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 CONCRETE BOARD (non- combustible material) be tied in to the entire perimeter of the fireplace for durability.
Notice: Granite, tile, or other facing materials are not covered by the fireplace
warranty. Natural stone, tile, and other facing materials may crack or discolor (i.e., yellowing
of lighter colored materials). Televisions are not covered
by fireplace warranty.
Finishing Recommendations (Obtained from professional construction contractors and finishers): Frame unit with metal studs (minimum 20 gauge).Wooden studs may be used, but may cause drywall screws to pop
or pull due to wood studs drying out. Minimum of 1/2″ CONCRETE BOARD 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 CONCRETE BOARD. Refer to the following website for more information on using CONCRETE BOARD 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 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 odor? 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 odors).
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 odors can last upward to 40 hours of burn time; keep burning at a minimum of four hours per use until odors 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.
Operations and Maintenance Instructions
For safe installation and operation note the following:
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 and dangerous
operation. Verify proper operation after servicing. Areas in and around the Chase Vent Openings should be cleaned annually.

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.
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 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.
Certified for installation in a bedroom or bedsitting room. In Canada must be installed with listed millivolt thermostat. 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.

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.
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 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.
Certified for installation in a bedroom or bedsitting room. In Canada must be installed with listed millivolt. 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.

Door and Glass Information
Glass Cleaning It will be necessary to clean the glass periodically. During startup, condensation, which is normal, forms on the inside of the glass, and causes dust, lint etc. to cling to the glass surface. Also, initial paint curing can deposit a slight film on the glass. It is therefore recommended that initially the glass be cleaned two or three times with a commercial fireplace glass cleaner. After that, the glass should be cleaned two or three times a season depending on the circumstances.
Cautions and Warnings
Do not clean when the glass is hot.
The use of substitute glass will void all product warranties (see Glass Replacement in this section). Care must be taken to avoid breakage of the glass.
Do not operate this fireplace without the glass front or with a broken glass front.
Do not strike or abuse the glass.
Glass Replacement Only Robax ceramic or coated Neoceram glass may be used for replacement for Models MQRB4436, MQRB5143 and MQRB6169. Glass must be minimum 5mm thick. To replace glass, clean all materials from the door frame. Scrape off old silicone all the way down to the metal. Using high-temp silicone [rated up to 500°F (260°C)] apply a continuous bead of approximately 1/8″-3/16″ to all four [4] sides of the frame. With the frame resting on a flat surface, insert the new glass with a new gasket. Gently press the glass into the silicone. Be careful not to use excessive force on the glass. Let the silicone dry for approximately 15-20minutes.
Use caution when removing broken glass. Wear gloves.
Removal of the Glass Door NOTE: A Door Latch Tool is provided to assist with removing and installing the glass doors. See next page. 1. Remove the door by unlatching the 2 top latches. Simply place 2 fingers in the grooves, and pull and lift upward slightly. 2. Once the top of the door is unlatched, tilt the door forward and lift upward to release the bottom. 3. When re-installing the door, place the bottom of the door into the door retainer slot and then secure the door with the top latches.
Spring Replacement *Over time, the door latch spring (Part#36HB-123) may need to be replaced if tension is lost.
1. To replace latch spring, remove the 2 hex screws (located in the firebox) that secure the latch assembly in place. 2. Once the screws are removed the latches will slide out of place. 3. Remove the locknut from the latch assembly and replace the spring. Re-tighten the locknut until 2 thread turns are beyond the
locknut. This is critical for proper tension. Replace latch assembly.

Troubleshooting the Gas Control System

WARNING
BEFORE DOING ANY GAS CONTROL SERVICE WORK, REMOVE THE GLASS FRONT. NOTE: Before troubleshooting the gas control system, be sure external gas shut off is in the “On” position.

Problem
Spark igniter will not light.

Possible Causes
Defective or misaligned electrode at pilot.
Defective igniter (pushbutton).

Pilot will not stay lit after carefully following lighting instructions.

Defective thermocouple (flame switch where applicable).

Pilot burning, no gas to burner, valve knob “ON”, and wall switch “ON”.

Defective valve magnet.
Wall switch or wires defective.

Generator may not be generating sufficient voltage.

Plugged burner orifice.
Defective automatic valve operator.

Frequent pilot outage problem.
Flame lifts off burner and goes out in less than 30 seconds.
Flame lifts off burner on one side while the rest of the flame remains lit.

Pilot flame may be too low or blowing (high) causing the pilot safety to drop out.
Inner 4″ liner has come off flue or termination, flame is starving for oxygen.
Improper installation of firebrick. Firebrick is likely leaning.

