Gas Setup and Information
A.
Fuel Type
Before making any gas connections, ensure that the
appliance being installed is compatible with the
available gas type.
This appliance comes setup for a specific gas type from
the manufacturer.
Field conversion from one gas type
to another is not recommended.
WARNING:
FIRE AND EXPLOSION RISK
VERIFY INLET PRESSURES
High pressure may cause an over-fire condition.
Low pressure may cause delayed ignition and
explosion.
Minimum pressures must be verified when ALL
household appliances are operating.
AN APPLIANCE REGULATOR MUST BE INSTALLED
UPSTREAM OF THE APPLIANCE FOR ALL PRESSURES
ABOVE 14 IN. WC FOR LIQUID PROPANE AND ALL
PRESSURES ABOVE 11 IN. WC FOR NATURAL GAS.
B. Gas Pressure
Proper input pressures are required for optimum
performance and safety. Gas line sizing is
extremely
important and should be performed only by a qualified gas
professional. Supply line sizing requirements need to be
made following ANSI Z223.1/NFPA 54.
Pressure requirements for the appliance are shown in the
table above and to the right. Pressure readings must be
attained
WHILE THIS APPLIANCE AND ALL OTHER GAS
APPLIANCES ARE IN OPERATION.
Although it is safe to operate at minimum pressure, the
unit should be operating at ideal inlet pressure, shown in
the table above and to the right.
C.
Gas Supply and
Connection
All fixed fuel piping (hard-piped) systems shall be
installed in accordance to local building codes, if none
exist ANSI Z223.1/NFPA 54 should be followed.
Installation of fixed fuel piping (hard-piped) systems
should be performed
only by authorized installers
approved and/or licensed as required by the locality.
A dedicated manual shut-off valve shall be
installed upstream of this appliance and its
controls.
This appliance and its dedicated manual shutoff
valve need to be disconnected from the main
gas supply system during any pressure testing in
excess of ½ psi (3.5 kPa).
This appliance must be isolated from the main
gas supply by closing its dedicated manual
shutoff valve during any pressure testing of the
gas supply system at test pressures equal to or
less than ½ psi (3.5 kPa).
