PROVIDED AT THE VENTED END OF THE FIRE-
PLACE. THE FANS WILL NOT FIT ONTO THE MOUNTING STUDS IF THE GAS LINE IS NOT RUN IN THIS MANNER. Refer to the Figure 11A, page #17.
ELECTRICAL WIRING: THE ELECTRICAL WIRING SHOULD BE DONE PRIOR TO ENCLOSING THE FIREPLACE WITH FINISH MATERIALS. RUN THE
ELECTRICAL WIRE THROUGH THE PROPER HOLE PROVIDED AT THE VENTED END OF THE FIREPLACE.
This fan kit includes a receptacle / speed control box for connection of the fan cord. Wiring for the fan & speed control should be inserted and properly
connected inside this box.
WARNING: This appliance is equipped with a three-prong (grounding) plug for protection against shock hazard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.
NOTE: CODE APPROVED LINE VOLTAGE WIRING 16 GA. OR BETTER MUST BE USED. This system, when installed, must be electrically grounded in
accordance with local codes, or in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 - Current Edition.
INSTALLATION GUIDELINES:
NOTE: THESE INSTRUCTIONS REFER TO THE FIREPLACE „FRONT‟ AND „BACK‟. THE „FRONT‟ IS DESIGNATED AS THE SIDE WHICH HAS THE GAS
CONTROL VALVE ACCESS DIRECTLY BEHIND THE LOWER GRILL (AS MANUFACTURED). THE „VENTED END‟ IS ON THE RIGHT.
Important: The mounting studs are located on the floor of the fireplace at the „vented end‟ behind the lower grills. One set of mounting studs are provided for
each fan assembly.
1. Remove the front & back lower grills by loosening and removing the nuts securing it and remove it from the hinges.
2. Install the left & right fan assemblies onto the mounting studs (A). The left fan, with the power cord and wire harness, should be installed on the „back‟
studs. Refer to the figure on page #17. Secure with the nuts provided.
3. Feed the two single black wires (B), with blue connectors, around the front of the leg, then thru the center opening of the leg and slide onto the motor
terminals on the right fan. (One end of each wire is attached to the left fan at the factory.) This will prevent the cords from coming into contact with the
fan blades.
4. Feed the gray power cord through the center opening of each leg as shown on following page.

WIRING INSTRUCTIONS:
IMPORTANT: The electrical / speed control box is mounted to the left side of the gas valve bracket and secured with (2) phillips head screws.
The electrical wiring should be sufficiently run to allow ample wire for proper connection to the electrical / speed control box once secured to
the bracket.
1. Loosen and remove the screw securing the back plate on the electrical / speed control box and remove the plate.
2. Feed the electrical wire inside the box through the hole located on the left end.
3. Connect the ground wire to the green wire inside the box. The common wire is connected to the white wire and the ‘hot’ wire is connected
to the black wire.
4. Place the black grommet, included in the components packet, around the electrical wire and snap the grommet into the hole, securing the
electrical wire.
5. Replace the back plate and secure with the screw.
6. Mount the box onto the gas valve bracket and secure with (2) phillips head screws (provided).
7. Plug the gray fan power cord into the receptacle located on the left end of the box.
8. Place the temperature control switch (C) (magnet attached) onto the bottom of the firebox. This control switch activates the fan as the fire-
place heats and its location determines how quickly the fan will turn ‘on’ and ‘off’ and may be adjusted as desired. When placed in a cooler
area, it will take longer for the fan to turn ‘on’, but will turn ‘off’ sooner after the burner has been turned ‘off’.
9. Turn the speed control counter-clockwise until you hear a ‘click’. This is the ‘OFF” position.
10. Turn the speed control ‘ON’ by turning the knob clockwise past the ‘click’ - this is the highest setting.
NOTE: The fan will not operate unless the speed control has been turned ‘ON’. The fan will not turn ‘ON’ until sufficient heat is ap-
plied to the thermostatic control switch . The fan will turn ‘ON’ and ‘OFF’ automatically when the fireplace heats and cools. Adjust
fan to desired speed while it is running.
TEMPERATURE CONTROL SWITCH POSITION: Prior to adjusting the temperature control switch, unplug the 3-prong plug on the
fan cord from the receptacle. Adjust the position of the temperature control switch to a warmer location under the firebox to turn the
fan ‘ON’ sooner or move it to a cooler location under the firebox to turn the fan ‘ON’ later. The fan will turn on when the sensor in the
temperature control switch reaches 110oF and will turn ‘OFF’ when the sensors reach 90oF. After adjustment, plug the 3-prong plug
on the fan cord into the receptacle.
