The required minimum clearances for this furnace are specified
in table #1.

The furnace should be located as close as possible to the chimney to
keep vent connections short and direct.  The furnace should also be
located as near as possible to the center of the air distribution system.

CAUTION

Do 

NOT

 operate furnace in a corrosive atmosphere

containing chlorine, fluorine or any other damaging
chemicals.  Refer to Part 1, section 5.2.

WARNING

WARNING

Electrical shock hazard.

This furnace is not watertight and is not designed
for outdoor installation.  This furnace shall be
installed in such a manner as to protect the
electrical components from water.

Outdoor installation would lead to a hazardous
electrical

 

condition and to premature furnace

failure, property damage, bodily injury or death.

WARNING

WARNING

Poison carbon monoxide gas, fire and explosion
hazard.

Read and follow all instructions in this section.

Failure to properly vent this furnace can result in
property damage, personal injury and/or death.

CAUTION

When the furnace (chimney installation) is co-vented
with other combustion appliances such as a water
heater, the allowable venting materials (i.e. L-Vent etc.)
for use with those appliances should also be
investigated.

The oil furnaces are certified for use with L-vent, A-vent, tile-lined and
metal-liner-tile-lined chimneys.  The appliance may be installed in a
chimney of the proper size and adequate chimney base temperature
as specified in the Installation Code. The relevant excerpt from the
code is found in this section - Use it as a guide when local or national
codes do not exist.

Flue pipe sizing:

The following table is an except from the installation code and
indicates permitted flue sizes and minimum base temperatures for
circular flues in chimney with thermal resistance less than R6 (6 ft

hr

•°

F / Btu).  Where a new appliance, burner, or chimney is installed,

chimney vent sizes and maximum flue-gas temperatures (measured at

the chimney connector with the barometric damper shut, after 5
minutes of operation) shall comply with the table #2.

WARNING

WARNING

Poison carbon monoxide gas hazard

Never install a hand operated damper in the vent
pipe.  However, any Underwriters Laboratories
listed electrically operated automatic type vent
damper may be installed if desired.  Be sure to
follow instructions provided with vent damper.
Read and follow all instructions in this section.

Failure to properly vent this furnace or other
appliances can result in property damage, personal
injury and/or death.
