Note: Some people are affected more than others by carbon monoxide. These may include pregnant women, people with heart or lung disease, are anemic, anyone under the influence of alcohol, and those at high altitude.

IMPORTANT:Readthisownersmanualcarefully and completely before trying to assemble, operate, or service this fireplace. Improper use of this fireplace can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

General Safety Concerns

1.If you smell gas

Shut off gas supply.

Do not try to light any appliance.

Do not touch any electrical switch; do not use any phone in your building.

Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

If you cannot reach your gas supplier, call the fire department.

2.This fireplace shall not be installed in a bedroom or bathroom.

3.Never install the fireplace

In a recreational vehicle.

4.Do not use this fireplace as a wood-burningfireplace.

5.Do not add extra logs or ornaments such as pine cones, vermiculite, or rock wool. Using these added items can cause soot build-up.

6.This fireplace is designed to be smokeless. If logs appear to smoke, turn off fireplace and call a qualified service person.

7.Avoid any drafts that alter burner flame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside burn area of the firebox. Ceiling fans may create drafts that alter burner flame patterns. Soot build-upand improper burning will occur. Sootbuild-upcan settle on household surfaces outside the fireplace.

8.This fireplace needs fresh air ventilation to run properly.

The Vent free decorative gas log set must have an oxygen depletion sensor (ODS) pilot light safety system. The ODS shuts down the fireplace if not enough fresh air is available. See Air for Combustion and Ventilation, page 8. If the fireplace keeps shutting off, see appliance manufacturers’ troubleshooting instructions.

9.Do not run fireplace

Where flammable liquids or vapors are used or stored.

Under dusty conditions.

10.Do not use this fireplace to cook food or burn paper or other objects.

11.Never place any objects in the fireplace or on logs.

12.Fireplace screens must be provided and are to be closed before operating the decorative room heater. If doors are installed, they must be open during operation. Fireplace front and screen become very hot when running fireplace. Keep children and adults away from hot surfaces to avoid burns or clothing ignition. The fireplace will remain hot for a time after shut down. Allow surfaces to cool before touching.

13.Carefully supervise young children when they are in the room with the fireplace.

14.Do not use fireplace if any part has been exposed to or under water. Immediately call a qualified service technician to inspect the fireplace and to replace any part of the control system and gas control which has been under water.

15.Do not operate the fireplace if any log is broken. Do not operate the fireplace if a log is chipped (dime-sizedor larger). Verify proper log placement prior to operating appliance.

16.Turn fireplace off and let cool before servicing. Only a qualified service person should service and repair the fireplace.

17.Operating the fireplace above elevations of 4,500 feet may cause pilot outage.

DO NOT USE OR STORE GASOLINE OR OTHER FLAMMABLE LIQUIDS OR GASES IN OR NEAR THE

FIREPLACE!

Projected installations can extend any distance into the room. A projection may be ideal for a new addition on an existing, finished wall.

Corner installations make use of space that may not normally be used and provides a wider and more efficient range for heat disbursement.

An internal wall installation provides a discreet option for room separation and can also be ideal as an addition to an existing wall.

IMPORTANT:Vent-freeheatersaddmoisturetotheair.Installinga fireplace in rooms without enough ventilation air may cause mildew to form from too much moisture.

IMPORTANT: Make sure the fireplace is level. If the fireplace is not level, the log set will not work properly.

Attention: You may need a building permit to install a Grand Meridian fireplace. Check with the local jurisdiction before you get started.

Supporting Floor Systems

Floor Framing

It is important to take into consideration that the load for the Grand Meridian Fireplace is considerable, but, more important, that it is a dead load that will have to be absorbed by a relatively small amount of existing floor space.

It is the ultimate responsibility of the installer to ensure that proper concrete slab supports are used.

WARNING to the licensed design professional and/or building contractor: It is your responsibility to be certain that the Grand Meridian can be properly supported by the combustible floor system on which the fireplace will rest.

For fireplace support foundations installed on concrete refer to Appendix I and II (pages 17 & 18) for specific instructions.

Rebar locations

Lay-outthe position of the fireplace and drill holes where the rebar will be located. Secure the #3 rebar 4 inches into the concrete foundation with ITW Epoxy or Simpson Epoxy. Follow manufacturer’s instructions for installation of rebar into slab.

