A. Fuel Conversion
• Make sure the appliance is compatible with available gas
types.
• The Palazzo series gas appliance is supplied from
the factory for use with natural gas. If a propane (LP)
conversion is required, kit LPK-ODPALG-48 must be
purchased in order to convert the unit for use with
propane.
• Conversions must be made by a qualified service
technician using Hearth & Home Technologies specified
and approved parts.
B. Gas Pressure
• Optimum appliance performance requires proper input
pressures.
• Gas line sizing requirements will be determined in ANSI
Z223.1 National Fuel Gas Code in the USA and CAN/
CGA B149 in Canada.
• Pressure requirements are:
C. Gas Connection
• Refer to Reference Section 3 for location of gas line
access in appliance.
Note:
The Palazzo is supplied with two rubber grommets
installed on the left side of the appliance for gas and
electrical connections. A cover plate is also provided on
the right side of the appliance in the event that gas and
electrical must be run from the right. If it is determined
that gas and electrical are to be run through the right
side of the appliance, the grommets and cover plates
must be repositioned. See Figure 6.1.
• The gap between supply piping and gas access hole
may be caulked with caulk with a minimum of 300ºF
continuous exposure rating or stuffed with non-
combustible, unfaced insulation to help prevent rodents
and insects from getting into the control area of the
appliance.
• Ensure that gas line does not come in contact with outer
wrap of the appliance. Follow local codes.
• Verify inlet pressures. Verify minimum pressures when
other household gas appliances are operating.
• Install regulator upstream of valve if line pressure is greater
than 1/2 psig.

Fire Risk.
Explosion Hazard.
High pressure will damage valve. Low
pressure could cause explosion.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 1/2 psig.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 1/2 psig.
wARNING
These pressures can be verified through the access
panel as shown in Section 6.D Valve Access.
When an appliance is connected to a fixed piping sys-
tem, the installation must conform with local codes, or in
the absence of local codes with the
National Fuel Gas
Code, ANSI Z223.1/NFPA 54, or International Fuel Gas
Code.
Note:
Have the gas supply line installed in accordance with
local codes, if any. If not, follow ANSI 223.1. Installation
should be done by a qualified installer approved and/or
licensed as required by the locality. (In the Commonwealth
of Massachusetts installation must be performed by a
licensed plumber or gas fitter).
Note:
A listed (and Commonwealth of Massachusetts ap-
proved) 1/2 in. (13 mm) T-handle manual shut-off valve
and flexible gas connector are connected to the 1/2 in. (13
mm) control valve inlet.
• If substituting for these components, please consult
local codes for compliance.
Note:
An individual manual shutoff valve (not supplied) is
required when installing this appliance. The manual shutoff
valve must be located in an easily accessible area, no more
than 6 feet from the appliance.
