C. Gas Pressure Requirements
Pressure requirements for VRT-AUB fireplaces are shown
in table below.
Two taps are provided on the right hand side of the gas
control for a test gauge connection to measure the inlet and
outlet pressures.
MODELS:
VRT-AUB
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 certification 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. Additional Related Standards
The installation must comply with these installation instructions
and all relevant parts of Local and National Building
Standards Regulations and those relevant recommendations
of the following British Standards. BS 5871: Part 1 BS 8303
BS 5440: Parts 1 & 2 BS 6891 BSEN1856 Parts 1 & 2 BS
5482 Part 1, as well as IGE/UP/7.
The fireplace and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of the system at test pressures in excess
of 6 kPa.
If the fireplace must be isolated from the gas supply piping
system by closing an individual shut-off valve, it must be of
the handle-less type.
WARNING! Risk of Explosion!
An in-line regulator MUST
be installed if the gas pressure exceeds 3.7 kPa. Failure to
install a regulator could damage valve.
D. 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.
E. Non-Combustible Materials Specification
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 (1832 ºF)
and
UL763
shall be considered non-combustible materials.
F. Combustible Materials Specification
Materials made of or surfaced with wood, compressed paper,
plant fibers, plastics, or other material that can ignite and burn,
whether flame proofed or not, or plastered or unplastered
shall be considered combustible materials.
G. Electrical Codes
All electrical safety testing has been done following the EN
60335-2-102 standard. Local codes apply.
