leak check
notE:
Optional fuel inlet lines are available for all gas
furnace models to permit the addition of a 1/2” F.P.T.
shut-off valve above the floor.
The gas supply to your home will either be Natural Gas
or L.P. (bottle gas). Your furnace is factory equipped to
operate on Natural Gas. If your gas supply is L.P. (bottle
gas), you must contact a qualified serviceman or gas
supplier to convert the furnace. Instructions for conversion
to propane are shown on
.
For natural gas operation, the furnace is designed for 7”
W.C. inlet pressure. Pressure is reduced to 3 1/2” W.C.
by the pressure regulator in the gas valve. The maximum
inlet pressure for the valve is 7” W.C and the minimum
inlet pressure is 4.5” W.C.
For L.P. gas, pressure to the gas valve must be more than
11” W.C. but not more than 13” W.C. Pressure is reduced
to 10” W.C. by the pressure regulator in the gas valve.

Figure 26. typical Gas Piping
After the gas piping to the furnace is complete, all
connections must be tested for gas leaks. This includes
pipe connections at the main gas valve, emergency
shutoff valve and flexible gas connectors (if applicable).
The soap and water solution can be applied on each
joint or union using a small paintbrush. If any bubbling is
observed, the connection is not sealed adequately and
must be retightened. Repeat the tightening and soap
check process until bubbling ceases.
IMPoRtant notE:
When pressure testing gas supply lines at pressures
greater than 1/2 psig (14 inch W.c.), the gas supply
piping system must be disconnected from the furnace
to prevent damage to the gas control valve. If the test
pressure is less than or equal to 1/2 psig (14 inch
W.c.), close the manual shut-off valve.
oil tank & Piping Installation
The following procedures are recommended as good
practice. However, requirements of local codes and
ordinances, H.U.D. Manufactured Home and Safety
Standards or National Fire Protection Association must be
satisfied, where they apply, for an approved installation.
• Use a tank capacity suitable for the application with a
weatherproof, capped fill opening and a shielded vent
to let in air as fuel is used.
