Step 3. INSTALL THE VENT SYSTEM

General Information

These fireplaces are designed, tested and listed for operation and installation with, and only with, Secure Vent™ Direct Vent System Components, Secure Flex™ Flexible Vent Components manufactured by Security Chimneys International and Z-FLEX™ Model GA Venting Systems listed to UL1777 and ULCS635 manufactured by Flexmaster Canada Limited. These approved vent system components are labeled for identification. DO NOT use any other manufacturer's vent components with these appliances.

These fireplaces must be vented directly to the outside.

Determine the venting for the appliance. If the vent run will include at least 8 feet of vertical rise, then install the second restrictor in the appliance collar before connecting any vent (Refer to tor inside the fixed restrictor.

Note: The second restrictor is included within the firebox.

Figure 12

Exhaust Vent

). Place the second restric-

Fixed Restrictor

The vent system may not service multiple appliances, and must never be connected to a flue serving a solid fuel burning appliance. The vent pipe is tested to be run inside an enclosing wall (such as a chase). There is no requirement for inspection openings in the enclosing wall at any of the joints in the vent pipe.

Select Venting System - Horizontal or Vertical

With the appliance secured in framing, determine vent routing and identify the exterior termination location. The following sections describe vertical (roof) and horizontal (exterior wall) vent applications. Refer to the section relating to your installation. A list of approved

venting components is shown in the tables on page 26.

VERTICAL TERMINATION SYSTEMS (ROOF)

Figures 13, 17 and 23 through 25 on pages 12, 14 and 15

and their associated Vertical Vent Tables illustrate the various vertical venting configurations that are possible for use with these appliances. Secure Vent pipe applications are shown in these figures; Secure Flex pipe may also be used.

A Vertical Vent Table summarizes each system’s minimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications.

Both these vertical vent systems terminate through the roof. The minimum vent height above the roof and/or adjacent walls is specified in ANSI Z223.1-(latest edition) (In Canada, the current CAN-1 B149 installation code) by major building codes. Always consult your local codes for specific requirements. A general guide to follow is the Gas Vent Rule (refer to

Q T Y

Where required, a telescopic vent section (SV4.5LA) may be used to provide the installer

with an option in installing in tight and confined spaces or where the vent run made up of fixed length pieces develops a joint in a undesirable location, or will not build up to the required length. The SV4.5LA Telescopic Vent Section has an effective length of from 1-1/2" (38 mm) to 7-1/2" (191 mm).

The SV4.5LA is fitted with a locking inclined channel end (identical to a normal vent section component) and a plain end with 3 pilot holes. Slip the plain end over the locking channel end of a standard SV4.5 vent component the required distance and secure with three #8 x 3/8" screws.

Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical vent elements.

Clearances for horizontal vent elements are 1" (25 mm) at the sides and 1" (25 mm) on the bottom. Clearances above horizontal vent elements are 3" (76 mm) for all models and all applications.

Exception: Clearance is 5" (127 mm) for MPLDV35, MPLDV40 & MPLDV45, when the center line of the horizontal run is less than 48" (1219 mm) above the fireplace top wrapper surface.

The starter elbow may not be used if a 45 degree vent run is required directly off of the unit. Refer to

Detail - Figure 17

A. Attach Supplied 45 Degree Starter Elbow -

Slip the plain end with 3 mounting holes over the locking channel end of the appliance collar and secure with three screws.

B. Support The Elbows - Support the starter elbow and the vertical portions of the venting system with support bracket as shown in

Figure 23

- Detail A, on page 14. Do not use

the starter elbow anywhere else in the vent system if not used on the appliance collar. SV4.5 rigid and flex components can be used directly off the collar. Do not return to rigid sections after using flex sections in a vent run.

C. Frame ceiling opening - Use a plumb line from the ceiling above the appliance to locate center of the vertical run. Cut and/or frame an opening, 10-1/2" x 10-1/2" (267mm x 267mm) inside dimensions, about this center mark (

D. Attach vent components to 45 degree starter elbow - Secure Vent SV4.5 direct vent

system components are unitized concentric pipe components featuring positive twist lock connections (

see Figure 15

All of the appliances covered in this document are fitted with collars having locking inclined channels. The dimpled end of the vent components fit over the appliance collar to create the positive twist lock connection.

