Pellet fireplace inserts and freestanding stoves are often vented into existing masonry and
factory-built fireplace and wood stove chimneys (Fig. 1). The chimney should be inspected before
installation to ensure that it is clean, mechanically sound, and meets local safety code
requirements. The appliance manufacturer's installation instructions may require relining the
chimney with an approved metal liner, pipe, or PL vent. Vents or grilles on the face of factory-built
fireplaces which provide cooling air to the outside jacket of the fireplace must not be blocked.
Cleanout access for future maintenance should be considered.
Floor protection
Unless you already have a suitable hearth in place on which to put your stove, you'll need to have
floor protection laid down that meets the manufacturer's specs, including minimum size and type of
material. If in doubt get professional advice. Built-in appliances may need extra protection such as
an air space between the appliance and the floor protector.
Venting
Find out if this likely to be limited by factors such as obstructions above vertical venting through the
ceiling and roof or by the distance to an outside wall for horizontal venting.
Outside air for combustion (if needed) This has to be drawn from an approved location.
Space requirements
There are minimum specified clearances between the stove and combustibles. But allow more
space than the minimum to give enough room to operate and service the stove easily.
Electrical requirements
Because a pellet stove needs electrical power, it has to be located near a properly wired outlet of
the correct voltage, ground, and polarity. It's also essential that the circuit to be used has a
properly rated circuit breaker.
The options for venting layout fall into the following categories:
· Sidewall horizontal venting (Fig. 2)
Invariably the least expensive venting system. Disadvantage of potential smoke spilling into the
house in the event of a power outage or component failure, or house depressurization.
· Horizontal vent with backup vertical venting (see Fig. 3)
Preferred horizontal method that avoids venting problems associated with unexpected appliance
shutdown.
· Vertical venting through the ceiling and roof (Fig. 4 and 5)
Has the advantages of keeping vent gases warm and of providing natural draft to prevent problems
in an unexpected shutdown.
· Venting into existing chimney (see Fig. 1)
Stove manufacturers provide recommendations for venting into masonry and factory-built
chimneys, which may include partial or full chimney relining.
· Natural Draft
All vents for appliances designed without mechanical exhaust fans must meet stove manufacturer's
requirements for minimum draft and must terminate above the roof.
· Horizontal and vertical (Fig. 6)
Extends from the top or back of the appliance, penetrates the wall, turns up to penetrate the eave
and roof.