Wood Floor

Anchorage of fireplace to wood floor construction is required. Refer to Figure 8 for anchorage dimensions. Four anchors are required to attach to thesub-flooringframing.

Crawl Space or Upper Floor:

For installation of firebox over combustible crawl spaces or upper floors, anchorage of the firebox is required. Illustrations of examples of possible anchorage methods are shown in Figures 5 thru 7 depending upon the type of floor framing. Final method of anchorage is to be determined by licensed design professional.

6

For conventional framing, where the floor joists are parallel with the sides of the firebox, the addition of floor joists to align with the anchor brackets allows the brackets to be directly connected to the floor joists.

Note that additional floor joists may be required to support the weight of the firebox and chimney. Where the floor joists run paralleltothefrontofthefirebox,anchoragecanbeaccomplished in like manner as shown in Figure 5 using blocking between the floor joist.

For floors supported by I-Joists,the method of anchorage is illustrated in Figures 6 and 7. Figure 10 illustrates the general arrangement of anchorage to floor framing.

It is important to take into consideration that the load for the Grand Meridian Fireplace must be considered as additional dead load that will have to be supported by the floor framing. Additional floor joists or I-joistsmay be required as determined by the licensed design professional.

The dead weights for the fireplace are noted in Table I. It is the task and responsibility of the general contractor/installer to see that the proper reinforcement for weight loads are made by a licensed design professional prior to the fireplace installation.

As stated above, it is desirable to place additional framing for alignment of anchor rods. Refer to Figure 10 for anchor rod locations.

Clearances

The Importance of Clearances

Warning to the structural engineer and/or building contractor: It is your responsibility to be certain that the Grand Meridian Fireplace can be properly supported by the combustible floor system on which the fireplace will rest. Be advised that this engineering equation will be in addition to any live or dead weights that the floor has to carry.

Clearances to Combustibles

Nothing is more important than paying strict attention to giving clearance between fireplace surfaces and surrounding “combustibles” the most common of which are:

Drywall

Wood flooring

Plywood sub-flooring

Framing materials

Particle board

Mill board

Plywood paneling

Required Clearances are:

 

Unit front, sides, rear:...........................................

0"

Combustible Floor: ..............................................

0"

Combustible Sheathing above opening top: .......

8" (200 mm)

Sheathing or trim to opening sides: .....................

8" (200 mm)

Mantle above opening: ........................................

12" (300 mm)

Opening to sidewall: ............................................

24" (500 mm)

Insulation from firebox: ........................................

0"

The Grand Meridian Vent-Freefireplace may be installed at “zero clearance” to plywood sheathing and to uninsulated wood framing members at the unit bottom, sides, rear and top when used for enclosing any listedvent-freegas-firedlog set with maximum heat input ratings up to 40,000 Btu/hr. However, when aVent-Freefireplace is to be installed on carpeting, wood flooring, or any combustible material other than tile or concrete, the Vent-Free fireplace shall then be installed on a metal or wood platform extending the full width and depth of the VentFree fireplace.

Clearance to Combustible Trim:

Grand Meridian Vent-FreeFireplaces are designed to be custom finished with facing trim and mantle to be an owner option. However, all such trim material must meet standard fireplace code requirements.

Non-combustiblefacing material must be applied to a minimum of eight inches (8”) beyond the sides of the finished opening of theVent-Freefireplace andnon-combustiblefacing material must cover a minimum of twelve inches (12”) above the finished opening of the installed unit.

Clearance to combustible trim are those distances required to ensure that combustible mantle and facing material will not be exposed to excessive heat while the unit is operating.

These clearances should be adequate to prevent discoloration or warping of trim facings due to heat. However, circumstances unique to each installation create variables that may be beyond the scope of this manual. Therefore be sure to follow gas log appliance manufacturer’s explicit installation instructions regarding all minimum trim facing, mantle height and side wall clearance requirements.

Figure 13

Parts of the combustible mantle assembly located above and projecting more than one and one-halfinches(1-1/2”)inches from the firebox opening shall be kept at least twelve inches (12”) from the top of the opening.

Mantle shelves with horizontal projection of ten inches (10”) from the face of the fireplace must be held to a minimum vertical distance of twenty inches (20”) from the top of the finished fireplace opening.

Note: Mantle height clearances may vary among gas log appliance manufacturers or with the use of firebox canopies.

Be sure to follow the gas log appliance manufacturer’s explicit installation instructions for mantle height clearance requirements.
