
This installation should comply with requirements of CAN/CSA-B365, and changes are made
to the central furnace, changes must comply with CSA B139 (for oil-fired), C22.1 (for electric),
or CAN/CGA-B149.1 or CAN/CGA-B149.2 (for gas-fired).

This add-on furnace must only be installed on a furnace duct system and chimney that are in
good operating condition.
IV. Flue Systems
Masonry Flue System:
A good chimney is essential. A masonry chimney must be built with a low heat
masonry material. It is important to make sure that the masonry chimney is structurally sound and on a
solid foundation. The masonry chimney must have a liner installed within the chimney construction. An
unlined chimney is not safe with solid fuel systems, and may result in a house fire. The liner may be a
structurally
sound clay liner or a stainless steel liner. If using an existing masonry chimney, be sure to
have the chimney examined and cleaned by a chimney professional. The structural foundation of the
chimney and liner are important. If the existing clay liner is cracked or damaged, it is recommended to re-
line the chimney with a stainless steel liner or other chimney relining system. Be sure the masonry
chimney is compatible with the local building codes and requirements. It is important to note that you can
only have one appliance per chimney, and it is not permissible to connect your Hitzer Energy Master II
furnace to a chimney that is servicing another appliance.
Factory Built System:
A good chimney is essential. The factory built chimney must be a Class A: High Temperature chimney UL
listed to UL 103 (CAN/ULC-S629-M87) Type HT. It is required for this Class A chimney to be listed and
labeled under the UL standards. If using an existing factory built Class A chimney it must be inspected
and cleaned by a certified chimney professional, before use. With Factory Built Chimneys, clearances
and distance requirements are required per chimney style. Be sure to follow the manufacturer’s
clearances and regulations. It is also important to abide by the rules and regulations of local jurisdictions
upon chimney installation. Like masonry chimneys, you can only have one appliance per chimney, and it
is not permissible to connect your Hitzer Energy Master II furnace to a chimney that is servicing another
appliance.
Flue Requirements: It is required to have a chimney that is built according to the chimney
manufacturer’s specifications and meets local building codes. It is also required to have your chimney
inspected and cleaned by a certified chimney professional before your Hitzer Energy Master II furnace
installation, and periodically during the heating season. When wood is burned slowly, it produces tar and
other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors
condense in the relatively cool chimney of a slow-burning fire. As a result, creosote residue accumulates
on the flue lining. When ignited, this creosote makes an extremely hot fire, the results of which can be
tragic. If material has accumulated, it should be removed immediately to reduce the risk of a chimney fire.
An Anthracite coal fire, as a general rule, does not produce creosote so it should not add to a creosote
buildup. It can however get hot enough to ignite an existing buildup thus causing a chimney fire.
IF A CHIMNEY FIRE DOES OCCUR: Notify all the occupants of the house and call the fire department
immediately. Turn the power to the furnace turned off, and any draft controls should be closed. The
barometric damper should be blocked then exit the house at once!
Flue Size: The proper flue size is very important. The proper flue size is essential in order to have the
correct amount of draft required to operate the Hitzer Furnace. The diameter of the flue size including
chimney liner should never be less than the diameter of the flue exhaust collar on the Hitzer Furnace. The
flue size for the Stoker Furnace should be a minimum of 6 inches in diameter
The flue size also has a maximum size of inches in order to sustain the desired draft. For an interior
chimney the flue and chimney liner size
cannot be larger than 3 times the square inches of the flue
exhaust collar on the Hitzer stove. For an exterior chimney that has at least one side exposed to the
exterior of the house the flue and chimney liner
cannot be more than 2 times the square inches of the
flue exhaust collar of the Hitzer Furnace. Also keep in mind the warmer the chimney is the better the
draft.
