Listing and Code Approvals

A. Appliance Certifi cation
MODELS: COSMO-I30AU
LABORATORY: SAI Global
TYPE: Gas Space Heating Appliance
STANDARD: AS4553-2008
The Heat & Glo gas appliances discussed in this Installer's
Guide have been tested to certifi cation standards and listed
by the applicable laboratories.
This appliance must be installed in accordance with the
rules in force.
NOX Class 5 for G20, NOX Class 5 for G31
B. Gas Pressure Requirements
WARNING! Risk of Explosion! An in-line regulator
MUST be installed if the gas pressure exceeds 3.4 kPa.
Failure to install a regulator could damage valve.
Pressure requirements for Cosmo-I30AU natural gas
and propane gas fi replaces are shown in table below.
Two taps are provided on the front of the gas control for
a test gauge connection to measure the inlet and outlet
pressures.
The fi replace and its individual shut-off valve must be dis-
connected from the gas supply piping system during any
pressure testing of the system at test pressures in excess
of 60 mbar or 6 kPa.
If the fi replace must be isolated from the gas supply pip-
ing system by closing an individual shut-off valve, it must
be of the handle-less type.
Inlet Gas Pressure
Outlet (Manifold) Gas Pressure
Maximum Gas Consumption
Burner Injector
Pilot Injector
An in-line regulator MUST be installed if the gas pressure exceeds 3.40 kPa. Failure to install a regulator could damage
valve.

C. High Altitude Installations
NOTICE: If the heating value of the gas has been reduced,
these rules do not apply. Check with your local gas utility
or authorities having jurisdiction.
When installing above 610 meter elevation:
Reduce input rate 4% for each 305 meters feet above
610 meters.
D. Non-Combustible Materials Specifi cation
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in
a Vertical Tube Furnace at 750 ºC shall be considered
non-combustible materials.
E. Combustible Materials Specifi cation
Materials made of or surfaced with wood, compressed pa-
per, plant fi bers, plastics, or other material that can ignite
and burn, whether fl ame proofed or not, or plastered or
unplastered shall be considered combustible materials.
F. Electrical Codes
All electrical safety testing has been done following the EN
60335-2-102 standard. Local codes apply.
