9.2 Factory Built Fireplaces
The following information applies to Factory Built (metal) Wood-Burning Fireplace installations:
Trim panels must not seal ventilation openings in the replace. Any parts that are removed must be saved and reinstalled if the insert
is ever removed. If the factory-built replace has no gas access hole(s) provided, an access hole of 1 1/2” (38.1 mm) or less may be
drilled through the lower sides or bottom of the rebox in a proper workmanship-like manner. This access hole must be plugged with
noncombustible insulation after the gas supply line has been installed.
The damper (A) and grate with logset (B) must be removed or fully blocked open.
The smoke shelf (C), internal ba󰀪es (D), screen ( E), masonry lining or refractory (G and I), and metal or glass doors (F) may be
removed.
The replace must be permanently marked to indicate that it has been altered and is no longer suitable for burning any fuel unless the
removed parts are reinstalled (See Figure 9.0.02). Cutting out of any metal parts is prohibited, except the metal oor (J) as specied.
The insulation (H), and any structured rigid frame member must not be removed or altered (side and top of door frame, side and top of
the face of replace, metal sides, etc.).
The metal oor of the rebox may be removed only if the following is strictly adhered to.
The metal oor (J) may be removed to allow additional room for installation of the insert as long as it does not compromise the
structural integrity of the existing replace. If the oor is removed the insert must be placed directly on the metal base of the metal
replace. Under no circumstance can it be placed directly on a combustible material.

9.3 Refacing a Masonry Fireplace
Using Steel Studs and Cement Board on Wood Fireplaces
Brick or rock facing may be removed and replaced with noncombustible material such as steel studs and cement board.
WARNING: Only facing material may be removed. All other masonry material must not be cut out, chipped away, or removed.
WARNING: Louvers or any air circulation around existing solid fuel replace must not be blocked or covered.
The area between the masonry and the cement board must be sealed so that no heat can enter the open space between the masonry
of the wood replace and the refacing material. The insert must be moved outward so that the face of the replace is ush with
the nishing material.
Using Steel Studs and Cement Board on Wood Fireplaces
Brick / rock facing may be removed and replaced with non-combustible materials like steel studs and
cement board. Only the facing material can be removed. All other masonry material must not be cut out,
chipped away or removed. The area between the masonry and the cement board, must be sealed so that no
heat can enter the open space between the masonry of the wood fireplace and the re-facing material.
The insert must be pulled out so the face of the fireplace will be flush with the finishing materials.

Installation
11.0 Gas Connections
Before connecting the appliance to the gas supply line, double check that the appliance you have purchased is designed for the
gas type you are using. The gas type markings are located on the rating plate (See Section 4.0 and Section 6.1) and also on the
appliance’s gas valve.
Adequate clearance for proper installation and checking of the gas connections must be provided. All gas connections must be
checked for gas leaks.
Have your gas supplier or a qualied gas tter run a gas supply line into the solid fuel replace. The line must be properly sized and
tted according to the installation codes. Immediately upstream of the supply connection, the tter shall provide an accessible manual
shut-o󰀨 valve. When connecting the supply line to the gas valve, the installer shall brace the gas valve to ensure that the gas valve is
not moved from its bracket. If the valve is not braced when the supply line is connected, the valve may be moved and cause a “break”
in the main burner supply line. Such damage is not covered by the manufacturer’s warranty.
CAUTION: The appliance and its individual shut-o󰀨 valve must be disconnected from the gas supply piping system during any
pressure-testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-o󰀨 valve during any pressure-testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa). Failure to do so will damage the appliance’s gas valve. Such damage is not covered
by the manufacturer’s warranty.
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 5.0” W.C. (1.2 kPa) and a maximum of 14.0" W.C. (3.5 kPa). The orice is a
#44 DMS (2.18 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft (0-1372 M) 15000 - 22,000 BTU/hr (4.4 - 6.45 kW)
4500 ft (1372 M) and above. 15000 - 22,000 BTU/hr (4.4 - 6.45 kW) less 4% per 1000 ft. (305 M) above sea level.
Please contact your local distributor for the appropriate orice size you require.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 12.0” W.C. (2.98 kPa) and a maximum of 14” W.C. (3.5 kPa). The orice is a
#54 DMS (1.397 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 17,000 - 22,000 BTU/hr (4.98 - 6.45 kW)
4500 ft. (1372 M) and above. 17,000 - 22,000 BTU/hr (4.98 - 6.45 kW) less 4% per 1000 ft. (305 M) above sea level.
Please contact your local distributor for the appropriate orice size you require.
11.1 Clocking Procedure
IMPORTANT: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST FIRING THIS APPLIANCE.
Before you begin, shut o󰀨 all other gas appliances including any standing pilots. Light the replace and wait 15 minutes. Clock the
time to burn 1ft³ of gas on the meter. Check with your gas supplier for the gas BTU content at your elevation. Input is the rate of ow
multiplied by the heating value of the gas (cubic feet/hour x BTU per cubic feet). Note: This assumes a dry gas meter at 1/2 psi. If using
a 2 psi dry gas meter the unit will rate lower as the calculation has to correct for the higher pressure in the meter. If the unit is over-
rated, contact your authorized Archgard dealer. The following calculation equation gives a rough estimation as it does not correct for
temperature and pressure.
Rough Calculation Equation:
1 / Time to burn 1ft³ of gas in seconds / 3600 x gas caloric value in BTU/ft³ = Rating

12.0 Conversion Kit Instructions
IMPORTANT: This replace is Natural gas ready. If converting to LP gas, follow instructions below.
WARNING: This conversion kit shall be installed by a qualied service agency in accordance with the manufacturers instructions
and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed
exactly, a re, explosion or productions of carbon monoxide may result, causing property damage, personal injury or loss of life. The
qualied service agency is responsible for proper installation of this kit. The installation is not proper and complete until operation
of the converted appliance is checked as specied in the instructions supplied with the kit. Refer to appliance owner’s manual or
product data plate for proper inlet and manifold pressure adjustments and orice sizing.
IMPORTANT: For high altitude installations above 4500 ft (1372 meters), consult local gas distributor or the authority having
jurisdiction for proper derating methods.

12.1 Prepare the Fireplace
Remove the surround, barrier screen, glass frame assembly, logs or glass media, embers and brick panels or rebox liner (if
applicable)*.
Remove the burner*.
*See relevant sections in this manual.
Remove the burner orice using a 3/8” wrench. Replace with the orice supplied with the
conversion kit. Use a small amount of pipe sealant on the threads of the orice mount. Do not
use too much as it can block the orice.
Figure 12.1.01:
WARNING: Installation should be carried out in a clean environment.
WARNING: This modulating conversion kit must ONLY be applied as part of a conversion kit supplied by the APPLIANCE
MANUFACTURER.
WARNING: Correct operation of the system cannot be guaranteed if the conversion kit or valve has been dropped or has
sustained a strong impact.
INSTALLER NOTICE: These instructions must be left with appliance.
