New York City, NY:

These ﬁreplaces are approved for installation in New York City in the US state of New York.

COLD CLIMATE INSULATION

For cold climate installations, seal all cracks around the 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 the appliance rests, if ﬂoor is above ground level. Gas line holes and other openings should be caulked or stuffed with unfaced ﬁberglass insulation. If the ﬁreplace is being installed on a cement slab, in cold climates, 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.

LOCATION

To provide for the lowest possible shelf surface use the alternate rear vent outlet with attached

In selecting the location, the aesthetic and functional use of the appliance are primary concerns. However, vent system routing to the exterior and access to the fuel supply are also important. Consideration should be given to trafﬁc ways, furniture, draperies, etc., due to elevated surface temperatures (Figure 4). The location should also be free of electrical, plumbing or other

venting routed in a way to minimize obstructions to the use of the space above the appliance.

Do not insulate the space between the appliance and the area above it. See Figure 9. The mini-

mum height from the base of the appliance to the underside of combustible materials used to construct a utility shelf in this fashion is shown in the Table in Figure 9.

Appliance and Vent Clearances

The appliance is approved with zero clearance to combustible materials on all sides (as detailed in Table 8), with the following exception: When the unit is installed with one side ﬂush with a wall, the wall on the other side of the unit must not extend beyond the front edge of the unit. In addition, when the unit is recessed, the side walls surrounding the unit must not extend beyond the front edge of the unit. See Figure 4.

Vertical installation clearances to combustible mantels vary according to the depth of the mantel. See Figure 8. Mantels constructed of non-combustible materials may be installed at any height above the appliance opening; however, do not allow anything to hang below the hood.

Proper Sizing of Gas Line

Properly size and route the gas supply line from the supply regulator to the area where the appliance is to be installed per require ments outlined in the National Fuel Gas Code, NFPA 54 - latest edition (USA) or B149 - latest edition (Canada).

Never use galvanized or plastic pipe. Refer to ply line, if black iron pipe is being used. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. We recommend that a qualiﬁed individual such as a plumber or gas ﬁtter be hired to correctly size and route the gas supply line to the appliance. Installing a gas supply line from the fuel supply to the appliance involves numerous considerations of materials, protection, sizing, locations, controls, pressure, sediment, and more. Certainly no one unfamiliar and unqualiﬁed should attempt sizing or installing gas piping.

Notes:

• All appliances are factory-equipped with a ﬂexible gas line connector and 1/2 inch shutoff valve (see

• See for additional requirements for installations in the state of Massachusetts in the USA.

• The gas supply line should Not be connected to the appliance until

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 48 on Page 24 ).

Massachusetts Requirements on Page 4

Step 6 (Page 24 ).

• A pipe joint compound rated for gas should be used on the threaded joints.

Ensure propane

resistant compounds are used in propane applications. Be very careful that the pipe compound does not get inside the pipe.

• It is recommended to install a sediment trap in the supply line as close as possible to the appliance (see

Figure 48 ). Appliances using Propane should have a sediment trap at the base of the tank.

• Check with local building ofﬁcial for local code requirements (i.e. are below grade penetrations of the gas line allowed?, etc).

IMPORTANT: If propane is used, be aware that if tank size is too small (i.e. under 100-lbs, if this is the only gas appliance in the dwelling. Ref. NPFA 58), there may be loss of pressure, resulting in insufﬁcient fuel delivery (which can result in sooting, severe delayed ignition or other malfunctions). Any damage resulting from an improper installation, such as this, is not covered under the limited warranty.

Step 3. INSTALL THE VENT SYSTEM

General Information

-B149.2 in Canada.

When the rear vent collar is being used, from

inside the ﬁrebox, remove the two screws securing the lintel to the rear wall of the ﬁrebox, then remove the lintel. Remove the four cover plate securing screws.

Remove and discard the cover plate. Rein stall and securely tighten all four cover plate screws. Re-secure the lintel to the rear wall of the ﬁrebox.

