Duct Furnace Installation and Service Manual.
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
Separated Combustion Indoor Gas-Fired Duct Furnace Installation and Service Manual.
For additional piping information, refer to the National Fuel Gas Code Z233.1 (latest edition).
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.
