CONTROLS
All controls are preassembled at the factory.
The normal manifold pressure should be 3.5" w.c. on Natural
Gas and 10" w.c. on Propane Gas. The maximum inlet
pressure in the gas supply pipe should never exceed 14" w.c.
on Propane Gas or 7.0" w.c. on Natural Gas.
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 psig.
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig.
The minimum inlet pressure in the gas supply pipe should
be 5.0" w.c. on Natural Gas or 11" w.c. on Propane Gas, "for
purpose of input adjustment".
The appliance is orificed at the factory for elevations between
sea level and 2,000 feet. If installed above 2,000 feet, the BTU
input must be reduced 4% per 1,000 feet that the furnace is
above sea level. See the following orifice chart for the proper
orifice for a specific elevation. The orifice(s) will have to be
drilled to correct size by a qualified installer, service technician
or the gas supplier.