Vent Restrictor Installation

A vent restrictor may be needed when vertically terminating the vent system above the roof (when using the appliance top vent), install vent restrictor in the top vent of the ﬁreplace

outlet on LMDV-3530/4035 and LMDVT-3328 series models. If needed, install the restrictor orientated as shown, either from inside or outside the unit,in the inner ﬁreplace collar.

(Top Vent)

Use only approved venting components. See Approved Vent Components on Page 2.

These ﬁreplaces must be vented directly to the outside.

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.

Preparing the Appliance Vent Collar on LMDV3530/4035 Series (Combined Top and Rear Vent) Models.

Each of the unit's two vent collars are sealed with a cover plate and a seal plate and gasket. The cover, and seal plate and gasket must be removed from the vent collar being used. Refer to

Figure 16 for top vent usage and Figure 17 for rear, and the following steps to prepare the appropriate collar for use.

From the vent collar being used, remove the four screws securing the vent seal plate and gasket. Remove and discard the seal plate and gasket.

When the top vent collar is being used, from inside the ﬁrebox, loosen the two screws in the keyhole slots of the cover plate and remove the remaining two cover plate securing screws. Remove and discard the cover plate.

Reinstall

and securely tighten all four screws.

WARNING

Failure to reinstall and securely tighten cover plate screws could result in leakage of ﬂue products into the living space. Vent cover plate and vent seal plate must remain securely installed on unused vent collar. Failure to do so could result in leakage of ﬂue products into living space.

VERTICAL TERMINATION SYSTEMS (ROOF)

See Figure 20 on Page 12 and Figures 2832 on Pages 15 and 16 and their associated

Vertical Vent Tables which illustrate the various vertical venting conﬁgurations that are possible for use with these appliances. applications are shown in these Figures; 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 speci ﬁed in ANSI Z223.1-(latest edition) (In Canada, the current CAN-1 B149 installation code) by major building codes. Always consult your lo cal codes for speciﬁc requirements. A general guide to follow is the Gas Vent Rule (refer to

Figure 5 on Page 5 ).

Vertical (Straight) Installation

Determine the number of straight vent sections required. 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2" (876 mm) and 461/2" (1181 mm) net section lengths are available (see

Table 11 and Page 31 - Item 3). Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Refer to the Vent Section Length Chart.

Vertical (Offset) Installation

Analyze the vent routing and determine the quantities of vent sections and number of elbows required. Refer to

Vertical Vent Figures and

Tables on Pages 15 and 16 to select the type

of vertical installation desired. Vent sections are available in net lengths of 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). Refer to the Vent Section Length Chart on Page 12 for an aid in selecting length combinations. Elbows are available in 90° and 45° conﬁgurations. Refer to Figure 24 on Page 14 for the SV4.5E45 and SV4.5E90 elbow dimensional speciﬁcations.

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 screws.

Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical elements. Clearances for all horizontal elements are 3" (76 mm) on top, 1" (25 mm) on sides and 1" (25 mm) on the bottom.

A. 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 (Figure 21).

To attach a vent component to the appliance collar, align the dimpled end over the collar, adjusting the radial alignment until the four locking dimples are aligned with the inlet of the four inclined channels on the collar vent component against the collar 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 is not required as the pipe will securely lock when twisted.

Note: An elbow may also be attached to the appliance collar. Attach in the same manner as you would a vent section.

C. 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.

(refer to Figure 22). Push the

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 lock ing 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 22.

D. 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 (H3907) may be used to obtain the required clearances indicated here. See installation accessories Pages 31 & 32.

E. Support the vertical vent run sections -

Note - Proper venting support is very important. 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.

If desired, sheet metal screws #6 x 1/2" length may be used to secure the support straps to the vent pipe. Refer to Figure 23.

F. Change vent direction to horizontal/inclined run - At transition from or to a horizontal/in-

clined 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.

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

straight vent sections in horizontal/inclined run as described in every 5 ft. (1.52 m) along horizontal/inclined vent runs using conventional plumber’s tape.

See Page 17, Figure 33. 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. 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: 1" (25 mm) at all sides for all vertical runs; and 3" (76 mm) at the top, 1" (25 mm) at sides, and 1" (25 mm) at the bottom for all horizontal/inclined runs.

