INCONSISTENT FUEL FLOW
Could the presence of
window panes,
uninsulated bulkheads
or degraded insulation
be causing excessive
heat loss?
Has the appliance been
operated for long
enough to raise heat in
the cabin?
It takes time to bring a natural

extremely cold conditions the
time needed to bring an
appliance up to operating
temperatures will be
increased
See page 16
Yes, at least 1-2 hours
No
No
Does the chimney have
less than 4 continuous
