..
few quick checks of your M17
before you operate are the first steps
on the path to good deconning.
Heat exhaust ports
—Are ports clear
of leaves and dirt? If the ports are
clogged, you have a fire hazard. Even
if the ports are clear, stand away from
them when starting the heater. Flames
can shoot out of the ports.
Water inlet and outlet valves
—
Over time, sediment and rust build up
in the ports of the quick disconnects
and block water flow in and out of the
M17. That strains the water pump and
eventually kills it. Run your wire brush
through the ports to break up the sedi-
ment and flush out the system with
clean water.
M17 is hot when the engine shuts
down, the water heater is damaged be-
cause it hasn’t cooled down properly.
Fix a loose throttle by tightening its
locking machine screw. If the throttle
responds poorly when you move it, re-
port loose linkage.
Filters
—The fuel and water lines,
engine, and burner all have filters. If
they’re dirty,
they clog and
your M17 has
trouble
drawing fuel
or water.
If dirt has
accumulated in
the burner
filter, drain it
out. Clean the
fuel can filter
with your
fingers or a
toothbrush.
Get the engine
fuel filter
replaced if it’s
clogged. Clean
the water
suction hose
and branch
hose filter
with your wire
brush.