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

I. Install the roof ﬂashing - Extend the vent sections through the roof structure. Install the roof ﬂashing over the vent section and position such that the vent column rises vertically (use carpenters level) (Figure 26). Nail along perimeter to secure ﬂashing or adjust rooﬁng to overlap the ﬂashing edges at top and sides only and trim where necessary. Seal the top and both sides of the ﬂashing with waterproof caulking.

J. Install the storm collar - Install the storm collar, supplied with the ﬂashing, over the vent/ﬂashing joint. See Figure 26. Loosen the storm collar screw. Slide collar down until it meets the top of the ﬂashing. Tighten the adjusting screw. Apply non-combustible caulking or mastic around the circumference of the joint to provide a water tight seal.

Figure 26

K. Install the vertical termination - The ﬁnal

step involves installation of the SV4.5CGV-1 Vertical Termination. Extend the vent sections to the height as shown in the "Vertical vent termination section" in SV4.5CGV-1 Vertical Termination

Figure 5 on Page 5. The

(Figure 27)

can be installed in the exact same fashion as any other Secure Vent section. Align the termination over the end of the previously installed section, adjusting the radial alignment until the four locking dimples of the termination are aligned with the inlets of the four incline channels of the last vent section. Push the termination down until it fully engages, then twist the termination clockwise running the dimples down and along the incline channels until they are seated at the end of the channels.

Figure 27

If the vent system extends more than 5 feet (1.5 m) above the roof ﬂashing, stabilizers may be necessary. Additional screws may be used at section joints for added stability. Guide wires may be attached to the joint for additional sup port on multiple joint conﬁgurations.

Notes:

• 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.

• 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), SF4.5HF (Secure Flex)ﬁrestop/spacer must be used anytime vent pipe passes through a combustible wall.

• 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.

• AN ELBOW IS ACCEPTABLE AS 1 FOOT OF VERTICAL RISE EXCEPT WHERE AN ELBOW IS THE ONLY VERTICAL COMPONENT IN THE SYSTEM (See Figure 37).

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.

Notes:

• Secure Vent

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

•

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.

•

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), SF4.5HF (Secure Flex) ﬁrestop/spacer must be used anytime vent pipe passes through a combustible wall.

• 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.

•

The tables show a 1(V) to 5(H) ratio up to a maximum horizontal run of 20 feet except for installations where an elbow is the only vertical vent section in the system (see Figure 37).

• AN ELBOW IS ACCEPTABLE AS 1 FOOT OF VERTICAL RISE EXCEPT WHERE AN ELBOW IS THE ONLY VERTICAL COMPONENT IN THE SYSTEM. See Figure 37.

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 adapter that can be ﬁtted to 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 (see also Figure 43): 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, approximately 1/2 inch from the end.

3. Pull and extend the inner ﬂexible vent pipe.

4. Slide the inner ﬂex pipe over the adapter col-

lar. 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 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.

the outer 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 outer adapter collar; to the grooves of the collar which extend approximately 1 inch from the end and to the ﬂat surface, approximately 1-3/8 inches from the end.

3. Pull and extend outer ﬂexible vent pipe.

4. Slide the outer ﬂex pipe over the adapter col-

lar. Ensure the ﬂexible vent pipe completely engages the adapter collar to a distance of 1-3/8 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 connec tion.

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 44. Space out the internal ﬂex vent spacers evenly - approximately every 6 inches - and avoid kinking of inner pipe. Support horizontal sections of ﬂex with metal straps at 2 foot (0.61 m) intervals.

Step 4. FIELD WIRING

CAUTION

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous appliance operation.

CAUTION

Ensure that wires are positioned away from hot surfaces and sharp edges.

CAUTION

Do not connect the optional wall switch for burner operation to a 120 Volt AC power supply.

Refer to Section A for millivolt appliances and Section B for electronic appliances. The gas valve is set in place and pre-wired at the factory on both models.

A. SIT and Honeywell Millivolt Wiring

(See Figure 45)

1. Select any of the following optional controls:

appliance-mounted (rocker switch) or wallmounted switch, thermostat, or one of the optional remote control kits. If appliancemounted ON/OFF control is selected mount it in the gas valve mounting bracket.