First Vent Component

Align the dimple (four places) with the opening of the locking incline channel on appliance collar. Twist vent component clockwise to engage and seal.

Figure 15

To attach a vent component to the 45 degree starter elbow, align the dimpled end over the elbow, adjusting the radial alignment until the four locking dimples are aligned with the inlet of the four inclined channels on the collar

refer to Figure 15

(

Push the vent component against the starter elbow until it fully engages, then twist the component clockwise, running the dimples down and along the incline channels until they seat at the end of the channels.

The unitized design of the Secure Vent components will engage and seal both the inner and outer pipe without the need for sealant or screws. If desired a #6 x 1/2" screw may be used at the joint, but it is not required as the pipe will securely lock when twisted.

Note: Always use the starter elbow directly at the appliance 45° collar unless rigid straight pipe of flex pipe is used, as shown in Figure 17.

E. Attach vent components to each other - Other

vent sections may be added to the previously installed section in accordance with the requirements of the vertical vent figures and tables. To add another vent component to a length of vent run, align the dimpled end over the inclined channel end of the previously installed section, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels of the previous section. Push the vent component against the previous section until it fully engages, then twist the component clockwise running the dimples down and along the incline channels until they seat at the end of the channels.

This seating position is indicated by the alignment of the arrow and dimple as shown in

Figure 16.

F. Install firestop/spacer at ceiling - When

using Secure Vent, use SV4.5VF firestop/spacer at ceiling joists; when using Secure Flex, use SF4.5VF firestop/spacer. If there is living space above the ceiling level, the firestop/spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the firestop/spacer must be installed on the top side of the joist.

Route the vent sections through the framed opening and secure the firestop/spacer with 8d nails or other appropriate fasteners at each corner. Remember to maintain 1" (25 mm)

clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections. Attic insulation shield (96K94) may be used to obtain the required clearances indicated here. See installation accessories table on page 25.

G. Support the vertical vent run sections -

Note - Proper venting support is very impor-

tant. The weight of the vent must not be supported by the fireplace in any degree.

Support the vertical portion of the venting system every 8 feet (2.4m) above the fireplace vent outlet. One method of support is by utilizing field provided support straps (conventional plumber's tape). Secure the plumber's tape to the framing members with nails or screws.

H. Change vent direction to horizontal/inclined run - At transition from or to a horizon-

tal/inclined run, install the SV4.5E45 and SV4.5E90 elbows in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar section to align with the required direction of the next vent run element. Twist elbow sections in a

clockwise direction only so as to avoid the possiblity of unlocking any of the previously connected vent sections. See

straight vent sections in horizontal/inclined run as described in Step E. Install support straps every 5' (1.52 m) along horizontal/ inclined vent runs using conventional plumber’s tape. It is very important that the horizontal/

inclined run be maintained in a straight (no dips) and slightly elevated plane in a direction away from the fireplace 1/4" per foot (20

mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level.

H. Frame roof opening - Identify location for vent at the roof. Cut and/or frame opening per Roof Framing Chart and

) installs in the exact

It is important to maintain the required clearances to combustibles at the top and bottom for all horizontal/inclined runs.

Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical vent elements.

Clearances for horizontal vent elements are 1" (25 mm) at the sides and 1" (25 mm) on the bottom. Clearances above horizontal vent elements are 3" (76 mm) for all models and all applications.

Exception: Clearance is 5" (127 mm) for MPLDV35, MPLDV40 & MPLDV45, when the center line of the horizontal run is less than 48" (1219 mm) above the fireplace top wrapper surface.

VERTICAL VENT FIGURES/TABLES

Note: Secure Vent (rigid vent pipe) is shown in the figures; Secure Flex (flexible vent pipe) may

also be used.

WARNING: UNDER NO CIRCUMSTANCES MAY SEPARATE SECTIONS

OF CONCENTRIC FLEXIBLE VENT PIPE BE JOINED TOGETHER.

Note: It is very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of

1/4" rise per foot (20 mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level.

Note: SV4.5VF (Secure Vent), SF4.5VF (Secure Flex) firestop/spacer must be used anytime vent pipe passes through a combustible floor or ceiling. SV4.5HF (Secure Vent) or SF4.5HF (Secure Flex) must be used anytime vent pipe passes through a combustible wall. For the MPLDV35/40/45, with a center line lower than 48" (1219 mm) above the fireplace top wrapper surface, use SV4.5HF5 or SF4.5HF5. In all cases the firestop/spacer provided with the termination may be used with the termination, frame to 5" clearance where applicable.

