Shut Down Instructions



Appliance is only to be serviced or repaired
by an authorised service centre. Return
appliance to place of purchase or contact
Primus Customer Service (contact details
on back cover).

Always keep the heater area clear and free
from combustible materials, gasoline and other
ammable vapors and liquids.

Keep the vent areas (slots in the bottom and
the top at the front and rear of heater) clear at
all times.

Visually inspect the pilot ame and burner
periodically during use. The pilot ame should
be blue in color (not yellow) and will extend
beyond the thermocouple.

The ame will surround the thermocouple just
below the tip.

A slight yellow ame may occur where the pilot
ame and main burner ame meet. The burner
should be bright orange (with a slight blue color
around the border, a red-orange haze that is
visible on the ceramic tile is acceptable) and
without a noticeable ame. A blue ame that
rolls out at the top of the ceramic tile indicates
an accumulation of dust, lint or spider webs
inside the casing assembly and main burner
assembly. If the pilot is yellow or the burner has
a noticeable ame, cleaning may be required.
Use the following procedure to inspect the
casing assembly and main burner assembly.
