SAFETY CODES AND STANDARDS

The design of this firebox has been tested and approved by the C.S.A. in accordance with ANSI Z21.91b-2007 UNVENTED

FIREBOX ENCLOSURES FOR GAS-FIRE UNVENTED DECORATIVE ROOM HEATERS. This firebox is UNIVERSALLY

LISTED for use with the compatibly sized decorative type unvented room heaters, which comply with standard Volume II

Z21.11.2 of the American National Standards Institute. This manual serves only as a basic guideline for installation of this firebox and gas piping. The complete installation must be in accordance with local codes and ordinances or, in the absence of local codes, with American National Standards Institute Fuel Gas Code Z223.1/NFPA 54.

SELECTING A LOCATION FOR THE FIREBOX

This firebox may be installed at 0” clearance to combustibles at its bottom and top framing spacers. See installation instructions for other clearances.

It is imperative that adequate clearances around air openings into and away from this firebox be maintained. To ensure these clearances, do not place any object closer than 24 inches directly in front of the firebox. Do not block any openings in the firebox.

See optional location in this manual for the many ways in which this unit could be located in the home. When the firebox is installed directly on carpeting, tile, or other combustible material other than wood flooring, the firebox shall be installed on a metal or wood panel extending the full width and depth of the enclosure.

INSTALLATION INFORMATION

IMPORTANT: Before beginning the installation, check with local building officials to assure compliance with local regulations and codes, and to obtain any required permits.

A qualified installer or service agency must perform installation and service. All instructions should be read and understood prior to installing the firebox. Protective wear such as safety glasses to protect eyes and work gloves should be worn during the installation.

Heavy stone or brick facings and/or hearth extensions may require additional foundation support not located near a loadbearing wall.

The unit may be installed at zero-clearance to the floor and top framing spacers. Warning: Do not notch framing or alter the spacers. The back of the unit needs to have a 1” clearance from combustible material.

Check to see if the unit is square prior to securing. Secure the unit to framing using the built-in nailing flanges. The nailing flanges have been designed to allow the application of ½” wallboard or plywood flush with the firebox face. Directly above the unit, noncombustible wallboard should be used as specified in this instruction manual.

Do not fill the spaces around the firebox with insulation or other materials. The floor under the unit and the area above the top framing spacers should be insulated. This will reduce cold air infiltration, reduce heat loss and increase the heating efficiency of the product.

Provisions for adequate combustion and ventilation air must be provided for the decorative type unvented room heater to be installed in this firebox. Refer to the instructions supplied with the decorative type unvented room heater.

ATTENTION INSTALLER:

1. Attach with fasteners the label that was supplied with the unvented fireplace insert to the inside of the solid-fuel burning fireplace or listed unvented firebox enclosure into which the unvented fireplace insert is installed.

2. DO NOT cut any sheet metal parts of the solid-fuel burning fireplace or listed unvented firebox enclosure in which the

unvented fireplace insert is to be installed.

3. If the factory-built fireplace has no gas access hole(s) provided an access hole of 1.5 inch (37.5mm) diameter or less

may be drilled through the lower sides or bottom of the firebox in a proper workmanlike manner. This access hole

must be plugged with non-combustible insulation after the gas supply line has been installed.

4. The glass doors, screen rails, screen mesh and solid-fuel log grates can be removed from the fireplace before

installing the unvented fireplace insert.

5. If attached by fasteners the smoke shelves, shields and baffles may be removed.

6. The trim panels or surrounds shall not seal ventilation openings in the fireplace.

7. Make sure to leave adequate clearances for accessibility for purposes of servicing and proper operation.

8. Combustible flooring installation: When the vent free firebox is installed directly on carpeting, tile, or other combustible

material other than wood flooring, the vent free firebox shall be installed on a metal or wood panel extending the full

width and depth of the vent free firebox.

9. Solid fuels shall not be burned in a fireplace where an unvented room heater is installed.

MANTELS, SURROUNDS & TRIM INSTALLATION

The firebox may be finished in an infinite number of ways from rustic to contemporary using marble, stone, wood, brick, tile or various other natural or man-made materials.

CAUTION: THE BLACK PAINTED FACE OF THE FIREBOX (EXCLUDING NAIL FLANGES) MUST NOT BE

COVERED WITH COMBUSTIBLE MATERIALS. SOME MAN-MADE BRICKS OR STONES MAY

CONTAIN COMBUSTIBLE MATERIAL.

