Variable Vent Restriction
Vent restriction is accomplished by sliding two
restrictor panels over the combustion air intake ports
located at the back of the firebox, just below the
logset base. See Fig 19. The panel levers will be most
accessible with removal of the logset.
The panels are set in a fully open position at the
factory. Push each lever toward the center of the
firebox to increase restriction in one inch increments,
e.g: 1 inch travel = 1/3 closed position.
Use the Vent Window diagrams in Figs. 12-13 as a
starting point to determine the best restriction
setting. The ideal restrictor setting for a particular
vent system will vary depending on the specific
installation characteristics. Once the fireplace is
operating, further restrictor adjustment may be
necessary to obtain the best performance. See the
Operation chapter of this manual for further infor-
mation.

Fireplace Installation
Optional Blower
Install the optional Blower (154967) before installing
the gas supply line. The 125 CFM heat-activated fan
unit will be located in the bottom rear of the fire-
place cabinet.
Power Requirement
The blower must be electrically grounded in accor-
dance with local codes or, in the absence of local
codes, with the current NFPA 70- National Electrical
Code or CSA C22.1-Canadian Code.
A three-prong (grounding) power supply plug is
included 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 THE PLUG.
Blower Function
The blower is controlled by a heat activated switch
(snapstat) that will ONLY function if the blower
control switch is either in the HI or LOW setting.
Once the unit has been operating for a short time
and the firebox heats, the blower will start on either
the HI or LOW speed.
Conversely, once the unit is off the blower will
continue to operate until the snapstat cools and
turns the blower off.
If the blower is not needed, place the blower
control switch in the OFF position and the snapstat
will not function.
CAUTION: Always unplug the Blower when
performing any routine service to the Acadia gas
fireplace.
Installation
1. Insert a rubber grommet at each corner of the
Base Plate as shown in Fig. 20.
2. Engage the Blower unit base with the four studs
at the rear of the fireplace cabinet floor. See Fig. 21.
3. Using the M6 nuts and 10 mm socket, attach the
Control Switch / Snapstat Bracket to the two
studs protruding from the firebox floor. See Fig.
22. Be sure that the snapstat disc firmly contacts
the bracket surface.
4. Run the power cord through the opening in the
side of the cabinet nearest the receptacle. Gather
slack cord into the side cavity, away from the
plumbing and other wiring.
