Installation
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 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
#43 DMS (2.25mm) drill size.
ELEVATION INPUT RATING
0-4500 ft (0-1372 M) 22,400 BTU/hr (9.6 kW)
4500 ft (1372 M) and above. 22,400 BTU/hr (9.6 kW) less 4% per 1000 ft. (305 M)
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 11.0” W.C. (2.8 kPa) and a maximum of 14.0” W.C. (3.5 kPa). The orice is a
#54 DMS (1.36 mm) drill size.
ELEVATION INPUT RATING
0-4500 ft. (0-1372 M) 21,000 BTU/hr (9.02 kW)
4500 ft. (1372 M) and above. 21,000 BTU/hr (9.02 kW) less 4% per 1000 ft. (305 M)
Please contact your local distributor for the appropriate orice size you require.
To do this, reduce the background ow rate, time the meter.
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

Masonry chimneys may take various contours which the exible liner will accommodate, however, keep the exible liner as straight as
possible, avoiding unnecessary bending but at all times keep a minimum of 3” (76 mm) inside bend radius.
The Air Intake Flex Liner must be connected to the inlet air collars of the termination cap and the appliance.
The Exhaust Flex Liner must be connected to the exhaust collars of the termination cap and the appliance.
The Air intake and Exhaust connections are marked on the gas appliance. See Figure 13.0.01.
DO NOT REVERSE THESE CONNECTIONS
CAUTION
To ensure that the venting is not accidentally obstructed or punctured, the damper of the host replace must be permanently disabled

Sealing the Vent
Secure the exible liner at the top of the replace and at the termination. DO NOT use silicone as this will void the ame sensor
warranty. Use mil-pac or other non silicone sealant and three (3) screws or gear clamps to seal the liner at each end.
