High Altitude Operation
The Trinity is designed to operate at its maximum listed capacity in installations less than or equal to 2000 ft
[610 m] above Sea Level. Since the density of air decreases as elevation increases, maximum specified capacity
should be de-rated for elevations above 2000 ft [610 m] in accordance with Table 2-3.
Table 2-3 De-rate % for High Altitudes
Elevations 2000 ft [610 m] 3000 ft [914 m] 4000 ft [1219 m] 4500 ft [1372 m] 5000 ft [1524 m]
In Canada
1
de-rate by 5% de-rate by 5% de-rate by 5% de-rate by 5% de-rate % may vary
In USA
2
- de-rate by 4% de-rate by 8% - de-rate by 12%
Notes:
1
Canada: Altitudes between 2000-4500 ft [610-1372 m], de-rate by 5%. Consult local authorities for de-rating capacities
for altitudes above 4500 ft [1372 m].
2
USA: De-rate capacity by 4% for every 1000 ft [305 m] over 2000 ft [610 m].
Combustion – At elevations above 2000 feet, the combustion of the appliance must be
checked with a calibrated combustion analyzer to ensure safe and reliable operation. It is
the Installers responsibility
to check the combustion and to adjust the combustion in accordance to
Section 9.0. Failure to follow these instructions may result in property damage, serious injury, or death.
