Pre-installation Questions and Answers
Operations and Maintenance Instructions
Be sure to read and understand all the instructions in this manual before operation of appliance.
Ensure all wiring is correct and properly enclosed to prevent possible shock.
Check for gas leaks.
Make sure the glass door is properly installed before operation. Never operate the appliance with the glass door
removed.
Make sure venting and termination cap are installed and unobstructed.
If brick or porcelain liners are used, ensure they are installed.
Verify that the pilot can be seen when lighting the appliance. If not, the log or rock placement is incorrect.
If the unit is turned off, you must wait a minimum of 60 seconds before re-lighting it.
Venting systems should be periodically examined by a qualified agency.
The flow of combustion and ventilation air must not be obstructed.
The Burner/Log Assembly has been engineered and permanently adjusted for proper flame control.
Periodically remove the logs from the grate assembly and vacuum any loose particles from the grate and burner
areas. See Log Placement page to remove logs. Vacuum burner parts and replace logs.
Never use your gas fireplace as a cooking device.
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper a nd dangerous
operation. Verify proper operation after servicing.
About curing of the paint
Your stove or fireplace has been painted with the highest quality silicone stove paint. This paint dries quickly in 15-20
minutes when first applied at the factory. However, due to the high temperature silicone components, the paint will cure
when heat is applied to the appliance as it is first used. The following information applies to the curing process to get the
paint fully hard and durable.
Fire the appliance four successive times for 10 minutes each firing and a 5 minute cool down between each. Be aware
during log and firebox paint curing that a white deposit may be developing on the inside of the glass doors. It is important
to remove this white deposit from the glass doors using a fireplace glass cleaner.
Babies, small children, pregnant women and pets should leave the area during the cure phase.
Ventilate well, open doors and windows.
Do not touch during curing.
Why does my fireplace or stove give off odour?
It is normal for your fireplace to give off some odor at first. This is due to the curing of the paint, adhesives, silicones and
any undetected oil from the manufacturing process as well as the finishing materials used with the installations (e.g.
marble, tile and the adhesives used to adhere this product to the walls can react with heat and cause odours).
It is recommended that you burn your gas fireplace or stove for a minimum of four hours at a time with the fan off (if a fan
is present) after the curing of the paint has been completed. These odours can last upward to 40 hours of burn time; keep
burning at a minimum of four hours per use until odours dissipate.
Noise coming from the fireplace?
Noise is caused by the expansion and contraction of metal as the appliance heats up and cools down. This is normal and
is similar to the sounds produced by a furnace or heating duct. This noise does not affect the operation or longevity of
your fireplace.
It is also normal for the fan to make some noise when it comes on. This noise can be reduced somewhat by turning down
the speed of the fan with the variable speed control. Be aware, however, that this will reduce the volume of heated air
circulated into the room by the fan.
Note to the Installer:
Be sure appliance is working properly and its operation (including remote control operation, if included) is fully explained
to and understood by the customer.
For safe installation and operation note the following:

Mobile Home/Manufactured Housing Installation
Warning: Do not compromise the structural integrity of the manufactured home wall, floor
or ceiling, during installation of appliance or venting.

MQVL48 / MQVLB48 Framing Your Gas Fireplace
This section is intended for qualified installers only. Before beginning, make note of where the gas and electrical accesses
Specifications
1. Cold climate installation recommendation: When installing this fireplace against non-insulated exterior wall or chase, it
is recommended that the outer walls be insulated to conform to applicable insulation codes. Drywall & vapor barrier
must be installed over insulation to prevent contact of insulation and unit.
2. Choose fireplace location and frame in accordance with the fireplace framing dimensions specified (view diagrams).
3. Drywall or other combustible material can extend up to the Drywall Stops located on the sides of the unit, and up to
the bottom and top.
4. A Hearth is not required for this unit.
Certified for installation in a bedroom or bedsitting room. In Canada must be installed with listed millivolt thermostat (Not
permitted for decorative vented gas fireplaces installed in the U.S.A.). In USA see local codes.
Stand-off and Nailing Tab Locations
Make note of where the stand-off locations are. These stand-offs are provided as indicators to illustrate the boundaries
for framing. Therefore, no framing material is permitted to extend beyond these stand-offs.
Vertical Venting in Cold Climates
In cold climate conditions where temperatures go below -10 degrees Celsius or 14 degrees Fahrenheit, we recommend
that the chase be insulated and where the vent pipe enters into the attic space that the pipe be wrapped with an
insulated Mylar sleeve. This will increase the temperature of the vent and help the appliance to vent properly in cold
weather conditions.
It is also important in vertical vented direct vent appliances that the appliance be operated daily during the winter months
as this will help stop the termination from freezing up. We recommend using a thermostat (Not permitted for decorative
vented gas fireplaces installed in the U.S.A.) set at room temperature to allow the unit to cycle.
For IPI models it may be necessary to set the appliance to Standing Pilot mode to maintain heat in the cavity. The
purpose of this procedure is to prevent cold air from penetrating the chimney and then onto the living space. Therefore,
when the internal temperature is slightly elevated the fireplace is able to freely exhaust its combustion and hence making
it easier to startup.
Holes are provided in bottom of unit to
secure appliance to floor after installation.

are located on the unit. This will streamline the construction process. Furthermore, familiarize yourself with the venting
and clearance requirements (see Venting section) for this appliance. Failure to comply with those requirements can
seriously compromise the safety and operation of the fireplace.

MQVL48 / MQVLB48 VENTED CHASE REQUIREMENTS
FIREPLACE CHASE MUST BE VENTED AT TOP AND BOTTOM- Minimum 151 square inches free air opening at the
top of the chase, and minimum 84 square inches free air opening at the bottom of the chase.
