LP Vapor Fuel
The model 558 has been factory built to use LP vapor
fuel.
DO NOT use liquid fuel.
NE PAS utiliser de
carburant liquide.
Have a qualified gas serviceman install the LP vapor
fuel supply line to the machine. See below for location of
gas inlet.
Gas Regulator
It is very important that the incoming gas pressure be
between 12.0-14.0 water column inches (.43-.50 PSI).
If your fuel supply does not produce the correct
pressure range contact your local Hotsy Service Repre-
sentative.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set for elevations of
0 to 2000 ft. Altitudes greater than 2000 ft will require
adjustments to the gas manifold pressures. Consult
your local service dealer for high altitude adjustments.
In Canada, certification for installation at altitudes over
4500 feet above sea level is the jurisdiction of local
authorities. You should not readjust the burner ring gas
pressure. If you replace your gas valve, you will need to
adjust the new valve. Refer to your machine’s
specifi-
cation plate
for the correct pressure setting. Follow the
installation and adjustment instructions provided with
your replacement valve.
NOTE: Air for combustion and ventilation along with
exhaust flue sizing must conform to methods outlined
in current American Standard (ANSI-Z223.1) National
Fuel Gas Code or National Standard of Canada CSA-
149.1 and CSA-149.2 “Installation Code for Gas
Burning Appliances”.

IMPORTANT: All wiring must be of proper voltage
and amperage rating and conform to applicable
codes.
IMPORTANT: This machine must be electrically
grounded. LA MACHINE DOIT ÊTRE MISE À LA
TERRE.
Grounding Instructions:
Make sure all switches and
controls are in the OFF position prior to connecting
electrical supply. Do not stand in water while
connecting and disconnecting electrical supply. If it
should malfunction or break down, grounding provides
a path of least resistance for electric current to reduce
the risk of electric shock. The product must be
connected to an appropriate power source that is
properly installed and grounded in accordance with all
local codes and ordinances.
DANGER: Improper connection of the equipment
grounding conductor can result in a risk of electro-
cution. Check with a qualified electrician or service
