• Photographing the installation and copying this checklist for your le.
• That this checklist remain visible at all times on the appliance until the installation is complete.
This standard work checklist is to be used by the installer in conjunction with, not instead of, the instructions contained in this
installation manual.
WARNING! Risk of Fire or Explosion! Failure to install appliance according to these instructions could
lead to a re or explosion. Install ONLY components and accessories approved by Hearth & Home
Technologies. Upapproved components and accessories could cause appliance to overheat.
ATTENTION INSTALLER:
Follow this Standard Work Checklist

A. Appliance Certication
NOT INTENDED FOR USE AS A PRIMARY HEAT SOURCE.
This appliance is tested and approved as either supplemen-
tal room heat or as a decorative appliance. It should not be
factored as primary heat in residential heating calculations.
11 Product Specic and Important Safety Information
C. Gas Pressure Requirements
Pressure requirements for B41L-AU replaces 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.
The 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 3.4 kPa.
If the 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.
MODEL: B41L-AU
LABORATORY: IAPMO OCEANA
TYPE: Direct Vent Heater
STANDARD: AS/NZS 5263.1.8
The Hearth & Home Technologies gas appliances discussed
in this Installer’s Guide have been tested to certication
standards and listed by the applicable laboratories.
This appliance must be installed in accordance with the AS/
NZS 5601.1 rules in force.
Gas types only through eld conversions.
* The allowable Outlet (Manifold) Gas Pressure ranges are: Natural Gas 0.63 - 0.95 kPa (0.76 kPa nominal) and Propane
2.37 - 2.61 kPa (2.40 kPa nominal). Certication testing setpoint values are shown.
NOTE: An inline fuel pressure regulator is recom-
mended to limit NG inlet pressure to 2.49 kPa, and
Propane inlet pressure to 3.25 kPa, to ensure optimum
product performance. The inline fuel pressure regula-
tor may be needed if any of the following symptoms
exist: pilot jetting, a highly visible pilot ame, ame
variation, etc. The inline pressure regulator should
be installed in the gas line upstream of the appliance
gas valve either at the appliance or in the utility room.
Final main and manifold gas pressure must be tested
with inline pressure regulator installed.
Natural Gas Propane
Inlet Gas Pressure 1.13 - 3.40 kPa 2.75 - 3.40 kPa
* Outlet (Manifold) Gas Pressure 0.76 kPa 2.40 kPa
Nominal Gas Consumption 20.0 MJ/h 20.0 MJ/h
Burner Injector #44 DMS (2.18 mm) #55 DMS (1.32 mm)
Pilot Injector Ø .023 (.584 mm) Ø .014 (.356 mm)
B. Glass Specications
Hearth & Home Technologies appliances manufactured
with tempered glass may be installed in hazardous lo-
cations such as bathtub enclosures as dened by the
Consumer Product Safety Commission (CPSC). The
tempered glass has been tested and certied to the re-
quirements of ANSI Z97.1 and CPSC 16 CFR 1202
(Safety Glazing Certication Council SGCC# 1595 and
1597. Architectural Testing, Inc. Reports 02-31919.01
and 02-31917.01).

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 2000 ft. (610 m) elevation:
Reduce input rate 4% for each 1000 ft. (305 m) above
2000 ft. (610 m).
E. Non-Combustible Materials Speci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 (1382 °F) shall be con-
sidered non-combustible materials.
F. Combustible Materials Specication
Materials made of or surfaced with wood, compressed pa-
per, plant bers, plastics, or other material that can ignite
and burn, whether ame 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.
