SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Requ
ired Clearances to Combustibles
Clearances are the requi
red 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 3 to ensur
e access for
servi
cing, and correct operation. If clearances to
combustibles are not indicated, then installation
clearances apply.
Check the clearances on each bur
ner 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 combus
tible materials
including flammable objects, liquids, dust or
vapours away from this heater or any other appli-
ance.
• The stated clearances to combust
ibles rep-
resents a surf
ace temperature of 32°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 t
emperatures. It is the installer’s
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive e
quip-
ment and w or
kstations.
• Maintain clearances from vehi
cles parked below
the heater.
• Maintain clearances from swi
nging and over-
head doors, overhe
ad cranes, vehicle lifts, parti-
tions, storage racks, hoists, build
ing
construction, etc.
• In locations us
ed for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to main-
tain requi
red clearances from the heater to the
combustibles. Signs must be posted adjacent to
the heater thermostat. In the absence of a ther-
mostat, signs mus
t be posted in a conspicuous
location.
• Consult
local Building Inspector, Fire Insurance
Carrier or other authorities for approval of pro-
posed installation when t
here is a possibility of
exposure to combustible airborne materials or
vapours.
• Hang heater in accordance to the minimum
suspension requirements on Page 12, Section 6
and Page 13, Figure 4.
• Affix the tag on a w al
l near the heater.
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.