Note: Two 45 degree elbows may be used in place of one 90 degree elbow. The same rise to run ratios, as shown in the venting figures for 90 elbows, must be followed if 45 degree elbows are used.

the locking channel end of the appliance collar and secure with three screws.

*When using Secure Flex,

use Firestop/Spacer

SF4.5VF

**Use Firestop/Spacer SV4.5HF or SF4.5HF when using Secure Vent or Secure

Flex respectively. Use Firestop/Spacer SV4.5HF5 or SF4.5HF5 when using

Secure Vent or Secure Flex on horizontal vent runs for the MPLDV35/40/45

with a center line lower than 48” (1219 mm) above the fireplace top wrapper

surface. In all cases the firestop/spacer provided with the termination may

be used with the termination, frame to 5” clearance where applicable.

B. Support The Elbows - Support the starter

elbow and the horizontal portions of the venting system with support bracket as shown in

Figure 29 to 32

Both of these horizontal vent systems terminate through an outside wall. Building Codes limit or prohibit terminating in specific areas. Refer to

C. Plan the vent run -

Analyze the vent routing and determine the types and quantities of sections required 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2" (876 mm) and 46-1/2" (1181 mm) net section lengths are available. Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Make allowances for elbows as indicated in

Figure 18 on page 13

Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical vent elements.

Clearances for horizontal vent elements are 1" (25 mm) at the sides and 1" (25 mm) on the bottom. Clearances above horizontal vent elements are 3" (76 mm) for all models and all applications.

Exception: Clearance is 5" (127 mm) for MPLDV35, MPLDV40 & MPLDV45, when the center line of the horizontal run is less than 48" (1219 mm) above the fireplace top wrapper surface.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

F. Attach vent components to starter elbow -

To attach a vent component to the the starter elbow, align the dimpled end over the collar, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels on the collar (

Figure 15

on page 12).

refer to

Push the vent component against the elbow until it fully engages, then twist the component clockwise, running the dimples down and along the incline channels until they seat at the end of the channels. The unitized design of the Secure Vent components will engage and seal both the inner and outer pipe elements with the same procedure. Sealant and securing screws are not required.

Note: A 90 or 45 degree elbow may not be directly attached to the appliance elbow collar.

G. Attach vent components to each other -

Other vent sections may be added to the previously installed section in accordance with the requirements of the vent tables.

To add another vent component to a length of vent run, align the dimpled end of the component over the inclined channel end of the previously installed section, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels of the previous section.

Push the vent component against the previous section until it fully engages, then twist the component clockwise running the dimples down and along the incline channels until they seat at the end of the channels.This seating

position is indicated by the alignment of the arrow and dimple as shown in

Figure 16 on

page 12.

H. Install firestop/spacer at ceiling -

When using Secure Vent, use SV4.5VF firestop/ spacer at ceiling joists; when using Secure Flex, use SF4.5VF firestop/spacer.

Figure 26

If there is living space above the ceiling level, the firestop/ spacer must be installed on the bottom side of the ceiling. above the ceiling, the firestop/ spacer must be installed on the top side of the joist. Route the vent sections through the framed opening and secure the firestop/spacer with 8d nails or other appropriate fasteners at each corner.

Remember to maintain 1" (25 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections.

I. Support the vertical run sections -

On the vertical run, support the venting system every 8 feet (2.4m) above the fireplace vent outlet with field provided support straps (Plumber's tape).

Attach the straps to the vent pipe and secure to the framing members with nails or screws. See

Figure 17 on page 12.

J. Change vent direction - At transition from or to a horizontal/inclined run, install the SV4.5E45 and SV4.5E90 elbows in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar section to align with the required direction of the next vent run element. Twist

elbow sections in a clockwise direction only so as to avoid the possiblity of unlocking any of the previously connected vent sections. See

Figure 18 on page 13

K. Continue installation of horizontal/inclined sections - Continue with the installation of the

straight vent sections in horizontal/inclined run as described in Step F.

