design-certified to be resistant to the action of the LP gases should be used on all
threaded joints.
The burner is setup to be piped to the gas supply through the left-hand side of the
furnace. For service purposes, it is recommended the gas union be located inside the
furnace.
A drip leg must be used on both propane and natural gas installations immediately
upstream of the furnace in order to trap oil, condensate, and other impurities which
might otherwise lodge in the gas valve, or plug the main burner orifice. A drip leg shall
be provided at the outlet of the gas meter when there is excessive condensation
between the gas meter and the furnace.
Failure to install drip leg(s) may void the manufacturer’s limited warranty on the furnace.
For natural gas, the maximum supply pressure is 14.0 in. W.G. and the minimum
supply pressure, for purposes of input adjustment, is 5.5 in. W.G.
For propane gas, the maximum supply pressure is 14.0 in. W.G. and the minimum
supply pressure, for purposes of input adjustment, is 11.0 in. W.G.
I. ELECTRICAL WIRING
:
When testing electrical equipment, always follow standard electrical
procedures and precautions.
All electrical wiring must be installed in strict accordance with local ordinances and