Corrective Action
Check for spark at electrode and pilot: if no spark and electrode wire is properly connected, replace igniter.
Using a match, light pilot. If pilot lights, turn off pilot and push the red button again. If pilot will not light – check gap at electrode and pilot should be 1/8″ to 1/4″ to have a strong spark.
Check pilot flame. Must impinge on generator and thermocouple. Clean and/or adjust pilot for maximum flame impingement on generator and thermocouple. Replace thermocouple if pilot will not hold. (Hand tight 1/8 turn on replacement)
Replace valve, if pilot won’t hold after the thermocouple is replaced.
Check wall switch and wires for proper connections. Jumper wire across terminals at wall switch. If burner comes on, replace defective wall switch. If okay, jumper wires, across wall switch wires at valve. If burner comes on, wires are faulty or connections are bad.
Check generator with millivolt meter. Take reading at generator terminals of gas valve. Should read 325 millivolts minimum while holding valve knob depressed in pilot position and wall switch “off” Replace faulty generator if reading is below specified minimum.
Check burner orifice for stoppage and remove.
Remove wall switch wires from gas valve. Install jumper wires from top bottom terminals of gas valve. Turn valve on “ON”. If main burner does not light, replace valve.
Clean and/or adjust pilot flame for maximum flame impingement on generator and thermocouple. *See NOTE below ­ Seven Day Timer
Attach 4″ liner to flue or termination using screws, silicone and clamps as stated in manual.
Be sure to position firebrick against firebox walls and be sure to use brick clips attached to the inner side of firebox.

*NOTE: The pilot system for this appliance may be equipped with a Seven Day Timer, in which case the pilot flame will be extinguished if the main burner has not been turned ON for seven days.
This Seven Day Cycle is reset every time the main burner is cycled ON / OFF and the pilot remains lit.
If more than seven days has passed since the main burner has been cycled ON / OFF and the pilot is also out, follow the procedures described in this manual to light the pilot.
NOTE: MILLIVOLT UNITS WITH 7 DAY TIMER ­ When lighting pilot, the Pilot Knob must be pressed until a BEEP is heard. This procedure may take up to TWO MINUTES.

IPI Electronic Ignition System

Overview
The IPI system is an advanced burner controller that provides you with the option of having either a StandingPilot, or an intermittent igniting system. This alternating mode is controlled by the CPI/IPI Switch (Continuous Pilot Ignition/Intermittent Pilot Ignition) located on the IPI System Box. The difference between a Standing-Pilot and an Intermittent-Pilot is in whether the pilot stays lit or shuts off:
In Standing-Pilot, the pilot assembly is lit by the IPI Main Module and continues to stay lit until 1) the CPI/IPI Switch is switched to the IPI position; 2) a loss of electrical power (battery and AC source), 3) the flame sensor loses its signal, 4) the fuel supply discontinues, or 5) the IPI Main Module malfunctions.

UHS Box Cover
Backup Battery Pack
Remote Receiver Module
CPI / IPI Switch

In the Intermittent-Pilot mode, the pilot shuts off when the appliance is not in use. The advantage of this mode is that fuel is not consumed when the fireplace is not operating.
NOTE: In some jurisdictions Intermittent-Pilot is required. That means the pilot cannot remain lit when the appliance is not operating.
Components The core of the IPI system is the Main Module and the IPI Valve. With these two components the system is able to operate a gas fireplace. There are also other components available to complement the IPI system.

IPI Module Fan Control Module
AC Adapter Plug In

IPI System Cover: Is essential in keeping the components at
their proper operating temperatures. DO NOT OPERATE THE APPLIANCE WITHOUT THIS COVER.

Modulating Servo Motor: Is an add-on valve component that permits HI/LO functionality to be controlled by the remote. Contrary to this feature is a Manual HI/LO Control Knob. The Modulating Servo Motor requires the Remote system to be present.

Backup Battery Pack: This component permits the IPI system to operate without the need for an external AC Adapter power source. The advantage to using the battery backup is that in the case of a power failure, the appliance is still operable.

NOTE: In certain instances the IPI Main Module requires resetting. This can occur if the system is unable to ignite the pilot or the main burner in the allotted time period. The IPI is programmed to lockout all commands. To reset this lockout you must deplete the system of all electrical power. This means to remove the batteries from the Battery Pack, remove the batteries from the Remote Receiver (if applicable), and disconnect the AC Adapter from the system. Leave the power off for approximately 25 seconds to clear its lockout.

Remote Receiver: This component provides the capability of controlling the appliance with a wireless remote transmitter.

Standing Pilot Mode for Colder Climates (Below Freezing) 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.
NOTE: The pilot system for this appliance may be equipped with a Seven Day Timer, in which case the pilot flame will be extinguished if the main burner has not been turned ON for seven days. This Seven Day Cycle is reset every time the main burner is cycled ON / OFF and the pilot remains lit. If more than seven days has passed since the main burner has been cycled ON / OFF and the pilot is also out, follow the procedures described in this manual to light the pilot.
