NOTE:
Observing frost on LPG
is common during operation and normally is not
an indication of a problem. As LPG vaporizes and
travels from the tank to the generator engine it
expands. The amount of frost that forms can be
affected by the size of the cylinder, the amount
of fuel being used, the humidity of the air and other
operating conditions. In unusual situations this
frost may eventually restrict the flow of LPG gas
to the generator resulting in deteriorating
performance. For example, if the tank temperature
is reduced to a very low level then the rate at which
the LPG vaporizes is also reduced and may not
provide sufficient fuel flow to the engine. This is
not an indication of a problem with the generator
but only a problem with the flow of gas from the
LPG cylinder. If generator performance seems
to be deteriorating at the same time that ice
formation is observed on tank valve, hose or
regulator then some actions may be taken to
eliminate this symptom. In these rare situations
it can be helpful to reduce or eliminate the cold
fuel system effects by doing one of the following:
•
Exchanging fuel tanks to allow the first tank
to warm up, repeating as necessary
•
Placing the LPG cylinder at the end of the
generator near the handle, where engine fan
air flows out from the generator. This air is
slightly heated by flowing over the engine.
DANGER
DO NOT PLACE THE LPG CYLINDER IN THE PATH
OF MUFFLER OUTLET.

The LPG cylinder can be temporarily warmed
by pouring warm water over the top of the
cylinder.
