8. PREPARING THE SPACE HEATER
8.1 GUIDELINES OF FUEL GASES - FIG. 1
This heater is intended for the use of temporary
heating of buildings under construction, alteration or
repairing, in accordance with
BSEN449:2002+A1:2007(E). There may also be other
local standards or regulations governing the use of fuel
gases and heating products, of which you can get advice
from your relevant local authority.
Propane and butane belong to the odorless fuel gases
family. Normally gas suppliers will add an odor-making
agent to help you detect a gas leakage. However, the
odor added can fade over time. Fuel gases maybe present even though no odor exists.
These heaters are intended for use with Propane (I3P) or Butane/Propane mixes (I3B/P). Any
other fuel gas is considered misuse and dangerous.
To check the leakage of propane/butane please use a professional gas leakage detector or
simply with soap and water solution. Never check with a flame!
Propane and butane are heavier than air. If there is a leakage, it sinks to the lowest possible
level, collecting there with the surrounding air, forming a potentially explosive mixture. It is
prohibited to use these gas heaters in high rise flats, bedrooms, bathrooms, basements or
below ground level.
8.2 VENTILATION - FIG. 2
WARNING:
Be sure that the heater is only ever used with correct
ventilation. Make sure that no object may obstruct the
fan air intake. (Fig.2.)
OXYGEN DELETION:
The combustion of propane will consume a lot of
oxygen (with butane even more). The minimum
ventilation required by these heaters is 30cm3 per kW
heat output is strongly recommended. Never use the
heater in an enclosed space.
CARBON MONOXIDE (CO) POISIONING:
Even though the direct-fired system of this heater
operates very close to 100% combustion efficiency, it
still generates small amounts of CO. Some people are
more affected by CO than others. The symptoms of CO
sensitivity are headache, dizziness, burning eyes and
nose, nausea, dry mouth or sore throat, etc. Be sure to
follow advice about ventilation.
