High Altitude Adjustment
When installing GI 450 Katahdin insert at high altitude
(above 2000'), it is necessary to compensate for the
thinner air (less volume of air per cubic foot). Higher
altitudes affect the atmospheric pressure and heat
value of gaseous fuels. The lower oxygen content in the
air and the lower gas viscosity require the use of a
different orifice to achieve efficient, clean combustion
at the burner tube.

This unit has been tested for installation at high alti-
tudes 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.
HIGH ALTITUDE INSTALLATIONS:
2000 ft. to 4500 ft. installations (or 610m - 1370m)
See Table 1.
For high altitude installations consult the local gas
distributor or the authority having jurisdiction for
proper rating methods. If the installer must convert the
unit to adjust for varying altitudes, the information label
must be completed by the installer and affixed to the
appliance at the time of the conversion. See fig. 14.
Derating procedure
