Converting Between Fuels

Conversion of a unit between natural gas and propane requires
replacement of the orifice. This procedure must be performed
by an authorized and certified gas equipment installer.
NOTE: After converting from one type of fuel to another, the
spring in the pressure regulator must be changed
to correspond with the gas pressure. A Spring Kit is
included with the unit that contains a spring, installation
instructions, and a spring identification label.
Turn Temperature Controls to OFF position, close gas
shut-off valve, and allow unit to cool before performing any
cleaning, adjustments, or maintenance.
FIRE OR EXPLOSION HAZARD: This unit must be serviced
by qualified personnel only. Service by unqualified
personnel may lead to explosion or burn.
1. If the unit already has been installed, turn both
Temperature Controls fully clockwise to the
"Off" position, and close the gas shut-off valve.
WARNING! Always close gas shut-off valve
when unit is not in use.
