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.
