• 

Install a drip leg to trap dirt and moisture before it can 

enter the gas valve.  The drip leg must be a minimum 

of three inches long.

• 

Install a 1/8” NPT pipe plug fitting, accessible for test 

gage connection, immediately upstream of the gas 

supply connection to the furnace.

• 

Use two pipe wrenches when making connection to 

the gas valve to keep it from turning.  The orientation 

of the gas valve on the manifold must be maintained 

as shipped from the factory.

•  Install a manual shutoff valve between the gas 

meter and unit within six feet of the unit.  If a union 

is installed, the union must be downstream of the 

manual shutoff valve, between the shutoff valve and 

the furnace.

• 

Tighten all joints securely.

• 

Connect the furnace to the building piping by one of 

the following methods:

– 

Rigid metallic pipe and fittings.

– 

Semi-rigid  metallic  tubing  and  metallic  fittings.              

Aluminum alloy tubing must not be used in exterior 

locations.

– 

Use listed gas appliance connectors in accordance 

with their instructions.  Connectors must be fully in 

the same room as the furnace.

– 

Protect connectors and semi-rigid tubing against 

physical and thermal damage when installed.  

Ensure aluminum-alloy tubing and connectors are 

coated to protect against external corrosion when 

in contact with masonry, plaster, or insulation, or 

subjected to repeated wetting by liquids such as 

water (except rain water), detergents, or sewage.

Upflow Installations

A ground joint union, drip leg, and manual shutoff valve must 

also be supplied by the installer. In some cases, the installer 

may also need to supply a transition piece from 1/2” to another 

pipe size.

When the gas piping enters through the side of the furnace, 

the installer must supply the following fittings starting from 

the gas valve:

• Nipple

• Elbow

• 

Straight pipe to reach the exterior of the furnace.

•   A ground joint union, drip leg, and manual shutoff 

valve

 

must also be supplied by the installer.

Counterflow Installations

When the gas piping enters through the side of the furnace, 

the installer must supply , the following fittings starting from 

the gas valve:

• Nipple

• Elbow

• 

Straight pipe to reach the exterior of the furnace.

A ground joint union, drip leg and manual shutoff valve must 

also be supplied by the installer. 

Gas Piping Checks 

Before placing unit in operation, leak test the unit and gas 

connections.

WARNING

Check for leaks using an approved chloride-free soap and 

water solution, an electronic combustible gas detector, or 

other approved testing methods.

NOTE:

  Never exceed specified pressures for testing.  Higher 

pressure may damage the gas valve and cause subsequent 

overfiring, resulting in heat exchanger failure.
Disconnect this unit and shutoff valve from the gas supply 

piping system before pressure testing the supply piping system 

with pressures in excess of 1/2 psig (3.48 kPa).
This unit must be isolated from the gas supply system by 

closing  its  manual  shutoff  valve  before  pressure  testing  of 

gas supply piping system with test pressures equal to or less 

than 1/2 psig (3.48 kPa).
