Legacy Stoves VF2500, Installation And Operator'S Manual

Page: 12 / 37

THE STOVE MUST BE CONNECTED TO
ITS OWN CHIMNEY. DO NOT CONNECT
THIS FURNACE TO A CHIMNEY FLUE
SERVING ANOTHER HEATING DEVICE.
MANUAL DAMPERS OR “HEAT SAVERS”
MUST NEVER BE INSTALLED IN THE FLUE
PIPE. IMPROPER OPERATION COULD
RESULT IN DEATH.
CAUTION: THE CHIMNEY MUST BE A
CLASS “A” CHIMNEY, IN GOOD OPERATING
AND CLEAN CONDITION.
NOTE: THE USE OF ALUMINUM TYPE “B”
GAS VENT FOR SOLID FUELS IS UNSAFE
AND PROHIBITED BY THE NATIONAL FIRE
PROTECTION AGENCY CODE.
ere are three types of class “A” chimneys:
1. Masonry with tile liner, to include brick or
stone. It must be supported on grade level
foundation.
2. Insulated, manufactured chimney, listed or
certi6ed by a national test agency.
3. Triple-wall metal class “A” chimney, listed or
certi6ed by a national test agency.
The chimney selected must comply
with the requirements for type HT
chimneys with UL 103 or ULC S629
ratings. Do not use makeshift
compromises during construction.
If your masonry chimney has not been used for
some time, have it inspected by a quali6ed person. If a
listed or certi6ed manufactured chimney is to be used,
make certain it is installed in accordance with the
manufacturer’s instructions and all local and state
codes.
Masonry Chimneys
If you plan on using a preexisting masonry
chimney, have it thoroughly inspected and cleaned.
Any faults which make the chimney unsafe and
unusable must be repaired prior to use.
ese can
include improper height, structural defects, blockages,
inadequate clearance to combustibles, unsealed
openings into other rooms of the house, signs of
creosote or smoke leakage, a loose or absent clean-out
door, or absence of a liner.
When connecting to a masonry chimney, several
provisions are standard. First, whether the chimney
connector is vented to the chimney through a thimble
or a breech pipe, neither must pass beyond the inner
surface of the chimney liner, and both must be 6rmly
cemented in place with refractory cement. (A thimble
is a masonry pipe which is inserted through the
chimney wall, and is frequently the preferred method;
a breech pipe is a piece of steel pipe used the same
way.) In Canada, a breech pipe has ridges or
protrusions to lock it 6rmly into the refractory
cement. In either case, the chimney connector vents
to the chimney through the thimble or breech pipe.
See wall pass-through information in the section on
stove pipe.