If attic space is

very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of 1/4" rise per foot (20 mm per meter) which

is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or

near level

Use a carpenter’s level to measure from a constant surface and adjust the support straps as necessary.

It is important to maintain the required clearances to combustibles at the top and bottom for all horizontal/inclined runs.

Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical vent elements.

Clearances for horizontal vent elements are 1" (25 mm) at the sides and 1" (25 mm) on the bottom. Clearances above horizontal vent elements are 3" (76 mm) for all models and all applications.

Exception: Clearance is 5" (127 mm) for MPLDV35, MPLDV40 & MPLDV45, when the center line of the horizontal run is less than 48" (1219 mm) above the fireplace top wrapper surface.

L. Assemble vent run to exterior wall - If not

previously measured, locate the center of the vent at the exterior wall. Prepare an opening as described in Step D. Assemble the vent system to point where the terminus of the last section is within 7 in. (178 mm) to 11-1/4 in. (286 mm) inboard of the exterior surface to which the SV4.5 HT-2 termination is to be attached, see

Figure 28

, it is

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Horizontal terminations have been designed to perform in a wide range of weather conditions. Our terminations meet or exceed industry standards.

When selecting the locations of your horizontal terminations, do not place the termination where water from eaves and adjoining rooflines may create a heavy flow of cascading water onto the termination cap. If the cap must be placed where the possibility of cascading water exists, it is the responsibility of the builder to direct the water away from the termination cap by using gutters or other means.

Take care to carefully follow the installation instructions for the termination, including the use of silicone caulking where required.

HORIZONTAL VENT FIGURES/TABLES

Note: Secure Vent components (rigid vent pipe and terminal) are

shown in the figures; Secure Flex components (flexible vent pipe and terminal) may also be used.

Note: Two 45 degree elbows may be used in place of one 90 degree elbow. The same rise to run ratios, as shown in the venting figures for 90 degree elbows, must be followed if 45 degree elbows are used.

Note: It is very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of

foot (20 mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level.

Note: SV4.5VF (Secure Vent), SF4.5VF (Secure Flex) firestop/spacer must be used anytime vent pipe passes through a combustible floor or ceiling. Lennox MPLDV35"/40" & 45" models require 5" clearances to combustibles above horizontal vent runs when the centerline of the horizontal vent run is at or below 48" (1219 mm) above the fireplace top wrapper. In all other instances, with these three models and with the MPLDV30 in all instances, the clearance to combustibles above horizontal vent runs is 3". Please note that to facilitate the 5" clearance when required, we have two 5" clearance firestops. The SV4.5HF5 is for use with rigid (Secure Vent™ ) and the SF4.5HF5 is for use with (Secure Flex™ ). These firestops should be used whenever horizontal vent runs meeting the use requirements detailed above, penetrate walls separating occupied rooms in a house.

VERTICAL OR HORIZONTAL VENTING USING

SECURE FLEX

KITS AND COMPONENTS

Secure Flex venting kits and components may

be used in any venting application where rigid Secure Vent (SV4.5) direct vent components can be used. All restrictions, clearances and allowances that pertain to the rigid piping apply to the flexible venting.

Secure Flex

kits may not be modified; also, under no circumstances may separate sections of flex pipe be joined together. Secure Flex kits may be added to the

end of a vent run made up of rigid Secure Vent (SV4.5) vent sections provided that doing so does not violate any of the venting length, height, routing, horizontal to vertical ratio requirements or clearance considerations detailed in this manual.

Secure Flex kits come with an included adapter that can be fitted to the appliance collar or the inclined channel end of the last Secure Vent (SV4.5) vent section in a rigid system in the exact same fashion as any other Secure Vent section. Align the dimpled end of the adapter over the previously installed section or appliance collar, adjusting the radial alignment until the four locking dimples of the adapter are aligned with the inlets of the four incline channels of the last vent section or collar. Push on the adapter until it fully engages, then twist the adapter clockwise running the dimples down and along the incline channels until they seat at the end of the channels.

Attach the flexible vent to the adapter as follows

(also see Figure 34 )

A. Install the Inner Flex Pipe -

1. Install the small gear clamp loosely around the

inner flexible vent pipe, push it back out of the way.

2. Apply a bead of Mill-Pac Black (700

°F)

high temperature sealant - Catalog No. 10K81) to the inner adapter collar, approxi-

mately 1/2 inch from the end.

