Insert Stove Venting - Whitfield quest Owner's Manual And Operating Instructions

FREESTANDING STOVE VENTING continued
Ninety-degree elbows accumulate fly ash and soot, reducing the exhaust flow and lowering the
performance of the stove. Horizontal runs of pipe will collect fly ash as well. It is recommended
that a single or double clean-out tee be installed at every 90 degree turn so that fly ash can
accumulate at the bottom of the tee. Total length of horizontal vent must not exceed 25 feet
(7.7m; see Determining Equivalent Pipe Length on page 20).
If a 90 degree turn connects a vertical run of pipe to a horizontal run (as you follow the exhaust
away from the stove), a tee is not required. At any other 90 degree turn, installation of a clean-
out tee is recommended to permit periodic cleaning of both the horizontal and vertical runs of
pipe.

INSERT STOVE VENTING

A 3" single-wall, stainless steel flexible or rigid exhaust pipe may be used for insert installa-
tions in place of double-wall, type "L" vent. The pipe should be connected to the supplied
clean-out tee. High-temperature silicone sealant should be used at the vent pipe connections to
ensure a "gas-tight" seal.
When venting through an existing chimney (masonry or factory built) the chimney must be
cleaned. All creosote, dust and ash must be removed (see page 32 for more information on
preparing the fireplace for the insert installation).
The "L" vent or single wall stainless exhaust system must be installed so as to be gas-tight!
The vent manufacturer's installation procedures must be followed. In addition, pipe connections,
joints and all pipe seams within the home should be sealed with high-temperature, vulcanized
silicone sealer (RTV).
If an insert is to be installed into an unlined masonry chimney, the 3" or 4" rigid or flex pipe
must be extended to the top of the existing chimney. All insert installations must be lined
to the top of the chimney (10 feet minimum length above the stove) with stainless flex pipe
or a pellet vent system.
After the chimney has been lined to the top of the existing flue, any opening between the exist-
ing chimney and the pipe/vent liner should be sealed with a metal plate. Use a clamp or other
fixture above the sealing plate to support the weight of the vent system.
