OPTIONAL BLOWER INSTALLATION
INSTALLATION TO BE DONE BY A QUALIFIED INSTALLER and must be electrically connected and grounded in accordance with local codes.
In the absence of local codes, use the current CSA C22.1 CANADIAN ELECTRICAL CODE in Canada or the ANSI/NFPA 70 NATIONAL
ELECTRICAL CODE in the United States.

6. Thread the other thermodisc lead through the junction box bushing and connect to the white wire of the power cord using a nut
connector. Secure ground wire (green) to the threaded weld stud located on the junction box wall. Reposition the junction box. Verify that
the wires will not interfere with the fan.
BECAUSE THE BLOWER IS THERMALLY ACTIVATED, WHEN TURNED ON, IT WILL AUTOMATICALLY START APPROXIMATELY
15-45 MINUTES AFTER LIGHTING THE FIREPLACE. USE OF THE FAN INCREASES THE OUTPUT OF HEAT.
Drywall dust will penetrate into the blower bearings causing irreparable damage and must be prevented from coming into contact
with the blower or its compartment. Any damage resulting from this condition is not covered by the warranty policy.

CONTROLLING COMBUSTION AIR

WARNING
!
Fireplace operation does require air. Do not take air from other fuel
burning appliances which can result in improper venting (smoking)
or air dilution. Always provide adequate makeup air.
If the outside combustion air kit is not used, air may still be drawn
directly into the fi replace through the lower louvres. Outside and
inside air may be combined by pulling the outside air lever out as far
as possible, and turning the lever 90° to its locking position.
Should you fi nd a frost build up on
from the fi replace, close the outside
is not in use.

WARNING
!
1. Turn off any electrical power to the fi replace (if applicable). Open the lower louvred
control door.
2. Locate the vibration reducing pad over the two threaded studs, piercing 2 holes into
the pad. The fan must be installed on the left hand side of the fi replace entirely on the pad.
3. Slide the fan to the back of the fi replace taking care not to damage the terminals.
Position the fan onto the studs and secure using the lock washers and wing nuts provided.
Pull the leads to the front and right side of the ashpan housing.
4. Remove the junction box. Use a nut connector to attach the black wires of the variable
speed switch and the power.
5. Pass the two fan leads and one thermodisc lead through the junction box bushing.
The thermodisc is located inside the outer shell, just above the louvre door. Connect one fan
lead to the thermodisc lead and the other fan lead to the white wire of the variable speed
switch using nut connectors.

ACHIEVING PROPER DRAFT

Draft is the force which moves air from the fi replace up through the
chimney. The amount of draft in your chimney depends on the length
of the chimney, local geography, nearby obstructions and other forces.
Adjusting the draft control regulates the temperature. The draft can
be adjusted from a low burn rate with the handle at the bottom setting
to a fast burn rate with the handle at the top setting. Inadequate draft
may cause back-puffi ng into the room and may cause plugging of
the chimney. Too much draft may cause an excessive temperature
in the fi replace, glowing red fi replace parts or an uncontrollable burn
which can all lead to a chimney fi re or a permanent damage to the
unit. Do not operate your fi replace for longer than 30 minutes
with the draft control on 'HIGH' (fully
open).
