The gas line should be supported so that no strain is placed on the unit. Pipe compounds which
are not soluble to liquid petroleum gases must be used on threaded joints.
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 (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing the 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 (3.5 kPa).
For additional gas piping information, including pipe sizing and drip leg installation, refer to
Indoor Gas-Fired Duct Furnace Installation and Service Manual.
For additional piping information, refer to the National Fuel Gas Code Z233.1 (latest edition).
IIm mp po orrtta an ntt:: If the gas duct furnace is to be fired with LP gas, consult local LP gas dealer for piping
size information.
IIm mp po orrtta an ntt:: Unit installation for use with propane (bottled) gas must be made by a qualified LP
gas dealer or installer. He will insure proper joint compounds are used for making
pipe connections; that air is purged from lines; that a thorough test is made for leaks
before operating the unit; and that it is properly connected to propane gas supply
system.
Before any connection is made to an existing line supplying other gas appliances, contact the
local gas company to make certain that the existing line is of adequate size to handle the
combined load.
Check all connections for leaks with soap solution.
Modulating Gas Control (Optional)*
• E Elle eccttrro on niicc
– On units equipped with electronic modulating control, follow control manufacturer’s
installation instructions for sensing of outlet air temperature.
