Carrier GAS FURNACE 58MTA, Инструкция по установке, запуску и эксплуатации

Страница: 45 / 52

a. Obtain average gas heat value (at installed altitude) from
local gas supplier.
b. Obtain average gas specific gravity from local gas supplier.
c. Verify furnace model and size. Table 10 can only be used
for model 58MTA furnaces with heating inputs of
20,000/13,000 (High/Low) Btuh per burner.
d. Find installation altitude in Table 10.
NOTE: For Canada altitudes of 2001 to 4500 ft, use U.S.A.
altitudes of 2001 to 3000 ft in Table 10.
e. Find closest natural gas heat value and specific gravity on
Table 10.
f. Follow heat value and specific gravity lines to point of
intersection to find orifice size and manifold pressure
settings for proper operation.
