AS UPPLY
NOTICE: A qualified technician must connect the
heater to the gas supply and leak test the unit before
it is approved for use. Consult all codes.
WARNING: THE UNIT MUST BE INSTALLED
AND CONNECTED IN ACCORDANCE WITH LOCAL
CODES, OR IN THE ABSENCE OF LOCAL CODES,
WITH THE MOST CURRENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1 (NFPA
54) OR CAN/CGA B149 INSTALLATION CODE.
NFPA Code and Hearthstone require the use of a
dedicated sediment trap just upstream of the unit.
Damage to the valve or other components, due to the
lack of a sediment trap
warranty.
G C
AS ONNECTIONS
The gas supply connection is made to the Luno's gas control
valve at the middle, lower rear of the stove, using a 3/8"
male NPT fitting. The supply line should be ½" diameter, or
appropriately sized to provide a sufficient gas supply to
meet the maximum demand of the unit without undue loss
of pressure. We recommend a flexible line to avoid undue
mechanical load on the valve and to ease thread alignment,
but refer to local codes.
CAUTION: Check Gas Type!
G S
AS UPPLY
Isolate the Luno from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or greater than ½ psig. Disconnect the

Luno and its individual shut-off valve from the piping system
when testing the valve and connections at pressures equal
to, or greater than ½ psig.

AS RESSURE
NOTE: A QUALIFIED TECHNICIAN MUST
PERFORM THIS PROCEDURE!
Once connected to the gas supply, the supply line and
manifold gas pressures must be tested. The supply line
pressure is tested, to ensure it meets the minimum gas
supply pressure as listed in the Specifications for the type of
fuel in use (natural gas or LP), by connecting a manometer
to the supply line and adjusting the incoming pressure if
necessary to meet the required supply line pressure as listed
in specifications. The manifold pressure tap on the gas
control valve, refer to
