SECTION 3: CRITICAL CONSIDERATIONS

WARNING
Fire Hazard
Keep all flammable objects, liquids and
vapours the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.

3.1 Basic Information

Cabinet heaters are supplied with burners suitable
for on/off operation as standard. As an option, two-
stage (High/Low) operation is available for gas and
oil-fired burners.

3.2 Location and Suspension

All models:
• Must be installed indoors within the heated
space. Special versions are available for installa-
tion outdoors.
• Must be installed for floor standing vertical
installation.
• Must be installed in a manner which allows all
the upper panels and either of the lower side
panels to be removed to provide access to all
serviceable components.
• Must be placed on a firm, level, non-combustible
surface that can support its weight. See Page 8,
Section 4.1 for weight details.
• Special versions supplied with steel channels to
support the heater are available and may be
mounted horizontally. When installed horizon-
tally, the heater will normally lie on its left side
when viewed from the burner. The same clear-
ances and comments on panels must be used,
except for the side the heater lies on.

3.3 Required Clearances to Combustibles

Clearances are the required distances that
combustible objects must be away from the heater
to prevent fire hazards. Caution should be used
when running the system near combustibles.
Combustibles are materials, which may catch on fire
and include common items such as wood, paper,
rubber, fabric, etc. Maintain clearances to
combustibles at all times for safety.
Clearances around the heater and flue must be as
indicated on Page 6, Figure 2 to ensure access for
servicing, and correct operation. If clearances to
SECTION 3: C
combustibles are not indicated, then installation
clearances apply.
Check the clearances on each heater for the model
heater being installed to make sure the product is
suitable for your application and the clearances are
maintained. Read and follow the safety guidelines
below:
• Keep petrol or other combustible materials
including flammable objects, liquids, dust or
vapours away from this heater or any other appli-
ance.
• Do not spray aerosols in the vicinity of this appli-
ance.
• The stated clearances to combustibles repre-
sents a surface temperature of 50° C (90° F)
above room temperature. Building materials with
a low heat tolerance (such as plastics, vinyl sid-
ing, canvas, tri-ply, etc) may be subject to degra-
dation at lower temperatures. It is the installer's
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive equip-
ment and workstations.
• Maintain clearances from vehicles parked below
the heater.
• Maintain clearances from swinging and over-
head doors, overhead cranes, vehicle lifts, parti-
tions, storage racks, hoists, building
construction, etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to main-
tain required clearances from the heater to the
combustibles. Signs must be posted adjacent to
the heater thermostat. In the absence of a ther-
mostat, signs must be posted in a conspicuous
location.
• Consult local Building Inspector, Fire Insurance
Carrier or other authorities for approval of pro-
posed installation when there is a possibility of
exposure to combustible airborne materials or
vapours.
• Hang heater in accordance to minimum suspen-
sion requirements. Consult manufacturer.
• Affix the tag on a wall near the heater.