3. Pull and extend the inner flexible vent pipe.

4. Slide the inner flex pipe over the adapter

collar. Ensure the flexible vent pipe completely engages the adapter collar to a distance of 1³⁄₄ inches from the end, and that it is free from damage or tears.

5. Slide the gear clamp down and tighten it fully to secure the flexible vent to the adapter inner collar approximately 3/4 inch from the end of the flex.

6. Install three screws 120 degrees apart through the flexible vent pipe and into the adapter collar just below the gear clamp to provide additional security to the connection.

B. Install the Outer Flex Pipe -

1. Install the large gear clamp loosely around

the outer flexible vent pipe, push it back out of the way.

NOTE: OUTER PIPE IS PULLED AWAY TO SHOW THE DETAIL OF THE INNER PIPE

Apply ONLY MIL-PAC BLACK HIGH TEMPERATURE SEALANT (Catalog No. 10K81) to the outside surface of both collars of the adapter (be especially careful to fill the grooves of the outer collar to be covered by the flexible pipe) and slide flexible pipe over inner and outer adapter collars.

the outer adapter collar; to the grooves of the collar which extend approximately 1 inch from the end and to the flat surface, approximately 13/8 inches from the end.

3. Pull and extend the outer flexible vent pipe.

4. Slide the outer flex pipe over the adapter

collar. Ensure the flexible vent pipe completely engages the adapter collar to a distance of 1-3/4 inches from the end, and that it is free from damage or tears.

5. Slide the gear clamp down and tighten it fully to secure the flexible vent to the adapter outer collar approximately 3/4 inch from the end of the flex.

6. Install three screws 120 degrees apart through the flexible vent pipe and into the adapter collar just below the gear clamp to provide additional security to the connection.

C. Route Flex Vent -

Ensure that the flex vent is properly routed to provide the required clearance. Do Not allow the flexible vent to bend in a radius tighter than 5" (127 mm). Refer to

Figure 35

horizontal sections of flex with metal straps at 2 foot (0.61 m) intervals.

D. Install Firestop/Spacers at ceilings and walls -

When Secure Flex penetrates a wall or ceiling, a firestop/spacer is required: use SV4.5 (Secure Vent), SF4.5 (Secure Flex) firestop/ spacer anytime vent pipe passes through a combustible floor or ceiling.

. Failure to do so will result in a potential safety hazard. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70(latest edition). (In Canada, the current CSA C22-1 Canadian Electrical Code.)

Gas Line Access Plate Not Installed At The Factory. It Is Included In The Installation Instruction Bag.

Step 5. CONNECTING GAS LINE

All codes require a shut-off valve mounted in the supply line. The orientation of the shutoff valve should face the front, as shown in

Figure 39. Figure 38

for connecting the gas supply. The flex-line method is acceptable in the U.S.,

however, Canadian requirements vary depending on locality. Installation must be in compliance with local codes.

These appliances are equipped with a gas flex line for use in connecting the unit to the gas line. A gas flex line is provided to aid in attaching the direct vent appliance to the gas supply.

The gas flex line can only be used where local codes permit. See description. The flex line is rated for both natural and propane gas. A manual shut off valve is also provided with the flex line.

The gas control valve is located in the lower control compartment.

Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds are used in propane applications).

Turn on gas supply and test for gas leaks, using a gas leak test solution (also referred to as bubble leak solution).

Note: Using a soapy water solution (50% dish soap, 50% water) is an effective leak test solution but it is not recommended, because the soap residue that is left on the pipes/ fittings can result in corrosion over time. Never

use an open flame to check for leaks. A. Light the appliance (refer to the lighting

instructions label in the control compartment or in the Homeowner's Care and Operation Instructions).

Step 6. INSTALLING THE LOGS, GLOWING EMBERS AND VOLCANIC STONES

Remove the gas line access plate and gasket from the provided plastic bag and install them over the opening, using the provided screws (4) as shown in

Refer to for the venturi air shutter. Manually actuate the air shutter through several cycles. Set the air shutter to 3/32" before placing the logs.

The logs are packaged in a carton located within the firebox. One plastic bag of glowing embers and volcanic stones are located in the bottom compartment. Refer to the Log Set Placement Supplement for detailed placement instructions for the logs, glowing embers and volcanic stones.