2. If wall-mounted ON/OFF control or ther-

mostat is selected mount it in a convenient location on a wall near the ﬁreplace.

3. Wire the control within the millivolt control

circuit using the 15 feet of 2 conductor wire supplied with the unit .

Caution: do not connect the optional wall switch to a 120V power supply.

4. Alternatively, the appliance may be operated

without the use of the controls indicated in step 1, solely by manipulating the gas valve control knob. In order to use this method, twist the free ends of the two conductor wire (which would otherwise go to the standard ON/OFF switch or Optional Switch) together as shown in

Figure 45. Note: Wire is located

inside the control compartment

Note: The supplied 15 feet of 2 conductor wire has one end of each conductor connected to the gas valve circuit and the other end of each conductor placed loose inside the control compartment.

B. Electronic Wiring (See Figure 47) –

Note: The electronic appliance must be con-

nected to the main power supply.

The junction box is located on the right side of the appliance. It contains a factory installed and wired outlet box (duplex receptacle). Also, an optional ﬁeld-provided junction box with recep tacle may be installed at the front of the control compartment on either side of the cabinet.

See

Figure 46. It will be held in place by a conduit

ﬁtting and locknut (ﬁeld-provided).

1. Route a 3-wire 120Vac 60Hz 1ph power supply

to the appliance junction box.

2. If the factory-provided outlet/junction box at

the right rear of the ﬁreplace is being used, remove the outlet box from the junction box by removing two screws.

3. Connect the power supply wires (including

the ground supply wire) as shown in

47. (If the ﬁeld-provided J-box/outlet box is being used, all of the outlet box wiring must be ﬁeld-provided).

4. Locate and install a low voltage (24V) wall-

mounted switch or thermostat (both ﬁeldprovided)in the desired location.

5. Connect the low voltage wire, located inside

the control compartment, to the wall-mounted switch or thermostat.

The supplied 15 feet of 2 conductor wire

Note:

has one end of each conductor connected to the gas valve circuit and the other end of each conductor placed loose inside the control compartment.

6. Insert the control circuit plug into the un-

switched receptacle of the outlet box.

7. After wiring is complete, mount the outlet box

to the J-Box.

Note: The gas valve-mounted ON/OFF switch is shown in Figure 47. It is integral with the gas valve and should be set to the ON position.

Ground supply lead must be connected to the wire attached to the green ground screw located on the outlet box. See Figure 47. 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).

CAUTION

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

*A Sediment Trap is recommended to prevent moisture and debris in gas line from damaging the valve.

Note:The gas supply line must be installed in accordance with building codes by a qualiﬁed installer approved and/or licensed as requed by the locality. In the Commonwealth of Massachusetts, installation must be performed by a licensed plumber or gas ﬁtter.

Figure 48 - GAS CONNECTION

Step 6. CONNECTING GAS LINE

Make gas line connections. All codes require a shut-off valve mounted in the supply line. 48 illustrates two methods 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 (where permitted) in connecting the appliance 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

Figure 48 for ﬂex line description. The ﬂex line is rated for both natural gas and propane gas. A manual shut off valve is also provided with the ﬂex line.

The incoming gas line should be piped into

the valve compartment and connected (see Figures 48 & 49). The millivolt control valve has a 3/8" (10 mm) NPT thread inlet port. The electronic control valve has a 1/2" (13 mm) NPT thread inlet port and is ﬁtted with a 1/2" x 3/8" (13 mm x 10 mm) NPT ﬁtting.

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

Optional: Seal around the gas line to prevent cold air leakage.

Figure

TEST ALL CONNECTIONS FOR GAS LEAKS (FACTORY AND FIELD):

WARNING

Never use an open ﬂame to check for leaks.

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

A. Light the appliance (refer to the lighting

instructions label in control compartment or homeowner's manual).

B. Brush all joints and connections with the gas

leak test solution to check for leaks. If bubbles are formed, or gas odor is detected, turn the gas control knob (off/pilot/on) to the “OFF” position. Either tighten or refasten the leaking connection, then retest as described above.

