Operations
Draft Diverter
A draft diverter should be installed
above the heating coil. The
diverter serves to sever the
chimney effect created in all
sections of furnace pipe positioned
below to enhance the draft through
the burner. It also helps prevent
freezing of the coil due to wind chill
factors.
NOTE: The draft diverter is not standard on VHP
machines.
When the pressure washer is installed in a tightly
closed room without ventilation openings to the
outdoors or other rooms, provisions shall be made for
supplying air for combustion through special openings,
one near the floor line and the other near the ceiling,
each to be sized on the basis of one square inch or
more of free area for each 1,000 BTU input per hour.
Placement
Do not locate near any combustible material. Keep all
flammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from floor and
walls. (Two feet away should be adequate.)
Water Source
Water source for machine should be supplied by a 5/8"
I.D. garden hose with a city water pressure of not less
than 30 psi. If the water supply is inadequate, or if the
garden hose is kinked, the machine will run very rough
and the burner will not fire.
Connection
Connect the wand, nozzle, hose and spray gun (where
applicable). On pipe thread connections, use teflon
tape to avoid water leaks. (See Component Identifica-
tion.)
Attach high pressure hose to discharge nipple by
pulling the quick coupler collar back and inserting it
onto the discharge nipple. Then push the collar forward
to secure. A detergent injector could be inserted
between the hose coupler and the discharge nipple.

Place detergent dip tube into liquid soap or detergent
solution. Avoid letting tube suck air.
CAUTION: When installing propane hose to LP
tank, please note that it has left hand threads.
ATTENTION: Au moment de l'installation du tuyau
de propane au réservoir de pétrole liquide, veuillez
prendre note que ce dernier est muni de raccords

Inspection and Testing
Before turning gas under pressure into piping, all
openings from which gas can escape should be closed.
Immediately after turning on gas, the system should be
checked for leaks. This can be done by watching the 1/
2 cubic foot test dial and allowing 5 minutes to show
any movement, or by soaping each pipe connection
and watching for bubbles. If a leak is found, make the
necessary repairs and repeat the above test.
Defective pipes or fittings should be replaced and not
repaired. Never use a flame or fire in any form to locate
gas leaks, use a soap solution.
After the piping and meter have been checked
completely, purge the system of air. DO NOT bleed the
air inside an enclosed room.
The pressure washer and its individual shut-off valve
must be disconnected from the gas supply piping
system during the pressure testing of that system at
test pressure in excess of 1/2 psig or damage to the
gas valve will occur.
Shut-Off Valve
A gas shut-off valve has been installed between the
gas supply line and the washer. The plumbing also
includes a union between the shut-off valve and the
burner.
Condensation from Coils
When cold water is being pumped into the water heater
coils, and the burners are on, condensation will form on
the coils and drip down into the burner compartment
giving the appearance of a leaking coil, particularly on
cold humid days.
