D. High Altitude Installations
NOTICE: If the heating value of the gas has been reduced,
these rules do not apply. Check with your local gas utility
or authorities having jurisdiction.
When installing above 2000 feet elevation:
• In the USA: Reduce input rate 4% for each 1000 feet
above 2000 feet.
• In CANADA: Input ratings are certified without a
reduction of input rate for elevations up to 4500 feet
(1370 m)above sea level. Please consult provincial and/
or local authorities having jurisdiction for installations at
elevations above 4500 feet (1370 m).
Check with your local gas utility to determine proper
orifice size.
E. Air Shutter Setting
WARNING! Risk of Explosion or Delayed Ignition!
Improperly adjusted air shutter could cause soot buildup.