C. When the gas lines are tested and leak free be

sure to rinse off the leak testing solution,

D. Turn on burner then observe the individual

tongues of ﬂame on the burner. Make sure all ports are open and producing ﬂame evenly across the burner. If any ports are blocked, or partially blocked, clean out the ports.

CONTROL COMPARTMENT ACCESS / LOUVER PANEL INSTRUCTIONS (Ref.

Figure 49 )

NOTE: The top louvered panel and the bottom

louvered control panel door remove and install the same way as follows:

The gas controls can be found behind the control compartment access door.

Removing Control Compartment Door:

Open the door by gently lifting it upward until the hook catches on both sides clear the locating slots. Then pull door out to remove.

On millivolt systems, the piezo igniter, HI/LO ﬂame adjustment knob, and pilot and main gas OFF/ON control knob are located below the glass panel enclosure. The gas valve for electronic systems is also located below the glass enclosure panel. See

Note: Using a soapy water solution

Step 7. CHECKING APPLIANCE OPERATION

With the gas line installed, run initial system checkout before closing up the front of the appliance. Follow the pilot lighting instructions provided in the Homeowner's Care and Opera tion Instructions. For piezo igniter location see

Figure 50 (millivolt appliances only).

Note: The (pull-out) Lighting instructions label can be found in the control compartment (see Figure 50).

When ﬁrst lighting the appliance, it will take a few minutes for the line to purge itself of air. Once purging is complete, the pilot and burner will light and operate as indicated in the instruction manual. Subsequent lightings of the appliance will not require such purging. Inspect the pilot ﬂame.

SIT and Honeywell 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 ( 51 - SIT, Figure 52 - Honeywell )

To light the burner; rotate the gas valve control knob counterclockwise to the “ON” position then turn “ON” the OFF/ON switch (installed at

Step 4).

Step 10. BURNER ADJUSTMENTS Flame Appearance and sooting

Proper ﬂame appearance is a ﬂame which is blue at the base and becomes yellowish-orange in the body of the ﬂame. When the appliance is ﬁrst lit, the entire ﬂame may be blue and will gradually turn yellowish-orange during the ﬁrst 15 minutes of operation. If after a short period the ﬂame stays lowered blue, or if the ﬂame is orange with evidence of sooting (black tip), the air shutter opening may need to be adjusted.

If the air shutter openings closed too far, sooting may develop. 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. Soot ing is caused by incomplete combustion in the ﬂames and lack of combustion air entering the air shutter opening. To achieve a warm yellowish-orange ﬂame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Air Shutter Adjustment Guidelines

• If there is smoke or soot present, ﬁrst check the log set positioning to ensure that the ﬂames are not impinging on any of the logs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased.

• The more offsets in the vent system, the larger the air shutter opening will need to be.

• An appliance operated with the air shutter opened too far, may have ﬂames that appear blue and transparent. These weak, blue and transparent ﬂames are termed anemic.

• Propane models may exhibit ﬂames which

candle or appear stringy. If this is present and persists, adjust the air shutter to a more closed position, then operate the appliance for a few more minutes to ensure that the ﬂame normalizes and the ﬂames do not appear sooty.

The following chart is provided to aid you in achieving the correct air shutter adjustment for your installation.

Before installing the cap, attach manometer to the manifold side pressure test ﬁtting and adjust screw until pressure reads 3.5 inches water column (0.87 kPa) for natural gas, and 10.0 inches water column (2.49 kPa) for propane gas.

See Figure 68 and replace the pilot oriﬁce as follows: Remove the Igniter assembly retainer clip, and carefully remove the Igniter assembly.

Exercise extreme care to prevent damage to or breakage of the Igniter assembly. Remove the screw securing the pilot assembly to its mounting bracket. Back off the ﬂare nut at the end of the pilot gas line to free the pilot assembly from the gas line. Remove the pilot oriﬁce and replace it with the one provided with the conversion kit. Reinstall the pilot assembly by reversing the steps detailed here.

When reinstalling the Igniter assembly, use extreme care to prevent damage and breakage. Do not apply any leverage to the Igniter assembly while restoring the retainer clip to its original position.
