RECOMMENDED ACCESS
FOR SERVICE
Furnace 25.4 mm (1”)
Sides
Supply plenum, warm air duct within 6 ft of furnace 25.4 mm (1”)
Back Furnace 25.4 mm (1”)
Top Furnace casing or plenum 25.4 mm (1”) 0.6 m (24”)
Bottom Furnace – combustible floor ** 0” **
Front Furnace 0.6 m (24”)
* See Part 1 Section 4.3 for Direct Vent application clearances.
** Combustible floor requires accessory bases CFB-1 or HFB-1.
1.3.1) Location
Position the furnace as closely as possible to the chimney or vent
terminal, providing ample clearance to permit easy accessibility for
cleaning the inside of the furnace, the removal of filters, blower,
motors, controls and flue connections.
This furnace is approved for reduced clearances to combustibles.
Therefore, it may be installed in an alcove, closet, or crawl space.
Clearances indicated on the rating plate must be respected.
In the downflow position, this furnace is approved for installation on
combustible floors only when the accessory No CFB-1 "Combustible
Floor Base" is used.
In the horizontal position (air left or right), this furnace is approved for
installation on combustible floors only when the accessory No. HFB-1
"Horizontal Floor Base" is used.
In the horizontal position (air left or right), this furnace may be
suspended using an angle iron frame with threaded rod hangers.
Appropriate calculations, considering the weight of the furnace and the
frame must be made.
However, do not install furnace directly on carpet or other combustible
material, which can trap air under the floor.
The furnace must be installed level for safe and quiet operation.
CAUTION
Do NOT operate the furnace in a corrosive atmosphere
containing chlorine, fluorine or any other damaging
chemicals. Refer to Part 1, section 5.2.
1.4) VENTING
1.4.1) General
The furnaces can be vented in several ways:
Chimney Vented
Using the Beckett AFG or Riello 40-F burner, the furnaces can be
chimney vented with or without a barometric damper. The unit will
operate at a
negative overfire draft and flue draft.
WARNING
Poisonous carbon monoxide gas, fire and
explosion hazard.
Read and follow all instructions in this section.
Failure to properly vent this furnace can cause
bodily injury or death, property damage.
Side-wall Vented
Using the Beckett AFII or Riello 40-BF burner with the integral pre-
and post-purge controls, the system can be side-wall vented with the
new DV-2000™ venting system for maximum efficiency and without
the use of a side-wall power vent. The unit will operate at a
positive
overfire draft and flue draft.
WARNING
Poisonous carbon monoxide gas hazard.
Never vent this furnace together with another
combustion appliance when side-wall venting.
To do so may result in asphyxiation and death to
the occupants
1.4.2) Chimney installations
When set up for chimney venting, this furnace is certified for use with
an L-vent, A-vent, tile-lined and metal-liner-tile lined chimney, and can
be vented both with and without a barometric draft damper. However,
this furnace is not approved for use without a barometric damper if it is
to be vented together with another oil-fired appliance such as a water
heater.
With barometric damper
This furnace may be vented into a chimney of suitable size and
adequate chimney base temperature, as specified in the Installation
Code. When a barometric damper is used, the basement air entering
the damper reduces the possibility of vent condensation. The relevant
excerpt from the code is found in this section and can be used as a
guide where local or national codes do not exist. One option, to
increase the chimney base temperature, is to use vent connection
insulation.
