Recommendations for Finishing of Clean View Linear Products
When finishing the wall around the fireplace, it is critical that the wall covering be fastened properly. It is acceptable to
pre-drill holes and use self-tapping screws which may be used to fasten a backer for tile, marble, etc. Screws being
installed through non-combustible board should be self-tapping type with a maximum length of 2 inches. Wall covering
fasteners, such as screws or nails, are not permitted in some locations. Do not drill or install longer screws which may
penetrate into the lower cover panel area as this may damage internal components.
Only non-combustible materials may be used over the face of the appliance.
We recommend that DUROCK (non-combustible material) be tied in to the entire perimeter of the fireplace for durability.
Finishing Recommendations (Obtained from professional construction contractors and finishers):
Frame unit with metal studs (minimum 20 gauge).
Minimum of 1/2” DUROCK cement board (this non-combustible panel is ULC listed as a wall shield/floor protector) and
fasten to the entire perimeter framing.
Use fiberglass (mesh) tape for all joints in area of the fireplace.
Use Yellow joint mud (contains high amounts of glue) – two coats, finishing with one coat of green topping mud, sand
and prep for painting.
If not using a surround, a metal “L” Trim may be used to finish perimeter of DUROCK.
Refer to the following website for more information on using DUROCK Cement Board: www.cgcinc.com
OTHER NOTES:
-A full single sheet of non-combustible board (no joints) above the unit is recommended if possible.
-It is preferred to attach the non-combustible board to framing only and not directly to the unit to allow for expansion and
contraction during normal operation.
-Lighter colored painted surfaces may discolor due to heat exposure.

Pre-installation Questions and Answers
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 commercial 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 odour. 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.

MQRB4436: Framing Your Gas Fireplace
This section is intended for qualified installers only. Before beginning, make note of where the gas and electrical accesses 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.
Kingsman Flex venting MUST be used on the MQRB4436.
Use of DuraVent- DirectVent Pro or other hard pipe Venting systems is not permitted.
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.
Airbox on flue side must maintain Min. 1” Clearance from Combustible (Wood) Framing (see framing 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.When installing horizontal with a 90 degree bend, maintain a minimum of five inches [5"] above the bend with the
Wall Thimble Shield [Z57WTS] in enclosures below seventy-two inches [72”]. See MQRB4436 Combustible
Enclosure Heights page.
5.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 [In the U.S.A. Thermostats are not permitted for Vented
Gas Fireplaces (ANSI Z21.50b-Decorative)]. In USA see local codes.
Stand-off 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 [In the U.S.A. Thermostats
are not permitted for Vented Gas Fireplaces (ANSI Z21.50b-Decorative)]. 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.

MQRB4436 Mantel Clearances
Before installing any mantels it is important to determine the combustibility of its
material(s). There are two types of mantels to consider: Combustible and Non-
Combustible.
A Combustible Mantel is one that consists of material(s) that may discolor,
combust, or lose its integrity in the presence of heat. These types of mantels
must strictly conform to the dimensional requirements shown below.
Conversely, a Non-Combustible Mantel is one that is constructed with material(s)
that will not combust. Check your local codes and regulations to determine whether your mantel is Combustible or Non-Combustible.
-Combustible Objects on Non-
Combustible Mantel Warning-
Combustible objects must not be placed
on a Non-combustible Mantel unless the
mantel meets the dimensional
requirements for a Combustible Mantel.
Refer below to determine whether your
mantel conforms to the requirements of
a Combustible Mantel.
The advantage to Non-Combustible Mantels is that it may extend right up to the tile lip of the fireplace. Combustible mantels must
adhere to the dimensional restrictions shown below.

MQRB5143: Framing Your Gas Fireplace
This section is intended for qualified installers only. Before beginning, make note of where the gas and electrical accesses 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.
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.
Airbox on flue side must maintain Min. 1” Clearance from Combustible (Wood) Framing (see framing 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.When installing horizontal with a 90 degree bend, maintain a minimum of five inches [5"] above the bend with the
Wall Thimble Shield [Z57WTS] in enclosures below seventy-two inches [72”]. See MQRB5143 Combustible
Enclosure Heights page.
5.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 [In the U.S.A. Thermostats are not permitted for Vented
Gas Fireplaces (ANSI Z21.50b-Decorative)]. In USA see local codes.
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 [In the U.S.A. Thermostats
are not permitted for Vented Gas Fireplaces (ANSI Z21.50b-Decorative)]. 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.
Stand-off 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.
