These instructions are intended for use by qualified individu-
als specially trained and experienced in installation of this
type of equipment and related system components. Installa-
tion and service personnel are required by some governing
bodies to be licensed. Persons not qualified should not
attempt to install or service the equipment, nor interpret
these instructions. These furnaces must be installed in
accordance with local codes and ordinances.
These furnaces are high quality, direct vent furnaces that are
convertible from power oil to power gas. The PO models are
Power Oil. The PG models are Power Gas models . Gas
models are designed for operation with natural or LP. gas.
The furnaces are Listed by Underwriters Inc. for use in
manufactured (mobile) homes and recreational vehicles
and as a central furnace, special type when installed with
model CB200A outlet Air base.
Standard Flue Furnaces
The current line of furnaces using the standard flue system
are the CMF series. This is a heating only, sealed combus-
tion furnace, which draws its combustion air from under the
home via a combustion air duct and vents the flue gases
through the standard roof jack. This furnace must be in-
stalled with the MA-100 or MA-200 base, the SRJ series roof
jack, and the vent pipe used in conjunction with the SRJ roof
jack to meet U.L. requirements.

WARNING
This furnace must be installed by a qualified
installing agency and in accordance with local
codes and ordinances. Failure to properly install
the furnace, base assembly, and venting system
as described in the Installation Instructions may
damage the equipment and/or the home, can
create a fire or asphyxiation hazard, violates U.S.
Listing requirements, and will void the warranty.
!
2. With power on at the fuse box, test the line voltage
conductors to the ground with a voltmeter set on the
proper scale.
a. L1 to ground should read 120 Volt AC ±10%.
b. Neutral to ground should read zero volts.
NOTE: Test with power on and conductors disconnected
from furnace connections.
3. If a reading other than above is read, reverse conductors.
CAUTION
Be careful to avoid electrical shock hazard.
