SAFETY CONSIDERATIONS AND GUIDELINES
TIPS FOR MAINTAINING HIGH PERFORMANCE
DO NOT ALLOW ANY UNAPPROVED MATERIAL INTO THE OIL STORAGE TANK.
Explanaon:
Material placed in the oil storage tank will eventually be delivered to the burner. Anfreeze and
water will not ignite and will cause the heang equipment to shut down.
DO NOT USE EXHAUST FANS THAT CREATE A VACUUM IN THE BUILDING.
Explanaon:
A backdra at the heang equipment will damage crical burner components. If your shop
requires exhaust fans there must be adequate make up air so that the furnace can maintain a
proper natural dra. If there is insufficient make up air, install make up air louvers or use a relay
to open the wall thermostat circuit to ensure the burner does not fire when an exhaust fan is in
use.
TURN OFF POWER TO THE BURNER IF A CALL FOR HEAT IS NOT EXPECTED FOR
MORE THAN A WEEK.
Explanaon:
If the green power light is “on” at the burner, the oil temperature is being maintained by the
200W heater element. If this oil temperature is maintained over a long period of me (like over
the summer months) without a call for heat, the nozzle adapter heater block is more likely to
accumulate carbon build up which may cause a plugged nozzle. Flip the breaker “off” at the panel
or turn the Burner Power Switch “off” located on the juncon box on top of the unit.

Installing the chimney components:
WARNING: Double wall “Class A” insulated stack must be used through any building
penetration and for any exterior stack. Unapproved stack material and/or installation
can create a fire hazard. Contact Clean Energy Heating Systems, LLC to purchase
approved stack material for your installation.
CAUTION: Using single wall stack on the exterior of your building will cause the stack
gases to cool rapidly and adversely affect the natural draft of the furnace. This will
create a back draft and may damage critical burner components.
(1) Refer to Figure 14 for a typical through-the-roof chimney illustration and Figure 15 for a
typical through-the-wall chimney illustration.
(2) Observe the following requirements when installing the chimney:
• The CE-140, CE-180 and CE-250 furnace models require 6” I.D. stack components.
• The CE-330 and CE-440 furnace models require 8” I.D. stack components.
• Have a minimum of 10 feet vertical chimney to ensure -.02” w.c. draft over fire.
• Keep horizontal runs short. Slope any horizontal sections at least 1/4” per foot.
• Keep the stack installation simple. Multiple turns and horizontal runs will reduce the
natural draft of the furnace which may damage critical burner components.
(3) Single wall stack may be used inside the building. Observe proper clearances from
combustibles. Do not put single wall stack in areas that may create a burn hazard to
personnel.
(4) Install a barometric damper, as shown in Figures 15 and 16, so that proper draft can be
maintained. Follow the instructions provided with the damper for proper installation.
(5) Use double wall “Class A” insulated stack material when making a penetration through the
ceiling, roof or side wall of your buiding. Install proper flashing around the exterior
penetration of the stack to make a water tight seal.
(6) Install a “Class A” non-restrictive stack cap only.
CAUTION: If your building utilizes an exhaust fan, ensure that there is adequate
make-up air available. Lack of make-up air will create a vacuum in your building
which will result in a back draft at the furnace. A back draft will damage critical burner
components.
