Venting

General venting requirements 

Failure to follow all instructions can result in flue gas 
spillage and carbon monoxide emissions, causing 
severe personal injury or death. 

Inspect existing chimney before installing furnace. 
Clean chimney thoroughly. Replace or repair 
chimney if visual inspection indicates chimney may 
be unsuitable for use. Insufficient draft can cause 
flue gas leakage and carbon monoxide emissions. 
Failure to clean or replace perforated pipe or tile 
lining and/or patch mortar and joints can cause 
severe personal injury or death. 

x

PLB furnaces are designed to operate with an over-fire draft of 
-0.01” to –0.02” w.c. Proper draft for these oil furnaces may be 
achieved using either a conventional chimney (natural draft) or a 
power vent (sidewall) system that has been properly designed 
for use with oil-fired equipment. Power vent manufacturer’s 
instructions must be followed. 

x

Use vent material approved by local codes for oil-fired burners. 
In their absence, refer to : 

x

NFPA 31, Installation of Oil-Burning Equipment. 

x

NFPA211, Standard for Chimneys, Fireplaces, Vents and 
Solid Fuel Burning Appliances. 

x

In Canada, refer to CSA B139, Installation Code for Oil-
Burning Equipment. 

x

NFPA-211 requires chimney to be lined before connected to 
furnace.

x

To prevent downdrafts, extend chimney at least 3 feet above 
highest point where it passes through roof and 2 feet higher than 
any portion of building within 10 feet. Increase chimney cross-
sectional area and height at least 4% per 1,000 feet above sea 
level. 

x

Provide minimum clearances from vent (flue) pipe to 
combustible material : 

x

Single-wall vent – 18 inches minimum 

x

Type “L” double-wall vent – 6 inches minimum 

Oversized chimneys, outside masonry chimneys 
and/or derated inputs can result in condensation in 
chimney. 

Connect venting 

Long horizontal vent runs, excessive number of tees 
and elbows, or other obstructions restricting 
combustion gas flow can result in the possibility of 
condensation, flue gas leakage and carbon 
monoxide emissions, which can lead to severe 
personal injury or death. 

The horizontal vent must slope upwards, away from the furnace, 
a minimum of ¼ inch per foot. 

Connection must be made above bottom of chimney to avoid 
blockage. Vent pipe must not enter chimney far enough to cause 
obstruction. Use thimble or slip joint where vent pipe enters 
chimney to allow removal for cleaning. 

When burner and furnace are properly installed, draft overfire 
will be approximately –0.01” to –0.02” w.c. Install barometric 

Connect venting 

(continued)

control in vent, per control manufacturer’s instructions, when 
excess draft needs to be relieved or to comply with applicable 
codes and regulations. Use draft gauge to adjust proper 
opening.

An induced draft fan for the chimney may be necessary if : 

x

Excessive resistance to flow of combustion gases can be 
expected. 

x

Cross-sectional area of chimney is smaller than minimum 
recommended.

x

Chimney height is less than recommended. 

x

When using induced draft fan seal all vent joints and 
interlock burner with fan operation. 

Vent dampers 

Do not install a thermal-type vent damper on this 
furnace. Failure to comply could result in severe 
personal injury, death or substantial property 
damage. 

If vent damper is required, use only a motorized vent 
damper, installed and wired to the furnace following 
the vent damper manufacturer’s instructions. 

Barometric draft control 

Install barometric control in vent, per control manufacturer’s 
instructions, when excess draft needs to be relieved or to comply 
with applicable codes and regulations. Use draft gauge to adjust 
proper opening. 

Install barometric draft control in vent pipe at least one foot from 
the furnace vent connection, preferably in the highest part of the 
vent pipe before the vent enters the chimney. If headroom 
doesn’t provide enough clearance to locate the control at least 
one foot from the vent connection, install an elbow at the furnace 
and mount the control in a horizontal pipe at least one foot from 
the elbow. Install an elbow after the control to turn vertically. 

The barometric draft control must be located in the same room 
as the furnace to operate correctly. 

Ensure the barometric draft control is accessible. Adjust the 
damper to obtain the correct overfire draft, as described in this 
manual and the burner manual.
