HP SERIES OPERATOR’S MANUAL
Electrical:
This machine, when installed, must be electrically
groundedin accordanceto localcodes.Check for proper
power supply using a volt meter.
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 from walls should be adequate.)
Water Source:
Thewater sourcefor thepressure washershouldbe sup-
plied by a minimum 5/8" I.D.garden hose with a city wa-
ter pressure of not less than 30 PSI. If the water supply
is inadequate, or if the garden hose is kinked, the at-
tached pressure washer will run very rough and the
burner will not fire.
Connection:
See Component Identification on page 7.
Venting:
Adding exhaust vent pipe to your oil fired burner is not
recommended because restricted air flow causes car-
bon build-up, which affects the operation, and increases
maintenance on the coil.If a stack must be used, refrain
fromusing90degreebends.Ifthepipe cannotgostraight
up then use only 45 degree bends and go to the next
size pipe.The overall pipe length must not exceed 6 feet
in length.
