Gas Pressure

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.)

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).

High Altitude Adjustment

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.
