High Altitude Adjustment - Jøtul GF 400 BV Sebago Installation And Operation Instructions Manual

High Altitude Adjustment

Installations burning natural gas and located at altitudes
from 2000 - 4500 ft. (610 M - 1370 M), require compensa-
tion 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.
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, use Jøtul High Altitude Kit,
#155885-LP or # 155895 NG.
