H. GAS PIPING
:
Because of the potential of the odorant to fade, a gas leak may not be
detected by smell. If this furnace is installed below grade, contact your gas
supplier for a gas detector.
supplier for a gas detector.
:
With the gas piping pressurized, all gas piping connections must be
leak tested using a strong soap and water solution. Any leaks must be repaired
immediately after turning off the gas supply. A final test for gas leakage must be
made after purging the gas line.

made after purging the gas line.
:
DO NOT wet electronic components during the leak test. Wetting
electronic components may damage circuitry and cause a hazardous situation.
Dry moisture from all leads and terminals if wetting occurs. Wait at least 24
hours for the circuit to fully dry before energizing the system.

The furnace and its gas valve must be disconnected from the gas
supply during pressure testing of the gas supply system at pressures in excess
of 1/2 PSIG (13.9 inches W.G.). The furnace can be isolated from the gas supply
by closing the manual gas shutoff valve serving the appliance at test pressures
equal to, or less than, 1/2 PSIG or (13.9 inches W.G.).

Copper and brass tubing and fittings (except tin lined) shall not be
used if the gas contains more than a trace (0.3 grains per 100 cubic ft.) of
hydrogen sulfide gas. Check with your gas supplier.
hydrogen sulfide gas. Check with your gas supplier.
Sizing and installation of fuel lines must be in accordance with federal, state, and local
regulations.
A qualified installer or service person must install all gas piping and perform all required
testing.
Piping from the natural gas meter to the furnace shall be in accordance with
requirements of the local gas utility. Piping from the propane tank to the furnace must
follow the recommendations of the gas supplier. In the absence of local codes
governing gas piping selection and installation, follow the National Fuel Gas Code,
ANSI Z223.1 / NFPA 54-1999, or latest edition.
A readily accessible, manual gas shutoff valve (design-certified for the applicable gas)
with a non-displaceable rotor member shall be installed within six (6) feet of the
furnace.
A pipe union, or flanged connection, shall be provided directly up stream of the burner
to allow burner removal. Unions must be of a ground joint type or flange-jointed type
using a gasket resistant to the corrosive effects of LP gases. Pipe dope or sealant