Proper log and twig placement is critical to encourage outstanding flame appearance and prevent sooting. These fires are designed to provide a rich orange/red glow on the logs. Ensure the bottom of the rear log is fully seated and pulled as far forward as the pins will allow. Refer to the Log Set Placement

Supplement for detailed instructions.

and loosen the set screw

Note: Log setup is by design asymmetric. The fire is intentionally positioned off center to provide a natural fire look.

Step 7. CHECKING APPLIANCE OPERATION

Millivolt Appliance Checkout

The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge.

The top 3/8" (10 mm) at the pilot generator (thermopile) and the top 1/8" min (tip) of the quick drop out thermocouple should be engulfed in the pilot flame.

The flame should project 1" (25 mm) beyond the hood at all three ports place logs if removed for pilot inspection.

To light the burner; turn “ON” the remote wall switch and rotate the gas valve control knob counterclockwise to the “ON” position (“ON” will be at the bottom side of the valve).

bottom panel forward. Retrieve the glass door. Visually inspect the

gasket on the backside of the frame. Gasket surface must be clean, free of irregularities and seated firmly.

Position the door in front of the firebox opening with the bottom of the door held away from the fireplace the door frame over the top of the firebox frame. Let the bottom of the door frame swing gently in towards the fireplace ensuring that the gasket seats evenly as the door frame draws shut. Fasten the two latches located underneath the firebox floor to the door's vee-flange. Close both the latches securely.

If desired, install the optional hood. Note the location of the three clips inside the top air channel above the door. The clips are equally spaced on the top surface of the air channel opening. Use a screwdriver to open the clips slightly if needed. Engage the back edge of the eyebrow into the clips to secure.

Step 9. BURNER ADJUSTMENTS

Flame Appearance and sooting

Proper flame appearance is a matter of taste. Generally, most people prefer the warm glow of a yellow to orange flame. Appliances operated with air shutter openings that are too large will exhibit flames that are blue and transparent. These weak, blue and transparent flames are termed anemic. If the air shutter opening is too small sooting may develop.

CAUTION: THE AIR SHUTTER DOOR AND NEARBY APPLIANCE SURFACES ARE HOT. EXERCISE CAUTION TO AVOID INJURY WHILE ADJUSTING FLAME APPEARANCE.

To adjust the flame, rotate the lever arm up or down (rod located in the lower control area). Position the air shutter to the factory setting as shown in the table in burner to operate for at least 20 minutes.

Adjustment

Arm

The adjustment rod and associated adjustable air shutter is patented technology. Flame adjustments can be made quickly and accurately to taste without the need of disassembling the appliance and waiting for 30 minutes after each adjustment.

Propane models may exhibit a flame pattern that may candle or appear stringy. If this is problematic or persists as the appliance is continually operated, adjust the air shutter closed as described in the previous paragraphs. Operate the appliance for a period of time as the effect diminishes, ensuring that the appliance does not develop sooty flames.

When satisfied that the appliance operates properly, proceed to finish the installation. Leave the control knob in the ON position and the remote switch OFF. Close the lower control compartment door.

Sooting is indicated by black puffs developing at the tips of very long orange flames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termination. Sooting is caused by incomplete combustion in the flames and lack of combustion air entering the air shutter opening. To achieve a warm yellow to orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

No smoke or soot should be present. These logs are designed to be involved in the fire. Flames will impinge the top tips of the right and left logs.

If the logs are properly positioned and sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Normally, the more offsets in the vent system, the greater the need for the air shutter to be opened further.

Burner Adjustment

WARNING: AIR SHUTTER ADJUSTMENT SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

IMPORTANT: ENSURE THAT THE FRONT GLASS PANEL IS IN PLACE AND SEALED DURING ADJUSTMENT.

COLD CLIMATE INSULATION

For cold climate installations, seal all cracks around your appliance with noncombustible material and wherever cold air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on which appliance rests, if floor is above ground level. Gas line holes and other openings should be caulked or stuffed with unfaced fiberglass insulation. In cold climates, if the fireplace is being installed on a cement slab, a sheet of plywood or other raised platform can be placed underneath to prevent conducting cold up into the room. It also helps to sheetrock inside surfaces and tape for maximum air tightness and caulk firestops.