All noncombustible materials, which overlap the black painted face, must be sealed to the firebox face with a high quality heat-resistant caulk adhesive or sealant. The edges should also be sealed to act as a fire-stop.

This firebox is a universally listed Unvented Firebox Enclosure. For mantel clearances and noncombustible material requirements when installing a decorative type unvented room heater, see page 7. The dimensions noted with “min” are the minimum dimensions that are allowed. Failure to meet the clearance requirements will void your warranty and may result in a fire hazard.

MANTEL CLEARANCES AND NONCOMBUSTIBLE MATERIAL REQUIREMENTS FOR DECORATIVE TYPE UNVENTED

ROOM HEATERS.

Note: The stated installation clearances provide the safest distance for combustible materials to ensure that walls, ceilings, and mantle components will not be affected by heat discoloration, warping, or possible fire. Each appliance installation presents a different set of variables which can create problems beyond the control of the gas log manufacturer. It is the responsibility of the installer to stay within the minimum clearances stated and set forth by the manufacturer within this instruction manual.

The firebox is shipped with a 2 ¾” hood. Loosen screws and slide the hood into place and tighten screws to hold hood.

Heatmaster, LLC. has an optional 4” hood to replace the standard 2 ¾” hood. Contact your local dealer for details.

NOTE: The hood provided with this firebox must not be modified or replaced with another hood or canopy that is not supplied or approved by Heatmaster LLC.

GAS PIPING AND GAS PRESSURE REQUIREMENTS

All gas piping must be installed to comply with local codes or, in the absence of local codes, with the latest edition of the

National Fuel Gas Code ANSI 223.1/NFPA 54.

Unions in gas lines shall be of the ground joint type. Compounds used on threaded joints of gas piping must be resistant to the action of liquefied petroleum gas.

Gas piping must be of sufficient size to provide a minimum natural gas pressure at the appliance of 7” water column or 11” for LP gases. The maximum inlet pressure to the unit must not exceed 10” for natural gas and 13” for LP gases. Manifold pressure for natural gas is 4”WC and 10”WC for LP gas. If this unit is to be supplied with LP gas (bottled propane) the tank or bottle supplying the gas must have a regulator that reduces the gas pressure to between 11 and 13 inches water column.

The control will not operate with gas line pressure directly from the tank and may leak gas due to this excessive pressure.

DANGER: OPERATION OF THIS UNIT ON LP GAS WITHOUT AN APPROVED REGULATOR AT THE SUPPLY

CONTAINER WILL LEAD TO GAS LEAKS AT THE CONTROL WITH POSSIBLE FIRE OR EXPLOSION.

Include a manual shutoff valve and union in the line so the control or heater may be disconnected for servicing. Include a drip leg and a plugged 1/8-inch N.P.T. tapping in the line also. The tapping must be accessible for test gauge connection immediately upstream of the gas supply connection to the unit.

Use a soap-water solution or a liquid gas leak detector to coat each joint in the piping system and look for bubbles, which indicate gas leaks. Repair all gas leaks.

CAUTION: THE LOG SET AND ITS INDIVIDUAL SHUTOFF VALVE MUST BE DISCONNECTED FROM THE GAS

SUPPLY PIPING SYSTEM DURING PRESSURE TESTING OF THAT SYSTEM AT TEST PRESSURES IN EXCESS OF

1/2 PSIG. THE UNIT MUST BE ISOLATED FROM THE GAS SUPPLY PIPING SYSTEM BY CLOSING ITS INDIVIDUAL

MANUAL SHUTOFF VALVE DURING ANY PRESSURE TESTING OF THE GAS SUPPLY PIPING SYSTEM AT TEST

PRESSURES EQUAL TO OR LESS THAN 1/2 PSIG. PRESSURES IN EXCESS OF 1/2 PSIG WILL CAUSE DAMAGE TO

THE CONTROL VALVE AND MAY CAUSE DAMAGE TO THE SHUTOFF VALVE.

DANGER: DO NOT USE CANDLES, MATCHES OR OTHER IGNITION SOURCES WHEN CHECKING FOR LEAKS.

FUEL GASES ARE VERY FLAMMABLE AND, IN CERTAIN CONCENTRATIONS, EXPLOSIVE. CHECKING FOR LEAKS

WITH AN OPEN FLAME MAY LEAD TO FIRE OR EXPLOSION.
