Correct gas pressure is essential for efficient and safe
operation of the Nordic QT gas stove.  It is important that
the correct pressure is established at the time of the
installation.  Proper gas pressure provides a consistent
flow of gas to the appliance and is instrumental in
checking for gas leaks.

Pressure Test:  Attach a manometer to the appropri-

ate test point on the valve. See fig. 20. The gauge connec-
tions are located on the front of the valve under the On/
Off/Pilot- knob.  Gauge connections are identified by:

E -    for Inlet or Supply Pressure (the amount of gas

coming to the valve.)

A -   for Manifold Pressure (the amount of gas that is

coming out of the valve to the burner.)

Higher altitudes affect the atmospheric pressure and
heat value of gaseous fuels.  When installing the Nordic
QT in high altitude (above 2500'), it will be necessary to
compensate for the thinner air (less volume of oxygen
per cubic foot). The lower oxygen content in the air and
the lower gas viscosity require the use of a different
orifice to achieve efficient combustion.

IN THE U.S:

THE DERATING KIT MUST BE INSTALLED BY

AN AUTHORIZED SERVICE TECHNICIAN IN

ACCORDANCE WITH THE MANUFACTURER’S

INSTRUCTIONS AND ALL CODES AND RE-

QUIREMENTS OF THE AUTHORITY HAVING

JURISDICTION.  THE INFORMATION STICKER

MUST BE FILLED OUT BY THE INSTALLER

AND ADHERED TO THE APPLIANCE AT THE

TIME OF THE CONVERSION. THE QUALIFIED

SERVICE AGENCY PERFORMING THIS WORK

ASSUMES RESPONSIBILITY FOR THIS DERAT-

ING.

IN CANADA,
THIS UNIT HAS BEEN TESTED FOR INSTALLA-

TION AT HIGH ALTITUDES IN ACCORDANCE

WITH CANADIAN TEST STANDARD CAN/CGA-

2.17.
THE DERATING SHALL BE CARRIED OUT IN

ACCORDANCE WITH THE REQUIREMENTS OF

THE PROVINCIAL AUTHORITIES HAVING

JURISDICTION AND IN ACCORDANCE WITH

THE REQUIREMENTS OF THE CAN1-B-149.1

AND .2 INSTALLATION CODE.

For installations from 610 - 370 meters (2000-4500

ft.) The orifice size for natural gas is #49 and for propane
gas #60. See the chart below

For high altitude installations, consult your local gas

distributor or the authority having jurisdiction for proper
rating methods. If the appliance is converted for high
altitude, the Conversion Label must be filled out by the
installer and applied to the appliance at the time of the
conversion.

The appliance and its appliance main gas valve must

be disconnected from the gas supply piping system
during any pressure testing on that system at test
pressures in excess of 1/2 psig (3.5 kPa).

The appliance must be isolated from the gas supply

line by closing its individual manual gas shut-off valve
(gas cock) during any pressure testing of the gas supply
piping system that is equal to or exceeds pressures of 1/
2 psig (3.5 kPa).
