LP GAS
LP Gas is a manufactured gas that has
consistent heating value across most
regions.
The NFGC guidelines are used with the
following exception:
The recommended LP Gas high altitude
orifice selections differ slightly in that the
NFGC LP orifice chart, as they are not
accurate for ICECO products. The
National Fuel Gas Code LP orifices are
based on an 11" of water column
pressure at the orifice, which differs from
ICECO products that use 10" of water
column at the orifice. This difference
requires a deviation from the NFGC
orifice size recommendations. The Sea
Level input should still be reduced by 4%
per thousand ft. and the orifice size must
be selected based on the reduced input
selection chart below.
ORIFICE ORDERING
INFORMATION
Orifice sizes are selected by adding the
2-digit drill size required in the orifice
part number. Drill sizes available are 39
through 64; metric sizes available
1.10mm (-90) and 1.15mm (-91):
Orifice Part Number 62-22175-(drill
size)
Example 1:
# 60 drill size orifice required
Part # 62-22175-60
Example 2:
1.15mm drill size orifice required
Part # 62-22175-91.
ALTERNATE METHOD FOR
CANADIAN
HIGH-ALTITUDE
DERATE
In Canada, unless an orifice change is
specifically mandated by local codes,
an alternate method of altitude deration
through a reduction in manifold
pressure is acceptable as described in
Table 7. This information is based on a
heating value of 1000 BTU per cubic
feet of natural gas, and 2500 BTU per
cubic feet of LP gas.
IMPORTANT: Actual input rates must
be measured onsite with manifold
pressure adjustment to ensure that an
actual 10% reduction in input rate is
achieved.
Once this field adjustment has been
made, the label shown in Figure 18
rmust be affixed in a conspicuous
location on the front of the furnace
cabinet.
NOTE: This label is supplied in the
information packet shipped with each
furnace.
