FIRE OR EXPLOSION HAZARD.
Failureto properlyinstallmetalgas connectorcould
result in death, bodily injury and/or property
damage.
A flexible corrugated metal gas connector must be
properlyinstalled, shall not extend through the side
of the furnace, and shall not be used inside the
furnace.
Black iron pipe shall be installed at the furnace gas
control valve and extend a minimum of 2²

WARNING
Additional LP Piping Requirements
· Have a licensed LP gas dealer make all connections at stor-
age tank and check all connections from tank to furnace.
· Ifcoppertubing is used, it MUST comply withlimitation set in
LocalCodes,orin the absence oflocal codes, the gascodes
of the country having jurisdiction.
· Two--stage regulation of LP gas is recommended.
FIRE OR EXPLOSION HAZARD.
A natural gas or LP gas leak ignited by an open
flame or spark could result in death, personal
injury and/or property damage.
Natural gas is lighter than air and will rise.
Liquefied petroleum (LP) gas is heavier than air
and will settle and remain in low areas and open
depressions.
Thoroughly ventilate area and dissipate gas. Do
NOT use a match or open flame to test for leaks, or
attempt to start up furnace before thoroughly
ventilating area.

Final Check
· Test all pipe for leaks.
· If orifices were changed, make sure they are checked for
leaks.
· During pressure testing of gas supply piping system:
a. If test pressure does not exceed
1
/
2
² psi, isolate the
furnace from the gas supply piping system by closing the
equipment shutoff valve.
b.Iftestpressureexceeds
1
/
2
² psi,thefurnaceanditsmanual
equipment shutoff valve must be disconnected from the gas
supply piping system.
· To check for leaks apply soap suds or a liquid detergent to
each joint. Bubbles forming indicate a leak.
· Donot use an open flame to test for gas leaks. Fire or explo -
sion could occur.
· Correct even the smallest leak at once.
